Hey folks,
USING VEGAS 15.0 BUILD 416
I have searched the forum and have not found a specific answer to my problem.
Project Settings: (should 8 Bit and 32 Bit make a difference?)

I am importing GH5 10 Bit Video Files :

Please see video to see what the issue looks like.

All video files play no problem on my computer.
As a workaround I can convert these files using Handbrake but one of the big reasons we upgraded to Vegas 15 was to be able to edit these files natively.
Can anyone suggest what I am doing wrong?
Many thanks,
Steve
