One good thing about 9.0d...

Recently, I've been rendering videos to the Mainconcept AVC/ACC codec for uploading on the web. And recently, I've been encoding higher resolution video at 1920x1080 into this format. Vegas Pro 9.0c produces video that has horrendous seek times when viewing them in WMP. These same videos produced with the exact same settings in Vegas 9.0d produce video that seeks beautifully in WMP.

Was an upgrade(or changes) made on the Mainconcept AVC/AAC codec?

I looked at the release notes for version 9.0d and didn't see any mention of changes made to this codec.

Just curious -- what do you mean by "seek" times in WMP?

If I'm watching the video in WMP from the beginning and I want to skip to the half way point of the video, the seek time is how long it takes before play continues from the new point I clicked on. Should be nearly instantaneous.... but it wasn't with 1920x1080 MP4 files generated with Vegas 9.0c.

Don't know about AVC/AAC, but I noticed avi files cue beautifully in WMP now.

Might be some "quiet" Vegas improvements, or some MS update patched the WMP...

it may be that the moov atom for the file is at the end, so the entire file has to dl before it begins to play. try running the mp4 through mp4 fast start. http://www.datagoround.com/lab/

if that doesn't do it, try handbrake. http://handbrake.fr/downloads.php keep the same settings the file already has.

From the release notes:

"Fixed the ability to seek in files rendered using the MainConcept AAC/AVC format. "

I suspect that addressed your problem.

I didn't see that in the release notes but discovered it on my own. No seek problems with Vegas 9.0d MP4 files... just slow veg load times and unusable Protitler media from old projects. :(

9d has a lot of good features but is a FAIL overall due to it's unusable Cineform performance (at least in Windows 7 64 bit). Hopefully there will be a 7e that is actually useable and not just an 8a with a whole new set of problems and issues.

Given the recent trend, a cynic might say that the best thing about 9.0d is that it's not 9.0e. :-)

How do you get MP4s to play in WMP?

I didn't realize that WMP couldn't play MP4s in default Windows 7. I've installed Shark007 Windows 7 codec pack... maybe that installed a codec that enables WMP to play MP4s...

Sorry, don't understand how WMP uses codecs well enough.

Yeah I have that same codec pack, and it works in Vegas, but not WMP. Weird, maybe I have to point WMP to the codec? Does anyone know how to do that?

Thanks
