Hey pal!
A 10 hour video loop is definitely an interesting proposal, always keen to do one! Albeit I think the longest part of the process would be rendering it :P
Would be intrigued to know more about it, how long is the original source that will be looped?
I can definitely work to what you want and get it done rather quickly. Really intrigued on what the video is as well!
All the best,
Jordan
