3x more frames
Found out a workflow for increasing frames between animations, this was my first test file. Still
requires a lot of manual work but I learned a bit of Flash CS6 Pro and .jsfl scripting so I'd say
that's a win.
[IMG] [Eggplants] Peach x Bowser Doggystyle - High FPS Edit.swf (887.4 KiB)
550x650, Compressed (Deflate). 6 frames, 72 fps (00:00).

Looks pretty nice, the movement is fluid

Looks a little smoother at 72fps compared to 24fps.
Here's the original for comparison: https://eye.swfchan.com/flash.asp?id=127787
I hope Ruffle adds a way to double/triple/quadruple frames between keyframes automatically, it's in
dire need for many older flashes that use flash's default 12fps.
Should be possible to increase it by a number like 10 (turning 10 fps flashes into 100 fps). As
long as ActionScript 1/2 functions or variables divides the current frame to undo the increase it
shouldn't break anything. gotoAndPlay() needs to multiply inserted frame before jumping to that
frame. I assume Ruffle can't just perform its rendering more often per second since there could be
AS stuff controlling the graphics or reading movieclip positions and so on.
I hope someone has already suggested this to Ruffle since it is an obvious feature to me. I'd
imagine in the right-click menu you could select "increase framerate" and then enter a number
1-100, with a desired fps cap (120 suggested, the max in the swf format specifications). And the
embed code could have a target which increases it by default. Going slower would of course be nice
if that's possible.
If the flash player just did that automatically it wouldn't create a bunch of near-duplicate swfs,
and it also seems like your extra frames increased the filesize by 247kb.
