What I want to do is putting in high-pass filter effect on each image constituting a video by using Adobe Premiere Pro 13.1.2.
Premiere Pro has a high-pass filter for audios but it does not have a high-pass filter for videos as far as I can see. Photoshop does.
I also have AfterEffects; the way to use it is welcome as well.
Any idea?
Thanks in advance.
The high pass plugin in Photoshop doesn't exist natively in After Effects or Premiere. The Find Edges tool approximates the kind of effect you're after, but given that it's for a scientific assessment of something, probably won't work for you:
You could try something like the Unsharp Mask in After Effects or Premiere, and then apply it back to the original image using a Difference mode - gives this kind of effect:
If the high pass is what you need, I would export the video as an image sequence, then Automate a Batch in Photoshop to apply it (probably overnight).
What do you consider a high-pass filter for videos if I may ask?
When talking about audio, the high pass filter operates similar to a low-cut, in that it cuts away the lowest frequencies of the audio spectrum and lets the high frequencies pass.
Are you looking for curves? You can adjust the shadows and the highlights of an image (which wouldn't be called high-pass or something similar tho). You can do that using lumetri color. However, comparing to a high-pass, low-cut, low-pass or high-cut, the curves don't actually cut away the brightest or darkest areas, that way you would blow out the highs and crush the blacks, which would result in a fault, not really a stylistic choice but rather actually breaking the image.
If you tell us what you want to achieve with this filter we might be able to tell you the correct name and where to find it.
