At what resolution does each extracted JPG frame come out?
+
The same resolution as the MKV video — a 1080p MKV produces 1920×1080 JPG frames; a 4K MKV produces 3840×2160 JPG frames. Use the resize utility after extraction if you want smaller thumbnails or social-media-sized crops.
Will the extracted JPG images preserve the MKV color grading?

What is the file size of one extracted JPG frame?
+
Depends on resolution and JPG codec. A 1080p PNG frame is typically 2 to 5 MB; a 1080p JPG at quality-85 is 200 to 500 KB; a 4K PNG is 6 to 15 MB. At the extreme, every-frame PNG extraction of a 10-minute 1080p MKV produces ~50 GB total.

Almost always motion blur baked into the MKV source — the camera or subject was moving when the frame was captured. Pick timestamps from static scenes, or extract adjacent frames and choose the sharpest. The pipeline does not synthesize detail that was not there.
