I edit videos which are shot at 60p, then slowed down 40% and edited into 24p timelines. Normally you can select all your footage in the project/bin panels and change the speed/duration before editing.
But now there's a weird bug after the latest update where clip speed/duration is greyed out (and keyboard shortcut doesn't work) on most clips in the project/bin panels (it still works as expected when selecting clips in a timeline).
The only clips that seem to work are .MOV files with no audio, or mograph preset clips.
Workaround is to select one of the above clips at the same time as the others (ex. place an audio-less .MOV into the footage bin and select all) and then speed/duration works as expected. Bit annoying but at least it's an easy and quick workaround. Hopefully the bug gets fixed soon.
