Hi, all --
Congratulations on the release of 1.4; it looks like there are going to be some great new features to play with.
Alas, though, there are issues I'm experiencing on 1.4 in a project I was working on before updating:
1. Keyframes seem to be moved on some elements. I had a title superimposed over another piece of video with a "big hole" distortion to warp the title in, and a dissolve applied to the end of the clip. The keyframes for the placement of the title element may not have moved, but after moving the clip from point 1 to point 2, the title element suddenly moved back toward center, as if there were a new keyframe added, but there wasn't a new keyframe visible in the motion editing interface. I wound up just deleting the keyframes and resetting them, but now think this may be a bigger problem on other projects that have lots of keyframe movements.
2. Stuttering playback. I'm using a first-generation iPad Pro 12.9", so it has a lot of horsepower, but now if there are a couple layers of video, I get stuttering in the playback. Before the update, the exact same timeline was playing just fine. So something has happened.
Hope these reports are useful, and I hope you're able to issue an update that corrects at least the playback issue soon.
