There should be a bug in the CQ_VBR mode because :
1/ a 70 minute video at 352*240 fit easily on a CD WHATEVER THE QUALITY.
I mean that at this resolution you can put 2h30 on a CD in CQ mode at CQ70 and 70 minutes can be done at CQ=90 and you will sitll have space on the CQ (100 or 200 MB free may be)
and
2/ CQ=70 is equivalent (in words of quality) to CQ_VBR=18. CQ=80 -> CQ_VBR=22. So normaly, above CQ_VBR=25 you should reach the maximum quality.
But here, as even with CQ_VBR > 25 you don't fit the entire CD, the program still continue to try higher value. And there ios where the bug occurs : it seems that a CQ_VBR of 89 gives you an horrible result
It's like if this mode was never designed to be used with values above, let say, 30. You understand me ?
What you have to do :
1/ try the exact same video with a resolution of 544*480. Just for testing the tool. You will see how that it works very well.
Or try a longer video (1h45 - 2h). Or why not, try that video but with a target size of 400 MB insteed of all the CD.
or
2/ encode the video at 352*240 and CQ_VBR=25 and you will see that what I explained to you just above is true.
Edit: I just saw that line in your log :
Code:
Average Bitrate: 1394_anamorphic=false)
It is very stange, as you can guess.
I never saw if I have the same in my logs...
