Why do rippers size down 720xXXX for in xvid dvd-rips even for 1400mb rip

[peaceDOThuxDOTde]

I want to make small but nice quality x264 rips. I can archive better quality with lower size then with xvid. and i am thinking about ripping to 720x480. But almost all rips xvid rips i see are sized down to 640xXXX i mean when they do a 2 CD rip why do they resize? for 1 CD i understand it because the size gets smaller but 2CD is this nessasary? The image gets blured if u crop it down like this. if this makes sense with xvid how about x264?

Why CD?

They crop to force fit.

Because "The Scene" is living in the past.

Ten years ago many Divx/DVD players wouldn't play Divx files wider than 640 or 720. But even on players that could play 720 pixel wide Divx they wouldn't play files greater than 480 lines tall and didn't support aspect ratio flags. So 4:3 material was encoded at 640x480. So 640 became the desired width. Players have come a long way since then. Even most Divx/DVD players can now play 720 pixel wide Divx files and respect AR flags. But The Scene doggedly sticks to their rules.

I encode all my DVD rips at the original frame size with x264 and AR flags.

crop was the wrong word. i mean resize the image. the dont crop existing image data i guess.

and thanks for that andwer. so its not because of size rediction its just for a total outdated compatiblity issue?

are u speaking about software or hardware players?

Yes. 640x480 is reasonable for 4:3 material if your player does't support AR flags.

are i speakign about software or hardware players?

Hardware players.

thanks for the help

i just saw 708(643)x480 and aspect ratio 0.909 in mkv to mp4. does this mean the video is streched to 702 anyway? pixel aspect ratio of 1:1 makes more sense to me. i guess i need to know the basics of 4:3 dvd ripping

i have this problem with this video btw

The DVD is probably 720x480 and the program is cropping away a small black border, leaving 708x480. When played the player should adjust the picture to produce a ~4:3 picture (708 * 0.909 = 643). That doesn't necessarily mean 643x480. An upscaling player will upscale to ~960x720 or 1440x1080.

Look for a setting in the software that lets you specify the modulus. Set it to 8 or 16. Then the software will give you a 704x480 (mod 16), 712x480 (mod 8), or 720x480 (mod 16) frame size.

Well i did rip it with mod4 intentinally because i think x264 dont need mod16 or 8.

are VLC and x264 not sitting in the same boat? strange that wmp with the default codecs shipping with win7 has no problem with this and VLC does have this bug
