SVCD Help

[Haku]

Ok a little help please.

when converting to svcd,under motion search precision what should i have it set on.

normal
high
highest
motion estimate search.

its set to motion estimate search when selecting a svcd template.

Also i know to get the best quality u should select a 2-pass VBR.But whats the other options also ive readed about 4+ pass'...whats would having more pass' do ???????

If you have alot of time select highest but if you select normal you probably won't see a huge difference. You might try to encode a 30 second clip with different settings to try them out.

TMPGenc will only do 2 pass and that should be used for quality encodings. Expensive encoders like CCE do many passes - some people say more than 4 or 5 you will see no difference but I leave that to the truly picky to decide.

Isn't a CBR of the maximum allowed SVCD bitrate better than a 2-pass VBR? Not knowing the technical ins and outs of MPEG encoding, that seems logical to me, but the response here has has suggested otherwise. Can anyone enlighten me?

Haku, for motion search accuracy...high quality (slow) seems to give the best bang for the buck (best quality for time)....highest quality (slowest) doesn't noticeably improve quality, but will increase encode time by alot..i think at least couple hours, depending on the power of your CPU...

2 pass VBR gives you best quality if you want to limit filesize....filesize can be estimated the best using 2 pass VBR...also giving best quality...

CMacleod, CBR basically sucks...reminant of the VCD 2.0 days....CBR is least efficient when it comes to bitrate allocation. yes, CBR at the max bitrate will give highest quality, but the filesize will be bigger. the better comparison would be if a rip encoded in CBR or VBR would have to be the same size, VBR will have better quality since VBR takes extra bitrate not needed during slow scenes and allocates them to high action scenes that need lots of bitrate (CBR gives every scene the same bitrate)
