Question

Premier Pro 14.3 export h.264 moov atom location?

Hi,

 

I found some forum posts that say Adobe Media Encoder puts the moov atom at the beginning of an h.264 export.  If I export from within Premire Pro is the moov atom also at the front? 

 

Thanks

    I would very much expect that it is. This is an interesting question as this issue came up a long long time ago for encoding for live streams and Adobe Media Server had to write MOOV atoms in the right spot or streaming would fail and all kinds of issues came up. As such, I believe Adobe learnt a lot from all that and then YouTube carried that forth to how they do their streaming now too. It's an important thing to be honest and I would expect that there isn't any software out there that puts it in a different spot.

      • I want the moov atom file to be written to the beginning of the h.264 file.  I am not sure if exporting from premiere pro does this.  The video file will stream while buffering.  As opposed to waiting for the file to download if the moov atom data is written to the end of the h 264 file.   On streaming platforms.

        I've been on this forum and others ... including pro video post forums ... for years.

         

        Yours is the first post I've ever seen mentioning the moov/movie atom. I had to go look it up. And there aren't a lot of posts from any pro source about it.

         

        I'm a contributing author for a pro colorist's teaching website, I produce tutorials for that site. It's never come up, and of course, everything for that site will be seen over the net. And they are incredibly tech and format/codec savvy. Including being the team that recorded DolbyVision's in-house video tutorials on working in DolbyVision for Netflix and other streaming services.

         

        If it was something they had any interest in, I'd have heard about it.
