in reply to: Export Alpha?
Select “individual clips” from the top of the render settings window. Then when you choose a format that supports an alpha channel the render alpha box will magically appear under the resolution drop down menu.
If there’s nothing happening you don’t need to put a lot of bit rate for the video. The encoder should use only what it needs so if you have stills it should keep the bit rate pretty low.
Well parsing the error message could mean that you have a transition where you don’t have enough tails or heads. You can do a transition without enough heads or tails but you’ll get freeze frame for the duration and I believe Premiere will warn about this. There will be a slash pattern on the transition.
