Why it's laggy when is scroll up

[gofortiss]

With the goldengate.mp4 video file it works perfectly, but when i export my own video, it is laggy. My file is only 548Kb.

Do you have an export recommendation ?

In this case, I'd recommend exporting with keyframe distance set to 1, that will solve your upwards scroll issue. The file size will be a bit bigger but it looks like you're starting with a pretty small file.

Thank you for your fast response ! I will check and let you know if it works :)

In my case, it works perfectly!
if somebody needs a command to convert I frame only mp4(video with keyframe distance), please refer to the command below.
ffmpeg -i original.mp4 -c:v libx264 -x264-params keyint=1 original_I.mp4

Any plans to implement the ability to upload two videos (one forward, one reverse), and switch between them depending on which way the user scrolls?

I have a video with very little motion, which is why I would prefer a video with keyframes over the usual image sequence.

No plans in the immediate future, although I'm happy to help review a pull request if someone is interested in implementing it!
