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

What is the file size of one extracted BMP frame?
+
Depends on resolution and BMP 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 WMV produces ~50 GB total. BMP װײַזט אױף אַ קלײנע קאָפּצעטל, װאָס איז אַזוי פּשוט צו פֿאַרשטיין.

Almost always motion blur baked into the WMV 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.
