View Full Version : CCE VBR max rate missreading

Im fairly new to using CCE Trial, but Im pretty sure Ive done everything correct, its not all that hard once you mess around for a while and read the guides and forums.

That being said, I made an mpv from an avi using VBR with multiple passes setting the minimum to 0, average to 3100, and max to 8000. I used 8000 because the final dvd will have two audio tracks and a subtitle track so I wanted to make sure to have plenty of headroom.

Now when I import the video to multiple programs, they recognize it just fine except that they think its max VBR is 9,800 so they wont compile the dvd with the extra tracks.

I suppose I could do a CBR encode to get around this, but it should work correctly, I dont know why CCE is putting something in the mpv that makes these programs think that it is 9800 when I made it with 8000.

Please someone help me figure out whats going wrong here.

Hi,

Just a thought. Is DVD-Compliant checked in your template? If so, try it unchecked. I have read here previously, that checking DVD-Compliant ignores your specified maximum bitrate and sets it to approx 9800.

Regards,
Bob

Thanks for the quick response, yes DVD compliant was checked during the encoding. Does that do anything else that might cause the videos to not work once compiled?

I just always assumed that if I was making mpegs for dvd use they should be dvd compliant :p

I will recode my mpegs and see if that works. Thanks again for the help.

I finally got a chance to recode today, and it worked just like it should with that flag removed, thanks.

Checking "DVD compliant" does nothing more than writing 9800 for the max. bitrate to the GOP headers (just an info, so to say, see CCE manual), but CCE still respects your true max. bitrate settings. Now obviously your authoring program mistakes the GOP header info for the actual max. bitrate. Scenarist and Maestro don't have a problem with this BTW, they start muxing right away and barf only when the total muxrate gets really too high.
