I've been using KDenlive off and on for about two years now and I'm having a new problem. When I add an effect,(greyscale, noise reduction,ect)it used to show up on the clip monitor that I would then use to adjust the effect. Now the effect doesn't show on the clip monitor.The monitor just shows the video clip as if nothing has been added. When I render the clip, it renders the clip with the effect.
So, I've been trying to create a countdown video using 0.9.2. On layer Video 3 I plan to have a background video, then have an imported project on Video 2 that has an empty .png (1920x1080) with the dynamic text effect displaying the timecode. I want the timecode to display in the mm:ss format, so I thought I could use the crop effect to trim off the frames, hours, and minute segnments of the timecode, then just scale and pan it to where I want.
Is KDEnlive currently not capable of applying FX to proxy clips?
I'm running a recent svn build (GMaq's latest svn package under his AV Linux 6) on my now quite old laptop, a 2Ghz core 2 duo w/ 4GB RAM. Despite its less than impressive CPU, I was still hoping I may get away with editing some 1080 mp4 footage and applying some VFX with KDEnlive thanks to its support for proxies although after having tried it I get the impression proxies don't work with effects yet?
It would seem effects can only be applied to the original clips because although proxy clips play fine once rendered, project playback slows to 0.5 fps or so as soon as I apply any effect. I would've expected a machine like mine would struggle applying VFX to 1080 res clips in realtime but I also expect it'd have no probs applying most of the KDEnlives VFX in RT to the 480x270 res MPEG proxy files and hence give a decent project preview framerate.
I'm trying to create a countdown video similar to this (https://www.youtube.com/watch?v=RhN1nTAHTdg) with the time format "mm:ss". I found the countdown generator by going to Project>Generators>Countdown, but the video only seems to countdown in seconds, not minutes, and there doesn't seem to be a way to edit it when I double-click on the file in the project tree.
I have a Kdenlive project with about 5 video tracks. On the topmost track, Video 1, I have a copyright notice that I want to be always present throughout the whole video. It's just a PNG image with alpha transparency, and it contains some text in the bottom right corner.
The problem is that it seems that in the Composite dialog, I have to specify which track it combines with. This means that if that track has nothing in it, or if one of the other tracks is what is showing, then the topmost copyright image disappears. In some cases, the topmost image turns pure white and blocks out all other images. If I select "Auto" it always combines with the second video track, Video 2, so that doesn't help.
It's kind of hard to describe how it doesn't work, so maybe it's easier to describe what I want:
I shot a bird in my backyard. As it flies from tree to tree it becomes difficult to see it because the background is only vegetation. I'd like to "enhance" the bird by making it "brighter" against the background, i.e. by turning the surrounding area "darker". For example, when a TV shots a police chase, the vehicle being followed becomes distinguished (or "brighter") from the others (that become "darker"). Is this possible in Kdenlive? What's the technical term that defines this effect?
