Files named "4K" are sometimes upscaled 1080p; downloads shrink without warning. The checker reads the true pixel dimensions from the stream, settling the question authoritatively.
1280×720, 1920×1080, and 3840×2160 pixels respectively for standard widescreen. Vertical video swaps the numbers.
Odd dimensions usually mean cropping or app-specific exports. Fine for playback; for platform uploads, resizing to a standard frame avoids letterboxing surprises.
