I know this has been a thread before but I didn't really find a solid answer from anywhere. I have tried several different things for exporting to H264, but they all end up looking brighter, and I don't know how to fix it.



Vegas to sorensen 3 uncompressed (looks fine) then in qtp I export as an h264 with no filters but it still gets brighter. I checked my videocard settings in the nvidia control panel and turned off all settings to change anything for the video.

I also exported from vegas to the frameserver network client thing as an avi which goes to TMPG and renders as a h264 mov. If you don't know what I'm talking about it is found here. http://www.dvxuser.com/V6/showthread.php?t=85443

Please help me out!!

Thanks.
 
Ok so the RAW Uncompressed AVI is here.

I bumped the Alpha Gain to 5 on this one.

And trust me it looks alot better than the standard settings.

Here is the Saturation at 150 vice 100

To me the Saturation really helps alot, makes the colors pop better.

Heres the link to the H264 cropped to 235 with the 150 saturation on it.

The linked file looks a lot better than the single frames you have posted here. I tried Googling the h264 PC issue and it looks like it might just be "unsolvable". There's not much in the way of helpful information, aside from outputting the base avi with heavy compensating CC on it (crushing it way down and then letting h264 brighten it, but I'm not sure how well that will work). That just sucks!

Get a Mac.






Hahahahahahaha!
 
IF, i think the only reason that the video looks beeter is because I have transferred the screencaps a couple times over the internet and the between programs. But the difference is still there. The orange in the first plate is very apparent.

Working on the mac.....give me a week :D
 
So basically for now the only fix is to guesstimate how much to compensate the brightness?
 
I dont think its actually the brightness of it but the de-saturization of the final product. More results will be up tonight
 
(I'm assuming your on a PC)

Export your video file to something that will play in windows media player. Highest quality, forget file size.

Download a program called MEGUI

Use the ce-quicktime profile and compress h.264 files into .mp4 that look better than quicktime.

Be glad that it didn't cost you a thing other than your time.
