If you want to ensure that these frames are blended, enable this parameter. In a lot of cases, the first and last frames of a video will have a missing field, which would prevent field

FirstLast: Blend First/Last Frames (true/false, Default "False").

Some capture cardsĬapture the fields in the wrong order and using this setting you can fix the issue. Swapping Fields is the process where every second line is swapped with the line above it.

Swap: Swap Fields (true/false, Default "False").

This setting reverses the matching order and The prominent field reversed which may cause interlaced output even though the Some badly authored DVD content or sources captured using a Capture card may have

Reverse: Reverse Field Matching (true/false, Default "False").

Some of these parameters may not be clear so I will explain them in detail: Telecide (reverse=false, swap=false, firstlast=false, post=true, threshold=15, dthreshold=9, blend=true, chroma=false, y0=0, y1=0) Recommended Setting (these are also the defaults if no value is set):

Telecide (Reverse Field Matching, Swap Fields, Blend First/Last Frames, DeInterlace Non-Matching Frames, Field Detection Threshold, Field DeInterlace Threshold, Blend instead of Interpolate, Use Chroma Search, Exclude Line Start, Exclude Line End) Telecide accepts the following parameters: These frames to restore the original 23.976 frame rate.

Decimate, which matches duplicate frames after the Telecide process and removes one of.

Telecide, which matches fields in order to reconstruct the original progressive image and filters out fields.

The Decomb plugin is built from two sections:

The latest version of Decomb can be found At this time, the latest version of Decomb is v3.6 and as such some of the parameters may change inĪ future version. His filter is called "Decomb".īoth these filters work well, but Decomb is currently more evolved and as such will be the plugin I will discuss in So that it too was quite a bit faster than the older VirtualDub version.

Modified the code to allow for dropping of duplicated frames (part of the IVTC process) and further optimized it The Author of Telecide (A field matching filter for VirtualDub) converted his filter to the AVISynth platform and The benefits of this filter is that it was CPU Optimized and was Then Tom Barry, one of the authors involved in the dScaler project took it upon himself to convert his dScaler field matching plugin They had issues with certain hardware and often broke down, not to mention the IVTC processing speed Up until late 2001, the only way to properly IVTC video was using TMPEG Encoder or AVIFile.

IVTC (Inverse Telecine) and Field Matching:Īs many of you that have experimented in IVTC in the past know, IVTCing a video is often a slow and problematic issue.Įspecially when your source is erratic and possibly even noisy (such as Anime or TV Capture). You can obtain the MJPEGCorrect plugin either Here's a simple script that fixes this issue:

When decoding to YUV, decoding to RGB in programs such as VirtualDub doesn't require this fix). I have not verified if this problem exists withĪll MJPEG Video Codecs, but the two most popular codecs (PicVideo & Morgan) both suffer from this issue (only Written specifically to fix this issue with MJPEG videos. Luma (brightness) in MJPEG decoders is often decoded incorrectly to the YUV luma-range, a special plugin was

Now that we dealt with the simpler aspects of just loading our video, we will now see how to IVTC and further
