We have tools for generating AI voiceovers and are working on human voice-over support. So yes, soon you'll be able to do this.

Show HN: Open Session, the open-source cloud agent-orchestrator

https://www.opensession.com

Open Session is an open-source cloud-based agent orchestrator. Self-host and use it with any model you like (or all of them).Open Session started as an internal app at Tella (YC S20). It’s become our most important tool. The whole team uses it, and not just for product development. It’s also great for customer support, operations, and data analysis.In the last couple months we turned it into...

What approach did you settle with for your exports?

The next main thing will be improvements to the timeline. We want editing on Tella's timeline to feel much more approachable than "traditional" timelines.

We'd love to help educators more, and we've had a few make mini-lessons and tutorials already. I'll send you an email.
- We don't have this. But we have been thinking about a more dedicated recording "mode". However, because we're in the browser we have some limits on what you could annotate. Inside of Tella would probably be fine, but outside of Tella would be tricky (e.g. you're recording another window).

- We support exporting to mp4. So you'll get version of the video that you can distribute (beyond just sharing the link to Tella). We don't have plans on a slides-only export though.

- We use ReasonML, Mux (for video), and Roomservice.dev (for the real-time component).

Thanks for the kind words!

1. ReasonML, ReasonReact, Mux, roomservice.dev.

2. Exporting our web "video" to .mp4, and keeping media in sync.

3. Better timeline & canvas editing features (plus some organisation features, for people with lots of videos)

4. Loom, mmhmm (at least for the non-live aspect), and slide decks.

Yeah the demo doesn't illustrate the MediaSync aspect very well. But if you give the product a go you ought to get a sense of what we described in the implementation part of the write-up.
It sounds like Tella could help with at least some of that already. We definitely don't have everything you'd find in a desktop editor yet, but it's the plan to have more!
Tella is free during beta (which will likely be for a few more months). We'll introduce paid individual and team plans after that (and keep a free tier). However, we don't have figures on the pricing we can share yet.
Ugh, good catch on the typo. Fixed.

"But the demo video doesn't look like much beyond a web based PPT tool. I'm struggling to see why I would use that over a generic tool like Google Docs."

Appreciate this observation. For people who've not done much video editing before we want Tella to feel as familiar as possible (e.g. editing a slide deck). Equally, we'd eventually like people who do know their way around a video editor to feel like they can create what they want in Tella.

Awesome. Tella should be fine on Chromebooks, but we have an issue with the performance of recording in the past. If anything comes up drop us a line on livechat.
Not yet, I'm afraid... we'll be free while we're in beta (which could easily be a couple more months). From there we'll keep a free tier, and introduce paid individual plans and a team plan.
We've seen people make tutorials and how-tos already, so you should be able to put together a course.

Launch HN: Tella (YC S20) – Collaborative video editing in the browser

Tella (https://www.tella.tv/) is a collaborative online video editor for screen and camera recordings. We're making video creation accessible to people who have no prior editing experience.Sharing screen and camera recordings is a rapidly growing way for people to communicate at work, especially in technology where the subject matter is often on screens (new features, code, designs). But while...
