Man, with all of the anti-user "features" of social sharing apps, your interface is a breath of fresh air! I'll be trying out the open source version this weekend so I can share li…

I also took a peak at your code and saw the manifest. This would be a pretty awesome PWA :) I hope you keep at it!

This is awesome! Good job on it :) Wish you had a mailing list signup - I don't want to forget about this! I took a one month Spanish class in Mexico a few years ago. It was amazin…

Yeah, and Spectre/Meltdown haven't helped. There are some pretty crazy security restrictions (no external scripts!) just to get ffmpeg running. I can't imagine the additional secur…

Definitely a performance hit! Probably a combination of the lack of hardware acceleration and running in a JS virtual machine. I haven't checked the exact hit, but that's mostly be…

Sorry for not responding sooner. That sounds like a great use case for us to handle! Although I think ffmpeg in the browser loses some efficiency over the command line. I think we …

Nope! It's all running client-side, so it uses a bit more bandwidth, but there's no way a serverless platform can compete with the cost :) If the tool is popular long term, we migh…

Interesting idea, like append the video to itself but reversed for a clean loop? I like this idea :)

True! When I first started building a video creation app, I was flailing around with google searches to find snippets to use. It was such a relief to spend an hour reading ffmpeg d…

Oh, no, I have nothing there, sorry! haha I'm using ffmpeg.wasm, it's basically ffmpeg compiled for the browser, and it's a simple layer where you basically treat it like the ffmpe…

Emailing you now :)

If you send me an e-mail (andrew@ ), I can dig in a bit more and let you know when I add it :)

Hey, this feedback is great! And it isn't even too difficult to add - we have live clipped playback in our main app. When it failed to load the video, did it show a convert option …

That's awesome! Do you have an example ffmpeg command you run? We're trying to keep this tool super simple for our end users, but I think we might be able to add a webm preset. If …

Seriously! We were trying to build our video editor in the same style (eg like tinypng and GIF optimizers). It's so cool to do it all in the browser! I even built a simple landing …

Yeah. My biggest question when I started building this was whether there was enough in the wasm to support the features we wanted to build. I've been really happy with the results …

Yeah, webm is already built in to ffmpeg, we just had a pretty limited focus for our initial release. Even our mp4s aren't very well-optimized right now. If you work with video a b…

Yeah, that's definitely an issue! We had to "optimize" loading it twice. The first time, I moved it from auto-loading to when the user clicks convert to save on bandwidth. The seco…

Oh that tool is neat, and they have a super slick UI! Our tool definitely isn't as slick, but I think that has its benefits too. Like our trim interface doesn't look as nice, but s…

Yeah, SharedArrayBuffers have been back and forth! - First they were disabled due to Spectre. - Chrome reenabled them. - New HTTP headers were added for cross-origin resource parti…

Sorry if you were having trouble because the website was down. We upgraded the server and it seems to be doing a little better! But also get it if you mean you're not in a good pla…

Thanks! DO made it kind of easy to upgrade the virtual machine haha.

It's up - for now :)

Uggh yes. Which is awesome, but... damn! haha Might need to delete and repost later?

* VM is upgraded - we're back :) * Hi HN, I love new web tech, and was excited to see ffmpeg ported to WebAssembly so decided to build a free tool that uses it to: - Clip/trim vide…
