FCP has had a severely crapping logging system since day one. Especially for doing what you are doing. But I found a good workaround that only means touching the mouse once each clip, and never moving it. Except when changing reels. I assume you’re entering all the clips for one particular reel, then moving to another? If not, maybe you can adapt this.
1. Enter the reel
2. mouse click on the TC in field (leave the mouse pointed there)
3. enter the in
4. tab once to the TC out field and enter the out TC
5. press F2 (log) and it will ask you for the description, type it in
— side note, if you have a repetitive description, you can copy it, and then paste it after each F2, then adjust —-
6. click the mouse and you’re back at the TC in.
So except for the 1 mouse click, it operates like Avid or Media 100 logging, instead of the idiotic tabbing through fields like duration, take, scene, etc
