editly VS ffmpeg.wasm

I found https://github.com/mifi/editly to be an intuitive frontend for this type of task - I used it to create a montage of several clips and was able to easily adjust parameters around timestamps and such to get the montage perfect

Sounds like you already have a process for most of this, but I found https://github.com/mifi/editly to be incredibly helpful to run ffmpeg and make my little time lapse video. Could be useful for others

For example, this declarative video editor lib has JSON configurations for defining an output video:

Maybe this tool helps: https://github.com/mifi/editly

You seem to misunderstand what ffmpeg is for - namely the stream conversion of media. Only limited filters are available. You can write your own shaders and use cli tools like https://github.com/mifi/editly for automation surely

I used Editly to make a clip of several videos with transitions and screenshots. It worked out great with me just editing the json5 file to tweak things

https://github.com/mifi/editly (Node JS)

It's intended to work nicely with Editly, a CLI-based https://github.com/mifi/editly

The way I would do it would be using MoviePy (for Python). You may also have luck with editly (JavaScript). MoviePy has functions to create a TextClip, Images and overlays. It sure is possibly with ffmpeg filters - transparency mixing filters etc. yet you'd get faster results with modules like MoviePy / editly.

Video and Image Processing: Work with industry standard tools like ffmpeg, directly in the browser for fast multimedia processing.

Hi HN! I'm Ivan, the creator of this extension and with it you can now right-click any gif on Google Chrome (desktop) to share it with any of your contacts on WhatsApp Web, you can also use it to upload animated GIFs from your computer, you can even drag-and-drop MP4 files to it and they will be treated as gifs (e.g. they will loop, muted of course). Another nice feature its that it lets you share non-gif images with the same context menu option (e.g. AKA right-click menu)

To create it I had to do a bit of reverse-engineering of the existing JavaScript found at https://web.whatsapp.com/, which is actually a minified React app, I found out that it uses WebSockets to communicate with the backend but thankfully to create this extension I was able to avoid fiddling with those messages. Under the hood it uses the amazing library ffmpeg.wasm (the JS port of ffmpeg): https://github.com/ffmpegwasm/ffmpeg.wasm I also made use of TypeScript, React and Vite to create this extension, using this boilerplate as starting point: https://github.com/Jonghakseo/chrome-extension-boilerplate-r...

Feel free to ask any questions or any feedback you may have about it.

There's already ffmpeg wasm. I've used it in projects. Works great.

There's a low-hanging fruit that I think would make ffmpeg more helpful for regular people.

There's a million terrible websites that offer file conversion services. They're ad-ridden, with god-knows-what privacy/security postures. There's little reason for users to need to upload their files to a third-party when they can do it locally. But getting them to download fiddly technical software is tough - and they're right to mistrust it.

So, there's a WASM version of ffmpeg, already working and hosted at Netlify [1]. It downloads the WASM bundle to your browser and you can run conversions/transformations as you wish, in your browser. Sandboxed and pretty performant too!

If this tool a) was updated regularly b) had a nicer, non-CLI UI for everyday users and c) was available at an easily-Googlable domain name - it would solve all the problems I mentioned above.

As their github page says, based on https://ffmpegwasm.netlify.app ...

I'm guessing no one did GPU-optimizations? I saw a web app (not an ffmpeg transpilation) that went clever and used WebGL so it can access the GPU and use its parallel processing capabilities...

ffmpeg.wasm: The engine making all these happen. However, I’m a bit concerned about its current situation. The repo has not been updated for more than six months now, and that’s not a healthy sign for an open-source project. Clearly I was reading the commits wrong. The author mentioned “speed up x264 with SIMD intrinsics” in their roadmap (https://github.com/ffmpegwasm/ffmpeg.wasm/discussions/415), which, if landed, could make such on-device video editors much more competitive.

I use https://github.com/ffmpegwasm/ffmpeg.wasm and I want my FFMPEG commands to be hidden from others.

Possibly using this? https://github.com/ffmpegwasm/ffmpeg.wasm
