Is My Camera Not enough for VIDEOHIVE?

Hello Fellow Friends

I am Struggling to get my footage accepted as they reject all of my footages due to quality issues

I think my camera is not quite enough to even come closer to VIDEOHIVE now.

It’s a Canon EOS M6 Mark II ( Mirrorless) Camera
Lenses Canon EF-M 15-45mm kit
Canon Ef 50mm F1.8 STM

If anyone know about the minimum gear you need please let me know. So I can at least make up my mind .

Thanks in Advance
