Moet locked zijn.

There are 3 basic operating modes for frame rate (or vertical frequency) conversion:

Source-lock mode where the output frame rate exactly matches the input frame rate.

Arbitrary output frame rate which is not locked to the input.

Progressive source-lock mode with frame rate conversion to an even multiple of the source frame rate. 24 Hz film-source material using a 3:2 pulldown pattern can be output with 2:2 pulldown at 48 Hz or 3:3 pulldown at 72 Hz. 25 Hz film-source material using a 2:2 pattern can be output using 3:3 pulldown at 75 Hz. These output rates are fully locked to the original 24 or 25 Hz source rate and are not actually 'floating' as with a several other scaler products which offer 72 or 48 Hz output frame rates without really locking to the original film source rate.
