Avisynth in After Effects

Remember that VFAPI upsamples to RGB by default in interlaced mode. If your script outputs progressive footage (e.g. you do IVTC with Telecide + Decimate), put "_P" just before the extension in the filename. This forces progressive upsampling. So for example bibleblack_P.avs.

Please ignore that. Apparently it only works when you're using .d2vs directly. AVS scripts are converted to RGB24 in progressive mode by default.

I guess this method is now use if you're using raws or any other type of avi ?
But it's nice to know that I can use that method for my next video

. Thanks a bunch.

is there any other benefit by using avs other than saving space? i do all my project in RGB32, a lil alpha helps the effect i think. i usually have 160gb of space for projects, it's enough for most of the time except for CS skill vids.
i never worked with avs, so go back to my first question, what are its benefits? do i loose some of the effect properties by using it?

Yes, you can modify your preprocessing filter chain without having to re-encode any files (as long as you're not changing anything that would affect properties such as resolution and frame rate).

You could edit with scripts with no preprocessing at all (except, say, IVTC and resizing) because it's faster that way, then just before exporting your video, add some preprocessing to make them better-looking and/or easier to compress.

or you can download the God of all guides and keep it open whenever you want to make a script. It's what I did for my first vids with avs.

So did I, but I still had to ask questions when I overlooked the SetMemoryMax option and wound up with black scripts. That was ages ago though, it's been updated since then.

Ripping/scripting DVD footage can be a real pain, but viewing the resulting footage for the first time will amaze you with it's incredible clarity.

After some trying around I managed to import Avs-Files into After Effects (v. 7 pro, but version should not matter).
There are a few things that need to be done right, however, in order for this to work, and some are not so obvious:
- Your AVS-script may NOT contain relative paths. Use absolutes ONLY!!
- Use MakeAVIS (part of ffdShow, you need to enable it during install) to convert your script to a dummy-AVI-file, which can then be imported. However: This does not work for all versions of ffdShow, so you need to try around a bit. The one I am using right now is 20050909. The 20051103 version will NOT work, meaning that you can play those AVI-files using a DirectShow-Player (e.g. zplayer), but you will be unable to open them in VirtualDub or After Effects.
- Audio streams are problematic. It is saver to include a "KillAudio()" line in you AVS-script. If you really need to use an audio stream, you have to activate the option "Store uncompressed audio". If you do not, After Effects will crash as soon as you import the AVI. (This may have been fixed in later versions of ffdShow)

- Other than that it seems you can do just about everything, even after creating the dummy-Avi-file. For example, you can replace the AVS-file later, change the file the AVS-video references, add sharpening effects and use DirectShowSource for your video, so your source can be a WMV-file or an MKV-file with X264. (but you should use those for rendering only because editing will be very slow). You can even change resolution and color space later, but a change in resolution will crop the image.

All this together is not nearly as complicated as it sounds, and it is definetely worth it. Editing with MJPEG instead of a lossless source does not just save you a huge amound of disk space, it is also much faster.

Well, I hope this will help some people!

Please, Please, HELP.

I've asked this everywhere but I didn't get any answer, so please, I'm truly desperate, help me, anyone.

I'm trying to import any type of clip into After Effects, now, for example, an Episode (any) of Full Metal Alchemist, 640x480 with 23,976 fps, receiving, continously, this error.

After Effects error: retrieving frame from video stream. (3)

( 53 :: 34)

Please, anyone can help me? I'm really desperate I don't know what can I do.

I think that probably this can belong to an Avysinth solution but I tried to make what it's suggested here, without changing, sadly, nothing.
