Show HN: Open-source AI video editor
Hey HN community! I'm one of the lead devs of this project at
fal.ai and we created an open source lightweight video editor
powered by the latest media AI models. The main goal was to tackle
some challenges when dealing with complex media handling and
encoding on the browser. It all started as an internal experiment
but as we tackled some of the issues it was clear there could be
some value sharing it with the open source community. Some of the
key points and tech stack details: - It uses IndexedDb, so all
data is local (i.e. no auth, no cloud db) - Multiple AI models for
video, image, music and voice-over. APIs are provided by fal.ai -
Built with the typical React+Next.js, Shadcn front-end - Used
remotion.dev for the realtime video preview (this is such a great
project, without it the codebase would be twice as large) - File
uploads so you can bring your own media by uploadthing.com -
ffmpeg for encoding the final video and also some ui tricks, like
the audio waveform We deployed a version of it and for now it's
free to use. We do plan to add some rate limiting and a bring your
own API Key next, but it's open source and I'm curious about what
the community will build on top of it, or derive from it. Customize
your own video app and if you do, please share. If you have any
questions, hit me up!

| A small bug report: if you have both a still image and a video in
| the timeline, the video does not play in the preview.

| Nice.

| Fal wants to sell compute, and since they're straggling behind
| the compute-as-an-API leaders they've attached their cart to
| the art, image, and video subset of the market.
|
| They think they've got a leg up on their model partners. That
| the foundation model companies will mostly become generic
| copies of one another, servants of the compute layer. There are
| so many foundation video models now, and they'll battle it out
| over dwindling margins. Pika, Runway, Kling - they're all the
| same. And there's also growing open source foundation models.
|
| The thing that stands in Fal's way is that the future of AI
| video for artists is local. Hunyuan and Comfy can run on
| desktop machines, and real artists hate the SaaS model and non
| local stuff. It doesn't look like we'll even need A100s to
| reach Pixar levels of quality.
|
| The ones to watch in the art space are Comfy and Invoke. And
| Adobe.
|
| Fal probably has a future in powering the API-driven YouTube
| Shorts slop, though there's probably an upper limit to the
| number of talking head startups.
|
| But there's no way they win artists over to cloud.
| Sophisticated tools are going to be local. Any SaaS art tools
| that do achieve escape velocity will buy and manage their own
| compute and won't go through Fal as a reseller.

|
| Anyone can replace the AI layer with their own local models,
| other services... whatever suits your use case and preferences
| is fair game.

| Thank you for open sourcing the project, the UI looks fantastic.
| I noticed that several comments have mentioned the potential to
| improve functionality by allowing users to replace the backend
| with local models, such as Hunyuan. Would you be open to
| considering this feature in the future? Additionally, if other
| developers were to contribute, do you think this could be a
| possibility?
| drochetti wrote:
| Absolutely. The idea of being open source with a permissive
| license is that we're encouraging anyone to do whatever fits
| their use case.
|
| You can replace anything, deploy on your own server, port it to
| other stacks... whatever brings value to you.
|
| We're also open to PRs, cut an issue in the repo and we can get
| the conversation going.

| Great release , where is the source code for FFMPEG library used?

| Cool, I'd love to see more slop on YouTube.
