Worked example: a course still that should not be 1920 wide
If the lesson player is 800 CSS pixels wide, a 1600 × 900 source is enough for 2× screens. Crop to 16:9, export here, then compress only if the LMS also states a KB limit.
What this job is for
Blog Open Graph images are often 1200 × 630 (closer to 1.91:1). Use the Facebook post size page for that shape. Use 1600 × 900 when you specifically want 16:9 at this pixel count.
Useful limits
Enlarging a 640 × 360 clip to 1600 × 900 will look soft. Start from a larger 16:9 master.

Frequently asked questions
How does 1600 × 900 differ from 1920 × 1080?
Same 16:9 ratio; fewer pixels. Use 1600 × 900 when the extra 1080p pixels will be thrown away.
Is this an official slide size?
No. It is a practical 16:9 canvas. Widescreen slide files are often 1920 × 1080 or 13.333 × 7.5 inches at 96–150 dpi.
Does Image Cosmos upload the still?
No.
