Is there a way to gradually increase the speed of a video? For example, the video will start at normal sped and then gradually get faster until it's 50% faster.
How does one go about doing a regular speed increase? Sorry for the irrelevance im just starting to figure things out, also interested in a gradual increase
A "normal" speed increase can be achieved by applying the speed effect located in the motion folder in the effect list.
A gradual increase is not yet possible (the speed effect is not keyframeable).
Keyframed speed changes can also be done in Cinelerra (ReframeRT effect), if that happens to work better for you than Blender. Thanks for the tip about Blender, though. Blender isn't very full featured as an NLE, but it actually has a few interesting features that would be nice to have in kdenlive, I'd love to see something along the lines of meta-strips in kdenlive. I just posted a feature suggestion for that in the brainstorming forum.
A crude way to do it in Kdenlive is to split the clip up into a several pieces and adjust the speed in steps.
