I actually swapped to filming full time and prefer the custom video scene better as it can be less of a hustle than caming.
If you don't want to put too much work into it, record your cam shows, maybe with an external camera, then all you have to do is edit out the sellable parts using a software and put the clip for sale. I recommend using Filmora as it's not too tech heavy but flexible to add watermarks and some other cool stuff with text and transitions, etc. If you are good with tech, get Final Cut Pro and if you want to heavily edit your clips video, get Davinci Resolve (free download). For the basics you do jump cuts and then you can add your PNG (transparent) watermark on a PIP layer in the bottom corner, then edit out to .mp4 as either 720p, 1080p, or 4k depending on what camera you filmed the clip with.
Once you get at least 10 clips, I highly recommend selling on multiple platforms. The best higher traffic sites include ManyVids, Clips4Sale, and IWantClips. You can enable your custom clip settings for more earnings too. Fetish clips do tend to sell better for me as well verses vanilla, just pay attention to what clips are selling and what aren't and go from there for what you post!
The greatest thing about filming custom videos is you don't have to guess whether or not getting ready to work for the day will be profitable because the clip orders have already been processed. Also know, the longer you've established yourself for selling custom clips, and clips in general, your sales will likely go up assuming you stay active with uploads, advertising on twitter and other platforms, etc.
P.S. If you want to make a big investment to filming clips, I highly recommend a Canon G7X camera and umbrella lighting for starters, otherwise a webcam and basic 3 point lighting is a temporary fix
