Introduction
Videolinq offers a cost-effective and efficient way to create AI-Based native and translated automated closed captioning from recorded media and edit the data to improve accuracy. The final version of the captions can be exported in the SubRip Subtitle (SRT) or WebVTT (VTT) format for further use as media-on-demand with closed captioning on any streaming platform. In addition, captions can be exported as transcripts in PDF format. Automated closed captioning is a fee-based service. This article explains how to create native or translated automated closed captioning, or transcripts from a pre-recorded file.
Upload Media
In the media dashboard click on the "Sources" "Content Management" and "Media Files" tabs. Use the "Upload a file" feature to import a pre-recorded file in the MP4 format. For fast processing, we recommend using a low-resolution/bitrate version file. For example, if your program is a 1080p 6 MBps file, 60 minutes long, prepare a 360p version file at 1 MBps, and upload it to create the captions or translation.
Create Captions
To create closed captioning from the native language in the recorded media, (1) point and click the checkbox of the uploaded file. (2) Drop down the "Language" option, and select the audio source language. (3) Confirm the "Translate" option is set to "None". To begin the caption creation task click "Start".
Wait until the closed captioning creation process alert disappears.
When the closed captioning creation process ends, check the checkbox, and click on the "Editor" button.
Inside the editor: A popup window will open. Here you can preview the video, search for specific words, edit captions, and add a line break to create a paragraph (to align transcripts better). Did you make a mistake? Click on the reset option to restore the original version. When ready, export the caption files in the SRT or VTT format. Export transcripts in PDF format.
Create Translations
To create a closed captioning translation from the native language of a clip do the following: Upload a media file as explained in the first step of this article. To use a file you uploaded already, (1) check the box, (2) release the previous captions file when applicable, (3) drop down the "Translate" drop-down option, and select a desired language to translate to. For example, let's select Spanish. Click "Start".

Click the pen icon, rename the file, and save.
Connect the Spanish captions to the video file by (1) clicking on the plus sign (2) drop-down to select the file you just renamed, and attach it.

Let's create another translation from the original media source (1) disassociate the previous caption file from the source media, (2) check the box of the media source, (3) select the next target language for translation.
Wait until the closed captioning creation process alert disappears.
Repeat the step to release the new captions file, rename it, and (1) associate it back with the media file from the (2) drop-down option.

Tips & Tricks

Use the preview player in the editor to jump into a specific time frame in the video. The corresponding caption lines will sync to the video.
Create a playlist from multiple media files and assign the playlist as the video source for the channel. Start the channel and enable automated closed captioning, The channel will use the content of the playlist as a video source, and add the automated closed captioning to the content.

Videolinq supports 60+ languages for the creation of captions & transcripts from files, but we can only add closed captioning to live streams in English, French, Spanish, Italian, German, and Portuguese. Keep this in mind if you plan to use files + captions as a single clip, or a playlist, as a video source for a live channel.
