Mara Kazantzaki makes sense.  I think the way to avoid this is to shoot wider with both horizontal and vertical in mind.  If you film in 4k then you're able to crop and it looks fine.  I'll do some more content in the shorts course about ways to shoot and edit vertical from horizontal footage. 

The question for you is who is the audience for your content.  Would they be interested in both topics on one channel?  If not then pick one of the two.  With a channel you really want to focus on one audience and make all the content for them. 

A great place to start for more info on coming up with your channel direction is my YouTube Core Training Course: https://www.creatorfilmschool.com/programs/learn-youtube?category_id=124966

Personally I would avoid NAS systems unless you absolutely need access to it via the web.  I used Synology for a while and it was frustrating for me to deal with.  

Now I use a Raid that I built with an OWC enclosure.  Here's a video where I break down my whole workflow from camera to to final archiving of data.  

Lassi Kaleva You can crop into 1920x1080.  You will be loosing resolution but also shorts are mostly being viewed on a phone so probably wont matter that much.  

However, I still suggest shooting in 4k to always have plenty of space to be able to crop in.  Much better option than trying to use a 2nd camera.  That just seems like a pain to manage and then things like eye line will be off if you're talking to the camera.  

I plan to add some additional lessons in my shorts course about my process for shooting and editing shorts.  It will give you more insight into how I do it.  

Awesome!  What kind of travel do you do and what kind of videos do you plan to make on your channel? 

Peter Fritz No prob!  If you don't have a way to auto generate captions in Premiere Pro then you can output your video and bring it into CapCut.  There is an auto caption feature that works super well in that software 

I edit in Final Cut Pro and I use an app called captionator that auto generates the text on screen for me.

Make sure everything is updated and try working in a new FCP file. If that doesn't work then sounds like a processing issue.  What are the specs of your computer?  What kind of footage are you dealing with.  You might need to proxy or optimize the footage so that it will be able to edit on your timeline with your computers specs.  

Awesome!  Excited to see what you do with your channel!  Analysis Paralysis happens to all of us at some point.  I've found the best way to escape it is to start making videos.  When my head is down and I'm moving forward that feeling starts to go away.  One way to do this is start making some short form content.  Takes less time and you get that feeling of accomplishment by finishing a video faster which will help encourage you to keep going.
