lossless option should not use veryslow preset, it takes up 95% of total time.
You should use ultrafast or use hardware encoding (amf for amd and nvenc for nvidia) which makes sense because you are detecting hardware support (opencl). Best would be to leave video encoding to users

also an issue, the settings.py file is bundled in windows package as compiled .pyc file

Good point, I'll take a look into amf and nvenc. If you're using BF from source you can change a few of the FFMPEG options, including the veryslow preset, in settings.py to something else.

still veryslow in latest release, 0.2.4a4. Can't you just change it to ultrafast, what are you gaining from it? It takes up to 95% of total time for no reason

@dailylama Can you compile fork with fixed option? I can make any tests possible at my machine if needed. Discord: naposidi#2247 for fast communications.
