Compressing DVD

[TheRyuu]

Just curious as what the "best option" would be:

Note, the dvd cannot be decrypted in dvd shrink (why I'm using dvd decrypter):

Option 1:
Use DVD Decrypter to decrypt the dvd and store it as files with audio and video ts folders. Then use DVD Shrink to compress it all.

Option 2:
Use DVD Decrypter to decrypt the dvd and store it as an iso file and then mount in alcohol. Then use DVD Shrink to compress it all.

Option 3:
Do the whole thing in DVD X Copy.


I ALSO want to compare how dvd x copy and dvd shrink compress a dvd. How could I go about doing this?

And feel free to make your own up if you don't like mine.

Use option 1.

Well since I don't know anything about DVD X Copy, I can't comment on that. However out of Options 1 and 2, I'd pick Option 1, why go through the extra step of mounting an iso?

Option 2. You don't have to mount the ISO, Shrink can open ISO files.

Don't transcode it. Use DVD Rebuilder + DVD Decryptor instead. It will give you much better quality then using something like DVD Shrink. However, if you really care about the time it takes (transcoding will always be faster then encoding), don't care about quality, or it does not need much compression then DVD Shrink is fine.

What is Transcoding?

With Option 1, were DVD Decrypter creats the video and audio ts files, I don't get the option to perform a deep analasys. Why not? And is that bad?

With using Deep Analysis, the number of samples taken in deep analysis is increased. having more sample marks enables better and more accurate calculation while compressing, and the interpolation needed between sample marks is decreased, these interpolation may have lead to artifacts when using normal analysis... So the theory is (which is somewhat proven from comparing samples) that you will have less artifacting thus showing a sharper picture. So no, deep analysis is NOT a bad thing.

Courtesy of wikipedia:
Transcoding is the act of converting digital content from one (usually lossy) format to another. It involves first decoding/decompressing the original data to a raw intermediate format (ie, PCM for audio or YUV for video) that mimics standard playback of the lossy content and then re-encoding this into the target format.

Keep in mind with using DVDshrink (assuming youre new to DVD encoding) the more compression you use, the worse the quality of your final output will be, no matter if you use deep analysis or not...

I read a post by KoolDrew about using DVDrebuilder for encoding, which is pretty much what I do... Although, I use CCE SP as my encoder instead of the free HC or Qenc...You should really head over to a place like CDFreaks,doom9, or Afterdawn.. It's where all of us encoding nerds hang out and share info, experience, methods, etc...
