Yes, I guess the scene cut detection could be less accurate than a lossless codec with only i-frames.nekno wrote: ↑Wed Jan 22, 2025 8:50 pmWhen using an mp4 container to generate my own Balanced content mappings, I will diff them against your T3 generated mappings, and see one-frame differences in the duration of scenes, or differences in trims that match to the tenths or hundredths, but are different by thousandths+.
Are those a result of dropped frames in the HEVC decoding, or perhaps something else?
I could see different versions of Resolve perhaps including changes in the DV algo or tuning that would result in different trims, but the differences in scene duration is a problem that could result in a lot of light/dark flashing between bright/dim scenes.
Your L1 plot will show 10 000nits spikes when there are dropped framesHow do you test for dropped frames, what are the telltale signs?
yesIs Media Offline what you're looking for?
MP4 works a lot better but I've seen 2-3 times ''media offline'' clip in the test I did. So it still can drop frame.When using an mkv container I see a lot of "Media Offline" scenes when scrubbing through the timeline, and I didn't see that with an mp4 container. So I'm wondering how I know if the mp4 container is indeed dropping frames.
