2:2 Pulldown detection uses the comb factor measurement to determine whether the material was sourced from film or from video. The default settings have been found to work with a wide range of inputs but there are problems with some highly detailed images.
| Setting | Default | Description |
|---|---|---|
| Pulldown Threshold Low | 40 | This is the percentage drop in comb factor that will be considered to be a candidate film mode. |
| Pulldown Threshold High | 10 | This is the percentage increase in comb-factor that will be considered evedence that we are no longer in film mode |
| PAL Video Mode | Greedy 2 Frame | This is the mode that will be used when film mode has not been detected |
| PAL Pulldown Repeat Count In | 3 | Number of times film mode must be spotted in a row before a switch to film mode |
| PAL Pulldown Repeat Count Out | 1 | Each time bad pulldown is encountered the count is decremented starting at "PAL Pulldown Repeat Count In", once the count reaches this value then we go back to video mode. |
| Max Calls to PAL Comb Method | 20 | If we have tuned off "Bad Pulldown Filter" then this is the number of calls allowed to the bad cadence method before switching back to video mode. |
| PAL Bad Cadence Mode | Greedy | If we have tuned off "Bad Pulldown Filter" then this mode is activated when bad cadence is detected. |
