Whats the problem?
I saw the video but dont have audio on this laptop. (broken speakers)
As you can see in the video the mask tool acts strange after working on a project for a while.
I always choose the effect first and set a positioned mask before making any parameter adjustments.
Because I set and position it first...I have never seen that behaviour when its dragged around as you did.
You may need to set the spread and opacity parameters if you are trying to soften and feather it better, There is an inside and an outside option on the :stick"
But the whole point is that I am not able to place the mask properly because of the strange way it behaving. The purpose of a mask is that it should affect the area it is located above and not somewhere else, and it should also fill the entire mask and not only a spot at the center of the mask area.
It has nothing to do with the order of things, or if I turn up feathering or extract the edge. It's all about the wired way it applys it self.
If I apply and drag the mask to the corner, it should affect the corner and not somewhere near the center of my footage. As it is right now I have to zoom out to 25% and drag the mask way out of frame to affect the corner of my footage.
Check your graphic card drivers are the latest maybe.
FWIW - I dont have that issue ( Windows PC, Nvidia graphics card).
I do a lot of masking for vignettes, CC and grade. ( Masks - A favourite feature of mine in PPro
If you're trying to make a vignette, have you tried inverting the effect? That way instead of a circle in the middle, you get the corners of image darkened.
Just a thought. I do see that the effect is still acting strangely, not sure why.
Thanks for making the video. That must be very frustrating. Do let us know if you find a solution.
strange, i did see someone with a similar problem in speedgrade. i think one of the adobe video's said they ported some of the tech from speedgrade into premiere for its engine upgrade... does this happen with all masks? you can make the vignette using RGB color corrector, Levels, luma corrector, luma curve, fast color corrector, or three way color corrector effects if they aren't bugged.
It seems that the problem occurs when I use adjustment layers. When I apply the mask directly on the footage, it seems to work fine, from the few tests I've made so far. Am I the only one with that problem?
playing around with some projects i have, just by chance i had re-used an old adjustment layer at 1080p for a 720p sequence. when applying the mask to this adjustment layer it did exactly the same thing as yours in your video! so check your adjustment layer, is it the right size for the sequence?
With a name like that, had to check out your site ... nice work, in that spare Scandinavian aesthetic. Especially liked the frokost soup ... got the full recipe for that? ... Um, off-topic but there it is! (Min familie er Norsk)
As to topic, RoninEdits has a good question ...
