I had this problem with camera automation yesterday when trying to do the following: - I have a full-screen take of a talking person's face and wanted to reduce the size and move the image to the lower right corner when other contents had to appear. - Moving the cursor in the Camera animation only move the image very slightly (maybe 10% of the screen size). - First scaling the Z-axis reduced the image Ok, but still almost no X or Y movement. - Dragging the image on the screen worked, but the X and Y parameters became huge (1000's). And the animation algorithm was completely confused - on play, the image disappeared way out of screen and then reappeared. The position was not exactly the one 'edited'. Any way to accomplish this?

I've downloaded and have working the static version "cinelerra-5.1-ub20.04-20200531.x86_64-static.txz". At this point I have done nothing other than opening and closing the application. Thank you!

Often this problem is due to the wrong limits. Try setting both X and Y between -100 and 100; as in the picture. https://postimg.cc/7JzBs6w7

Thanks Andrea. I checked, and X and Y ranges where at their default values -100 to 100. At those limits, I can maybe pan the image about 100 pixels. I thought that those numbers represented a percentage of the image. At 1024 x 576, 100 pixels are just 10% or so. John
Yes, I confirm what you've noticed, too. You have to check the limits each time and set to the values we need in the project. (I don't think it works as a percentage, but just as pixels with their absolute coordinates).
More experiments: With stay-at-home teaching, I seem to be pressured to dedicate more time to video editing. When I use the Scale-Ratio plugin, I thought I was saved. I could scale down the image, and move it to the right and down. But, it seems that was a day-dream. I could get the thumbnail of the speaker to the right and down, but after rendering shows the image at the top right, though still correctly scaled. Also, of the two places I inserted the scaled clip in my project, one of them seems to drift slowly up (on the screen). It can't be that difficult to produce this effect, can it?
Have you tried the Projector automation? Then you leave the Camera as-is, and use the Projector to scale and position the individual tracks. You can also zoom out to make the image smaller. If an image drifts, then the beginning, intermediate and start positions are not exactly the same, and Cinelerra moves the picture between the two positions. That can be fixed by noting down the positions etc in one of the keyframes, and use those exact values in the other(s). You only have to change at the keyframe positions.

Oops, I did a top-posting, sorry. Keep in mind the X and Y limit values at the bottom. If you want a picture to be able to completely move off the screen (or reverse) you need to set upper and lower limits to what the resolution is. E.g. for 1920x1080, you need a X lower limit of -1920 to be able to move if off screen to the right (with the projector). MatN

John, if gg was doing this, he would use the Projector in the Compositor with the mini-zoom. There is a quick demo at (not a very good one): https://streamable.com/8s3dre Let me know if this does or does not solve the problem. On Thu, Jul 2, 2020 at 12:33 PM John Coppens <[email protected]> wrote:

@John Coppens I didn't understand: after the scale, did you move the box with the Camera movement or did you use "Dst X and Y" (present in scale-ratio plugin)? In this second case it works regularly for me. I had a problem that I don't know if it's related to yours. If I put titles on the top-left side, they stay fixed during playback/render; if I put them on the bottom-right side, they would move (drift up). The title plugin contained numerous keyframes and extended throughout the track (45 min).
