So I've finished extracting the frames out of my 720p .mkv file

However, when splitting up frames to smaller groups to be upscaled, I was met with this error posted as the title. Cmd Promt below:

I have CUDNN installed ('checked with waifu-caffee') and I'm not sure what's going on here. for some reasons, after extracting frames from the original video (there are~40k .png files), the created 'thread1' folder within 'extracted' only contains frame1 and frame10 (so 2 frames out of 40k)

Update: I've tried tweaking the "-b" value to "8" and "-c" value to "64", nothing seemed to have changed

Hi there,

The error you got occurred when it tried to move files from one folder, 'D:\video2x.v1.0.2\temp\a4274740-4300-11ea-bffe-4f42d25c7044\extracted to another folder, 'D:\video2x.v1.0.2\temp\a4274740-4300-11ea-bffe-4f42d25c7044\extracted\thread1.

In particular, it had a problem trying to move the frame10.png file. It looks like another program (i.e. paint, photo, etc.) was locking that specific file. Can you confirm if that was the case?

Thanks.

Hi there,

I tried looking but couldn't find any other program that was locking the frame10.png file. Moreover, the folder D:\video2x.v1.0.2\temp\a4274740-4300-11ea-bffe-4f42d25c7044\extracted\thread1 has already contained the frame10.png in there.

Does this helps?

Hmm, strange. I'm not sure what happened. Can you try again on a smaller file so you don't need to wait as long?

Thanks.

Things seem to work now, when I opened Command Promt with Administrator privileges. I'm not entirely sure why but could you perhaps add this to the running tutorial so maybe others could avoid getting this error?
