The video above is an example of my own channel intro. I have been on youtube for 9 years now and am quite proficient in video editing. I will edit a single video that is up to 30 minutes long (there can be more raw footage, but the finished video will be this length, or 10 videos that are 3 minutes or less (any other combination works, 2 videos that are 15 minutes, 3 that are 10, etc).
I can also do other tasks here, such as subtitling a video, rotating a video, etc. Essentially, anything to do with video editing.
