I am having a problem integrating a video which is without a camera motion. in iclone So as the character in the midle find screenshot is further in the first frame it has to be seen smaller but as He walked near the front it has to be bigger. But no idea how can i achieve this. I was trying to change the scale of the character but changed it to the full sequence. So that option doesn't work out. Is there someone who can give me a tip or suggestion on how to achieve this?

Very tricky to compensate scaling with distance, but doable (at least for a single character - I have not tried multiple).
Basically, character has to walk a "lot" of distance over the small portion of the ground at the texture image.
Shadows cannot be added for obvious reasons.
This is your plane with character walking toward the camera:




The "secret" is to set your texture image for the plane to be perspective (I set this in Photoshop):




Then position camera and set its focal length to get a normal view without much distortion.
Finally rotate and position character so that it walks toward the camera.


Maybe there are other ways, but this is how I made a video clip above (camera is 35mm)...
Side view at the first frame:



Side view at the last frame:



Front view of the plane:






You can also set the character and camera to be parallel to the ground and tilt the plane instead.

I forgot, you may also set the image as Background in Project. The only thing you will not be able to change any angles.
Any changes has to be done with background image itself.

Many thanks for taking the time to reply to me with all this explication. And how about the morph target and changing the height of the character? Is it not easier that way.

Unfortunately, there is no way to scale the character on the timeline. Morphing in iClone does not support bones scaling, thus it's not possible in any way.

Thanks for taking the time to reply to me. So I don't waste the time learning morph creator or morph animator in clone. Is that what you tell me? That it is not going to work.
I highly appreciate your reply. Many thanks!!

It's always good to learn new things
But if your goal is strictly to scale characters with morphs, then the answer is no, it is not going to help.

I "think" I did something similar to what you are trying to do awhile back with a "flat" image. I have wanted "Projection-Mapping" in iClone for some time...
