Thank you for the responses - all very much appreciated. For reference, I am using a Win 10 system, version 7.25 of VideoPad using an onboard graphics card on a fast system. Performance should be very good in terms of the interface. The vanishing image inside the container is a quite consistent bug. An inconsistent bug is the container becoming unresponsive to mouse control, which is released by entering changing a value using the sliders. When I snapshot the sequence the smaller image is also missing despite being visible in the sequence. I suspect that the performance hit when using the WYSIWYG interface is due to the effect changes being tied to the track preview which seems to take a long time to update. I have tried the Borate's solution and was unable to replicate with my square smaller image. Borate's smaller image seemed to be more rectangular than square. The result I saw was that there was movement in the middle of the screen but the image was clipped left and right as if constrained by an invisible square. Moving the image beyond the bounds of the visible clip preview area had no effect on this. The only resolution that I have found that is effective is: Letterbox to aspect ratio (same effect as generating an image with the same AR and importing that) Motion (far right to far left - properly keyframed) I take the view that having to messing around with the object's AR before applying the Motion effect is also a bug. The auto scaling of the smaller image so that the smaller image width = the video width (height is therefore taller than the videos height) is more of a feature than a bug, but since that generates the "Letterbox to aspect ratio being required" issue, I think that this is also a bug. I have previously tried Nat's Scale / Position but again find that this results in the clipping effect. Is there a bug reporting route? I don't think that this is wholly down to my lack of familiarity with this product since we are arriving at the similar solutions.

Another "work-aound" for my case is to apply the letterbox 16:9 ratio. The image is invisible in the clip preview when applying the motion filter but visible in the sequence preview once placed. I get a feeling that the effects interface is very buggy.

You have to scale down via Motion or Scale. I don't see any options that tell the software not to scale up to fill the screen on placing an image.

Here is a video example showing a 256x256 image of a fish moving right to left. The top fish is 256x256. The lower fish is 391x218 (16:9) ratio more or less. The video is 1920x1080. The fish has also suffered in terms of image quality. https://youtu.be/ziD8nuZv-1Y

I can also circumvent the problem by increasing the canvas size of the small image so it has 16:9 proportions. When I place the image new overlay track it now at least is the same size as the video frame and Motion works as expected. Surely I am not require to change the aspect ratio of every image that use to that of the video?

This is the problem: I overlay a small square image and scale down place it far bottom right using Motion (same effect with Scale then Position). I move the small image from far right to the far left and everything looks fine in the clip preview the right left panning is as it should be. I look in the sequence preview and the movement is clipped about two thirds of the way to the far left hand side so the image in effect vanishes. In the clip preview when showing the background, the small image is oversized and extends way beyond the rectangular background image. Is this a bug? An aspect ratio issue? Am I missing something? I am able to resolve the issue by generating a new image the same size as a single frame and moving that instead, but there are major interface performance issues related to that approach. Any ideas? Thanks, Bill
