Can’t provide a log or sample, because I didn’t realise this error on time before deleting all the source footage.
What I can remember:
Source was a prores_ks at 2160p and 29.97fps
TVAI 6.0.4
Tested Models: Proteus, Iris, NYX, Rhea, Artemis
Tested Codecs: h264, h265, ProRes HQ
Tested Source: 768x576p @ 25fps, ffv1
My Results
with Frame Interpolation (25 → 29.97)
→ heavy VFR on all tested models and tested codec h264,h265 + ProRes HQ
without Frame Interpolation (orig fps)
Constant Framerate for all models and following codecs: h264, h265
→ slightly VFR for all tested models when output is ProRes
The ProRes VFR thing when doing no frame-interpolation into TVAI, it could be this comes from TVAI drops last/first frame(s)
When doing Frame Interpolation, it’s worser, here must be more than droping one frame and this also happens for h264 + h265
What I can say for sure now TVAI V6… do not use frame interpolation function, it gives you VFR
I did no check yet TVAI sets “CFR force flag” if there are or not double/inverted frames.
Sending this info to the team now.
