I truly wonder what the issue is, and why 5.3.6 works flawlessly regarding constant framerate while later versions do not.
I haven’t owned TVAi long enough to know when post 5.3.6 versions were released, and cba to check right now.
EDIT* Just checked. 5.3.6 was released mid november.
Do you know if there are any benefits of running more recent versions than 5.3.6, other than a revamped GUI?
The AI models are still updated in 5.3.6 with the most recent ones you get in 6.0.x, correct?
EDIT* 5.3.6 does not have AI models SDR to HDR or Rhea XL. Currently processing a video. Will update regarding the models available in 5.3.6 vs 6.0.1.0.b models with the “Enable previous models” feature in a bit.
EDIT 2* All models available in 5.3.6 are the exact same as the latest models in the most recent beta v6.0.1.0.b. Difference between the two versions is revamped interface and you won’t have the AI models Rhea XL or SDR to HDR. Checked version and file sizes between the other models and they match down to the exact byte in size. Correct me if I’m wrong.
No noticeable difference in ffmpeg commands between 5.3.6 and v6 beta other than -fps_mode which i assume was just added in the most recent TVAi release to enable the choice of Force CFR. Can only guess at the TVAi compiled ffmpeg build in versions post v5.3.6 is what’s messing with framerate?
For anyone who don’t know where to download older versions, here’s a link to 5.3.6: Topaz Video AI 5.3.5 - 5.3.6 - Topaz Video AI / Releases - Topaz Community
