1. SSIM/PSNR metrics in log file
2. Option "qpfile" or "Encode chapter marker as I Frame" option like in TMPGEnc.
3. Add chapter markers as chapters to MP4. See: https://medium.com/@dathanbennett…eg-5e43df269687
4. CRF + 2 Pass mode
5. x264 deadzone-inter/intra options (currently I am not sure that they are useful, however it can not be changed in Voukoder)
