Video and audio hiccups w/ DVDx 2.0

[Memo_182]

I'm trying to encode a .vob file to vcd/svcd but my audio and video hiccups ie Audio hiccups/ video slows down and the speeds up. Please help. Thank you.

I have had occasional audio/video synch problems (the audio lags by about 1-2 secs) when using DVDX2 to convert .vobs to DivX. I get a "step-up/step-down" message before I start converting; but it only happens occasionally with seemingly random movies.. Do you get a similar message Memo?

Anybody have any ideas?

The step up and down is because you chose a framerate that is different than the movie. If you choose 29.97 and the movie is film 24 fps then it will do a 3:2 puldown (up).

The audio problem is inconstent. Sometimes clicking on audio synch makes it worst and sometimes not.

There is an explanation on the "read this first" under the "file menu" about a blank movie frame that causes synch problems in some movies.

You can always demux and remux the output I guess.

Yeah I get messages like that and after it finishes encoding i get "overflow/Underflow error messages" and it is also with random movies.

Good results can be achieved by using DVDx to rip and frameserve to tmpgenc. That way you don't need 5 gig on your HD and still let tmpgenc do all the encoding. It has a better mpeg1/(mpeg2 $48 ) encoder than DVDx and you can control the settings or use prebuilt templates. You get the best of both worlds that way. You can resize in DVDx or move the whole 720x480 to tmpgenc and do the resize there or frameserve using avisynth and make adjustments with the scripts.

thanks GL, but how would I go about doing all that then using tmpgenc and DVDx. Would I still get the same problems if I enconded into AVI and then use Tmpgenc to encode to MPG? or should I just try something else to rip my DVDs (with out using DVD2AVI, i didn't like the quality I got when I used it) Thanks.

Thanks GL.. I will try unchecking audio synch and see what that does..

I'm kind of a newbie to all this, what do you mean by demux and remux the output?

You don't encode to avi in dvdx. You use the frameserve "plugin" within DVDx output settings and then set the plugin to either use the avisynth (avs) or aviwrap (avi) but its just a placeholder it doesn't really create a video avi or avs it's just a file with 1 line (unless you add more for scripts).

You then start the copy in DVDx but instead of creating a file it opens the frameserver plugin and sits waiting for a call for data from tmpgenc (or any other calling app which uses these plugins).

You then open tmpgenc and tell it to open the avs or avi that you named in the DVDx plugin option and identify it to tmpgenc as though it is a video file. Just watch the file boxes to make sure it finds both the video and audio. You can adjust anything as usual or use preset templates in tmpgenc. Its all the same as a normal encode.

You set all your options in tmpgenc including the name and dir for the output file and then when ready press start encode in tmpgenc just like a normal encode.

If you watch the plugin window you will see audio and video is being fetched from DVDx and passed to tmpgenc just as though you had created an avs or avi file but in fact its just being passed from one program to the other via the frameserver plugin.

With the avs you can do more because you can edit the avs file before opening tmpgenc and add some scripts using filters which will be applied during the pass. That's a little more complex for now but good to know for the future

In tmpgenc on the file menu there is an option to select mpeg tools.

This allows you to demultiplex the audio and video which seaparates them and makes 2 independent files.

When you remultiplex them then you are rebuilding or remixing them together and it adjusts some pointers too. This often will repair simple synch issues.

If you only have a video and 1 audio track then you can use the simple demux and remux options.
