I record a lot of game footage, especially for simracing. The size of the content is growing rather large, and I’m looking to en masse re-encode the world of footage, to save space. Primarily, it’s simracing footage, like DIrt Rally 2.0 and Assetto Corsa. Occasionally it’s Borderlands, CODMW. I use handbrake to convert files.
One the one hand, I post this looking for anyone with some conversion settings to test, that works for them, beyond the built-in presets. On the other hand, it’s just nice to spread some excellent software that’s free and better than many paid licensed software.
Anyway getting back to specifics: the saved original videos either come from Nvidia shadowplay (at 50Mbp/s bitrate) or OBS recordings. Resolutions are 5120x1440, 2560x1440 or 1920x1080 for VR.
In a sample batch conversion, 20 files (5120x1440 resolution) totalling 25.3Gb re-encoded down to 15.7Gb. That’s about 37% compression, using H.265 (Nvidia NVEnc) at a constant frame rate of 60. Audio is AAC (avcodec) at 160bps bitrate (mixdown to stereo), filter Decomb, same resolution (no downscale), RF Quality value is 24. Encoder preset is 1 click up from Slow, with the profile and level set to Auto. Image quality to the average eye, seems excellent. This is mostly on videos where every pixel is changing from frame to frame, and at least (when I’m recording in cockpit, not from the game replay), it’s only really the windscreen and mirrors, that are always changing a lot from frame to frame.
Blue sky would be some gorgeous human being, uses handbrake, and has better settings for a pleb such as myself to use.
Runner up: someone uses other software and has good settings, they can share, so I can attempt to reproduce the conversion settings in handbrake.
Dead last: crickets
Saving grace: if you haven’t tried handbrake, and it fits your use-case, the presets are very good, and will get you 90% of the way.
One day, I’ll get this working as a service on a server, where you just upload it, and it automagically spits out tabaco and a still excellent quality video file, but at like, half the filesize. That’s the dream, at least.
