I recently bought a new graphics card which now enables me to take advantage of CUDA hardware acceleration for encoding/decoding.
My first trial was with ‘Hostiles’ which processed the backup in around 30 minutes as opposed to 38 minutes with software encoding/decoding.
As a ‘Partial’ copy the file size to be compressed to 25GB was 34GB and from the slider setting suggested an approximate final size of 23.90GB. After completion and the ‘save the log file’ window shown I noticed the data written was 34.47GB and the data written was 14.8GB, somewhat smaller than expected.
Wondering if the CUDA process might have an effect, I saw the software encoding/decoding version came out the same size as well.
I have now tried two more blu ray titles and each came out at 14GB when set for 25GB. If a backup is done without compression the file is the same size as the original (not surprising).
Has anyone else seen this behaviour?
Attached are two logs, one with CUDA, the other without.
Edit:
Just reinstalled 1.1.9.4 and backed up the same blu ray titles as Partial for 25GB. The output file sizes are now 23.03GB and 23.40GB.
Going to install 1.2.2.0 again and see if the small output file size is repeatable.
