Thanks for the info, Vince.
I did notice, in many other forums, the GoPro being a common denominator when it came to painfully slow rendering.
I put all my projects in Media Encoder to export for YouTube at 1080p. In hind site, I think that’ll thin things out, but it may be a bit to extreme. This was before I saw your reply. I’ll try the ProRes.
Thanks again,
Alex
