I imported a video and applied the SDR to HDR enhancement as well as the Proteus default enhancement because under the SDR to HDR option it recommends adding an enhancement to reduce artifacts. The input file is 11.2gb and the output file is 7.74gb. That seems unusual to me. I did notice the input file has a variable frame rate and the output file has a constant frame rate. Would that make that much of a file size difference and is there no way to output with a variable frame rate in Topaz Video AI?
Here is the media information:
