I would have thought there would be a decent PWA that deals with offline files so you don't have to 'upload' them to work with them. It would be awesome to render and export in the cloud without having to do any local heavy lifting.
Anyone know of anything that already exists? Or is this not available for a reason?
Not sure if Chromebook are powerful enough for web based video editing, but I think overall it's a good idea to create this kind of tool.
I actually already thought about that years ago, using GLSL shaders to create visual effects and transitions. One bottleneck would be creating previews of the current editing (precomputing everything so that the preview is realtime and not laggy), Youtube does this by computing the video on their server (not on their clients) and displaying it like a regular video.
There definitely would be some cost to processing in the cloud, but I think it would be worth it.
I just look at apps like Adobe Photoshop CC that can be run on a Chromebook and I'm wondering why it's not being adopted more widely.
Second : A browser can't deal with local files easily
Last: There is probably none free because it is very expensive to edit video files
2: Have you used Google Docs / Other PWAs offline?
3: Yes. Not sure if PWAs have the power to edit locally yet.
