Hi!

First of all, Thanks for this tool!

I've encontered an error upscaling a file: the upscale process worked great but had a crash when it was time to encode the upscaled video.

After some tests, i was able to get it working by shortening the file name and removing a ' in the file name. I'm pretty sure the second one was the cause.

If this happens to any of you and you kept the frames: rename the file, rename the folder containing the frames and correct the path in tht .txt file using notepad++ replace function.

I would suggest for Qualityscaler and other tools to check for this and rename / remove the unsupported character if needed.

It may be interesting to check for path lengh aswell as windows 11 (as far as i know) still has a max path lengh fixed at 260 characters which can be very easilly reached when the file name is already long + qualityscaler tags.
For example a video named "this is the great video of my trip to las vegas.mp4" at C:\Users\Test\Videos is already 176 char long.

C:\Users\test\Videos\this is the great video of my trip to las vegas_RealESR_Gx4_InputR-100_OutputR-75_Blending-Low\frame_000_RealESR_Gx4_InputR-100_OutputR-75_Blending-Low.jpg
