I am music composer and would like to ask you how to create long videos with pictures and audio for youtube. I noticed there are many of those (for 9 hours long) on yuoutube. What are the best settings for export. I also used tunestotube, but they limit file size to 100mb so mp3 quality must be very low if i want to create 5 hours long audio track for youtube. I need them to be at least 720hd. Is there an alternative for tunestotube or maybe it's very easy and fast to create it in adobe premiere or smth?
