Adding a solid background to a rendered animation
Hi All,
I am Victor Soares from South Africa. I have recently started playing with After Effects CS5.5 having never used footage editing software before.
What I am trying to do is small animation clips for various projects. What I do is do the animation using 3ds max and then I wanted to use after effects to do small manipulations.
One of the things I am trying to get my head around (and this is probably really basic) is the following:
– I render my animation as a series of images in 3dsmax and export as png files
– This saves me a lot of hard drive space as the PNG files are small, but the images do not have a background (only the subject matter is rendered)
– I then stack them in AE and can render them to a .mov clip, however the missing background now just plays as a solid black background
– Is it possible to have the background rendered as invisible?
– If not, is possible to add a solid color background the the .mov clip?Thanks

Yes. If you are rendering to quicktime.mov – animation codec for instance, in your lossless settings you would change your video output for channels to “RGB + Alpha” When it plays back in your quicktime player, it will still have a black background but if you import into a NLE(or back into AE) it will have an alpha channel that maintains your transparency, now you can now place it over video.
If not, is possible to add a solid color background the the .mov clip?“Shift + Y” will will open up the solid settings, pick a color and put it on the bottom of you comp stack.

hey there,
check if there is an option in the 3D program to give the PNG´s a ALPHA-Channel.
if the have, youre fine and it should be no problem 😉
if the PNG´s are without ALPHA-Channel, use a KEY-Effect.
play i little with them and you get there!hope this helps
greetings
