Odd behavior when passing -factor as command line argument #237

Open Michaelvirga opened 1 year ago

Michaelvirga commented 1 year ago

I'm observing very inconsistent results when passing different values for -factor in the command line argument.

C:\Users\xxx>"C:\Users\xxx\AppData\Local\Flowframes\Flowframes.exe" "C:\Users\xxx\Image Environments\video_15_fps.mp4" -factor=8 -start -quit-when-done -ai=0 -output-mode=0 -model=0

When passing factor=8, it will actually set the x factor to 4. When I pass factor=4, it will set the x factor to 3. When I pass factor=3, it will set x to 2. When I pass factor as 6, it sets x factor to 2. Is there any consistency to this or intention behind why it's setting the x factor to different values other than what was actually passed in factor?

Full observation list:

2 = 2 3 = 2 4 = 3 5 = 2 6 = 2 7 = 2 8 = 4 9 = 2 10 = 2

Is it based off FPS or something else which I'm missing?

Basically I am going off of this documentation (only that exists) on how to pass CLI arguments: https://github.com/n00mkrad/flowframes/issues/67

Sorry if this is not officially supported, it's just so close to being a massive efficiency increase in my workflow, it would be great if the CLI was a bit more robust and documented! Really powerful tool.

The factor is index-based I think and will not work properly with custom numbers, I'll need to update the CLI code. I'll take a look soon.

@n00mkrad Much appreciated, I can get by with 4x being the max (passing 8), but for higher frame interpolation would be cool! No rush on it either.

Could it be that you're parsing the factor argument as a float? All of the other index-based arguments seem to be parsed as integers (see line 167):

This is still an issue for me =( No matter what factor I use it does 2x
