Yet more Premiere 2017 bugs.
So, I've been using Premiere 2017 for the last 6 weeks pretty much every day editing three short films and I love how powerful it is.
Unfortunately I keep finding more and more weird bugs. We'll have to see in the long run if I can live with them or I move back to Final Cut (which is idiosyncratic but not full of this many bugs - it feels like the code needs a re-write or it needs porting to the Mac better).
The latest I can't work around:
1. Earlier I exported a small piece of AIFF audio.
2. Now I go to Export > Media and one of my files (not the one I exported audio only from earlier) is locked into only exporting audio. The 'Export video' checkbox is greyed out.
I've searched the web, these forums and I've re-launched the program but to no avail. I could export video yesterday and switch between audio and video these past few weeks but today...
Can someone enlighten me as to why I can't currently export video from a pro video-editing application?
Thanks a lot.
