Frame control

Interlaced source.

Check this option to make SpotRemover treat the video stream as interlaced.
This enables detection of spots on each field independently.

Detect duplicate frames.

When this option is checked, SpotRemover will attempt to detect duplicate (repetitive) frames.
If a duplicate frame is detected it does not go into the processing.
At the output, the corresponding frame is made as an exact copy of the preceding processed frame, thus keeping the frame rate unchanged.
This effectively enables spot detection in repetitive frames, and can be used for processing the video sequences originated from video sources with lower frame rate.
One examlple is  8 mm film projected at 18-20fps and captured with PAL/NTSC camcorder.

Do not use this option if your video was telecined. (Read here for more details.)

Turn this option on only if you really need to, as this slows down the processing.
