hmm yeah you will probably get black screen when its still loading, it is pretty big because of ffmpeg, probably about 50-80mb to load, ive noticed it myself but its usually couple of seconds, thats error on my end because im handling that loading not right because it should show loading indicator but its not ... but it wont work on mobile anyways, i need to fix problem with drag and drop because its simply not worki…

Ah yep! I just didn't wait long enough. Very cool. Seems like it took a lot of work. And it seems better than other browser-based video editors I've seen in the past, so kudos. TIL about the webcodecs API to get frames of video and chunks of audio: https://caniuse.com/?search=webcodecs https://developer.chrome.com/docs/web-platform/best-practice...

yeah sorry for that long loading and not properly showing indicator, it took long time for me to develop especially because I was trying to learn as much so I usually tried doing something myself for weeks and then finally thinking that was idiot move and using library, webcodecs API is super cool, im hoping they will also add muxing and demuxing to api, though I like ffmpeg because im using it more than just muxing and demuxing in this project

yep webcodecs api is not supported in firefox .. any non based chromium browsers

Firefox supports the WebCodecs API behind a feature flag. Set dom.media.webcodecs.enabled to true. I am able to use your app this way -- the media import, timeline, and player functionality seems to work fine.

good to know, hopefully they will add it soon to work without flags

That’s funny - I created one as well, but it took me a bit longer. It’s not as full featured as yours in the non linear editing sense, but it’s for a different use case

I’m trying to launch it on Show HN right now but not having your success :-(

It was hard as shit to build. mine is commercial

You can see my editor in action here:

https://www.demo.fun/d/lSVixyJOZeZ1ugT

It’s specialized for its use case—editing product demos, but, I had to virtualize the timeline events to support cutting and nested cuts. In other words, when a cut in placed in the video, I jump to the point in time at the end of the cut and adjust all surrounding events.

It doesn’t do join and split, but I would know how to do that.

Also lots of FFmpeg stuff on AWS Lambda

Love to chat sometime about what you learned! Yours is very impressive!

For anyone wondering why you are getting black screen, sorry for that, I completely forgot about handling it correctly, mine project was already cached so i forgot about this problem, basically you need to wait until it loads about 50-80mb PS: thanks to anyone for giving me github stars :)

If i was you, i would at least say zenkyu for the github stars, but i guess thanks is fine too...

thanks im glad you think its impressive it means a lot for me after working on it so hard for so long and after endless destroyed sleeping schedules ... I did learn a lot about the tools like ffmpeg or mp4boxjs, and general idea about video processing and codecs to make it work .. in other words tons of different things to learn to pull it off, but thats what I wanted :D I needed to challenge myself because im not confident in my abilities as programmer so hearing some nice words about my project is all I need now

Hey this is awesome! I'd love to hear more about some big issues you had, and how you solved them. For example, you mentioned using the webcodecs API for quick rendering. What do you mean by that? What was the slower alternative? Also when did you choose ffmpeg Vs webcodecs API and what were the differences? A lot questions, sorry just really impressed!

I love that it's 100% client side. I tried to drag and drop a .PNG but it didn't work.

ooh theres that super confusing bug .. well another bug that im finding out about too late ..., if you tried to drag and drop file from explorer to the website then it wont work, but in the same time it will show that drop indicator which is confusing, I completely forgot to implement the importing on drop and in the same time I didnt remove that indicator, well stupid me, honestly I havent got many people to test it so it is what it is ;/
