DESCRIPTION

SYSTEM AND METHOD FOR CREATION OF INSTRUCTIONAL VIDEOS THROUGH THE

USING COMMAND SEQUENCES

TECHNIQUE SECTOR

The present invention belongs to the sector of instructional videos, these instructional videos aim to show a process, transfer knowledge, explain concepts, or show someone how to do something.

Some of the most common types of instructional videos are:

• Training pills or micro-videos that are short videos focused on teaching about a specific and particular concept.

• Video tutorials are the basic teaching method to teach a process or give procedural instructions.

• Training videos that are designed to improve the skills of employees in a company or students during a course.

• Explanatory videos that explain a topic or concept in a visual and entertaining way.

• The recording of a class, lecture, or presentation to make the instructional content available for the audience to consume or review after the event.

• Screen recordings are short, direct videos composed primarily of screenshots designed to teach someone how to perform a task or share knowledge.

One of the main objectives of instructional videos, apart from transmitting knowledge, is to guide the actions of the person viewing it, presenting to the video observer or video-viewer the instructions to assemble an article, carry out an experiment, build a artifact, organize a game, repair a machine, be more efficient in some vital aspect, code a computer system or carry out any other type of process that involves following specific instructions to achieve it. Many of these instructional videos show the steps to follow and instruct in an activity regardless of its difficulty in performing it. Other instructional videos deal with a scientific, historical, cultural, or commercial concept, deal with a product or service offered by a company, or instruct on any topic of general interest such as news, current affairs, trends, etc.

This invention falls within instructional videos that show digital content generated, created and/or produced by computer software of any type, whether system software or application software. Examples of this type of digital content are any of the following or a combination of any of them: slide presentations, the display of images, graphics or other videos, screenshots with actions performed in computer applications, navigation in Web applications, computer-generated simulations, legends and subtitles, digital avatars and in general, any content that originates from a computer system.

BACKGROUND OF THE INVENTION

In today's information society, it is increasingly necessary to provide its individuals with various teachings and learning digitally. One of the most commonly used digital learning mechanisms today is instructional videos. By watching it and through a series of instructions, the video viewer learns to carry out a certain activity or process in a direct, practical and effective way. Given that these instructions may be aimed at a very wide audience, it is crucial that they use language that is as simple, clear and precise as possible.

It is increasingly common that instead of using manuals, books, talks, conferences, seminars or courses given by teachers or experts, instructional videos are created, where the video viewer is taught gradually, with a series of explanations and also about the steps that must be followed to achieve an expected result, previously indicating the materials, requirements or elements necessary to achieve it. In this sense, the instructional video guides the procedure in a precise, clear and detailed way to be able to learn about a topic, understand a procedure, organize a process, make a dish or recipe, build an artifact, solve a problem, follow a route to a trip, or even serve as online documentation for the use of any type of product or service, among many other types of possible learning.

These instructional videos can be distributed using physical data storage media (CD-ROM, DVD, USB, etc.), through storage on network resources (SAN, NAS, FTP, NFS, etc.) using computer networks (LAN , MAN, WAN, etc.), using file hosting services, and can be published on private or public Internet websites, specific sites for storing and sharing videos, social networks or in repositories with specialized purposes such as File Management Systems. Contents (CMS) or Learning Management Systems (LMS) or in massive open online courses (MOOC), the same video may be simultaneously published or distributed using several of the aforementioned media.

The content of these instructional videos was initially recorded with an analog video camera using real-world elements and linear editing methods to generate the video. Nowadays, digital video cameras are used to record one or some of the channels of the instructional video and later this is edited with computer applications that allow non-linear editing. However, it is increasingly common to create instructional videos with content combining elements from the real world with elements generated by computer systems or it is even possible to create instructional videos that contain entirely constituent content completely generated by computer systems. It must be clarified that today there is no difference between digital content that can be generated by the hardware or software of a computer system. All content generated by computer systems will be called Digital Content in this document.

Examples of these digital contents generated, created and/or produced by a computer system and that can be shown in instructional videos are:

• images with screenshots, or video or videos with screen recording of actions performed on the user interface of one or more desktop, mobile or Web computer applications;

• images and videos edited by a computer system;

• slides displayed from one or more presentations;

• texts, indexes, tables, graphs, images, diagrams, equations, maps, plans, models, vignettes, animations, infographics and any other hypermedia content generated by a computer application;

• computer-generated simulations;

• the titles, annotations and indications;

• the audios with the narration of the corresponding explanations;

• legends and subtitles to facilitate accessibility for users with functional diversity or understanding by speakers of other languages;

• background music and tunes;

• transitions between different elements;

• visual and sound effects;

• graphic and sound elements with the identity of the author (watermarks, distinctive signs, logos, colors, songs, melodies, etc.);

• the secondary video channel or channels with one or more recorded or synthesized presenters with avatars or digital characters exposing the instructional content and/or empathizing with the observer;

• any combination between any of the above elements and any other digital content.

