Optimally Shrinking Video File Sizes

Question

My videos in Premiere Pro are 4k versions for YouTube, and Square sequences (2160x21260) for social media. My social media scheduling platform (Zoho) limits videos to LinkedIn to 200 MB.

Example --- an 8-minute video:
Adaptive High Bitrate = 2.6 GB

Adaptive Low Bitrate = 802 MB

The goal is best quality that will stay square and not have black framing around it. How do I get there?

Neither Premiere nor Resolve are designed to milk long-GOP encoding options for quality at lower bitrates. At least not nearly as easily as say ffmpeg or ShutterEncoder can, both freebies.

ffmpeg is all command-line options, not something many users find easy to master.

ShutterEncoder uses the same tools, just wrapped in an easier to learn UI.

Both give you access to tools to refine your settings with a lot of granularity. It can take some testing, but I've seen people accomplish a lot with them.

What you would do is say export a ProRes 422 or Lt from Premiere as your Master. Take that file into Se or ffmpeg and setup your H.264/5 deliverables export.
