I been a independent film director and writer for years now and been putting all my short films on my YouTube channel. The challenging part is working the films to change music and such to avoid the copyright guidelines on YouTube. So been using AI music creator to generate new music and so far it's been very helpful.
The other thing I come across is while scanning thru past videos is noticing scenes I wish could change and so I click on the files and start editing it to my satisfaction. To sum it up YouTube is a great platform to show your work but it also helps to challenge your potential on creating a better product each time you upload. So it has been keeping me busy as of late.