As TABLE 1 shows, instructional videos typically present the following elements sequentially:

• a title for the video and perhaps a brief description accompanied by the name of the author and the date of the video, and any other information relevant to the presentation of the instructional video;

• instructive content, with the necessary explanations and the series of instructions or steps to be carried out to achieve the desired objective proposed by the video. Contains screen recording and playback of the rest of the digital content;

• optionally at the beginning of the instructional video, a prologue element is presented to grab the audience's attention. Sometimes the title is shown before the prologue.

• At the beginning of the instructional video, an introduction or entry can be presented, this being a component of the identity or brand of the author, entity, product, course, etc. It is usually composed of a video fragment with the logo, some animation and melody. Sometimes the title is shown inside the lead;

• sometimes an item is shown with the necessary requirements, ingredients or components, and/or the list of instructions or steps to achieve the desired objective proposed by the instructional video. This element is usually displayed before the beginning of instructional content, although it may sometimes be displayed after it to recap;

• the instructional video can end with an exit or closing part of the instructional video, an identity or brand component of the author, entity, product, course, etc. It is usually composed of a video fragment with the logo, some animation and melody;

• an epilogue before or after the release of the instructional video where conclusions, morals and/or farewell are presented. Sometimes a clip from a related instructional video is referenced or displayed;

• a closing credits at the end of the instructional video listing the cast and crew members of the instructional video. Sometimes the credits are presented at the beginning of the instructional video;

• Occasionally, outtakes or outtakes may be included for the video as a way to engage the audience using something related to the content of the instructional video.

The order of the aforementioned sequential elements may vary as indicated above and/or be permuted according to any other production criteria, with the repetition of some of these elements being even possible during the instructional video. The duration of all these sequential elements is arbitrary depending on the specific production of the instructional video.

In addition, instructional videos present one or more transversal elements that may appear during some, or some, or all of the elements of the instructional video sequence, such as:

• Closed captions or text captions in the same language as the video audio to aid understanding for people who are hearing impaired, for those learning to read, learning to speak a non-native language, for those in a environment in which audio is difficult to hear or is intentionally muted;

• open subtitles with text derived from a transcription or a script of the dialogues or comments on the videos, which always appears at the bottom of the screen, and at the top if there is already text at the bottom of the screen. screen;

• Admonitions are visually appealing blocks labeled “tip”, “note”, “important”, etc. that can appear anywhere in the instructional video;

• watermarks or any other type of marker embedded, covertly or not, in a noise-tolerant signal, such as audio, video or image data. Used to identify copyright ownership; These marks include on-screen logos, informally called flies or logo flies;

• background music with one or more styles of music or sounds, intended mainly to be passively listened to. It is not intended to be the main focus of a viewer, but rather to complement the instructional video;

• the secondary video channel(s) for the instructional video presenter(s) who do the narration and empathize with the viewer;

• The narration or locution of the video by the presenter or a voice-over (voice-over);

The same instructional video can be produced in different languages or using different platforms, devices and/or operating systems to reach different target video viewer groups.

Common examples of using these instructional videos are: training pills on how to perform specific tasks (Micro-Learning); video tutorials (How-to), training and explanatory videos to carry out electronic learning (e-Learning); online seminars with recording of classes, conferences and events for later viewing (Webinars); videographies with screenshots to teach how to perform a task (Screencasts); help on computer applications (Online-help), and technical support for a product (Help-desk), among others.

The creation of these instructional videos requires the selection and preparation of the computer system and its resources (memory, video, etc.) appropriately, the installation of all necessary software and also its prior configuration. Likewise, homogenization of the recording environment is usually required so that different shots, or even different videos, are uniform in colors, preferences and wallpapers. Prior to creating these videos, the author can create a script document so as not to have to recount detailed explanations and steps by heart.

Usually the video with the instructional content is captured by a screen recording tool showing any of the digital content mentioned above. Normally, during the recording of this content, erroneous actions and/or inconsistent effects are carried out by the video creator, such as: erratic mouse movements, typing errors, unexpected pauses, speech errors, etc., making subsequent editing of said content necessary. instructional content to assemble valid recording shots, minimize or mitigate errors, and add the other sequential and cross-sectional elements of the instructional video using a video editing tool. Subsequently, it is possible to create the audio with narration by the author or a professional speaker of the explanations and instructions to follow to add it to the video already recorded previously.

