Information in case someone ever needs it or wants to contribute to this thread…
In my case:
The time line is 102 minutes, 1920×1080 23.976 YUV 10bit 4:2:2 with 48KHz 24bit stereo audio. I added a 5 second motion logo at the front (which was 1920×1080 23.976 YUV 10bit 4:2:2 with 48KHz 24bit stereo audio). I laid in 2 minutes of corrected end credits (a single clip dropped onto the main time line to replace the corresponding footage). That clip was also 1920×1080 23.976 YUV 10bit 4:2:2 with 48KHz 24bit stereo audio.
I’m am currently exporting to 1920×1080 23.976 YUV 10bit 4:2:2 with 48KHz 24bit stereo audio and it looks like the render will take more than 3 hours. I am definitely going to miss my deadline. Blurg.
