Data Grid Filtering | United Bluerise
The idet filter will add analysis metadata to each frame, which will then bediscarded. At the end, the filter will also print a final report with statistics. Cumulative number of frames with the bottom field repeated from the previous frame’s bottom field. Cumulative number of frames with the top field repeated from the previous frame’s top field. Cumulative number of frames that could not be classified using multiple-frame detection. Cumulative number of frames that could not be classified using single-frame detection.
- Unused delays will be silently ignored.
- Specify the band-width of a filter in width_type units.
- The count of the input frame for video or the number of consumed samples,not including the current frame for audio, starting from 0.
- Pass difference between input, 1st input and error signal estimate.
- Higher values increases reduction of cross-luminance.
The printed times and duration are expressed in seconds. Thelavfi.freezedetect.freeze_duration andlavfi.freezedetect.freeze_end metadata keys are set on the first frameafter the freeze. Assume the first PTS should be the given value, in seconds.
Structure of the model
Simple spline consisting of two polynomials, joined by a single pivot point. The parameter gives the pivot point (in PQ space), defaulting to 0.30. EETF from the ITU-R Report BT.2390, a hermite spline roll-off with linearsegment. The knee point offset is configurable. Note that this parameterdefaults to 1.0, rather than the value of 0.5 from the ITU-Rspec.

This includes the preceding frames as well as thesubsequent frames. However, for the "boundary" frames, located at the verybeginning and at the very end of the audio file, not all neighbouringframes are available. In particular, for the first few frames in the audiofile, the preceding frames are not known. And, similarly, for the last fewframes in the audio file, the subsequent frames are not known. Thus, thequestion arises which gain factors should be assumed for the missing framesin the "boundary" region.
Video Sinks
The video stream will be the first output stream ifactivated. Set output size for each input stream when grid is set. If this optionis not set, this filter will set output size by default to the size of thefirst input stream. For the syntax of this option, check the(ffmpeg-utils)"Video size" section in the ffmpeg-utils manual.
