==Examples==
MPEG2Source() should be used only with MPEG-1 and MPEG-2 video sources. 
 
*To do plain YV12 decoding:
:<pre>MPEG2Source("project.d2v", cpu=0)</pre>
:Note: PATH can be ignored if "project.d2v" is in the same directory as your AviSynth (*.avs) script.
 
*To do deblocking only:
:<pre>MPEG2Source("project.d2v", cpu=4, iPP=true, moderate_v=20)</pre>
 
*To do deblocking on an interlaced source with increased vertical sensitivity:
:<pre>MPEG2Source("project.d2v", cpu=4, iPP=true, moderate_v=20)</pre>
 
*To do deringing only:
:<pre>MPEG2Source("project.d2v", cpu2="ooooxx")</pre>
 
*To select the optimized 32-bit SSE2 iDCT and also output I420 colorspace:
:<pre>MPEG2Source("project.d2v", idct=5, i420=true)</pre>
 
*To convert to YUY2 based on the PROGRESSIVE_FRAME flag:
:<pre>MPEG2Source("project.d2v", upConv=1)</pre>
 
*To do display onscreen information about the video:
:<pre>MPEG2Source("project.d2v", info=1)</pre>
 

==iDCT Algorithm Notes==
The FlasKMPEG readme file contains an excellent technical description of iDCTs. It states:
 
:''"The video information inside MPEG files is stored in the frequency domain rather than in the spatial domain (the images we see). That way, the information gets compacted and that compaction can be used to compress (reduce) the amount of information you have to send over the transmission channel. MPEG uses the DCT (Discrete Cosine Transform) to translate spatial information into frequency information. To bring back the spatial information from the MPEG stream you have to apply the iDCT, that is, the Inverse Discrete Cosine Transform, that undoes the DCT that was used during encoding."''

:''"Although MPEG is almost deterministic (given a MPEG stream the output should be identical in all decoders), the standard has a degree of freedom when choosing the iDCT to use. That way, the decoder can be more easily implemented depending on the hardware below it. What the standard requires from the decoder is that the iDCT meets IEEE-1180 specs, or in plain words, that the error from the iDCT doesn't go beyond that the ones pointed out in the IEEE-1180."''

Which iDCT you should use depends primarily on what CPU you have and to a lesser degree, on how accurate an iDCT you desire. Most people will not be able to tell the difference in quality between these algorithms but they can be easily observed by combining the AviSynth filters [[Subtract]]() and [[Levels]](). All of the available options are IEEE-1180 compliant, except for '''[[SSE]]/[[MMX]] (Skal)'''.

*Qualitywise: '''IEEE-1180 Reference''' > '''64-bit Floating Point''' > '''Simple MMX (XviD)''' > Remaining iDCTs.
*Speedwise: '''SSE2/MMX''' and '''SSE/MMX (Skal)''' are usually the fastest. The '''IEEE-1180 Reference''' is easily the slowest.

TIVTC

2014-09-20T03:36:20Z

Meru: Corrected link

{{Filter|[http://bengal.missouri.edu/~kes25c/ tritical]|1.0.5|[http://bengal.missouri.edu/~kes25c/TIVTCv105.zip TIVTCv105.zip]|IVTC & Decimation| |}}
{{FilterCat|Plugins|External_filters|IVTC|Decimation}}
==Description==
'''TIVTC''' is a plugin package containing 7 different filters and 3 conditional functions. The seven filters included are '''[[TIVTC/TFM|TFM]], [[TIVTC/TDecimate|TDecimate]], [[TIVTC/MergeHints|MergeHints]], [[TIVTC/FrameDiff|FrameDiff]], [[TIVTC/FieldDiff|FieldDiff]], [[TIVTC/ShowCombedTIVTC|ShowCombedTIVTC]],''' and '''[[TIVTC/RequestLinear|RequestLinear]]'''.
*'''TFM''' is a field matching filter that will recreate the original progressive frames in a telecined source, and '''TDecimate''' is a decimation filter that removes duplicates. These filters can be used together to achieve an [http://en.wikipedia.org/wiki/Ivtc ivtc] or separately to accomplish other tasks.
*'''TDecimate''' also provides special options for handling hybrid material which include vfr via matroska (using a timecodes file) and blend decimation/upconversion for cfr solutions.
*'''Mergehints, RequestLinear, FrameDiff, FieldDiff,''' and '''ShowCombedTIVTC''' are special utility filters included to help perform specific functions. The conditional functions are '''IsCombedTIVTC, CFieldDiff,''' and '''CFrameDiff''' which can be used via Avisynth's conditional filtering environment to test if frames are combed, determine how well two fields fit together, or calculate the difference between frames.

==Usage Examples==

'''NTSC cases''':

1.) NTSC Film, normal source (not anime or cartoon). One pass.
mpeg2source("c:\oursource.d2v")
tfm(d2v="c:\oursource.d2v")
tdecimate()

2.) NTSC Film, anime or cartoon source. One pass.
mpeg2source("c:\oursource.d2v")
tfm(d2v="c:\oursource.d2v")
tdecimate(mode=1)

3.) NTSC Hybrid, using blend decimation on video sections (not anime or cartoon). One pass.
mpeg2source("c:\oursource.d2v")
tfm(d2v="c:\oursource.d2v")
tdecimate(hybrid=1)

4.) NTSC Hybrid, using blend decimation on video sections, anime or cartoon source. One pass.
mpeg2source("c:\oursource.d2v")
tfm(d2v="c:\oursource.d2v")
tdecimate(mode=1,hybrid=1)

5.) NTSC Hybrid, using vfr via mkv (not anime or cartoon). One pass.
mpeg2source("c:\oursource.d2v")
tfm(d2v="c:\oursource.d2v")
tdecimate(mode=3,hybrid=2,vfrDec=0,mkvOut="mkv-timecodesfile.txt")

6.) NTSC Hybrid, using vfr via mkv, anime or cartoon source. One pass.
mpeg2source("c:\oursource.d2v")
tfm(d2v="c:\oursource.d2v")
tdecimate(mode=3,hybrid=2,vfrDec=1,mkvOut="mkv-timecodesfile.txt")

7.) NTSC, two pass (enables use of conCycleTP parameter) mkv vfr for hybrid source.
First pass:
mpeg2source("c:\oursource.d2v")
tfm(d2v="c:\oursource.d2v",output="matches.txt")
tdecimate(mode=4,output="metrics.txt")
Second pass (not anime or cartoon):
mpeg2source("c:\oursource.d2v")
tfm(d2v="c:\oursource.d2v",input="matches.txt")
tdecimate(mode=5,hybrid=2,vfrDec=0,input="metrics.txt",tfmIn="matches.txt",mkvOut="mkv-timecodesfile.txt")
Second pass (anime or cartoon):
mpeg2source("c:\oursource.d2v")
tfm(d2v="c:\oursource.d2v",input="matches.txt")
tdecimate(mode=5,hybrid=2,vfrDec=1,input="metrics.txt",tfmIn="matches.txt",mkvOut="mkv-timecodesfile.txt")

'''PAL Cases''':

1.) PAL, no decimation (just field matching)
mpeg2source("c:\oursource.d2v")
tfm(d2v="c:\oursource.d2v")

2.) PAL, decimate 1 in 25 (most similar)
mpeg2source("c:\oursource.d2v")
tfm(d2v="c:\oursource.d2v")
tdecimate(cycle=25)
