  1. I understand the whole process of creating a (S)VCD-DVD.

    But I am missing a couple of points and just want to clarify the following...

    The initial patch when demuxing is to fool the authoring program into thinking that it is a DVD compliant file. That I understand, but the patching of the VOB files is what I am missing. Why is this done? So that the DVD player recognizes it? Is this only DVD player dependant? Or must it be done for everything?

    What exactly are the different patch resolutions for?

    In Maestro I noticed that if I do not patch a VCD file and demux and author, it plays with winDVD. Does this mean that it will play in my DVD player that is able to play VCD's?

    Thanks!

  2. Machine,

    There is no reason to do any resolution patching for a VCD source.

    Resolution patching only applies to SVCD sources. The SVCD video resolution (MPEG-2 480x480 for NTSC) is not DVD standards compliant. VCD resolution (MPEG-1 352x240 for NTSC) is DVD compliant video. In the case of a VCD source (S)VCD2DVDMPG is mainly used for automating the process needed to change the audio to conform to the DVD standard.

    The reason you might patch when processing a SVCD source is because some DVD authoring applications such as DVDMaestro will complain and not accept the SVCD video file since it's a non-standard DVD resolution video. So you patch the video to "fool" the authoring application (DVDMaestro) into accepting the file and then you re-patch it later to the original SVCD horizontal resolution (480) when it becomes a VOB file so the your DVD player (if it supports DVD-SVCDs) will play the DVD properly.

    The patch resolution settings (resolution and whether to patch the 1st header or entire file) are dependent on the authoring application you use.

    Refer to this forum post for a listing of known application settings:

    If you use (S)VCD2DVDMPG+ to author your DVD-SVCDs then you don't need to do any patching.

  3. just so you know maestro does reencode the vcd input is gets. SVCD i don't know never done that.

  4. I don't think Maestro has any video re-encoding capabilties. If your video is non dvd compliant Maestro simply rejects it from being added to the asset bin. Can anyone prove/disprove this?

    Maestro mangles the video in various ways. I don't think it "re-encodes" it, but it sure does corrupt it on occasion.
