Fast DVD and too many frame drops

[Toche]

Hi Major,

I have try the new option "Fast DVD" but unsuccessfully because i have a "Too many frame drops" during the multiplex process. But if I create the DVD folder manually with the 2 files (.M2V & .AC3), it works.

Use 0.0.9d. It fixed lot of issues related to "fast" presets.

But with the same setting, i have a bigger .mpg file.
The first one 1500Mb and the second nearly 2000Mb.

My setting was Fast DVD preset and i've change 5:1 audio in Stereo.

If i drop the new .mpg file on ffmpegX icon and check with the info button, here are the results:
Muxrate: 8:45 Mbps
Audio: Mpeg 1 Layer 3 112 kbps 44100 Hz Stereo, No emphasis

With the old .mpg file (0.0.9c):
Muxrate: 10.08 Mbps
Audio: Mpeg 2 layer 2 48 kbps 24000 Hz Dual Channel Emphasis CCITT J 17


Is it normal?

BTW, you have change the Q min & Q max default setting?

Thanks Major,
Toche

Are you sure it was totally muxed, start to end? As it seem your first file had a mux error.

If i drop the new .mpg file on ffmpegX icon and check with the info button, here are the results:

Don't use the info button (I'll soon remove it), it's not as reliable as the info line which is shown above the Open.. field. Please post that information instead.

BTW, you have change the Q min & Q max default setting?

Yes.
