* you have a lot of great advice about audio on the comments here - and they’re right, decent audio is a must. I use a DJI wireless lav for most stuff, but also have a Rode NT-USB for tabletop stuff and their shotgun mic on-camera for sync audio and quick pieces to camera when out and about. I usually record main audio into audacity via a behringer audio interface.
* get a good editing program, and get good (which means efficient) at using it. You’ll spend a lot of time in it. Personally I use the studio version of davinci resolve, other opinions are available.
* it can be feast and famine. I started my channel in Jan this year, and hit 1000 subs / 4000 hours at Easter. Monetised a couple days later. I’ve earned about twenty-five pounds since then - it’s gone quiet, but it’ll pick up again.
* don’t pay too much attention (or really, any) to the VidIQs and Channel Makers of this world - they just want to sell you snake oil (but their videos are often entertaining and you can learn stuff from what they do - just not so much what they say).
* don’t bother with VidIQ or tube buddy or all that other stuff - spend the money on storyblocks, a better camera, lights, audio gear instead.
* decent lights are worth their weight in gold. Aputure are great, but expensive. Smallrig do very similar kit at half the price.
* probably more specific to me, but filming long-take 4K in a hot kitchen with all the equipment going will challenge even the best heat-management system in your camera
Also FWIW I don’t do shorts any more. I experimented with them and the dopamine hit is great, but I’m a long-form guy. Shorts just skewed my analytics and brought in low-quality subscribers…
