Do I need to extract the audio from an MP4 before transcribing it?
No. Because MP4 is a container that holds both video and audio streams, the audio track can be read directly from the file, so you can upload the video as is.
Why does my MP4 file play video but no sound?
The file may contain a video stream with no audio track, or its audio may use a codec your player does not support. Checking the file's stream details in a tool like VLC or re-exporting it with an AAC audio track usually resolves the issue.
