Which 700MB DVD rip format is the best

Hi guys,

I download a lot of movies and I'm finding that downloading full length movies running into GBs takes too much time even on a very high speed connection. I was recently looking at some 700MB DVD rips and I felt that the trade-off to 700MB is okay with some movies but not with all.

I was wondering

1) which format is the best i.e. the least lossy when it comes to DVD ripped versions of these movies. DivX, XviD, mkv etc...?

2) how are the movies ripped exactly to 700MB? Is there a quality trade-off? i.e. if I am allowed to rip the movie beyond 700MB, would I get better quality?(and would it be like...if the movie is longer the quality might be less as it would have to be accomodated in a fixed video size of 700MB?)
 
Xvid is widely accepted as the better format..you can use AutoGK to convert mpg/vob files to xvid/divx very easily. And of course, the more the size/the shorter the length, the better the quality! I usually rip my dvds to 740MB, so that i can burn 6 of these onto a dvd (740x6=4440MB!)
 
Its very much dependent on the source DVD video from which it is being ripped... But In my experience of ripping DVDs (more than 300 DVDs) I have come to clear conclusions.

Movies/Scenes with a lot of motion/speed as well as a large field of vision (detailed background) are better encoded using XVid codec. Whereas slow scenes where focus is more on a single characters and his/her expressions are better encoded using DivX.

If thats hard to figure out, then I've found most hindi movies are better looking with DivX while english movies (esp. action movies) are better looking in XVid!!
 
The size mainly depends on the length of the video and the bit rate you use, so if the video is say only half an hour long and you rip it to 700 xvid/divx file, then the video is going to have a very high bit rate and and hence will be of a very good quality, and if it's say 2hrs long then to rip onto a 700mb file you will have to use a lower bit rate and the quality will deteriorate . That's basically the logic.

I personally use winavi and super.
 
H.264 (or x.264...donno the difference) is supposed to be lossless I guess, but these .mkv files are very difficult to play. It takes an eternity to move the slider and get to a new location of the video.

Also noticed a problem with VBR videos (videos with variable bit rate). Slider takes a long time to re-position.

So XviD and DivX are the main encoding formats. And I guess bit rate is decided based on the movie length.....correct?

I've also seen some files named with a .divx and a .xvid extension. Are they different from these .avi files encoded with DivX and XviD?
 
H.264 + ac3/multichannel aac =nirvana :P
H.264 is not supposed to be lossless,though there is a lossless version of it..
 
I hope you did not download the kvcd rips , which though are ~700 MB, but use the highly inefficient MPEG1 compression :bleh:
 
Well...yes I have downloaded a couple of kvcd rips. I guess the aXXo rips are good. I never really verified the rip source with the quality. I think I need to run these files through GSpot and see what rips are XviD.

Do you mean inefficient as in filesize is large? MPEG-1 might be ineffiicient but the quality is same as MPEG-2 wouldn't you agree? I remember getting a lot of um...special :P VCD movies when I was in college. They were all MPEG-1 .dat files. Good video quality on most of them.

And the best part is that MPEG-1 does not require a lot of processing so it runs well on old systems. My old P1 200Mhz MMX would peak out with DivX 4 encoded content. DivX 5 was a frame by frame nightmare.
 
There are primarily two things that would determine the quality of Rips

Bitrate: The higher the bitrate, the better the quality and the bigger the filesize

Compression algorithm: The more efficient (and also more complex) the algorithm, the better the quality for the same filesize

Thus MPEG4 (DivX, xVid, mp4) > MPEG2 (typically used for DVDs) > MPEG 1 (outdated and used mostly on VCDs)

Thus for the same filesize, a xvid/divx would look better than a MPEg1 compressed move (your kvcd rips)

An obvious impact of better and more cmplx algorithms is that they require more processing power during decompression before rendering...

Which is why even though MPEg1 does not rquire anything more than a P-1 200mhz system, the picture quality of a 700 MB mpeg 1 would be far worse than a 700MB xVid

Oh, and BTW aXXo is just the nick of a famous ripper and his rips are typically 700MB xvid rips
 
Thanks for the detailed explanation. What's your opinion on XviD v/s DivX? I personally tend to favour XviD.
aXXo is a gr8 fella. Am really appreciating his rips :D . I've got sooo many movies now wondering what to do for space. Over 500 gigs to be exact. Waiting for HDD prices to come down so I can get 500GB X 2 HDDs (I buy 1:1 so I always have a backup of my stuff. So price is very important for me.)
 
H.264 seems to be the best format for encoding ... but takes a lot more time to encode than xvid, atleast on my system ... so it's xvid ftw
 
XviD v/s DivX
Click to expand...

I frankly can't tell the difference...there are too many other variable involved for there to be a discernible difference between thse two extremely efficient algos...

Also, both xVid and DivX are derived from the same underlying MPEG4 compression
 
How are u guys encoding using H.264

using the opensource x264 Codec or using Nero digital.

Nero Digital has given me gr8 compression and quality.

Also AAC supports AC3 5.1 compression to AAC5.1.

Are there any more ways of encoding to H.264 but keeping AVI or MP4 As Container.

I have found Nero Digital to be faster than Xvid while compressing videos on my A64 3000+
 
Don't do much encoding these days as I don't get many DVD movies to rip. Just prefer to download them.

As far as I know. H.264 encoding is done with a .mkv container. Not sure if an .avi can accomodate H.264.

Just checked and I've changed my mind. DivX seems better. But yeah...too many variables (video size, bit rate etc.)to tell the difference.
 
okie... silly question..... if i want to rip my dvd the what bit rate for xvid codec and mp3 lame codec should i use..????

i generally go for 1000 kbps for video and 128 or 96 kbps for audio.... is it okie..???
 
Well I checked most of the videos. 1000 kbps and above is the general XviD and DivX bit rate which gives good quality. A little higher would be better.

For mp3's my experience is that 320 kbps encoded mp3s are satisfactory. Donno what it should be for movies.

H.264...well give me a good decoder that does not jerk or skip and it'll become popular by itself.
 
Nothing Can Beat the Quality Of True DVD9(in Current Main Stream Format)

Hate These Compression Formats :@

& in Music mp3 S**K...Lossy Format Again,Flac Rips the Best in Terms of Quality :hap2:
 
x264 is stable and very popular (torrent ;) )
MainConcept encoder has the features..

but good thing is u can get almost daily build's of x264..