This production by one or more human authors of the instructional video means that its creation requires a time of no less than two orders of magnitude to the duration of the created video, for example, the production of a video of several minutes requires at least several hours. Therefore, this task of creating the instructional video is costly in resources, time and money. Likewise, and due to the constant evolution of knowledge and computer programs, it is common for these instructional videos to become obsolete in a short period of time, making it quite expensive to create a new, renewed version of the instructional video to adapt to a change or improvement in the explanations, adding new digital content, updating to a different version of any of the computer programs in question, correcting any errors detected after the human production of the video, updating the identifying elements or the brand of the video or any other requirement of update because the recording environment of the original video is not always available later, the digital content has not been consolidated or even because the author or authors are not available. Therefore, even the slightest modification of any part of the instructional video is equally costly again in resources, time and money, and often requires the entire creation of the instructional video again due to the aforementioned problems. Therefore, it is not very common to find regularly updated and/or maintained instructional videos but rather instructional videos as they were initially created and obsolete to some degree after some time since their publication.

It would be advantageous to be able to create and isolate the execution environment of the instructional video with a virtual machine or computer system template that was always available to repeat the recording or update it, to be able to install the required software in the necessary version automatically, to display the digital content automatically, determine the positions of the actions on the screen in a non-erratic manner, perform the actions on the screen without delays or delays, systematize the speech synthesis with text-to-speech techniques, generate all variants of the instructional video of automatically in all required languages, platforms, devices, and operating systems.

In general, it would be very advantageous to automate the entire creation of the instructional video and/or any of its sequential elements and/or any of its transversal elements and/or any of the digital content thereof.

It would be even more advantageous to be able to use scripts to define the structure of the instructional videos, their constituent sequential and transversal elements and for the generation or localization of any of the digital content. These scripts could be used to prototype instructional videos, test content updates, automate repetitive tasks, batch process videos, and parameterize the instructional video for the different languages, environments, devices, and operating systems needed and take into account. takes into account the preferences of the authors or the video-viewers.

EXPLANATION OF THE INVENTION

The system for creating instructional videos using scripts of the invention provides a complete instructional video, which has been recorded using the selected language(s) and environment(s), with the required computer programs and applications installed, which includes carrying out the actions indicated on said programs, the narration with the explanations and instructions of the instructional content and the rest of the required digital content. This instructional video includes the different sequential and transversal elements indicated in TABLE 1. The system for creating instructional videos takes as input data a file with the script that contains all the configurations, instructions, steps and other information necessary on the instructional video to be created, all with the cooperation of the method of the invention. Figures 3A and 3B list an example script for the system.

The main advantages of this invention are summarized as follows:

• CONSISTENCY. Manual processes carried out by people generate errors.

Humans are fallible, uncertain and imprecise and memories fail. Communication is difficult and manually creating instructional videos will lead to discrepancies, usually detected at the end of video production. This invention solves all these problems by making the script file the single source of truth (SSOT). This ensures that the same instructions will be implemented over and over again, without discrepancies or variations in an identical manner.

• SPEED. The creation of instructional videos can be automated by a computer system without requiring human intervention. The computer system can perform different tasks faster than the human author and even carry out activities without pauses or in parallel. All of this results in faster and more unattended creation of the instructional video.

• MAINTENANCE. Subsequent changes to the script file due to bug fixes, software version updates, changes to names, logos and any other updates, additions or deletions to any of the digital content are processed in the same way as a video new instructions: from scratch without side effects or incompatibilities or impediments due to reusing, altering, editing, changing the environment, digital content or any of the elements used previously. This makes instructional videos easier to maintain from subsequent changes, updates, additions, deletions and/or corrections.

• REPETIBILITY. The ability to repeat the creation of the instructional video at will is one of the greatest benefits of the invention. It is even possible to create parameterizable instructional videos in your script, which we can recreate anywhere and repeat its creation at any time with the initial or different parameters for various languages, environments, devices and platforms or even to use different identification elements branded.

• TRACEABILITY. By using a version control system (VCS) with the instructional video script files as with any source code file, you have complete traceability of changes to every configuration and every change. This determines who did what and when on the instructional video.

• COMPARISONS and SEARCHES. Instructional videos can be compared to each other, as they are defined solely as script files, allowing the system user to find analogies and differences between different versions of the same instructional video or with other related instructional videos. Also the textual nature of the video definition allows the user to search and find videos by elements, tags, characteristics and content that would not otherwise be possible or would require the use of image and video comparison tools that are more expensive and slow. .

• EFFICIENCY. By using one or more scripts to define the instructional videos, the instructional videos can be implemented in multiple stages, steps or phases. You can also inherit properties and settings from other scripts, reducing the amount of information to supply. Reusable elements can be defined between videos such as the entrance, the exit, etc. in scripts that are imported during the main script and can be used as a template. Even the script creation process can be done between multiple users specialized in their different areas of expertise. This makes the cycle for creating the instructional video more efficient, raising the level of productivity of the video author(s).

