Convert SVCD to DVD
There are a few problems with this approach. SVCDs resolution are most commonly 480x480 or 480x576. This is an invalid horizontal resolution for DVDs. The audio is also 44.1kHz sample rate which is also invalid for DVDs If you have a really cheap and nasty DVD player which doesn't care about standards, this type of invalid disk will (probably) play perfectly well. However I would recommend using ffmpeg to scale and reconvert the video and audio. example would be; ffmpeg -i svcd.mpg -s 720x576 -vcodec mpeg2video -b 9500 -maxrate 9500 -bufsize 230 -f mpeg1video -aspect 16:9 -hq dvd.m2v
replace 576 with 480 for NTSC, and then the audio ffmpeg -i svcd.mpg -ar 48000 -ab 224 dvd.ac3
then you need to mux the resulting files. mplex -f 8 -V -o dvd.mpg dvd.m2v dvd.ac3
The mpgtx step should be replaced with the really wonderful command line tool dvdauthor, which can be built for MacOSX. It will join the mpegs as chapters and make the correct VMG and VTS IFO files. try; dvdauthor -t -o dvd_directory mpeg1.mpg mpeg2.mpg ...
then dvdauthor -T -o dvd_directory
This will create a DVD directory structure with the VIDEO_TS and AUDIO_TS directories which you can throw into your dvd burning software. I use mkisofs and the apple hdiutil to burn the DVD but anything will work. I can't remember where I collected all these tools from but I know that they all work fine on OSX. Mark |
