Hi guys.
I’m not sure if it’s a bug or I’m just doing something wrong but this is what happened to me.
I’m setting everything up in sequencer - camera, focal length, aperture and position. I’m adding key frames for all of them and because I’m still learning this tool I’m not doing anything fancy. I’m changing only focus distance. Transformation keys are set properly - first frame has the same values like 50th frame where the next key is. Problem is that camera should stay in the same position for that time but moves slightly down and go back to proper position. So I do additional tests adding keys on 25th frame and now between 1st and 25th frame everything is fine, no movement but unfortunately it moves on 26-50 . So I test it several times and suddenly discover that sequence where everything was fine now is messed up again. (After few minutes writing this I went back to play it again and… it works ok).
So I moved camera, just a little bit up. I changed also focus distance. During movement FS doesn’t change from 50 to 100 but going down to 15 and then up to proper value. In the moment when it’s going up there are no keys.
