@videofan3d

Thank you very much for your work.

I've tried the MVC encoder and the first impression satisfies me.
I didn't do many test to determine suitable parameters for an encode.
With the idea to have high quality encode I chose at a glance
-u 1 -rf 16 -cqp 16 17 19 -Bpyramid on, so I got
Bitrate control CQP
QPI,QPP,QPB 16,17,19
GOP structure:
GOP length 24
I-/P-frame distance 4
IDR-frame interval 0
GOP type Opened
Num of slices 6
Target usage 1 (quality)

Then
Processing started
Frame number: 232608
Processing finished in 148433.81 seconds, which is 41:13:54.
The last result seems not very bad - 1.567 3Dfps

These, practically, random chosen parameters for QP:
QPI, QPP, QPB 16, 17, 19
turned out to be as used by the original encoder.
The file sizes, average bit-rate, bit-rate vs time are undistinguished compared to the source. Even the PSNR for every color channel is 100 dB.
Some examples.
encode:10,591 - 21,149 kbps
source: 10,608 - 21,166 kbps

Two screens from left eye frames #27,349 (00:19:00.681) where the bit-rate is about 34 Mbps.
