I'm using RedCine-X Pro Build 10 Beta 10.18644, with Epic 5k full frame footage. There is a bug when locking the aspect ratio.
- Select a clip
- Framing tab
- Lock aspect ratio 16:9
- Center crop; You get a 16:9 section in the middle. If you drag the bottom or top red lines, it will stay 16:9.
- If you drag the right or left red bars to expand, it will extend beyond 16:9.
Once it is over extended, if you drag the top/bottom bars to a new size, the left/right sides will continually flop back and forth between the locked 16:9 size and the over extended size.
Also the cursor will no longer grab the left/right bars where they appear, it will however grab them closer to the center where they do not appear, but their 16:9 lock would have them.
Naturally this is quite annoying and makes framing a 16:9 cut from full frame more challenging than necessary.
A similar problem exists for all the lock aspect ratio options. They can all be over extended, breaking the aspect ratio.
