- Video with audio content significant to it must have captions in the original language. We accept the VTT format for captions.
- For a video named "video.mp4" in english, its original language captions should be in the same folder named "video--original-language--eng.vtt". "eng" in this example is an ISO639-1 language code.
- Audio with significant language content should have a transcript.
