Where is the limit of compressing?

[castellanos]

Hi there:
I would like to make a back up of "The Lord of The Ring - The Return of The King", everybody knows how long is the film (over 3 hs!).
Of course it is possible to do the back up, I use DVD Shrink, still, taking off the extras, language and subtitles I don't want, the film is almost 7 GB...
So the question is: If I want to make a buck up on a DVD-5, Where is the limit to compress and not to get a very bad video quality?
Greetings!

I have seen some that was acceptable as low as 60%. Others looked bad at 85%. But remember that was what was acceptable to me. You may not find it so.

I don't think you can apply a limit in general I think you have to go by each individual movie.
.
I've seen 5gig movies compressed down to 1.5gb and look better than vhs. (1.3vid .2aud)
.
I think you'll be happily surprised with a 4.3gb backup of ROTK.

I see, thanks for the advice! :cool:

If you're a quality freak like me you won't be pleased with 3h20 on one dvd, especially done with a transcoder.

I'd rather split it to 2 DVDs.

I tried this movie as you describe and was not happy.
I went back and did it over 2 discs.

I did it with CCE and was VERY pleased with the results.

I'm trying to reencode it with CCE too and I've tried encoding with the default DVD2SVCD settings:
Min. bitrate: 2000
Max. bitrate: 9000
Avg. Bitrate: 2713

It's less blocky then DVD2one, but it has a lot more mosquito noise. So i want to reencode it again, with some other settings.
I was wondering what minimum and maximum bitrate you used?

thx

[Lagoon]

Use 0 as a minimum bitrate, 2000 is a waste of bits.

Keep the max as high as possible (9800 - audio bitrate)

The mosquito noise is due to the reencoding, there isnt much you can do at a bitrate of 2713, transcoding makes way more blocks, but less noise.

Hi

I saw last day a two CD's backup of "the return of the king" (about 1.4 GB, VCD format) and although quality is not perfect it's quite good, so I think using DVD shrink to get it into a DVD-5 will give you a good quality. Anyway I've got some DVD-9 converted to DVD-5 with DVD shrink, and I can't see the difference. Some people won't agree my opinion so the best choice is try&record.

I think the best option is to create an avi and burn it in a DVD...
Then you can get a 4 GB avi, with an incredible quality... but of course there is another problem, How big can be the avi file? for that reason, I am also asking in the DivX Encoding section.
See this link. (http://forum.doom9.org/showthread.php?s=&threadid=77404)

VCD format is horrible, it may have no blocks or noise, but the resolution and the loss of detail is quite enormous.

If you plan to make an AVI, use XviD @ Q2, and not DivX, this will give you way better quality than dvdshrink, AVI has no size limit, just make sure your HDD is in NTFS file format if you plan to make it bigger than 4GB.

Still, the best solution is to simply split it without any compression, switching discs after 1h40 isn't that annoying, for me anyway.

Using DVD-Rebuilder with LOTR ROTK, compression at 53%, using CCE, and viewing on a 27" and 32" TV, the backup looks good to me.

But keep in mind, even the original is not so great of a source.

Check out CCE for these long movies unless you really don't care about splitting over two disc.

Hi, I've made the back up of "The Return Of The King" on an avi file, in the process I added permanent subtitles too.
I used Dr. DivX and the Bitrate was 2500 KBit/s... finally the avi was (+ ó -) 3.1GB... and the quality was excelent.
Pitty, It can be only played on a PC.
Greetings! :D

This may not be directly related to this particular thread, but if your anything like myself, I like to rip the best quality possible. I didnt even bother with the return of the king single disc. With the other two previous movies I ripped the extended versions instead, and made episodes out of them. The extended version of R.O.T.K. is due out in August, if you can wait that long. That way you dont have to worry much about preserving the quality. FYI- the extended version is said to be close to five hours long.

to answer the original question....in your own head and eyes.

as you can see everyone has different opinions on what they find acceptable. so make some tests yourself and then you can decide whats your limit. :)
