This article explains the components involved in video uploads and how to add different language streams to a single video file.
The video file being uploaded is a container that consists of several components:
Codecs are algorithms used to compress video or audio streams.
Please consult this article for video and audio codecs that we support. |
As indicated by the diagram above, containers also contain different media types, such as video and audio, as well as captions and metadata about the file.
Therefore, the term "file format" refers to the container format, which determines the file extension for normal video files, such as .avi
, .mp4
, .mkv
.
The videos you upload will have one video and audio track, known as "streams."
You can have a video file with multiple audio streams or a video file with captions in different languages (subtitles) or video descriptions (closed captioning for accessibility).
If you want to upload
Refer to your video editing software manual or tutorial for information on using multiple audio codecs and subtitles or video descriptions.
We support languages and language codes that adhere to the ISO 639-2 standard. You can find a complete list here.
