Problems winth virtual dub.

I want to put subtilities to a movie but virtual dub say "warning: nothing to output bframe decoder lag". I get the ac3acm but I dont know how to use it.

 

What does ac3acm have to do with subtitles?
You should have a .srt file.
Open the video in virtualdub, select filters, add, subtitle, browse for the subs file, and then re-encode or frameserve.

 

yes. I do that. But the problem is that in the tmpgenc does'n start the sound. And when I lunch virtual dub apear a message there "warning: nothing to output bframe decoder log". I think that because the sound is ac3 type. And in tmpgenc doesn't apear nothing in the "audio surce" when I want to put the subtitles into movie.

 

Tmpgenc cannot do AC3 (no matter what).
Rip the audio to .wav in virtualdubmod first, then use that .wav as the audio source.

 

Ok. It works. Thank you. I ascked because I read from one subject on the forum that the ac3acm is an update or something witch alow you o rip and ac3 winth virtual dub. Thank you for the help. I need't so badly.

 

Yes, that's exactly what the acm does. It allows you to rip the ac3 from a file (demux) or alternatively convert it to .wav for tmpgenc, using virtualdub(mod).

 

So you tell me that I couldn't get the wav winth virtual dub if I hadn't that ac3acm?

 

Exactly.

 

TMPGEnc also uses ACM decompressors though.

As for the bframe lag bit. Simply due to the fact that your avi uses bframes that are not packed. It has nothing to do with AC3 or subs, simply a limitation of the VfW framework (1 frame in, 1 frame out).

If you are wanting to hard encode subs using TMPGEnc, you could set ffdshow to decode XviD, enable subtitle support, crank the dshow priority in TMPGEnc and then just encode.
