I’m compressing a 33-minute (1440×900, 25 fps) video in Premiere Pro, for online delivery. The first 30 seconds is a talking head, and the rest is composed of still images. It’s basically a narrated slide show with an introduction by the presenter, Zoom-style.
I was provided with his original clip, and he asked me to make a couple of cuts. However, I’m having trouble with the compression.
His original 34-minute clip came in around 55MB, H.264. But I can’t approach that file size without losing too much quality, compared to the original.
I’d love to keyframe the compression, which I recall doing back in the day with Premiere 4.1, to set a high rate for the intro, and low for the stills. Not sure if I can still do that.
How could I get a low file size, but high quality for the talking head intro?
(I’ve used 2-pass VBR, target .25 Mbps, max 20Mbps, audio AAC-44-128, Max quality, KF distance 45, but the file is around 96 MB and the result is blockier than the original.)
Edit: it’s been a while since I’ve worked with highly-compressed source, so if I have to accept this degree of generational loss, sure.
