I am trying to do a simple pan and zoom on a still picture (jpg). I have the pan zoom effect setup how I want it, and when I play it in Kdenlive, it looks great. I then render the project, and the pan zoom is something totally different! I am using Kdenlive version 0.9.2 in Ubuntu 12.04 with all installed packages up to date.

The P/Z effect is somewhat confusing for me to figure out, and now even more so because the render does not match the preview within Kdenlive!

Watch http://youtu.be/C60BqWg4ljg to see what I'm talking about.

Any ideas on how to make the final render work as it is supposed to?

I tried to reproduce your issue. But I could not. Results and how I did it demoed at http://www.youtube.com/watch?v=0aSe1y6e4RE

I have two key frames in the pan and zoom. One at the begining and one at the end. My size was 25% at the start key frame and 100% at the end. And I centered the images on the screen at both keyframes.

The preview and the render appear the same.
Your way of doing it might be different to what I did.

The other difference might be I am using 0.9.3 from https://launchpad.net/~sunab/+archive/kdenlive-svn

Thanks for the video. I appreciate that. I appears I was doing it the same as you were, but who knows. I had been playing with P/Z for a while just trying to learn it, and then noticed each render was looking the same. I may have confused Kdenlive. It does have some strange quirks. Later today when I get a chance I'll start a new project and try again and see if that makes a difference.

I may also update to the latest version. That sometimes makes a big difference depending on what bugs, etc were fixed.

Just now got a chance to play with this again.. wouldn't you know, I started a new project, imported a .jpg, and setup the P/Z stuff again. This time the render matches the preview. Who knows.. guess it's one of those Kdenlive quirks.

Thank again for your input, ttguy.
