640 by 304???

[juliencomputer]

i downloaded the matrix.avi and it says the resolution is 640 by 304. What should i change it into a vcd, svcd, xvcd, or xsvcd? its also 23.976fps. so if somebody could tell me what do do that would be great! and by the way dont tell me to check on the vcdhelp websit cause i already did.

thanks for answering,
julien

You can change the don't have to change the resolution, but you do need to apply pulldown to convert the 23.976fps -> 29.97fps.

To make life easier just load the NTSC_Film template (VCD or SVD) and encode. For a DivX soure I could recommend VCD.

Q: Is the DivX letter boxed? If so becareful w/ any resize as this can really screw up the picture. ie. might be easier not to resize it.

this is what it loooks like:

The Matrix [DivX]

i dont know what letter boxed is so this is what it was called when i downloaded it.

i want this movie to look as good as it does on the .avi format so are you sure its just vcd?

thanks for the post and please reply

Sorry this is so long, I'm giving back ground info and trying to answer you question

Letterboxing means that there are black bars and the top and bottom of the video. This is often done because most movies are short with a display aspect ratio (DAR) of 16:9, while TVs have a DAR of 4:3. To keep the 16:9 aspect ratio on a 4:3 display, they fill the top and bottom of the video with black bars (otherwise you have to cut off the edges of the film).

VCD vs. SVCD (or xVCD/xSVCD for that matter). At the same bitrate and resolution MPEG1 (VCD) and MPEG2 (SVCD)have the same quaility. The SVCD standard is higher than the VCD standard, but if you make an xVCD useing the SVCD bitrate/resolution you'll get the same quaility encode.

Anyway, the VCD standard is:
352x240 @ 1150kbit/s (video)
SVCD stanadard is:
480x480 @ 2520kbit/s (video)
both have audio at 44.1k @ 224kbit/s

You're DivX rip doesn't match either standard resolution. To make a standard VCD/SVCD you'll have to resize it. Or make an x(S)VCD at a non-standard resolution.

You can't make an encode that's better than the original source, so going from 304 -> 480 won't really help and 'could' hurt it. (604x304 makes no sense as an encode btw).

In theory thou 604x304 should be playable on a TV (resolution can be divided by 16). The quaility of the encode depends on the bitrate you use. The higher the bitrate the better. But most DVD players have a max bitrate of ~2880kbit/s total. That's about 39min per 80min CDR. Forget how long the Matrix is but that's like 3-4 discs? Or you can use less than maximum bitrate and get more movie on each CDR. At the standard bitrate for VCD an 80min CDR will hold 80min of video.

So best quaility is kind of hard to say, you need to decide what's best for you. All DivX converted source will not look as good as on the PC (DVD rips thou can look as good as the DVD). So it's a # of discs, time, personal choice thing...

Thank you so much! you are the first person to help me on this issue. thanks for taking the time to do this.
