Hi everyone,

I'm a professional illustrator and I make often whiteboard animation such as this one :

I'm using KDE but the speed effect is limited to 2000 times, which for timelapse video is not enough. To avoid the problem, by far I'm rendering twice every composition. One time to speed it up 2000 times, and the second to chunk it in several pieces and speed it up again to adjust its lenght to my audio. I have two questions :

1) Is there a way (or is there any future development) to speed up more than 2000 times?

2) Is there a way to get intermediate points within a single video and have two different speed between the two parts?

Thank you
Cheers

Hi,

These kind of operations are not well supported in Kdenlive at the moment (even if there are plans for that in the future).
I recommand looking at this tool for your speed effects (not just slowmo, as the titles seems to imply): http://slowmovideo.granjow.net/index.html

Good luck

Hi Alcinos,

Thank you for your reply and the advice. I took my time and tried Slowmo by Simon Eugster.
Even if the feature description seems to match my needs, the software does not adapt to my workflow. The UI is not intuitive at all, and when loading a new video, sometimes the preview on the upper left corner get stuck with the thumbnail of the previous project...which make it impossible to work. But at least I tried.

Are you one of the Kdenlive developers? Do you know if the two features I described will be implemented in some future version?
Also, do you know how I could donate money to the project to speed up the development? I couldn't find any link on the website.

FFMPEG is also nice

Hi Marcoka,

I tried FFMPEG and it works great! By far it seems to be the best solution to speed-up my video files with command line and then adjust them in Kdenlive to obtain an output file more than 2000 times faster than the original one.

That being said, it would be really helpful to have the possibility to add control point in the middle of a video track and speed up the two part at two different speeds. I always need to adjust an animation to match the voice over, so I need to speed up every chunk with a different ratio.

I hope this feature will be implemented in the future.
