Hi wwwmaze,
I don't have these lines as I'm probably using a different (optimized) version from a dev. The corresponding code looks like this:
Code:
dw = (project_w*z)&-2;
dh = (project_h*z)&-2;
Anyway. If I remove those lines the preset stops working. If I remove the &-2 it stops jumping back as you suggested. (I already guessed it could have something to do with rounding but was of course to stupid to see it in the code.
)
For me this was a serious drawback in the whole concept of video/image editing as it makes it nearly impossible to do simplest tasks. And I was just wondering why I never discovered it before.
This is what it looks like now:
The jumps are gone. But I'm not sure if those steps are right. And in rluka's example you can see in the beginning that the movement seems to be smooth while the zooming makes kind of stepped progression. This looks weird. I will make further tests.
Many thanks for your help.
BTW: rluka, I actually can't listen to your mix with my studio headphones as they are broken. For me it sound great over Bluetooth.
