H.264 default codec

I recently exported a video using H.264 Main Profile. The format says MP4. Under the Codec tab I selected “Default for format.” So my question is, what is the default codec for MP4 (H.264)?

Thanks,

Darin

Not sure I understand the question, but MP4 with H264 codec is the more widespread combo used.
It’s advised for Youtube for ex…

Yes, H.264 is the default video codec for MP4 for the libraries being used (FFmpeg).
