Closed GOP and Keyframes for Editable Masters
Specify closed GOP, a one-second I-frame interval, and a transcode-on-ingest so a human editor can recut generated MP4s without a render farm.

Resample every 44.1 kHz generate on ingest, use a real anti-alias filter, and keep the project at 48 kHz / 24-bit so export does not click.
Catch inter-sample peaks with a true-peak limiter at −1.0 dBTP before AAC, because a brickwall at 0 dBFS still fails QC after the encode.
Reels take MOV or MP4, H.264 or HEVC, 23 to 60fps. Stay under three minutes if you want recommendations, including from a 25fps timeline.
Organic LinkedIn video is 15 minutes, 1:2.4–2.4:1, 256x144–4096x2304. Ads and Pages publish different sheets. One conservative export clears all three.
Most social delivery wastes the 4K premium. The three cases that earn it, the reframe arithmetic behind them, and a per-destination resolution rule.
Shorts cap at three minutes and 1080p. A hard delivery ceiling changes what generation resolution is for, and turns downscaling into a quality decision.
