How much smaller will my video get?

Typically 50–80% with the Smaller preset, depending on the source. The result screen shows the exact saving against your original.

Can I stop a long compression?

Yes — Cancel stops the encoder immediately and frees the memory; nothing is left half-written.

Is there a watermark?

No. GoChronos never watermarks anything, and there's no size cap or signup.
