| + | parity | ||
| + | The picture field parity assumed for the input interlaced video. It accepts one of the following values: | ||
| + | |||
| + | 0, tff | ||
| + | Assume the top field is first. | ||
| + | |||
| + | 1, bff | ||
| + | Assume the bottom field is first. | ||
| + | |||
| + | -1, auto | ||
| + | Enable automatic detection of field parity. | ||
| + | |||
| + | The default value is auto. If the interlacing is unknown or the decoder does not export this information, top field first will be assumed. | ||
| + | |||
| + | deint | ||
| + | Specify which frames to deinterlace. Accept one of the following values: | ||
| + | |||
| + | 0, all | ||
| + | Deinterlace all frames. | ||
| + | |||
| + | 1, interlaced | ||
| + | Only deinterlace frames marked as interlaced. | ||
| + | |||
| + | The default value is all. | ||

| + | Using BeyBlade as a source. | ||
| + | |||
| + | Default for ''mode'' is ''send_frame'', which will output one frame for each frame; the output frame rate is constant at 30000/1001 (29.97, NTSC). | ||
| + | |||
| + | If I set it to create a frame for each field (''mode=send_field''), it will come out at 60000/1001 constant instead (59.94). | ||
