    Can CloneDVD Mobile be used to create VCDs/SVCDs? I want to export some of my kids' movies to a CR-R for the grand-parents' car movie studio...

    P.S.
    BTW, what is the use of the VOB file passthrough?

    i suppose you could create an AVI file then burn it to VCD/SVCD using appropriate software

    if i remember rightly a similar thing was mentioned on another thread-what VOB file passthrough does (i think) is create one DVD type file instead of a load of VOB files that you'd normally get on a dvd and it can create VOB files which aren't limited in size to 1GB.
    anyone feel free to correct me if i got any info wrong;)

    Yeah, its then 2 conversions. One additional step to lose quality. Not good enough.

    A VCD is MPEG-1 and a SVCD is MPEG-2. Could'nt there be another generic output format (aside from DivX) to cater for this?

    SVCDs are ideal for car-mounted video systems. Wouldn't this be a viable mobile use?

    compared to dvd,vcd (in particular) and scvd quality is ok at best.you obviously want to burn to cd rather than dvd so the fact you mention ''One additional step to lose quality'' is irrelevant as you have lost dvd quality already by using clonedvdmobile.also,most video systems in cars wouldn't have that big a screen size anyway (7'' i've seen).with it being a small screen you surely wont notice the lower picture quality.

    a product that will do what you want to do-convert dvd to vcd/svcd-is this:

    You are right that car video systems generally use small screens. Thus, SVCDs are a very good format for those situations.

    But you are somewhat wrong about image quality. Going from the original VOB to a SVCD will always yield a superior quality than VOB to AVI to SVCD. The repeated use of compression/conversion algorithms compound quality loss. Using the highest quality AVI available might make the loss unnoticable but it would still be there.

    Moreover, you run a higher risk of introducing artefacts which are quite visible.

    Hi.

    Here are profiles to add VCD and SVCD (NTSC and PAL) output to CloneDVD mobile, just append them to your "Devices.ini" in the program folder. They have not been tested extensively yet, feedback is welcome.

    Greetings,
    Joe
