mocha has the ability to interpolate interlaced footage. This must be set up when you start your new project: separate fields. Please note: For rendering modules such as Remove, Insert and Stabilize, interlaced footage can be difficult to work with. Imagineerrecommends working inside mocha on frame based clips. Consider processing interlaced footage into frame based , de-interlaced footage in another program. You may then remove and render out of mocha at full size, making the remove tool work easily in your shot. You can then reprocess the clip to be interlaced once again.
