Rekordbox requires a lot of processing.
Compared to other software that has video function (Serato, DJ Pro, Virtual DJ, Cross DJ, ...) Rekordbox is extremely heavy, videos can not be played even in low resolution.
I am using a MacBook Pro with I5 processor, 16 gigabytes of memory and Intel HD Graphics 3000 graphics card with RB 5.2 and is impossible to play videos. In other programs videos works perfectly.
The engineering of the program needs to be revised so that it does not need to spend an extreme financial value on a computer just to run the RekordBox. Otherwise use other platforms will be the most ideal.
