.avi, .vob, or mpeg???

Discussion in 'MPEG-1 and MPEG-2 encoding (AVI to DVD)' started by Jazzyjazz, May 2, 2003.

    Good Day,
    I burn VCDs and SVCDs. I can rip the original dvd into either of the following formats: .avi, .vob, or mpeg. I use Nero to burn vcd or svcd and Nero makes the conversion to vcd or svcd automatically when I burn the disk.
    QUESTION:
    Is there an advantage to choosing one of the above formats over the other when ripping? By this I refer to image quality of the final burned vcd or svcd...will one format yield better image quality over the other? And which format will yield the best image for viewing on my computer (from the saved file stored on my hard drive)?
    Also, does either format rip at a faster rate than the others, ie; does it take longer to rip the same file to .vob than it does to rip it to .avi or mpeg?
    Finally, do programs like Nero treat these formats the same?...is the image quality the same in final product? Does Nero convert these formats to vcd or svcd at the same rate or does one format convert faster than the others?
    I realize this is a long post so if you answer only one portion, I will be most grateful.
    Respectfully,
    Jasper

    You get the best video quality burning DivX (MPEG4) but there are limited home dvd players that play DivX format. The next best format is SVCD (MPEG2) and many people use this format and there are many home dvd players out there that support svcd playback. My advice? Encode SVCD (MPEG2) and use CCE (Cinema Craft Encoder) using DVD2SVCD. Even if your home dvd player don't support SVCD, you can watch your backups on your pc until you purchase a "compatable" home dvd player that plays svcd format.

    Good Day,
    THANKYOU for your timely reply. Your response address the issue of the FINAL burned product, svcd. I read on the forum that svcd is higher resolution than vcd and that CVD is the best (but not as compatible with stand alone dvd players as vcd and svcd)...do you confirm this? Now, can you tell me which of the 3 formats lends itself the best to the creation of svcd?...meaning should I rip to .vob, .avi, or mpeg initially...does one of these formats create a better image (in svcd/vcd/cvd) than the other or show cleaner on my pc? Does one rip faster than the other to hard drive, then ultimately, convert to dvd format faster using software like Nero? This is the heart of my question...which format should I rip to (.vob, .avi, or mpeg) and why.
    Respectfully,

    Good Day,
    I found some goo info here...it's a pdf file:

    http://www.mediostream.com/pdf/MedioStream_Performance_Test_Report.pdf

    Page 3, 3rd paragraph, last sentence staes, "Typically, processing of DVD-compliant MPEG-2 or VOB files will be faster than processing files in other formats." I assume these "other formats" include .avi. These comments ref dvd cration and not svcd\vcd\cvd so I am not sure the results apply directly to my question...but this is the type of info that I am looking for.
