Filtering help needed

[x264]

How do i replace some frames of a DVD with other frames taken from another DVD?. Which filter should i use for doing this?

[Selur]

basically you would use trim(..), see for example: http://avisynth.org/mediawiki/Shared_functions/EditingFunctions
Stickboys RemapFrames-functions might also come in handy.

Which software should i use to encode a tru-hd audio file?

[x264]

What should i use for lossless compression of a 24bit dts master audio track?

[x264]

How do i find the match failed frames after using TIVTC?

FLAC should be able to hold 24bit audio without loss (assuming the decoder you use to feed it with decodes it properly and not only the dts core)

> How do i find the match failed frames after using TIVTC?
From what I understand TFM always produces a match, problem is sometimes the match just isn't good.
Reading http://avisynth.org.ru/docs/english/externalfilters/tivtc_tfm.htm thoroughly might be a good idea.

Can i use Dolby media encoder to compress a tru-hd audio file into the flac format?

[Selur]

No, the Dolby Media Encoder is ment to convert wav to Dolby Digital Plus, Dolby TrueHD, Dolby Digital or MLP Lossless™.
It does not support converting any of these formats into something else.

mode -

Sets the matching mode or strategy to use. Plain 2-way matching (option 0) is the
safest of all the options in the sense that it wont risk creating jerkiness due to
duplicate frames when possible, but if there are bad edits or blended fields it will
end up outputting combed frames when a good match might actually exist. 3-way matching
+ trying the 4th/5th matches if all 3 of the original matches are detected as combed
(option 5) is the most risky in terms of creating jerkiness, but will almost always
find a good frame if there is one. The other settings (options 1, 2, 3, 4, and 6) are all
somewhere in between options 0 and 5 in terms of risking jerkiness and creating
duplicate frames vs. finding good matches in sections with bad edits, orphaned fields,
blended fields, etc...

Mode 7 is is not one of the normal modes and is specifically for material with blended
fields that follows a specific pattern. Mode 7 requires linear access to work correctly
because what match/field are used depends on previous match decisions.

Possible settings are:

0 = 2-way match (p/c)
1 = 2-way match + 3rd match on combed (p/c + n)
2 = 2-way match + 3rd match (same order) on combed (p/c + u)
3 = 2-way match + 3rd match on combed + 4th/5th matches if still combed (p/c + n + u/b)
4 = 3-way match (p/c/n)
5 = 3-way match + 4th/5th matches on combed (p/c/n + u/b)
6 = mode 2 + extras if combed (p/c + u + n + b)

How do i know which mode i should use with TFM?

[Selur]

try&error (that's what 'preview' is normally for)

99% of the time the default is fine and you don't have to choose anything. If you begin messing around with the different modes you can seriously mess up the output.

[x264]

Ok. Is it necessary to postprocess? i have noticed that sometimes the postprocessor deinterlaces the good frames.

[Selur]

Normally it's good to stick to the default value.

Yes, the post processor sometimes makes errors:

[Selur]

The main point of filters having default values and different options is to:
a. normally use the default values
b. if the defaults fail in some way or another, change the default values
-> there is no: 'use always this setting'

How do i calculate the VMetric value for a DVD from both sides in yatta?

[Selur]

No, clue never used Yatta and I'm not planning to.

[x264]

I would like to fix the match failure's with yatta.

[Selur]

Anime forums (in example: http://forums.animesuki.com) are more suitable places to find Yatta user, since normally only animes are that messed up that Yatta is needed.

[x264]

My account is disabled for some reason. I can log in but i cant post.

[Selur]

May be you are lucky and your thread here will be read by someone who:
a. knows Yatta
and
b. has the motivation to help with Yatta problems
I fail at a.

Can someone explain what a lossless pass is?

[Selur]

What is unclear about that?
lossless pass = a pass where only lossless output is created
(depending on the context, the material might be converted to a lossless format or just analysed and not converted/modified at all)

For heavy filtering and 2pass encoding, it might be a good idea to first encode the output to a lossless format and then use this output as source instead of running the filtering path 2 times (during 1st and 2nd pass).

[Selur]

regarding Yatta, it might be a good idea to read the help: http://ivtc.org/manuals/Yatta.chm
(you might have to unblock it if it shows just empty pages -> http://weblog.helpware.net/?p=36)

I have a DVD which is soft telecine, after using force film on it i see combed frames. How do i fix this without using vinverse? The fields look shifted.

[x264]

How do i do a lossless pass for this script?

DGSource("C:\Users\Abhijith Nair\Desktop\New folder (2)\VTS_01_1.demuxed.dgi", fieldop=1)
trim(0, 33587)
crop(8,0,-6,0)
Dehalo_alpha_mt(ss=3.0, darkstr=0.6)
Dither_convert_8_to_16()
SMDegrain(lsb=true, pel=4, subpixel=3, refinemotion=true, thSAD=250, truemotion=false, lsb_in=true, lsb_out=true)
Dither_Quantize(10, reducerange=true, mode=0)
Dither_Out()

As it's not 100% Film, there's always a good chance there are interlaced frames remaining. You can IVTC it after making the D2V using Honor Pulldown Flags and:

TFM(D2V="Movie.d2v")
TDecimate()

You can open the D2V in Notepad and look at the bottom and if it's pure soft telecine it should say 100% FILM.

NTSC films don't have field shifts, not in the sense that PAL films on DVD or real progressive 29.97fps might.

How do i do a lossless pass for this script?

One way (but maybe not the way you were looking for) is to open the script in VDub and save it out using a lossless codec (Lagarith, HuffYUV, UT Video Codec, etc.).

[x264]

TFM(D2V="Movie.d2v")
TDecimate()

How is this different from setting the force film option?

[manono]

TFM(D2V="Movie.d2v")
TDecimate()

How is this different from setting the force film option?

You could always read the TFM manual and find out for yourself what the D2V setting does. I already told you one difference:

You can IVTC it after making the D2V using Honor Pulldown Flags...

It's not a flag-reading Force Film, but an IVTC of the hard telecined portions and, in effect, a Force Film of the rest.

Heck, you could even try it out and see if your interlacing is gone. What a novel idea!

[x264]

Should i change any of these settings before saving the file as .avi?
