Another transcoder like shrink?

[|Supreme|]

I'm curious if theres a program that can shrink extras more than shrink can. Normally when I'm backing up movies, usually I like to keep the extras but I wouldn't mind them at the lowest possible quality.. Also are there programs that when they do that utilize the CCE encoder?

DVD Rebuilder. None better.

i think you may find that you are shooting yourself in the foot trying to re-encode a ripped dvd....

you will probably find that after you have spent hours re-encoding that your encoded file is larger than the original mpeg stream. This is because the big studios are exceedingly efficient at their mpeg compression and we..unfortunately...are not.

so for the sake of time and actually getting a smaller file, transcoding is usually used.

Another DVD-RB vote. 1/2 D1/1/2 space from extras option and/or steal space (10/25/33/50%).

Have no idea what Grey is getting at - sure if you go and try and re-encode a given file at an arbitrary bitrate, it *may* end up bigger than the source, but that's what tool like Rebuilder are for...Scan your source, and give you your needed reductions to fit. Also, there's the add-ons for RB like RB-Opt that you can tweak the ECL file and set bitrates for each AVS/cell individually (ie dump bitrate on credits/etc)..

ps - You don't *need* CCE - you might want to give HCenc a try (free - inc. with DVD-RB).

DVDRB will take ages to recode a dvd

DVDRB will take ages to recode a dvd

Great quality takes more time.

A quick question:

Which external MPEG Encoder makes the re-encoding time the fastest with DVDRB but still gives great quality,is it CCE?

I think I have to disagree with your view in terms of practical experience. I will agree that large studios have means to to do a DVD much more efficiently than what a home amateur can, however I have found that many 90~100 minute movies take up much more space than they need.

You can take the video stream through CCE on a 4800VBR encode at 4 passes and it will produce a really crisp output. Even at 3400kbps, picture can be clear and crisp.

The idea behind DVD Rebuilder (strip the streams, downgrade the frame size on extras if requested and re-encode with a first class MPEG encoder like TMPGENC or CCE) is a winner.

Yes, the whole thing takes time (encoding a 90 minute movie in 4 passes on a really quick PC takes more than 3 hours) and the real catch is whether the whole work is done reliably and the resulding DVD structure is valid.

My negative view on DVD Rebuilder is that it is a collection of programs, codecs and utilities that are tricky to setup correctly. But, in some arts, difficulty is the driving force, isn't it?

Heartily agree with that. Took me quite a while to set up the first time, one of the earliest betas, and had to look hard for an old, obsolete MPEG2Dec version to get it to work.

BUT, Rocka's installer has removed all difficulty from installing DVDRB. If it doesn't work for someone, I'd lean heavily towards suspecting the user or his/her machine. BTW, I go 2-pass with CCE, and it completes in about 1.5x run time, all up.

my practical experience was with the BTTF project..the original DVD was 9800VBR and encoding at any arbitrary(CbR) bitrate produced a MUCH larger file...I would have to encode at like 3000 cbr to even match the size...and this is on a file that had already gone through DVD-Shrink and been compressed considerably...so that is my practical experience. I realize VBR will produce somewhat smaller file sizes but are you saying your software can do it better and keep it near the quality of the original? Thats what i'm getting at...and my point WAS this is why re-encoding isn't used..the original question was why aren't encoders used. If theres a terrible flaw in my reasoning I'd love to be corrected before i get more weird looks :P

That in itself is a conflicting question. CCE is an encoder, and transcoders don't use encoders

[|Supreme|]

yeah.. I just mainly would prefer to lower the quality of the extras as much as I want. Not like to extreme low values but maybe 70-80% quality reduction on some of them. Also is there software that lets you take out some of the videos you don't want.. or certain intro videos you don't want?

I guess Im kind of hoping for an all in one type of thing. Lower quality of extras more than shrink and the ability to remove unwanted videos that show when you first start the movie (previews, warnings). I'll check into the ones you posted.

Also.. does shrink transcode? I don't really understand the difference between encoding and transcoding.

[Mister Flonk-Flonk]

Why would anybody use CBR when recompressing stuff to fit on a DVD-5?

[jimmalenko]

VOBBlanker can remove certain extras that you don't want.

DVDShrink is a transcoder.

From the glossary - https://www.videohelp.com/glossary -

Encoding
Encoding is the process of changing data from one form into another according to a set of rules specifiec by a codec. The data is usually a file containing audio, video or still image. Often the encoding is done to make a file compatible with specific hardware (such as a DVD Player) or to compress or reduce the space the data occupies.

Common video encoding methods are DivX, MPEG-1, MPEG-2 and MPEG-4. A common audio encoding method is MP3 although many others exist including MPEG1 audio, DTS, and Dolby Digital.

Transcoding
On this site generally another name for encoding.

A more technical term would be "The reformatting of content, without changing the source, to another type of content - most often of a different format than the original (but does not have to be)"

An encoder starts from scratch, decompressing your source to raw uncompressed frames and assigns bits to all frames. A transcoder attempts to find points in consecutive frames that could be represented by the same information once, leaving the information that changes between frames as-is. This is why there are vast differences in the amount of shrinkage you can get depending on the content you have.

The links to vobblanker. and dvdstripper don't seem to work Also I'm trying out dvd rebuilder.. i like how its able to lower the quality of the extras Still messing around with it.
