What are your render settings in AME?
What happens if you render directly from After Effects into an intermediate format first?
I've tried rendering as ProRes 4444 and also to AiM (the codec used by the media server these files will play from), both with QT wrappers. My renders have all come directly from After Effects.
Are you suggesting I use Media Encoder? I'm not actually sure how to do that!
Thanks for the reply!
For some reason, I was thinking you were rendering from AME already.
You could try taking one of your ProRes files that you rendered from AE into Adobe Media Encoder to make your AiM file. See what that does.
You could also try sending your AE comp directly to the Adobe Media Encoder to have it render it directly there.
I wonder if that extra black frame is due to some sort of odd frame rate mismatch. What frame rate is your AE comp? What frame rate is set in your render settings?
What happens if you trim the last, black frame off of the end in Premiere Pro and render your AiM file from Premiere?
My comp is at 25, as are my renders.
If I trim the last frame off in Premiere I still get an black frame after the media end recognised by Premiere but I also lose my alpha channel!
Stupid question - How do you render from AE in Media Encoder?
Wait, so you import a ProRes file in Premiere Pro, trim off the black frame, render the AiM, and the resulting file has another black frame in it? If so, something screwy is happening with the codec in your encoding somewhere.
There is a menu command in AE to send your comp to the Adobe Media Encoder. See this.
If this doesn't work, for the awards show, can the video playback be paused? If so, you might consider taking your AE render into Premiere and then just make the video a bit longer with a freeze frame of the last frame. Then the guy running the video system can just pause it as his leisure.
I agree, something really screwy!
Unfortunately Media Encoder is also adding a black frame to my renders.
Building long pauses into the comps isn't an option, unfortunately. Thanks for your suggestions though.
The Avolite Media S6 video playback system does accept ProRes 422 and can handle six simultaneous streams of 1080 footage at 25 fps with ProRes 422. Granted, it isn't as good as it would be with the AiM codec (16 simultaneous streams), but might be acceptable for your use if you're not doing that many videos at the same time.
If that isn't acceptable, my last-resort suggestion would be to try rendering with an older version of AE. I'd try CC 2014, then CC, then CS6. (They're all included with your Creative Cloud subscription. See here for how to download them.)
If that fails, you might need to contact Avolites support and see if they are aware of a fix.
You can open a project created with the CC 2015.3 or CC 2015 releases in the CC 2014 release. You can save a file back to the original CC release in CC 2014, CC 21015, or CC 2015.3. You can save a file back to CS6 from the original CC release.
You might also consider seeing if there is an update available for that codec.
