just out of curiosity.... why do you choose to capture instead of rip the movies, and encode after that? i dont have a capture card so i have never messed with that... but ive heard before on the forums that rips are way better quality than captures... or are you just capturing on movies you cant rip??

He's probably talking about capturing from cable. Now how can you rip that?
You are thinking only of DVD.

[DiViNeLeFT]

yeah, thats what i figured...

it is true that rips are better than captures though if the dvd is available, correct?

yep, DVD is a clean source, wheras TV or VHS because its trasnferred via an analogue method, picks up noise. could be your MPEG2 encoder is trying to ecreate this, and your DivX codec ignores it.....? incidentally, of course you can set an MPEG stream to only I frames, assuming of course your bitrate permits it/still looks good.

And on the higher compression = higher bitrate debate, well this would be true if DivX was lossless compression. there's two types see, lossing, and non-lossing. non-lossing formats are things like ZIP files. when unzipped, they 100% recreate the original file. lossing compression (i.e. MPEG, MP3, DivX, minidisc players, digital telly) throws away as much information as possible, and upon decoding, tries to recreate a file/image as close to the original as possible. therefore, a 10mbps DVD stream compressed to a 2.5mbps SVCD stream, will look lots better, than an 890kbps DivX stream. it's all about how efficiently you can throw stuff away before it becomes obvious youve done so........

This is a Bushleeg discussion!!

The man is talking about DivX to VCD or SVCD conversion. When we download movies illegal from the net, the most/only? available format is DivX. Now we would all like to be able to download movies and play them in a normal DVD player. This is not possible hence the need to convert to VCD or SVCD. Only the quality is crap! I have never seen a nice DVD -> DivX -> Mpeg1 or Mpeg2 result!!

Yes you can make nice SVCD's if you rip your own DVD's and yes this usually looks at least as nice as Divx, but this is not the issue. The issue is downloading movies from internet and play them in stand-alone DVD Players!

GET IT?

Before this gets out of hand (if it hasn't already), comparing DivX to S/VCD is somewhat like comparing apples to oranges. They have completely different functions and these should be recognised.

I believe that a well made DivX DVD rip can look better than a well made SVCD DVD rip -- but this is taking to account that a DivX file has not standards at all. It can be any framesize and and framerate. This sort of flexibility comes at a cost though.

The above example is only true on a PC. I doubt VERY MUCH you could get a DivX to look as good as a SVCD on a TV -- and even then, it would involved a messy setup of PCs, cabling, etc. This is not to mention that SVCD supports all sorts of interactivity not available to a DivX disc.

Comparing DivX to S/VCD is redundant as both have obvious roles and applications which are somewhat, though not absolutely, mutually exclusive.

If you see the quality of the DiVX on your tv with DiVX-plus for the Hollywood+ card, it's damn nice quality.

Only problem I still have with this, is the problem with the 1/3 split screen.

Well I have Memento, dig-x DVD-rip, and it's ~700 megs. (1 cd).
It's VERY good quality, much better than if you would fit a VCD on 2 cd's. I'm not sure if it would beat an SVCD on 2 cd's but probably. Since the div-x is on 1 cd it wins in quality anyway (although not in compability).

That div-x has been cut, since it's widescreen, so that the framesize is much smaller (640x277) the file gets smaller ofcourse. And since "Playa" adds the black bars when playing at fullscreen, it's not an issue if you use TV-out.

yeah?

(but, I do prefer SVCD's before anything else, I'm just talking quality here, on little space = 1 cd)
