Settings......what ever settings optimal and nominal for 4K video rendering for weddings and sweet 15's and girls with guns music videos. Nothing major. However some are large files, like 30 minutes each of 4K. For instance when they cut the cake, when they throw the bouquet in the air, etc....small segments small bursts of videos but none of them are more then 30 minutes long. But there are numerous videos of course each at 30minutes max.
