Hi,

Just reposting this, something is definetly wrong with this because I just burned the example svcd image from VCDHelp for Pal and it played on my standalone DVD player perfectly, but it doesnt matter what encoder I use or what setting I put the SVCD created from my DV footage all have th bottom half wabbling around after the top half (which is playing perfectly) What gives? Please help!!!

I tried your recommendation owelsroost but it doesnt change anything for me :(

Thanks though..

D.

OK, list out the project/'Render as'/MPEG settings and the process you're using to encode and author the discs - I'll try and spot the problem.

It is definately possible to make decent SVCD with VV3.

For reference, DV is always bottom field first interlaced, so the MPEG encoder should be set up the same.

please go to ftp://porker.sonicfoundry.com/

folder: Vegas 3.0b MPEG beta fix

drop all of the components in the folder named ":\Program Files\Sonic Foundry\Shared Plug-Ins\File Formats\MCMPEG" choose yes to overwrite all, and then restart Vegas and try another render.

Still seeing it?

It didnt fix it :( I have been able to create a progressive SVCD using TMPGenc by falsly stating the the video source is non-interlace and then removing the fields by blending. This created SVCD that works on my standalone. If I for example set the source as non-interlace and code it without field removal, I get a what looks like footage with invese field order, where the whole footage jumps like the top comes first then the bottom. If I set the footage to non-interlace but encode it as interlace I get the same half bottom junk, look like the top half is playing well but the bottom half is jumpign between fields / frames. With VV I was unable to get any of the settings to work :( which is not confortable because I have to do one extra encoding on my editied footage in order to transport it to SVCD :( Oh.. also.. if I do frame by frame view of the VV footage on my DVD player.. all the frames look intact.. as well as if I FForwards there appears to be no jumping, so it only occures when its play back, maybe its something to do with aspect ratio?

Ive posted my mpg file that I burned on my SCVD at:

http://www.geocities.com/malyavin/

the file is drdtest1.mpg


When I burned this file to the SVCD and tried playing it, it playes with the bottom half all messed up, the encoding was done as default SVCD Pal with the addition feature of write sequence display extensions checked. (it didnt make any difference with it unchecked ether)

Thanks,

BTW, the important change in my SVCD fix is in the 'Render As' dialog - tick the box 'Stretch video to fill output frame size (do not letterbox)'.

Which DVD player are you using?

If you post your email address, I'll send you some screen grabs of PAL SVCD settings (from PAL DV sources) that have worked for at least two people (and on two different DVD players).

Yes please send me the screen shots :) malyavin@yahoo.com

Just wondering does it matter what the actual project settings are? or does the Mainconcept plugin use the sources directly?

Ive tried it with the setting you recommended it still didnt work :( I did make a NTSC SVCD using the PAL footage (I just set it as NTCS SVCD on export) it played without any problems on my DVD, so there is something wrong with eather the aspect ratios or the fields for interlaced Pal video.. :(

The project settings should match the sources (for PAL DV - 720 x 576,
interlaced, bottom field first, 25 fps) - the size settings in the MPEG
plug-in handle the resizing from the 720 x 576 DV size down to the correct
480 x 576 SVCD size.

Also you need to use 'good' or 'best' rendering quality
when handling interlaced sources in VV3.

Screen grabs on their way....

Hi,

No success with your screen capture :( I guess my DVD player is no 100% SVCD complient :(

I think that's probably the case - I tried making an SVCD from your file, and apart from displaying the jitter problem that my settings should fix, it played OK on my DVD player (although Nero rejected the file as not SVCD compliant, Ulead DVD Movie Factory was happy with it, which is what I used to author the disc).

Was Nero happy with the file when you tried it?

You could try authoring with DVD Movie Factory (the trial version is fully functional for a limited period) - I'm not very hopeful it would make a difference, but you never know.....
