Is MPEG-4 in Quicktime .mov H. 264

[charles martin] “If I want to render out a Quicktime .mov file using H. 264 encoder will i achieve that if I select ‘MPEG-4’ in the video format dropdown in Quicktime when I render?”

No. MPEG4 is a broad specification and this option will not give you H.264.

[charles martin] “if not H. 264 when you choose the MPEG-4 then what is it?”

I believe it’s H.263 which is MPEG-4 Part 2. H.264 is MPEG-4 Part 10. Both are MPEG-4 but are very different.

You can’t render Quicktime H.264 with Vegas. You need to buy Quicktime Pro to do this and it would be a stand-alone render (i.e., you render uncompressed MOV out of Vegas and then convert it to H.264 MOV in Quicktime Pro)

You can render AVC/H.264 using the Sony AVC or MainConcept AVC encoders but they obviously won’t be Quicktime files.

If you use the AVC in Sony or Mainconcept, can you just change the file extension to be .mov as a possible workaround?

Thanks for these answers…much appreciated.
In the end it will be fine for my need.
The Sony AVC which creates an .mp4 does use the H.264 as you point out and it seems to achieve what I and the client need.
I will test out changing the file extension..but don’t think i will need to.

Nope. Not really.

But if you render AVC to an MPEG-4 container, nearly every .mov reader will support it. You should try this. The reason is simple: Apple’s Quicktime (eg, .mov files) was the basis for the MPEG-4 container structure. They’re not identical, but given that “.mp4” files are now an established industry standard, and it’s practically trivial to make a Quicktime reader support MPEG-4, it’s the right thing. Apple’s own Quicktime player, for example, supports .mp4 files.

I’m editing MPEG-4 AVC/H.264 (MOV) video files and am having a tough time. Does Vegas 10 have the codec for this. What should I render too after editing. I want to make dvds and upload to youtube.
Trouble is after I edit and render I wind up with missing video. Black spaces in the rendered video. It doesn’t seem to matter which format I render too. And the black spaces are random, different clips at different renders. Almost never the same clip. I may get a good 20 min. video 1 of 8 tries. Been work at fixing this for weeks. Upgrade the computer from i3 and new video card.
I’m using Window 7 64bit, Vegas 10 64bit i7, 8 gig ram, quadro 2000, solid state harddrive, and the latest quicktime.
