Description rafamar.mm.ig 2019-05-29 20:06:18 UTC
SUMMARY
The first keyframe of the effects can not be moved, this was very useful for inverting animations, but now it is impossible to move the first keyframe.

STEPS TO REPRODUCE

We had a lot of crashes due to not have a keyframe as default on the beginning of an effect. Why you can't inverting animaitons anymore due to this keyframe?

I imagined it was for dating, but it would not be better to forget about a keyframe as default, if you do not need to animate, so there has to be a frame, and if you have to cheer up, I'm sorry I can not move it. What I just said is like this in all the applications I work with, Premiere, Sony Vegas, After effects, Blender, Maya, Combustion, Particle illusion ... etc, if you do not have to animate, there are no keyframes, when we animate the insert ... this concept if you can integrate it would be a breakthrough in kdenlive.

Why can not I invest an animation? because simply because I can not move the keyframe, since a very usual technique to animate an input and an output of an object, whatever it is, is to make the input as a clip the development another and the output is not more than the same clip of the entrance where the keyframe of the beginning has been taken to the end and the one of the end to the beginning. Look at the image that I have attached.

Comment 4 rafamar.mm.ig 2019-06-05 12:06:58 UTC
Another option would be to copy the values of a keyframe to be able to paste it into another. This would also be a good step forward.

It would also be very correct that when there is no animation there are no keyframes and these can be created when they are needed. This would be the most similar to how other applications work.

I do not understand programming, if I knew I would try to help with code, but I do not know. I am an audiovisual technician specialized in 3D and FX and I teach and I am betting on free applications in one of the subjects.

Copying of keyframes to other keyframes is possible
First keyframe is required by MLT
