Collection of functions for working with interlaced content in VapourSynth.

Overview

vsfieldkit

Collection of functions for working with interlaced content in VapourSynth. It does not have any hard dependencies outside of VapourSynth.

Included functions:
vsfieldkit.assume_bff(clip)
vsfieldkit.assume_progressive(clip)
vsfieldkit.assume_tff(clip)
vsfieldkit.double(clip)
vsfieldkit.group_by_combed(clip)
vsfieldkit.group_by_field_order(clip)
vsfieldkit.scan_interlaced(clip)

See the documentation for more information.

    Allow EdgeFixer plugin instead of ContinuityFixer

    Currently there's no release of ContinuityFixer plugin that works with vsfieldkit. Also, according to the author, EdgeFixer should be used instead: https://github.com/MonoS/VS-ContinuityFixer/issues/2

  • fill_analog_frame_ends updates

    fill_analog_frame_ends updates

    • Allow overriding the pre-fill mode and gives better error messaging when the fillborders plugin is missing the requested mode. The default mode is now "fillmargins" instead of "fixborders" in order to work with the release version of fillborders.
    • Work with progressive clips cropped by factors smaller than interlaced subsampling.
    • More compatible with code autocompletion via removal of decorators.

    Fixes JustinTArthur/vsfieldkit#4.

  • Allow brightening of newly scanned lines in scan_interlaced

    Allow brightening of newly scanned lines in scan_interlaced

    Just as we support decaying old lines to a decay base with decay_factor, we could also allow brightening new lines. Borrowing from audio engineering, calling itattack_factor would compliment the existing decay_factor.

    Based on a suggestion by @Tefad.

  • fill_analog_frame_ends: mod2 field height required on pre-cropped progressive material.

    fill_analog_frame_ends: mod2 field height required on pre-cropped progressive material.

    In case fill_analog_frame_ends encounters interlaced frames, it always attempts field separation. This breaks when the function is fed a progressive clip that's been cropped to something other than mod2 half-height. Ideally, fill_analog_frame_ends is applied before crops, but we can't guarantee users won't try.

  • Add channel separation repair filter using the BBC PAL Transform

    Add channel separation repair filter using the BBC PAL Transform

    For video that's been transmitted as a PAL composite signal (PAL CVBS or PAL terrestrial broadcast), the compositing of Yʹ, U, and V signals causes crosstalk, projected as rainbowing and dot crawl artifacts in the decoded pictures.

    The BBC Transform PAL Decoder originally conceived by @jim-easterbrook has been celebrated in its ability to better reconstruct the original separate Yʹ, U, and V signals from the composite signal prior to decoding to light/color samples. There's even evidence it can help with NTSC composite video artifacts after reinterpreting the NTSC video as PAL. I'd love to see this concept realized as a VapourSynth filter so it can be used alongside fill_analog_frame_ends and upstream of TFM/VFM or QTGMC.

    To perform this repair in transform space within a VapourSynth filter, we'd want to first construct a pseudo-analog PAL CVBS signal using something like pulse code modulation of 4-times-subcarrier-frequency, run the PAL Transform algorithm on the PCM data, then re-digitize the signal as light/color samples before finally resampling the original clip's format characteristics.

    The open source ld-decode project has implementations of conversions between motion RGB and PAL CVBS PCM data. The open source pyctools-pal project has a Python and Cython implementation of the BBC PAL Transform for PAL CVBS PCM. However, both @atsampson's PAL CVBS conversion code and @jim-easterbrook's PAL transform code in these projects are only licensed to the public under the restrictive GNU Public License. A note for myself and anyone looking to add this to vsfieldkit: please avoid looking at the ld-decode/tools/ld-chroma-decoder or pyctools-pal/src/pyctools/components/pal source directories when working on this task. vsfieldkit is currently licensed to the public under the less restrictive MIT License.

    My first try at this in vsfieldkit would be to open a subprocess to installed ld-chroma-encoder and ld-chroma-decoder executables if the user has installed them. The function would convert to/from the ld-* toolchain native RGB format using typical zimg/core.resize resampling kernels. This could potentially avoid licensing issues, but is likely to be inefficient.

    A C, Rust, or even Python implementation of the CVBS conversion and PAL transform separation for VapourSynth could potentially be done in a separate GPL-licensed project using code or deriving code from ld-decode and/or pyctools-pal.
