Hi, I have recorded a video mix using the Serato SL3. I export it and it rendered for 30 min, (60 min mix). when i try to open it quick time i get an error message saying that it's not able to open? Any idea what i could be doing wrong? Also, noticed when using ME, there is sort of a watermark in background of the video. It sort of looks and acts like a quartz BUT i have the quartz option off. It also does not appear in the original video when i play it on my iMAC. Any ideas there. Thanks for the help..
