Midi controller VS Output resolution
Posted: Tue Apr 17, 2012 12:43
Hye everybodie,
i started to work few days ago on a project for a friend of mind : i want to use a midi controller to move videos
(control the x and y positions).
But i get some troubles, here is what happens :
i assigned my midi controller on CC to the position x (cc42) and y (cc43) , using absolute mode. When i move my controller, i've got this range [-16384;16384] for x and y positions.
So i started to make it work with this range. so i needed to change my clips widht/height to 16384 and put a 200% scale in order to get my video on place. Then, my video and controller ranges are equal, and the result is here. But i can only play that on the 640*480 output window... so i just view a piece (640*480) of my monstruous (32000*32000) clip.
After that, i was looking for unscale this result in order to play it fullfill on my output screen
I tried many things to fix this problem :
- reduce the composition scale value : affects only output resolution, not my clip resolution.
- reduce the layer scale value : cancel the scale value of my clip
- change the midi mode (absolute, relative...) : i tried a lot of possibilities but it just affects my positions range and this range is unstable, the only mode which stay stable is absolute mode.
- use an effect like keystone on clip/layer/composition : the effect works on the same way than the scale
nothing works until now...
So i don't know if i have to insist on resolume parameters (if you get an idea) or if i need to concentrate my self on my midi controler in order to reduce this [-16384;16384] range. Actually i think that resolume solution will be easier... But i'm maybe wrong...
Thanks for your help and sorry for my frenchy english ^^
(PS : if u need pictures to illustrate my problem, tell me and i will upload this... thanks)
