Hi! I use proxies to edit 4k videos. It works great and allows me to edit videos that would otherwise make my computer too laggy.
Now, the issue I have is that in some cases I want to be able to properly see the details of the images. For example, right now I’m trying to make a seamless cut, and I need to be able to see whether the person has their eyes open or not.
So, I want to quickly disable proxies for a couple of clips, find the right frames for the cut, and then re-enable proxies. I tried with the “Use proxy” and with the “Disable proxy” options, but they don’t seem to do what I want.
Unchecking “Use proxy” opens a window that says “Turn proxy off” in the title and has a “Converting” progress bar. In the console, it prints a long list of errors like these:
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7fc1ab60d0c0] st: 0 edit list: 1 Missing key frame while searching for timestamp: 1000
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7fc1ab60d0c0] st: 0 edit list 1 Cannot find an index entry before timestamp: 1000.
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7fc198e5e280] st: 0 edit list: 1 Missing key frame while searching for timestamp: 1000
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7fc198e5e280] st: 0 edit list 1 Cannot find an index entry before timestamp: 1000.
It takes a long time, even though the progress bar starts full. You can close the window, but the processing of whatever it’s doing in the background keeps going (using 100% CPU).
I eventually gave up on this, closed the file and tried to open it again with proxy disabled, and in that case it didn’t even open (it’s an hour long video, with plenty of cuts). I had to re-enable “Use proxy” in order to be able to open the file.
The “disable proxy” button for the clip seems to cause the same console errors and also causes shotcut to take a lot of CPU. It seems to do what I want, but when unchecking it again, it seems like it doesn’t revert to the proxy, or at least the whole thing starts to stutter, like it’s not working…
Is what I want possible, or is it not expected to work like this?
