I believe this is fixed but can't test on my end. Anyone using old version of Safari that doesn't support MediaRecorder (or disabled MediaRecorder), please load the app and let me know if it goes blank.

Bizarre... what is your device/os?

I'm seeing it work fine on Safari on iPad 14.4.2 and Big Sur on an MBP, but I get a blank black screen on another Mac running Mojave.

macbook pro, macOS.

    Error: Media Recorder API is not available in debug.ts

and nothing ends up rendering, all divs are empty.

(editing to add, since I can't reply to the child for some reason):

Mojave, safari 14.1

Wow. Thx for finding this. I'll get on it. Which version of macOS?

ah, it finally let me respond to this comment, sometimes hn is sooo weird :)

safari 14.1 in Mojave. I spend too much time with weird audio stuff to move past Mojave on this laptop unfortunately.

edit:

aha -> looks like you have to turn on the experimental features to get it to work. might be good to have a note for someone who doesn't have that turned on to avoid the black screen.

Been looking into it. Looks like it's an old safari issue related to Media Recorder (for downloading your sequence.) I'll play around to make sure the ux is right regarding this bug.

It works fine for me:

Safari Version 14.0.2 (16610.3.7.1.9)

MacOS Big Sur 11.1

2021 iMac (8-Core Intel Core i7 3.8 GHz)

Respect on the amazing response time for this issue.

Thx, it’s my baby, I want it to work ::sweating:: (I think that bug is fixed)
