The Basics of Avisynth - Tutorial

Oct 03, 2011 11:54

There are still people out there, who are very intimidated by avisynth and how to use it to prepare their sources. So I compiled example scripts and tried to break the necessary steps down into easy to follow instructions. Everything is better and more detailed explained in this part of the A&E's guide - The 'A&E's technical guide to All Things ( Read more... )

Thanks for this, it's great. So you do add the RGB32 for downloaded eps? Do you know why? Also if you're just using avi's, there a reason FFmpegSource is it better with the indexing than AVISource?

I started to add the RGB32 to everything, downloaded eps included, after some problems with footage in premiere showed up. It didn't fix my problem back then, but I kept it. The explanation I read in a tutorial was somewhere along the lines that RGB is the colorspace that Premiere can handle best and it can help avoid problems, if your footage is YUV (YV12). So it's not necessary, some even said that you should only add it, if you need it. So you could lose it on DVDs and dled eps.

It's interesting that you picked up on the one thing, I wasn't sure. I didn't had problems with AVISource in the past, in fact, I do all my after-filtering with that clip attribute and I used it in the past without troubles for my source. AVISource is frame accurate, so there shouldn't be a problem on that front.

I'm about to start vidding with .mkvs for the first time, and you have just saved me a ton of trial-and-error time. THANK YOU.

Yay. So happy it works, I had some trouble installing it the first time two or three years ago. But then I had so many trial and error experiences when I first looked into mkv-scripting, it took me ages to work it out. I'm really glad I could help.

AND I just figured out how to disable the audio track. \o/

There are several ways, KillAudio() is one or , false and some clip attributes don't even load the audio without further prompting like FFmpegSource2. That's the reason why I love working avisynth. It's so flexible and neat.

The drawback is that looking back at this three months later and after some comparing on Vid Pub, I already changed parts of my code for the source like skipping the predefined cropping and working with the correct aspect ratio in the project files.
