The SDL should be optional (but if you want to run yuvplay I think the SDL becomes required - so it is just as well that you have it installed now). > Still had the quote warnings though from the other packages but it > didn't stop it.

Then used the same I do not believe that 'cat'ing mpeg files together is the correct thing to do.Better method would be to replicate the source frames and feed a large stream of input into mpeg2enc. Instead of creating 6 second clips and replicating 10 times it may be necessary to create a single 60 second movie. > Created an xml file for just a simple DVD, no menus or anything.

While there are several video sizes that can be used the audio has to be at 48000. I don't think that's the the problem in this case though. > If this is a dvdauthor type of problem and everything is OK with mjepgtools, > then I will post there. At this point it looks like a dvdauthor issue. I'm not sure how to create a slideshow with dvdauthor - but if it's possible then dvdauthor probably has rules/guidelines on how to do it. Perhaps creating mpeg still images and crafting some xml to say how long to display each image, etc. Looks as if the mjpegtools-cvs configuration battle has ended in victory though - and thats good!

I understand SVCD is similar to XCD which needs the Riff CD/XA filter. I set this up yesterday on Win98 and it works fine for XCDs with Zoom Player.

So, if size doesn't matter is it _always_ better to use tmpgenc, also with _bad_ sources? I mean, when I encode an old VHS-movie with poor quality, could the result be _better_ with kvcd or does kvcd safe space only? Al --- This SF.net email is sponsored by: Perforce Software.

However, depending on if the m1v has sequence end markers in it mplex may be prone to attempting to split the multiplexed result at the joins. There should be absolutely no problem with audio (unless you changed encoding paramters mid-stream, but even then it *should* work just fine). How did the audio go wrong: any error messages? Andrew PS If the source of the .mp2 is a demultiplex 'rip' from a Digital TV or SVCD/DVD/VCD stream you may have difficulties. The audio frames don't align with the program stream packets which would mean the last one of each rip may be cut-off in the middle. --- This SF.net email is sponsored by: Perforce Software.

Well, if size doesn't matter you can use '-K hi-res' :-) What I use for high quality encoding is a custom table made up of the hi-res Intra matrix with the tmpgenc nonIntra matrix and then -K file=myfile > I mean, when I encode an old VHS-movie with poor quality, could the > result be _better_ with kvcd or does kvcd save space only? kvcd's claims to fame are 1) smaller filesizes (lower bitrate) and 2) reduced splotchiness (pixelization I think is the term used) during dark scenes. The kvcd folks never made any claims about increased quality. For old VHS movies that have been run thru yuvdenoise and/or the medianfilter the use of kvcd tables won't really hurt the picture too much more. A good reason to use the kvcd tables in this situation would be to reduce the blocks/splotches during dark scenes. Experimentation is an important part of the process - try it and see what happens.
