thanks man! I just use iMovie on my Mac. Recorded 4k 24fps. But when I exported it to my computer I only saved in 1080p. Could have been the problem. But compressing 4k videos takes FOREVER.Nice work! Seth's Bike Hacks recommends that new content creators should stick to about 5 minutes until they build up a large audience. I've found that my 5 minute video nets me close to 3 minutes of watch time per video.
I also think you need to step up the bit rate in your video. It will get rid of all those small pixels you see throughout the video. Do you use any specific editing software? If so, it might have an option to set your bit rate. You want to match the bit rate to the original file so the video comes out clean on YouTube.
Other than that, it was a pretty good edit!
