Speed of animation changing after converting to timeline
Hi,
I've been using photoshop for several months now and I'm having one recurring problem which is beginning to annoy me more and more and I'd greatly appreciate if someone can help.
I make gifs of popular TV shows and movies, to upload onto socail media (mostly tumblr and twitter). My process is: import video frames to layers > resize image > set frame delay to desired speed of gif > convert to video timeline > convert to smart filters > sharpen/blur/adjustment layers until I have the desired look > export > save for web
The problem I'm having is this: when I convert to video timeline, the speed increases dramatically. I spent hours yesterday and today googling and searching forums for a solution to this, but I haven't found this exact question be asked before. I've tried adjusting the frame rate but somehow this doesn't help, the gif is just as fast as before.
I've uploaded my gifs to show you what i mean.
Here what my gif looks like after I've imported the images, resized the image to 268px (cos that's tumblr's setting), and I've set the frame delay to 0.07:

Then when I click "convert to video timeline":

As you can see it's a lot faster, and I literally haven't done anything else, all I've done is converted to video timeline.
This is when I tried to reduce the frame rate from 30fps to 20fps

I do have 2 work-arounds to this - 1) When I'm in video timeline and I've finished with adjustment layers and stuff, and I'm happy with how the gif looks, I go ahead and export as a gif. Then I open that same gif I just saved back into photoshop. In the frame animation window I set frame delay until I have desired speed, and then I save for web again. Alternatively 2) Before I save for web, I flatten frames to clips > convert back to frame animation > make frames from layers, then set frame delay again until I have my desired speed. Then I export for web.
So I know how to manage the issue, I Still know how to get to my desired outcome. The problem is just that I’m sure there’s something in my settings that’s wrong but I can’t figure out what. I’ve asked around other gif-makers on tumblr and they all seem to not know what I’m talking about so I think this isn’t something that is fixed within photoshop; I think it’s just a problem with my specific photoshop.
For reference, I have adobe photoshop 2020 21.0.2 and a macOS high sierra from 2017.
Any help would be greatly appreciated.
