BD-Rebuilder 25gb Quick Encode Option

[richx03]

Hello everyone! Sorry for the newbie question. I put all my backups on a BD-25 with a custom setting size of 23,800 mb. But I was wondering if there is a difference if I put the encoder settings at Automatic quality Settings vs. High Speed Option (BD-25). If i just put the check mark on the automatic quality settings will it automatically do the High Speed option anyway? And when I put the check next to High Speed Option (BD-25) it has a check mark on the one pass ABR encoding. What's the difference between the ABR and CRF encoding? And from what I know so far, since i'm backing it up on a BD-25 there is pretty much no difference between one pass and two pass right?

Sorry, I know a lot of questions.. Just in the end I was wondering what the best way would be to encode to a BD-25 taking the least amount of time possible, but at the same time keeping quality high. Thanks!

When you select "Automatic" is chooses the quality level based upon several factors and could, depending upon the source, result a any of several settings. It never picks "High Speed", that can only be selected by the user.

ABR builds the disc using output size as the guiding factor. CRF creates a constant quality without reguard for size. When you choose CRF, BD-RB attempts to "predict" the output size by sampling the source with several CRF values.

There is ALWAYS a difference between one-pass and two-pass ABR. But when the bitrate is high, it is often hard to see it.

My recommendation is to set "Automatic" and forget it. That way it can adjust for difficult sources.

I Jdobbs, I am new here too with this software and all I can say is that I'm very impressed. I was afraid of the output quality on a big screen (106'' screen with a Panasonic PT-AE4000).

I use Avatar 43GB, and output it to a BD-25 using 'automatic setting', it took 8 hours on my low end PC. Which is not too bad I think. I did try the highest quality but I stop it after 20 hours, it was way to hard for my old AMD X2 3800.

Anyhow, I should say that comparing the original Avatar and the backup one, the differences were minimal, a little softer but no artifacts or compression issues, really amazing and I should say I'm very picky on video quality.
