XVCDs in ffmpegX

[Tolly]

hey major, since ur the smart one with the great prog, lol , i gotta question for ya. does ffmpegx produce xvcd or xsvcd? because from what i understand there is a pretty big difference between the two. and the answer for that will help out another question, how do u figure out the correct size? correct me if im wrong, but isnt xvcd usually 352x240, and then xsvcd is usually either 720x480, 352x480, or 352x240? so which do i choose? any other special things i shoud know when using this this ffmpegx app for this purpose? and thanks alot, i appreciate all help u have provided for me and others!

Tolly, 0.0.2 only makes xvcds. btw 0.0.3 will also make xsvcds. xvcd can be 720x480 NTSC (720x576 PAL). Some DVD players handle also different sizes, you will have to try different clips with your player. Encode the same 1-minute clip in 20 different sizes and pack them with VCDToolsX in a single test XVCD

Major, how does your prog make XVCDs ? I thought that any DIVX encoding would show up poorly when you try to watch a XVCD on your DVD player ? (read poorly as "all white no picture"

Can you actually take a DVD to VOB then to XVCD with your program ?

If so, how ?

XVCD is MPEG-1 authored as .bin/.cue

ffmpegX can create it by first converting VOB (or DivX) to MPEG-1 and then packing the MPEG-1 file as .bin/.cue (so you can then burn the .bin file in Toast Video CD Mode).

Well, ffmpeg can convert DIRECTLY from DivX to MPEG-1 without using Quicktime. ffmpeg was/is a *nix app so the Quicktime libs weren't available. ffmpeg isn't too good about converting most Quicktime, including DivX embedded into Quicktime files using the official codec.

Anyways, I have converted DivX using ffmpeg, and with proper tweaking, the noise that remains is the noise already present in the DivX file before converting (I try to hover right around 1500kbit/384kbit for video/audio when using ffmpeg... I can get lower with TMPGEnc, but ffmpeg doesn't have quite as nice an engine)

Major, are you planning on adding a MEG-2 CODEC to the build ? SVCDs look great compared to a VCD. I don't think that the program can code for SVCD right now.

I'm including some useful new features in 0.0.3 which will allow to one-pass converting a VOB into 2 or 3 CD-R with very very nice image quality. It should be ready in about a week. I need much time to process all requests.

Major, will you need to burn in Toast Video CD mode or can you use VCD Tools and burn in XA Mode ?

One comment, maybe the default GOP size should be lowered in 0.0.3? 240 frames is way too high if you and everyone around me recommends 15-24.

[major]

GOP=240 is for DivX, 15 or 18 for MPEG1

[Krevinek]

The GOP shows up to me as 240, even though I changed the video encode over to MPEG-1... maybe a different bug than I expected?

[major]

enter the GOP size yourself by typing it into the field. 0.0.3 will include automatic settings.
