Hasta La Motion!

Is it possible, in AE, to apply an effect only to the area covered by a mask, just like you could in Shake, for example, attach a mask to an effect node?

Also, how can I have a layer with single mask of multiple shapes, or to have multiple masks adding up, instead of Mask 2 acting only inside Mask 1, etc? Do I necessarily have to duplicate layers?

Im using a red one with a 20mm lens to shoot a tracking shot for myself and am running into a big problem with my understanding of film backs and crop factors for sensors.

Say I shoot my footage at HD using my red. From what I understand the camera is essentially cropping the sensor to compensate for this. So if I want to enter my focal length into pf track, is it still 20mm (the focal length I used), or has the focal length changed since the sensor has been cropped?

Thanks in advance.

hi,

i am actually trying fusion as compositing software ( so i am kinda a newbie)

i was just trying to merge several pics between them just for testing, i choose one of my vehicle render, it appear well in the assigned viewer, then pick a random background from a stock in DA, save it, create an other reader, import the pic and put it in the second one, and it appear like the attached pic, it looks twisted in the viewer, i try to tweak the pic , save in TGA, PSD in photoshop, nothing works.

i tryed to look at pixel ratio, square, the background get the same aspect ratio of my working vehicle pic, i tryed to tweak the import settings, do not work…

i tryed with several pics, some of them works, some do the same , and gets like this,

so the question, did i forget to tweak something or turn on an option?
or maybe a picture protection? i am trying nuke too, and the pic is nicely imported, no distortions…

thanks

Hi all,
I have an age old question: (well for me anyway)
I have a HD Canon that records @ 1440 X 1080 1.33

What’s the difference if I render a video @ 1920 x 1080 aspect square, or…1440 X 1080 aspect 1.333 ???

When I observe them up close, they look the same.
If there are 1,920 pixels by 1,080 pixels in a given area. And those pixels are square in shape, is that better than 1,440 pixels by 1,080 pixels in a given area that are enlongated or stretched?

My instinct is to say, the more pixels the better, however, if you think about pictures, if you took a 720 x 480 picture, then rendered it at 1920 x 1080, do you now have a HD image?…No you don’t and the image would be pixelated to boot.

So my question is:
If the native video format of the HDCanon is 1440 x 1080 1.333, what gives the BEST resolution, 1920 x 1080 square, or 1440 x 1080 1.33 when rendering it out of nuke, After effects, etc..???

Thanks,
Lou
