I inspected the results using each of the frame interpolation models in an SD to HD upscale scenario with identical footage and upscale settings. Apollo negatively impacted the overall output quality with respect to the upscale settings. What looked good without frame interpolation suddenly looked muddy or had halos, lines, or artifacts that were not present without Apollo. Chronos had a near-zero impact on quality in general, with the only issue being those jump cut artifacts. So, the least-bad solution is what I’ve been using. I’d like it to be better if it can be.
I ran some tests here I think you should consider. In general, I have found that I get better quality results when I upscale before interpolating—but it’s much slower. Anyway, it might not help at all since I have not seen similar results to what you describe.
I’ve seen that blurry patch artifact appear several times during a short slomo, using 3.2.4, but I can’t recall if it was when using Apollo or Chronos, but I can say that it was not at jump cuts. It may have been at a jitter point though, as it was an old shaky handheld video. I never saw it with any previous version.
I just re-did it using a different model but I will look out for it from now on and report back if I see it again.
Hi, I don’t understand why temp files are not created in Temp folder defined in Preferences.
For example, when I export a video in MP4, it first creates a _model_temp.mp4 then a _model.mp4, in the same folder.
As I have huge RAM, I’d be interested to write _model_temp.mp4 files into a RAM disk, before writing the _model.mp4 file.
Thanks for replying.
