happylinks··on Launch HN: Tella (YC S20) – Collaborative video editing in the browser
Thanks for reporting that! Fixed it :)

Not sure if it was a question for us, but we use Segment and Amplitude mostly for business metrics

Ah yes, this can be a bit confusing. We show you a preview of the screen you are recording, which if it’s the same screen you’re on will cause the looping effect. You can just switch to a different tab and do your video, come back and stop the recording. The 3 second countdown is there to prepare you for the recording starting. We will try to make this less confusing though!

Hey Lakshan! Thanks a lot :) The first beta customers were people in our network from old companies we worked at, we have 2 sales teams which tried us really early on who we knew and also a big remote company tried us because we knew some people there. Besides that we’ve had some YC companies try us, and after that the ProductHunt launch was the first moment we got a lot of new users.

YC for me has been great! We can’t really compare it to “in person” YC but we got a lot of value out of it, they seem to have adapted quite well to the remote world and in some ways I think it’s more practical than before; no 2 hour drive to mountain view for an office hour with a partner. Since we worked at InVision for 2 years we are used to the remote meetings so for us this was kind of a normal way to work I guess. I would definitely recommend YC to people wanting to start their own startup, the amount of information you get in 3 months is crazy.

We have had users make very long recordings with Tella that worked just fine, however we do recommend working in smaller parts. We have a feature called scenes where you can structure your story/video into parts and also record into parts. All of the recording works on the client, so it also depends on your device sometimes; if you have a slow device it can sometimes have issues recording. So to recap, yes there are exceptions where long recordings cause trouble, but overall we’ve seen good results!

We use roomservice.dev which indeed uses JSON CRDT types.

Ohhh I didn’t know that! Your project looks cool! I saw you used popcorn.js, that’s definitely a good way to go. It’s an interesting problem to solve for sure :)

No worries! Html2screen was a very good start, I modified it to support audio recording and got it to a pretty good state in a couple of days. After that the hard thing was just to run it automated on AWS. I used AWS Batch and Step Functions for that. When it’s a bit more stable I’ll definitely write about it and might open source it later. If you want to discuss more, feel free to email me at michiel@tella.tv

Quickly summarized we use puppeteer headfull with docker to do a recording of the video. So you’re right, it’s playing it back, not faster than real time. I might write more about the specifics in the future. It’s mostly open source code, you can start here: https://github.com/Ventricule/html2screen

Thanks for the compliment! We agree that tools like Google Slides, Figma, etc have definitely set the standard for having a "single source of truth". Currently we like being in the browser because everybody can use it, but indeed that has some limitations in terms of recording. Eventually we'll definitely have a native app (maybe Electron) for improved recording, but right now with a 2 person team we're trying to keep it lean :)

Thanks! Here's a couple of examples with Tella's embedded:

That's great! I've made an account already a while ago, but didn't have a lot of time to set it up right yet. Would be cool to talk! (michiel@tella.tv)

Not sure if you were asking about testing purposes specifically. To be honest, we don't have a testing stack yet. I am planning to use https://www.checklyhq.com/ for end to end tests.

I've been using Reason for a couple of years in personal projects and I really like its fast compiler, type system, things like variants, modules. I didn't have OCaml experience before but to me it feels like being able to program in a very mature programming language while still being able to target JS. The community is great as well. Also refactoring code has never been easier in my opinion. That's why I also decided to use it for Tella.

I've used TypeScript a lot in the past as well, and I'm not against it at all. You can do a lot of the things you can do with Reason in TypeScript. But I do have the feeling Reason makes me a lot faster than when I worked with TypeScript.

We released Exporting in Beta last week. This will export to mp4 and send you an email with the link. Still early but results are looking pretty good if I may say so :) In the future we might add a direct integration with YouTube if enough people request it.

Yeah we have had reports from one other user that his Chromebook sometimes has issues recording both webcam and screen at the same time. I definitely intent to test as many devices as possible and put up a more official page about that.

Hey! Thanks for that info, I think I saw some cool demo's of croquet before but will digg into it more. Right now we use roomservice.dev for our real-time video updates which has been great.

Ah I may have spoken too soon then :) We use mux.com for our converting, and they should support (almost) all video files. We currently preview the file while it's uploading. So like I mentioned before, some file formats won't do that initial preview. We will improve this soon so all video files will work equally.

Hey! Right now we don't allow upload of mov files yet, but we will add that soon. Our infrastructure supports it but we can't immediately show a preview (have to wait for it to be converted). Will probably have that within a week. Mp4 files are definitely supported though, let me know if that works for you!

Thanks! We just fixed the links, let me know if it doesn't work :)
