Variable frame rate

[x265]

I have a DVD which i want to encode with a VFR. What should i do with the v2 timecodes generated my ffmpegsource? Do i need to make any change in the aviscript? :confused:

what do you achieve by using vfr?

That timecode file is purely CFR, because that's how things are stored on a DVD. As Atak_Snajpera said you need to know why you want to use VFR and yes, you would need to change your script.

[x265]

for certain reasons a lot of anime is created with some sections having motion in 23.976 frames each second, while other sections have motion in 29.97 frames each second. You can store it all in one framerate of course, but if you do you will either have to duplicate or remove frames, and that will create jerkiness in the motion. Which is undesirable since it looks bad.

See TIVTC or maybe AnimeIVTC for automatic or manual CFR to VFR. Some people use YATTA, but I don't know if there's any easy guide out there.

What changes should i make here?

[sneaker_ger]

See the TIVTC/TDecimate docs.

/edit:
removed 1 pass TIVTC example, because it is useless without the explanations.

[x265]

What's the difference between a one pass and a two pass?

What's the difference between a one pass and a two pass?

I'm no specialist on TIVTC, maybe someone else can chime in.

[x265]

maybe someone else can chime in.

I hope so.

[bxyhxyh]

Maybe "megui_folder\tools\avisynth_plugin\TDecimate - READ ME.txt" can help you.

[x265]

what happens when i set a two pass?

[sneaker_ger]

Oh, that readme is really good. I removed my example because you really need to understand what is explained in that readme before actually using it. One and two pass examples can be found here (http://avisynth.org.ru/docs/english/externalfilters/tivtc.htm).

what happens when i set a two pass?

See the examples. Basically the two pass mode will not create black frames for padding, so it can be directly used for the final encode (without blackness at the end, though you could of course ignore that or cut it afterwards) or if you want to do some seeking, but you have to run the first past .. first. (Like running once with "avs2pipemod -benchmark script.avs" or similar.)

[x265]

Ok i will try and let you know.

if you know exactly where the part of 23.976fps and 29.97fps were at, you can manual split them apart, encoded them separately with their respected frame rate, and then join them back together, i supposed there's a mp4box gui that can generate the timecode automatically during appending clips with different frame rate.

[sneaker_ger]

I don't know if there's a GUI but writing a timecode_v1 file by hand for such a case is trivial.

The video of the OP is interlaced but the signs are not.

Is there any guide for learning YATTA?

Example for encoding on VFR using AnimeIVTC:

Create project d2v using Honor Pulldown Flags

First pass

DGDecode_mpeg2source("C:\Users\Isra\Desktop\vob BLEACH 01\VIDEO_TS\VTS_01_1.d2v",info=3)

ColorMatrix(hints=true, threads=0,interlaced=true)

#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-
#VFR - 1pass
#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-

animeivtc(mode=4, aa=0, omode=2, pass=1)

Load your script in virtualdub, go to File-->Run video analysis pass. You must wait until the end of process.

This process generate txt files, not remove.

Second pass:

DGDecode_mpeg2source("C:\Users\Isra\Desktop\vob BLEACH 01\VIDEO_TS\VTS_01_1.d2v",info=3)

ColorMatrix(hints=true, threads=0,interlaced=true)

#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-
#VFR - 2 pass
#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-#-

AnimeIVTC(mode=4,killcomb=1,aa=0,omode=2,e1=38828,i1=40609,e2=41090,pass=2)

Load this script in vdub and automatically generate timecodes.txt, that you must use on matroska file.

e parameter determines last frame film section.
i parameter determines last frame truly interlaced section.
p parameter determines last frame progressive section.

For example, if you video is composed:

frame 0-2600 --> truly interlaced (i1)
frame 2601-32000 --> film (e1)
frame 32001-35000 (end) --> truly interlaced (i2)

You scripts would be:

AnimeIVTC(mode=4,killcomb=1,aa=0,omode=2,i1=2600,e1=32000,i2=35000,pass=2)

You can determine frames using simple script as:

DGDecode_mpeg2source("C:\Users\Isra\Desktop\vob BLEACH 01\VIDEO_TS\VTS_01_1.d2v",info=3)

ColorMatrix(hints=true, threads=0,interlaced=true)

Read documentation of animeivtc for more details.

I get this error when i called the animeivtc 2.12 function.

[Overdrive80]

You must use 2.00 version, version 2.12 is mod but has importants issues.

Is there a tool which can convert v2 timecodes to v1?

Here you can see other example of vfr but timecodes is created for sections:

LoadPlugin("C:\Program Files (x86)\MeGUI\tools\dgindex\DGDecode.dll")
LoadPlugin("C:\Program Files (x86)\MeGUI\tools\avisynth_plugin\ColorMatrix.dll")

DGDecode_mpeg2source("C:\Users\Isra\Desktop\Bleach\VID 2\VideoFile1.d2v", info=3)

ColorMatrix(hints=true, threads=0,interlaced=true)

part1=trim(0,38811).tfm().tdecimate()
part2_in=trim(38812,40609)
part3=trim(40610,41089).tfm().tdecimate()

part2=part2_in.QTGMC( Preset="Slow", EdiMode="EEDI3", fpsdivisor=2).assumefps(part1.framerate)

part1++part2++part3

#Generate timecodes file for sections

WriteFile(last, "timecodesv1.txt" ,""" "# assume 29.970030" """, append=false)

WriteFile(last, "timecodesv1.txt" ,""" "0," """, "part1.framecount", """ "," """, "part1.framerate")

WriteFile(last, "timecodesv1.txt" , "part1.framecount+1", """ "," """ , "part1.framecount+part2.framecount-1",\
""" "," """, "part2_in.framerate")

WriteFile(last, "timecodesv1.txt" , "part1.framecount+part2.framecount", """ "," """ ,\
"part1.framecount+part2.framecount+part3.framecount-1", """ "," """, "part3.framerate")

[Overdrive80]

Are you referring to TFM(mode=1,output="tfm.txt")?

[bxyhxyh]

Is there any way to encode partially field blended source in VFR.
Can AnimeIVTC help?
