sounds cool. wonder in practice how this will work out with patent encumbered video formats.
Unfortunately, of course, they then want to get paid during playback, but that's the reality for everyone already.
* 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 videos - Overlay text and images - Resize - Create GIFs or convert to a web-friendly MP4 All of this done in your browser, without ever uploading a file to a web server! (* Except Safari, it doesn't support SharedArrayBuffers) A little more: I'…
Very cool! I see that SharedArrayBuffers are enabled again, after they were disable due to spectre!? I have previously tinkered with ffmpeg in the browser and implemented a workaround[1] for the (then) missing pthread support. It turned out quite clunky, but worked.

- First they were disabled due to Spectre. - Chrome reenabled them. - New HTTP headers were added for cross-origin resource partitioning. - FF/Chrome are both requiring those headers (FF now, Chrome next month)
That's awesome that you've played around with this, too. It was quite a bit of fun :)

This is great! Another neat project that comes to mind is https://modfy.video
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 shows a live preview of where you're at in the video.
I want their UI and style haha

It is a really good idea. My #1 question with this type approach was how big the WASM would end up -- 24MB in this case.
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 second time, I moved it to after a file is selected. That gives it time to load while users are presented with options before converting.
It's definitely a trade-off. For us, the choice was easy-ish because we want to keep the budget down as Indie Hackers, so we can't just offer a free tool that costs a ton in backend/serverless charges.

Any plans to support WEBM? Files are even smaller than MP4, which makes them perfect for replacing GIFs
Even our mp4s aren't very well-optimized right now.
If you work with video a bit and think this tool might be helpful to you, let me know!

(This is how I tried to measure FFmpeg binary size, I have no idea if it is correct:
ldd $(which ffmpeg) | egrep -o "/[^ ]+" | \
xargs readlink -f | xargs stat -c '%s' | \
python3 -c 'import sys; print(sum(map(lambda s: int(s.strip(), 10), sys.stdin.read().split())))')
Awesome idea, it is hard to try for now but it could be very useful. I especially like simple clip and resize feature but can't try them right now...
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 place to test the tool at the moment haha
To improve the tool it would be nice to play the part clipped with the sound to check if it's ok. Also the tool failed to load one video.
Good job !
