[Feature request] Denoise sample generation

[Bukethead]

Is your feature request related to a problem? Please describe. An annoyance more than a problem, my feature request would save time, I have rendered whole videos at the improper denoise level and either need to reduce or increase it, re-upscaling the same video entirely with different denoise settings wastes time.

Describe the solution you'd like Have the option to generate samples (short clips, possibly at different durations of the video) at each denoise level so the user can select the best level based on each instance of upscaling on a per video basis.

Right now software already has "video sampling" feature in the "additional settings" Tab, for now you can try that feature (I know that's not the exact same feature you requested)

In the meantime I suggest you just use ffmpeg to cut out a short clip from your video file. It works perfectly for me, the command I use for example is:

ffmpeg -i "C:\Path\To\Movie\movie.mp4" -ss 00:00:00 -to 00:00:10 -c:v copy -c:a copy NameOfFile.mp4

In the example above ffmpeg would create a clip from the very start of the movie to 10 seconds.

Let's say you have a movie called Turtles.mp4 which is located in D:\Movies and you want to have a 20 seconds clip from the 00:30:00 to 00:30:20 you would change the command to:

ffmpeg -i "D:\Movies\Turtles.mp4" -ss 00:30:00 -to 00:30:20 -c:v copy -c:a copy TurtlesClip.mp4
