Description
FixBlendIVTC is a function to restore blend-deinterlaced telecined footage with double blends and 50:50 blend weights.
Note: Decimate (from Decomb) is the only function guaranteed not to mess up this filter, unless you follow the filter with RequestLinear from TIVTC.
Requirements
Required Plugins
Latest versions of the following filters are recommended unless stated otherwise.
- Average
RemoveGrain - part of the RemoveGrain v1.0b package.- RgTools - recommended drop-in replacement for RemoveGrain!
- MaskTools2
Syntax and Parameters
- FixBlendIVTC (clip input, "post", float "bthresh", "mthresh", bool "sbd", clip "dclip")
- input clip =
- Input clip.
- input clip =
- post int (0-6, default 2)
- Postprocessing strength: Post=0 is the fastest, post=5 is the best for bad quality and the slowest postprocessing mode.
- 0 - No postprocessing
- 1 - 0 + chromablur
- 2 - Diffmasked pp (sharp and good for hq sources) - default
- 3 - 2 + chromablur
- 4 - Blurmasked restoring (more soften than 2, but sometimes less artefacts)
- 5 - Combines post 2 and 4 but without chroma.
- 6 - 5 + extra chroma (slowest).
- Postprocessing strength: Post=0 is the fastest, post=5 is the best for bad quality and the slowest postprocessing mode.
- post int (0-6, default 2)
- If these postprocessing modes aren't strong or individual enough for you you can also use your own favorite filter on the restored frames. Therefore set a string with the filter(s) of your choice. Use pp0 till pp6 for the postprocessing mode and add your filter like this:
post="pp4.blur(1)"- If you want to use a filter with input-strings use three quotation marks like in the second example.
- bthresh float (0.0-2.0, default 0.1)
- The blend-threshold can be used to make the blend-detection less aggressive if there are some wrong detections.
- bthresh float (0.0-2.0, default 0.1)
- mthresh float (0.0-1.0, default 0.1)
- The motion threshold for the function. If the frame-difference is smaller than mthresh the function don't trust the blend-detection and does nothing. This helps decimating and can avoid side-effects. Sbd enables already some kind of mthresholding, but the 12 fps detection works with really low thresholds.
- mthresh float (0.0-1.0, default 0.1)
- sbd bool = false
- Single-Blend-Detection, it's a bool parameter you should set true for 12fps sources (anime/cartoons).
- sbd bool = false
- dclip clip = input
- This clip is used for the blend-detection and won´t be returned, so that you can preprocess for blend-detection without affecting the output. A light blurring or temporal stabilizing can be really useful sometimes, especially in a source with many artifacts, but normally this feature shouldn't be used.
- dclip clip = input
- Note: The blend-detection-differencing is also used for post 4 and 5. So a too strong preprocessing could maybe have a bad effect on the postprocessing, but I wasn't able too produce such cases till now. Indeed sometimes this seems to be just better for the postprocessing.
Examples
AviSource("blended.avi")
FixBlendIVTC(post=3)
Decimate(cycle=5,quality=0)
LimitedSharpenFaster()
FixBlendIVTC(post="""pp2.Deen("a2d")""")
TDecimate(rate=23.976,mode=7)
Changelog
Foxyshadis
v.1 - v.3:
Required manual offsets. v.1 had broken reversal.
v.4:
Conditional, effective but very slow.
MOmonster
v.5:
Much faster, better detection & single-blend detection.
v.6:
Changed parameters again, better motion mask/influence.
v.8:
Sped up significantly, also more accurate single-blend.
v.9:
Modified for less artifacts, more post-processing choices, bthresh.
