I tried various combinations of –slices parameters. Nothing helped.
Few extra steps I that did:
Installed demo version of more advanced TMPGEnc tool Video Mastering Works that supports H.265, to check if this would work with x264 lossless. Nope, same problem 150x slower encoding.
I also sent an email asking TMPGEnc support team to help to figure out correct x264 settings for slice structure of a frame in H.264.
The Video Mastering Works shows the Video, GOP, Frame structure parameters in its settings, they result in AVCH 2.0 compliant file.
I learned from this, tried to replicate the right set of x264 parameters.
Now it works!
It was so simple.
Only few key parameters/settings have to be followed, in combination to others from BluRay/AVCHD default:
· Multi-slice has to be enabled, set to 4.
· --bluray-compat has to be manually added to Command Line
· VBV Buffer Size = 3213 kB
· AVC Profile High Level set = 4.2
· X264>Frames>GOP Size Max = 50 (for deinterlaced to 50fps video)
The workflow:
Starting from default Hardware restricted BluRay/AVCHD:
Is it OK to have Buffer Size and Max Fill Rate at the same size, and = 24000 kbits ?
Just an idea, if you would make a preset for AVCHD 2.0 in Hybrid.
At least the AVCHD Progressive preset for Hardware Restrictions only, not the Create Structure.
Hybrid would be the only one none-commercial SW tool that can encode for AVCHD Progressive, BDAV (at least TMPGENc Authoring tools accepting this without re-encoding)
