Handbrake crf number?

[BlurayHD]

I have my collection of original movies on Bluray and I am converting them to mkv with handbrake but I would like to know if you recommend a crf number?

18 to 20 is a reasonable compromise between file size and quality.

Is recoding necessary? MakeMKV can create mkv out of blu-ray disc, without recoding. It's about remuxing to another container format.

Some people like to have smaller file number not matter what you ask.

I can understand that. I recently ripped ***** . The Bluray was 34.9mb/sec, 31GB. I recoded it to 5.2mb/sec, 4.8GB and the quality on my big TV is fine.

At lower quality .

The Bluray was 34.9mb/sec, 31GB.

The Blu-ray was at high bitrate for a reason.

I recoded it to 5.2mb/sec, 4.8GB and the quality on my big TV is fine.

and the quality on a big TV is much lower.

But some people simply don't see the huge quality loss, so horses for courses I guess - "but not for me" as the old song goes

The worst part was I missed cropping a 15 second scene from 2.35:1 back to 16:9.

Seriously, I did a CRF 18 recode on my Bluray. The final video bitrate was 3837kb/sec. Maybe I should wind my 5200kb/sec back a bit eh!

Only when I got down to a CRF of 10 did I get close to the bluray's disk rate. Disk = 29900, CRF 10 = 28400.

I notice nobody has yet criticised CRF 18 even though it produces, at least here, "woeful" bitrates.

Keep the source as it is, is already digital, there is no need to re-encode, loosing quality and wasting resources and time
