Would 10% compressiblity check be better than 5% ?

[N_F]

Results from the tests I've run (I decided to use quant 2 sizes even though I got other suggestions from Manono and Jonny), movies was divided in the middle, end credits cut out:

Rules of Engagement

1st - 1 165 966 62%
2nd - 704 542 38%


The Birds

1st - 1 540 850 52%
2nd - 1 429 486 48%


The Expert

1st - 627 420 50%
2nd - 638 662 50%


X-Men

1st - 614 450 56%
2nd - 491 694 44%


Night of the Living Dead

1st - 576 236 46%
2nd - 625 100 54%


A Night at the Roxbury

1st - 615 250 50%
2nd - 621 142 50%


As can be expected it varies greatly from movie to movie. Though 4 of the 6 movies I did this with showed quite even numbers, while Rules of Engagement showed a huge difference.


Anyway, I've gone over to "your" way of doing 2 CD rips. It's much more comfortable since among other things you don't have to divide the subtitles and deal with asynchrous streams.

Hi-

Good work N_F. Remind me not to encode The Birds. You've got almost a 3 GB first pass there. Must be real hard to compress to 2 CDs.

Nice work!
It's curious to see that for some movies the difference is very little

Yeah, though I used C3D for my encoding since it's a bit noisy. Since it won't affect the test values I removed it for the test to increase the speed. I was quite happy with the results, though I guess it could have been better. I refuse to go over 2 CDs when it's not even breaking the 2h barrier.


Night of the Living Dead is the only B&W movie I've encoded so far that actually compresses very well. Though it should be noted it was the 30th anniversary edition, it's quite possible they cleaned it up.
