Can no longer turn the video compression off with new Storyline 3 update...

I am also hitting the 'replace video' bug where it doesn't allow you to change the video compression... super frustrating. Yes, my videos are all exported with the 'Main' profile.

Fastest workaround I've come up with so far:

1. Import the video from file as a NEW video into the slide.
2. Delete the new video you just inserted.
3. Now use the 'Replace video' functionality and this time it will allow you to change the compression setting to 'None'.

This means you can maintain all the triggers, animations, timings, etc. without having to recreate them all over again.

My guess is that it's only reading the file settings correctly when you import the file using the new video option, but then caches them so they're available for the replace video function to work correctly afterwards.
