Any chance this will become open source? Would love to take a deeper look into it. Looks great though! And something that can use animated webp and do conversions! +BugReport - Dragging multiple webps to add, just adds eg. 5 of the first img in dif rows. (Not tested other formats)

At the moment I don't have plans to make it open source. I suspect that the drag and drop limit of 5 may be a browser/OS limitation, now I couldn't reproduce this but will look out for it. And yes, probably it would make more sense to put them on the same track after each other so I will change that. Thanks for pointing this out!

Ah I meant, if I drag [n] images at once, eg. cat.jpg, dog.jpg and fish.jpg -- Three fish.jpgs are inserted (Chrome 96). Cheers for the reply, and again, the work looks great :)

What's wrong with Firefox, why does it have limited features?

It doesn't have WebCodecs: https://caniuse.com/?search=videodecoder

The app seem to be working fine to me on Firefox. Which feature not available on Firefox? I just did some basic editing in Firefox and all features I tried (haven't tried them all) seem working. Even motion tracking works.

The biggest problem is not supporting h264 encoding for the output.

Also as the preview playback is done with html video elements and those can't be started at a precise enough time, the timing of these videos are imprecise and may not align with other elements. This only happens at playback or scrubbing, not when staying on a single frame and the exported result should not be affected.
