I'm currently experimenting with P&Z of large (Panorama) Images. One issue there is that small features (distant trees, pebbles etc.) produce an annoying flicker when moving the FOV. I found an old post that suggested some blur, and especially to apply it before the panning. I had tried (normal) blur after the pan, which also seems to work. I noticed that applying the blur before is darn slow... The thing is, I don't really understand where this comes from. In principle I should have one image, and from that I cut out different parts. But then there should be no flicker - the pixel values should always be the same for a feature. So obviously the image is rescaled anew for every single frame, and seemingly with different parameters
Nevertheless, some questions: How are you doing this (if at all)? Is there a common sense how to properly get rid of this flicker?
So I just noticed that in ver 0.9.3 there is a new menu item available from the effects in the effect stack - "create region" This is in addition to the Reset Effect, Create Group and Save Effect options that are part of 0.9.2

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!
I am a very new user of Kdenlive, but my searching and googling hasn't come up with this likely-simple answer.
I am publishing a life history of a friend of my family. I have a camera on him, and I want to display photos, while he is still talking... a photo overlay of a video - simple I know. I can't get it to work - unless you have to render your video before you can see the effects work...
Can I also show a box in the corner of of the main screen, displaying other videos, overlayed on the first video. I have seem some examples, but not the method. Please show me how!

My system is running Kdenlive 0.9.2 with Ubuntu 10.04 LTS on a Dell 1420 Inspiron laptop.
I have a rather large JPEG still image (4016x2690) with which I am trying to create a spin animation over several seconds with accelerated rotation in the X axis. Every 5 frames I am adding an increment which is larger by 2 each time, i.e.:
keyframe | Rotate X (Y and Z are always 0 as are the offsets)
00:00:00:00 | 0
00:00:02:00 | 0 (start rotation here...)
00:00:02:05 | 20
00:00:02:10 | 42
00:00:02:15 | 66
00:00:02:20 | 92
00:00:03:00 | 120
etc. (project is HD 1080p 25fps).
After I have added several keyframes like this, Kdenlive will freeze for several seconds and then crash. Always! When I reopen the project in Kdenlive and click Yes to recover auto-saved files, I find that several rotation values are off by 1, whereas they should all be even numbers.
I've installed the latest updates from sunab's kdenlive-svn ppa. As I've read in j-b-m's blog that there is now a new motion tracker feature included I would like to know how to access and use it. I have to admit that while looking around, so far I was unable to find out where it is hidden and how to access it. From the blog entry I could not deduce how to use it... :(
