I’ve upscaled a lot of 1080p H265 episodes from 1080p to 4K, but since 3.5.1 (although the processing still takes the same amount of time – approx 8 hours on my M1 Macbook Pro) the output only seems to be like ± 2GB which is roughly half the episode.
Used settings:
Preset: Upscale to 4K
Output resolution: 2x Upscale (to prevent letterbox)
Enhancement profile: Proteus Progressive
Enhancement paramters: auto
Output encoder: H265 Main10
Bitrate: Constant 16Mbit
Audio: none
Container: MP4
Since the community forum learned me that more people seem to expect issues with 3.5.1 I’ll try to downgrade to 3.5.0 and do another run… Will update you tomorrow
