Recommended Shrink compression?

[Chip718]

What is the lowest compression recommended in Shrink without a noticeable difference in video quality? TIA

Good question. You can just do a 1 minute scene, and manually play with the slider. Spend 1/2 hour and do 10 different settings and see for yourself.

I never go below 70% (haven't had a straight movie backup yet below that), and I'm often in the 90% range.

I just ripped Matrix Reloaded and copied just the movie onto one DVD. It came in at 73% and looks beautiful on my 60" projection TV. I cannot see a difference compared to the original. Was afraid it wouldn't look good.

I start noticing drops after 60% on cartoons, about 70% on movies... but again, it depends on the source...

Even VCDs look good on Projection TVs, since the picture is very small and projected into the size of your screen.

You'll see a very big difference on non-projection TVs the bigger the screen size, especially the closer you are to the screen.


You can avoid compression if you get rid of the extras and the alternate audio tracks...such as other languages and commentary.
That's not always possible though...but helps a great deal.

I don't really think there is a set number as far as a line between ok and bad.. It's a given one would go for the least amount of compression they can get away with... It's not like 78% is fine and then at 77% it goes to crap.

the only real decision is the trade off on what you need or have to to get rid of.. If it's just a few % points I'll leave in more extras and so on...

Type of films tend to be an issue also. It's seems that I can back up lighter color, bright filmed movies at a higher compression then really dark films. For example Platoon backed up with a lot of break up/artifacts for me in the dark night jungle parts of the film Vs say t2 at the close to the same level.. (60%)

Of course on some level compression numbers comes down to a take it or leave it sort of thing. If you have removed everything you are willing to not have on a backup, and it's still 68%.. errrrrr well ya back it up like that or you do not. No real way to some how all of sudden get back 15% more space out nowhere.

I have shrunk movies down to 53-57 % and can't tell a difference on a 27" tv.

When this happens there is a way to save a few more %s.
Simply applying "Still Pictures" to the end-credits.
The playback will be seamless, and this usually lowers the required compression by anything between 2 to 5% (more if the end-credits are very long).

I know this has been discussed a lot on here, but does anyone have a definitive may to copy a working root menu and movie only? I read a bunch of post and guides, and I tried a few suggestions, but I couldn't get it to work correctly. Anyone now of a good way to do it that a newbie won't screw it up?

I was planning on backing up Bad Boys 2, and Pirates of the Caribbean on 2 disks each since they are both close to 2.5 hours, but if I bump down the compression without to much quality loss maybe using only 1 disk is possible.

[ddlooping]

Chip718, this is probably not the reply you were hoping for, but if you first intended to split the DVDs to two DVD-Rs the menus would have been pretty useless.

So I'd suggest you make movie-only backups of both.
If you have some room left you can even include a few extras.

If the movie is too big like 8Gig + I use 2 DVD-Rs, backup movie only and I use no compression. I do care more about the quality than other things. If the movie gets compressed too much I can notice the movie to be some how darker than the original and the sound is more thin and bright.

judgmentday, if you're using a transcoder like DVD2One or DVD Shrink, you might notice a volume drop, but the "character" of the sound shouldn't change.

Doesn't the audio get shrunk to a lower bit rate?

[ddlooping]

Whether compression is used or not, the audio streams are left untouched (with DVD Shrink anyway).

lol, no...its all in your head! What? Shh! Im typing....
