Is the video uploaded?

No. Frames are decoded into a browser video element and drawn to a canvas; the file stays local the whole time.

Why does scrubbing stutter?

Every jump decodes a frame, which is heavier on long clips and 4K footage. The picture catches up once you release the slider.

Will a long headline get cut off?

No — text wraps to the canvas width with no line limit. That said, anything past two or three lines is unreadable at thumbnail size, so aim for a short headline.
