Change sequence frame size without layer position auto-adjusting?

[CK_KoopaTroopa]

Hello! I've been using Premier Pro on and off for about a year now, and I'm encountering an increasingly annoying bug (or "feature") - if I create a sequence and have animations on the position of clips in said sequence, if I realize I need to change the frame size the position tries to auto-adjust with the ratio of the previous size!

For example, let's say I make a sequence 1080x700. I start an animation on the position of a clip: I want it to move down the screen over an interval of time from (540, 200) to (540, 600). I then realize I actually need it to go all the way down to y=800, so I change the frame size to 1080x900. I go to edit the animation, but now the 200 shows up as 257.1 and when I change it to 800 it resets itself to 1028.6 (multiplies whatever value is in the y by 900/700)! At least I think that's what it's doing...

And then it shows up in that new position on the screen and I can't figure out how to make it realize the new frame size without either doing the math and tricking it into the position I want or starting the sequence over from scratch at the new size upon creation, neither of which should be necessary! Anyone know how to fix this or if it's a known bug?

you can use the 'Transform Effect' instead of keyframing 'Motion'

but i don't really know why you want to change the sequence frame size ? you should have a fixed

frame size and adjust the keyframes accordingly...

anyway, I reproduced your problem, using the 'Transform Effect' will not default values when

frame size is changed. Because 'Motion' seems defaults to values related to sequence frame size

while the Transform Effect keeps the same values when the frame size is changed.

Interesting... Is that the one under Effects > Video Effects > Distort > Transform?

I'm working with animations with transparent backgrounds as a separate sequence to be overlayed on the main video, so the frame size is smaller than the main video to save any unnecessary memory (and be more organized) but how MUCH smaller can change if I put something in the animation that's bigger than the frame size I thought would be good. You could argue that I should be doing all this in After Effects, but I'd rather not open up a whole other program only to have my work not link directly with Premiere Pro if it can do the exact same thing.

you can use Dynamic Link or the new Motion Graphics Templates (mogrt)

you can still do it on Premiere Pro if you prefer so, you have many options