For example, considering the environment defined in the script file, there may be system users who use these script files to create and launch test environments, allowing them to install the software in a safe and isolated manner, to test if the instructional video is compatible with new versions or updates. Other users who would like to create multiple interrelated videos for a training consisting of multiple instructional videos can have perfect copies of the environments in which to create their different instructional content at the beginning of each lesson. Other users might adapt a video to a new language, platform, device, environment, or operating system by focusing only on actions specific to that language, platform, device, environment, or operating system and not those common to all others.

According to the invention, the system for creating instructional videos using scripts comprises:

• at least one server for the processing of the script and the orchestration and/or execution of all tasks for the creation of the complete instructional video using said script, which contains a means for converting the initial script provided by the user in the different scripts, configuration files and instructions for the other components of the system; means for creating and executing virtual machines (These virtual machines are software that simulates a computer system and can execute programs as if it were a real computer); software installation media for them; means for creating presentations and simulations; screen recording means for virtual machines; means for carrying out actions on the user interface of said virtual machines; means for converting text to speech; means for creating subtitles; means for creating avatars or video characters that carry out the instructional explanations: means for operations and editing of the recorded videos and any other multimedia element stored on the server to be able to create a complete instructional video; means to generate the digital signature of the created video; means for publishing said video on servers, websites for publishing and sharing videos, content management systems, external learning management systems and/or massive and open online course systems and/or storage media internal to store the instructional video and any of its constituent elements such as the script file, virtual machines, intermediate video files, audio files, meta information and others;

• at least one user terminal that comprises a desktop, mobile or Web computer application to edit changes, validate the syntax, configure and/or parameterize the command sequence and to launch and monitor the recording of the instructional video to be generated from said script file. This user may or may not be the author of the script;

• transmission means from the user terminal to the server of the script file, and from the server to the user terminal of the instructional video generated at the end of the process and the status updates of said process.

The method of the invention comprises the following steps:

• Creation of the script file for the generation of the instructional video by the author or authors in the terminal or in other computer systems;

• Access to a desktop, mobile or Web computer application on the user terminal to edit, validate, configure, parameterize, launch and monitor the recording of the instructional video to be made from the script file;

• Sending the script file to the server from the terminal by the user;

• Processing of the script file by the server to determine the steps to be performed and the options defined by the author regarding the instructional video, generating script files, configuration and instructions appropriate for the rest of the components and media of the system ;

• Creation on the server of the virtual machine or virtual machines where the recording of the instructional video will be made;

• Generation on the server of teaching materials such as presentations and simulations and any other digital content to be shown during the instructional video;

• Startup and execution by the server of the virtual machine or virtual machines created;

• Installation by the server of the necessary programs and resources in the virtual machine or machines to record the instructional video, including screen capture and recording tools and programs for automating actions in the user interface. This step includes the server copying any resources and digital content that are necessary in said virtual machines or indicating that they can be downloaded from another location;

• Starting the screen recording on the virtual machine and executing the actions contained in the script file, completing the video recording, and creating one or more files for the initial video of the instructional content;

• Execution by the server of the text-to-speech conversion for the instructional video and creation of one or more audio files for the instructional content and the rest of the elements;

• Production by the server of the caption and subtitle file(s) from the script file;

• Generation by the server of the secondary video channel or channels with avatars or video characters that carry out the instructive explanations;

• Provision or creation by the server of the rest of the files with the video fragments for the sequential and transversal elements required by the author to complete the instructional video;

• Provision by the server of the graphic file or files with the logos, watermarks and other distinctive signs of the author;

• Provision by the server of the audio file or files with background tune, narration and any other audio file necessary for the instructional video;

• Composition and union by the server of all the previously mentioned files in the complete instructional video according to the instructions of the script file, applying the required transitions;

• Addition by the server of the signature and authorship accreditation elements to the complete instructional video file;

• Sending the complete instructional video to the user terminal by the server; • Posting of the instructional video on servers, video publishing and sharing websites, content management systems, external learning management systems and/or massive open online course systems;

• Store the instructional video and any of its constituent elements and metadata in the internal storage server repository.

Therefore, the user receives on his terminal from the server the complete instructional video with all the explanations and actions indicated to be performed for the instructional content and all other elements and content required for the instructional video specified in the script file by author.

All of this is achieved thanks to the means that create the virtual machine or machines, the installation of the software and provision of resources, the generation of teaching materials, the beginning and end of the screen recording, the actions about the computer programs that occur on the virtual machine and the generation and/or provision of the other elements and content of the instructional video occur on the server. Furthermore, it is not necessary to install any specific software for recording screens or even the software on which the instructional video is made, it is only necessary to install the desktop, mobile or Web computer application to monitor and/or control the Recording of the instructional video to be generated from the script file.
