AviSynth Q&A - Page 3

I went with “broadcast video” — I think that’s a good description of the filters’ target.

On top of that, I gave the list a fairly general edit. Feel free to change any of it back if you don’t like the alterations, or you can just ask me to fix it.

The docs refer to YUY2 and YUV without explaining their relationship. Should we wait until YV12 is generally available before fixing that up?

Thanks for your improvements!

We can already start with that. I don't know when Sh0dan is planning the first beta release of v2.5, but the docs should be adapted at that time.

Wilbert · 20th December 2002, 10:54

The past days I did a major update of the faq. A very brief summary:

1) included most of the YV12 stuff from the YV12 faq:
- Q7-Q11: how to encode in YV12?
- Q16: about avs2avi
- Q35: list of all the v2.5-plugins

2) Q32: Improved description of RGB/YUV colorspace.

3) Q31: DirectShowSource and VobSub.

4) Q27-Q28: MP2-audio

5) Q34: Added v2.0x plugins, but I forgot which ones.

Regarding to www.avisynth.org I added descriptions of new internal filters which will be available in v2.5. (Except ColorYUV, because I don't know that filter very well.)

sh0dan · 27th December 2002, 01:41

ColorYUV information has been added!
Also modified some information on SwapUV and sample conversion.
Also limiter only accepts yuv data.

Antimon · 28th December 2002, 19:14

there is a problem with teh q&a

vob-files

Make a DVD2AVI project file and save it (filename.d2v) and load this clip into AviSynth:

LoadPlugin("d:\mpeg2dec.dll")

mpeg2source("d:\filename.d2v")

or

download the [MPEGdecoder (by Nic)] and make the following script (no audio support yet):

LoadPlugin("d:\MPEGdecoder.dll")

mpeg2source("d:\filename1.vob+d:\filename2.vob")

acording to the mpegdecoder i downloaded today mpeg2source is not a recognized command, if i make it mpegsource it works with vob's and likely all examples you give

Wilbert · 29th December 2002, 00:59

Thanks, I will change that soon!

sh0dan · 5th January 2003, 17:11

I've been doing some updates on avisynth.org - and I'm beginning to love wiki very much.

I would encourage everybody to start creating some guides. Topics could cover:

MPEG2 -> XviD
MPEG2 -> VCD / SVCD
AVI -> MPEG
DV -> DVD
CleaningCaptures
CleaningDV
AdjustingColors

Edit: Hmmm.. about the wiki love. Is there a way to undo changes completely. I mean - the hsitory allows you so see what have changed, but it doesn't show any formatting. Is there a way to make wiki give you the unformatted text, when some dopehead has deleted it?

HarryM · 8th January 2003, 09:43

@Sh0dan:

Can you implement into Avisynth 2.5 fast version of ReduceBy2 (maybe FastReduceBy2 named), based on simple 2x2 matrix resize (such like in Virtualdub)?

@Virtualdubmod makers:

It is possible make any modification, which can allow insert AVS script direct into video capturing process?
Pure Virtualdub allows only own RGB processing at capturing process (it is dammly slow)...

Script for on-fly capturing into XviD (full in YV12) can be (e.g.):

(YV12, 768x576 px PAL)

ReduceBy2
TemporalSoften(1,5,6)

(YV12, 384x288 px XviD)

I think, that actual CPU's are competent fast for implementing this...

Just click on 'edit document'. Then choose 'view history'. Then click on the date that you think is the last correct one, usually one with a known author (Like sh0dan, hakko504, wilbert...). Then you (re-)save that document and voila.

sh0dan · 8th January 2003, 10:37

Nice! Thanks!

I seriouslu doubt it will be any faster than the 121 matrix currently being applied, and quality is more exact.

scmccarthy · 8th January 2003, 15:25

@sh0dan&HarryM

Yes, a 121 kernel sites the resize over the right line and a 22 kernel would shift the image a half line. It's analogous to the siting issues for chroma.

Wilbert · 23rd January 2003, 18:27

I renumbered the questions in the faq. I'm sure you will get used to it

This way it is much easier to add and delete questions!

What I'm also sure of is that I broke some links on www.avisynth.org. I will restore them and add some other stuff tomorrow.

cweb · 25th January 2003, 15:26

I should write a guide on MPEG2 to KVCD.

hakko504 · 25th January 2003, 15:33

I have started with the MPEG2 -> AVI guide, and I intend to cover DVD-decryptor(done), DVD2AVI(done), GordianKnot(done), manual encodes with DivX 3.11, 5.02, 5.03 (Mostly done, minor adjustments might be necessary).

[edit 030209] Xvid guide still not done. I'll take a look at it, but I still might need help with it. I also added a quick guide for DivX5Enc, and I've asked Dolemite to write something about DVX.[/edit]

Wilbert · 7th February 2003, 17:16

I added a bunch of stuff to the faq last week:

added Q1.13: I got the message "LoadPlugin: unable to load "xxx" is not an AviSynth 1.0 plugin ?
added Q1.14: How do I know which colorspace I'm using at a given place in my script ?
added Q1.21: Where can I find VCF2AVS ?
Restyled Q2.10, added: how to open ATSC/PVA transport streams in AviSynth. I hope Nic/Tom will correct it if necessary
updated our filter list in Q3.3 and Q3.4.
Several other little things.

Wilbert · 8th June 2003, 21:34

I reorganized the faq:

removed outdated stuff related to old AviSynth/DVD2SVCD/TMPGEnc versions
replaced link2 by makeAVIS
added the PluginPace frameserver (Vegas, Premiere, Ulead -> AVS)
removed chapter 5
a lot of other minor improvements

Loul · 21st June 2003, 21:46

Looks like some idiot erased the faq.

http://www.avisynth.org/index.php?pa...nd+colorspaces

Well the good thing is that we can still access the old pages through http://www.avisynth.org/index.php?page=RecentChanges

Edit : looks like wilbert repaired it all, thanks !
