An H.264 encoded file suitable for both podcasting and streaming
Hi All,
H.264 / Podcast newbie here so this might either be real basic or real “undoable”.
First, if I understand correctly, H.264 is the codec and it can be “wrapped” in either an mp4, an m4v or a mov file. Is this correct?
Second, I have a bunch of 2-5 minute talking head video interviews to put up on a web page. Is there a preferred “wrapper” for streaming? Is there one for podcasting? And is there a format that would serve both purposes equally well? A format I could compress once and have the file be either viewed directly from a web page or available as a podcast.
Hope this makes sense, thanks in advance for any insights or advice you may have,
Marc

I’d say go for .mp4 – that’ll work in the broadest variety of devices.
However, there really isn’t a good hybrid for streaming/podcasting, since podcasting should be VBR and streaming CBR. Also, a streaming .mov/.mp4 needs hint tracks, which increase the file size for downloads. So, better to do two different encodes for the two scenarios. Also, podcasts tend to be at too high a data rate for streaming.

Hi Ben,
I had forseen the hint track difference but the VBR/CBR and data rate differences definitely point to 2 separate encodes.
Thanks,
Marc
