I don't like people who buy one kilogram Gold and want to make a proud Crown from it with neither sufficient knowledge nor tenacious study.
HW: my signature, Soft: VEGAS pro 20
1, I established an 8K/QFUHD project with 29.97fps due to the main source material.
1a, I use SWAPfile instead of that ragged proxy which can only be viewed in again that nasty Preview/Draft quality.
2, after editing I swapped back the origins and began to render.
2b, there's no 8k-template with 29.97fps, so I changed the framerate.
3, I got several times freezing and didn't know why.
3c, every time the freeze happened at this junction, I tried trimming, moving, upside down repositioning...all failed.
4, thinking, putting myself in VEGAS shoes...why no template for 30p?
4d, or I change my frame rate to fit the render default. I did.
