Show HN: App to help with planning, producing, reviewing, and publishing video

Hey everyone, I've started working on an app to help companies, freelancers, and even individual content creators plan, produce, review, and publish their videos and streams in a more organised way. We're just getting started so not trying to sell anything at this point, but I do need feedback on where we're headed.

I recorded a video walkthrough of some mock-ups at https://www.youtube.com/watch?v=mTtB_EkUA-M, or you can take a look at them yourself at https://www.synura.com/mockups/ (it is somewhat self-explanatory, but in the video I add more context). You can think of it as a potentially better, more organised alternative to having a bunch of stuff in random Google Docs and other places that you have to pass back and forth. I also eventually expect to add a lot of automatic post-processing type features (captioning, lighting/sound adjustments, "umm" removal, etc.) for people who don't know how to do that on their own.

Any kind of feedback at all is welcome, positive or negative, on whether there's an idea here that you think I could develop into something people would pay for, or if there's something you'd like to see in an app like this. Thanks in advance!
