Editing HEVC fails to save...gets 10% or so and hangs

[Ronstang]

I usually edit the TS files and then encode but all my Cable TV content is not interlaced but Telecined so I have to run an IVTC filter on all content to get it to true 24 fps without issue. With TV shows if I edit the TS file and then encode I get problems because the editing throws off the cadence of the telecine so I want to encode first and then edit.

I tried this the other day on several files but each time I try to save the edit it fails. I am using a default HEVC profile for TV shows in ffmpeg because I know VRD does not support the 10 bit color I must use for movies to maintain quality so these files are the basic HEVC encode using NVENC.

Any ideas?

Try running the file through QuickStream Fix first. That might help. Although if it has to delete any bad frames then that could throw off your cadence and bork the reverse telecine.

OK Dan, I'll try that but no worries if it's bad I'll just wait for it to come on again. These are mostly shows on The Science Channel so they repeat a lot. Thanks

It worked on one file to run it through QSF first but now every HEVC file I try to edit is painful at best to edit as it is almost impossible to navigate the video it is so slow. The reaction of the slider is so bad you consistently over run where you are trying to be.....then when you finally get all the cut points added the file won't save at all now and looking at task manager VRD is using 99% of the cpu.

The one that was successful is the best file I've ever had of a TV show but I can't get it to repeat.

This behavior is only when trying to edit HEVC videos, I just edited a TS file without shutting VRD or the machine down and it was not sluggish at all so this has something to do with HEVC only.

Nope...no matter what I do when ever I try to save and edited HEVC regardless of which encoding profile I use my CPU usage spikes to 100% and nothing happens until it fails. It appears VRD just isn't compatible with HEVC....but It does such a great job on my TS files that I no longer have sync issues when I edit TV shows/movies with commercials in them so I don't really care. I have no need to edit HEVC for the most part.
