Create motion tween

I am trying to use 3ds max as follows to create a scene with some predefined animations.

I create a scene add some background , houses trees etc.
I output this an image for my background.
I place a character in the scene with some animation.
I then mask out all the objects in 3ds and export the just character animation as a series of transparent gifs.
The first issue is the gifs have a white back ground. Is there a mac app to bulk auto crop and replace the white with transparency.

Once I have the animated gifs how do I implement this into corona. I tried using a sprite sheet but realised this only works in the animation is loopable ie walking dancing. My animation is walking from the rear of the scene to the front over an uneven surface.

I am trying start the animation on clicking the character and have him appear to walk along the path from rear to front.

Once this works I can then create some pre-defined animations that I can call as needed.

Hope this makes sense.
Cheers

This isn’t true, the animation doesn’t have to loop. However, the animations should be short and it sounds like yours is a long sequence. Assuming you need to render out the entire sequence and play the rendered images (depending on what you’re up to, you could do this as a looping “walking towards the camera” animation and transition the scale to make it look like the character is walking forwards) then what you’ll want to do is play a video of your render:
