Ripple effect after using WAX

[SearchQuality]

Hello Forum Members,
I am experimenting with the Rotomate plugin in WAX. The purpose is to have the upper part of the body of an actor flying in the air. I have filmed the background and the moving actor against this background. The two short clips are good quality. Then these two clips are superposed and the rotomate plugin comes between them making the lower part of the actor's body invisible. This is done in WAX without any problems. Well not quite, because in the resulting avi clip the moving actor's body shows ripples like the cutting edge of a saw. This is quite annoying. Has anybody else had this experience? Could somebody help please? Thanks in advance.

Nobody seems to be interested in this problem. This phrase "ripple effect" is also used to describe the event when the user inserts or deletes a video or audio event in the timeline of the linear editing software. In such a case the video events are pushed in a direction like the railway cars of a train. Well in my case I do not mean that. I am trying to find a solution to the phenomenon where moving objects in a video clip are displayed with zigzagged edges sort of waves on the surface of a pool. I hope this explanation will provoke some answers. Thanks.

Maybe you can post a sample clip to illustrate ; I don't have a good idea of what you're trying to say or mean by "zigzag edges" .

Perhaps you can blur the alpha channel to blend it better ?

It could also be interlacing, or bad deinterlacing. As well as some footage, post a mediainfo tree view of the source and new files.

As for the speed of reply, remember that this is a voluntary forum, and most people here have real jobs as well. Sometimes the right person to answer your questions simply can't get the forum as quickly as you might like. Even more so when working with older software like Wax, that has a limited user base to begin with.

Here is a part of the clip and its media info in html format. Worth mentioning that if I do the same thing by cropping lower part of background and upper part of motion and then stacking the two vertically by Avisynth this problem does not show up.

This looks like an inproperly done interlaced resize (it was resized when still interlaced, but not in an interlace aware fashion)

Can you provide more information on the source files ? I suspect if you deinterlace it before using wax, it should turn out ok

Following your advice I deinterlaced the two input dlips using Vdub deinterlace filter. Then I used Wax to apply rotomate effect. The result is perfect. Problem solved. Thanks a lot.
