So, it's been several times I wished I had this option, so I'm going to ask if it's possible to add it in the future - if it's not too inconvenient or against some other reasoning.
I would love to have "Extract M amount" option when extracting faces.
Let's say I have a 30m interview of a person and I want to get a 1k faces out of this interview. Let's say I know the person I need takes 50%-70% of screen time.
So... To avoid extracting the whole 30m video, I need to check the framerate, calculate the amount of frames in the video and divide it by the rough amount of frames I need.
It's not super hard math, but why not let the machine do it?
Why can't I just say "I need 2000 frames extracted". The machine can calculate, which each frame it is.
And then, after I sorted and deleted the faces and got 1200 left - again, why don't I say "I need to extract 1000 faces from the alignments" and again let the machine to calculate that I need every 1.2th face (well, give or take a face or two).
And a somewhat related question - why can't I use a float as N in "Extract Every N"?
I mean I can enter a float in the extraction in the tools->alignment tab.
But it doesn't seem to work as I would expect it to. I think it even broke something (or I have some unrelated bug, or maybe I just need some sleep, but I don't think so). Now I get the same amount of face extracted when I use 1 and 2 for N in "Extract Every N". 3 works as it should though.
Would be convenient if I could just extract every 1.7th face out of the alignments.
I have 10 videos and I want 10k faces out of them since it seems like the easiest way to maximize variety.
One of the videos ends up having 1700 faces in the alignments (and let's say these faces are different enough because it was a long video and I already extracted every 20th frame to get here). I see two sub-optimal choices here. First - extract every 2nd frame and get less that a 1000 faces from this video. Second - extract all of them and delete 700 faces by hand. Well, there's a third option too - have 700 extra faces what brings me over the 10k faces (and I remember 1k to 10k was the recommended amount somewhere in the guides).
