Frameserving with vdub and cinema craft

[AD421]

why does frame serving with virtual dub always give me an audio sync problem after encoding with cinema craft? the movie starts out fine but near the end the audio goes out of sync. Is there any way to encode with cinema craft then burn it to an svcd because cinema craft doesn't do resizing.

If you have the disk space do this:

1) Set all video & audio processing in Vdub to do resize or what ever else you are doing.

2) DON'T FRAMESERVE, instead save movie in ~20min chunks with PICVIDEO set to 20 as compression, choose old avi format. This should give you roughly 2gb chunks. Be sure to name the chunks something like:

part_1.avi
part_2.avi
.
.
.
part_n.avi

3) Open part_1.avi in CCE and set parameters, while in the main settings window, press [video inputs]??? button. Then select the rest of the movie chunks.

Now CCE will encode all pieces into (1) new mpeg2 SVCD file. You can even do multipass VBR.

I do this sometime when I capture a VHS TAPE and create an SVCD.

This works and result is really good.

hmm i tried the picvideo codec but when i saved the avi, it was like 3000 mb.

There are three options you can try;

OPTION 1:
1. Separate the audio using VirtualDub to create a WAV file.
2. Frameserve the file to CCE but in the 'Input File' settings tick the 'Input audio from another source' and select the 'WAV' file created in step 1.

OPTION 2:
1. Separate the audio using VirtualDub to create a WAV file.
2. Convert the audio to MP2 using a product like 'BeSweet'.
3. Frameserve the AVI to CCE and create your SVCD in the usual way.
4. Use TMPGenc 'MPEG Tools' to multiplex the Video stream from the SVCD file but take the Audio streaam from the MP2 file.

OPTION 3:
Use the DVD2SVCD package to encode the AVI (This set of tools always processes the audio separately and usually overcomes any sync problems.)

kool thanks alot. i'll try the option 1 since i've tried the option 2 n it still gave me an audio sync prob. How long does it usually take dvd2svcd to encode a 3 hour movie? would the encoding time be the same as frame serving?

[bunyip]

DVD2AVI overall takes about the same time as manually frameserving, it uses AVISYNTH to frameserve to CCE 2.5 (you'll need this), It processes in three steps first it extracts and encodes the audio stream, then frameserves the video stream to CCE and third multiplexes the audio & video.

kool i'll try it. I have cce 2.50 but howcome in cce 2.66 it tells me in the video setting that super video cd and video cd is not available.

CCE requires that the video is already at the correct resolution for VCD or SVCD. This is why you will nearly always need to frameserve an AVI to CCE, so that frameserver will firstly re-size the video before it hits CCE.

If the resultion is compliant then CCE will enable the VCD/SVCD options.

Try a test frameserve using VirtualDub - with the re-size filter enabled and the size set to 480x480 (NTSC) or 480X576(PAL) and you'll see that the SVCD option is now enabled in CCE.

[AD421]

wow thnx! but is there anyway around frameserving to cce?

[bunyip]

Not if you want to do VCD or SVCD since it doesn't have internal re-sizing.
It will do plain MPEG2 but at the same resolution as the AVI source.

If you can capture at one of the compliant sizes then yes you can by-pass the frameserving.

VirtualDub allows setting a custom capture size - even if your capture card doesn't support it.

[AD421]

oh ok. Is there any other programs like virtual dub for frame serving to cce?

[bunyip]

AVISYNTH is the other well-supported frameserver, but it is script-based and requires a little learning.

This is the one that DVD2SVCD uses but you can also use it on its own.

I suggest you trial DVD2SVCD first since it does all the hard work for you, after that you can try experimenting with AVISYNTH on its own yourself.

ok thanks alot!
