Likely, either of these custom render templates will be adequate for "preview" and meet the letter of the spec.

Handbrake may deliver better results at the bit rate (5 mbps). You didn't state the frame rate. I'm assuming NTSC.

When version of Vegas? If you have VP15, you have the additional choice of MAGIX AVC, which includes an updated MainConcept codec, presumably with higher quality per bit, as well as QSV & NVENC encode modes.

yes I have V15, but i didn't think it h.264 They are not looking for higher quality as this is a "preview" version....their is another set to follow for the broadcast video.

Thanks

5Mbs or 50Mbs ? 5Mbs seems really low for 1080p. Even Youtube gives it 3 more Mbs.

5mbs...remember this is the preview version they are requesting..to scrub thru it.

See Wikipedia reference.

"The ITU-T H.264 standard and the ISO/IEC MPEG-4 AVC standard (formally, ISO/IEC 14496-10 – MPEG-4 Part 10, Advanced Video Coding) are jointly maintained so that they have identical technical content."

The AVC encoders in Vegas are h264.

Excuse my ignorance....when I select Sony AVC to render, then use mediainfo, I don't see h.264..but AVC codec:

I guess that is what we are saying, that it's the same thing?

ID :2

Format :AVC

Format/Info :Advanced Video Codec

Format profile :High@L4

Format settings :CABAC / 2 Ref Frames

Format settings, CABAC :Yes

Format settings, RefFrames :2 frames

Format settings, GOP :M=2, N=15

Codec ID :avc1

Codec ID/Info :Advanced Video Coding

Yes. H.264 and AVC are interchangeable terms.

A little off topic but still related to TV. If you haven't already is to record colour bars and tone in the beginning of your 30 minute segment for at least a minute. The engineer at the TV station can see via the waveform monitor if their system is lined up before viewing your segment.

Yes AVC and h264 are one and the same, like coriander and cilantro!
