Video Compression

[Eretria-chan]

Hi, I have a little question or matter that I could use a little help with.
I'm trying to compress all of my anime videos to as compact as possible! Curently I'm using x264. However, to make it as compressed as possible, I've looked into options to use post processing. The video files are meant to be plaed only on my computer, which have a Athlon XP 3200+ I think. 2.2 GHz in any case. But I don't know that much about post processing, only that ffshow's deblocking is very good, but sometimes not good enough.
I dunno, but could anyone help make it even better - like an avisynth script? I just try to get it as small as possible with any settings, so...

As for audio.... that's another matter. I have used nero's HE AAC encoder, but recently I found out that there's a better one out there. I haven't really used it so I could use some help to use it to compress the audio within the video.
I have quite some files to compress too, so, batch-processing will certainly be welcome.

Can anyone help me out a bit?

I find your questions a bit vague..

Compression is done when you encode the video, and post-processing is done when you decode it, so I am not sure I understood what you meant by "However, to make it as compressed as possible, I've looked into options to use post processing"? It doesn't make sense to me.

In a nutshell - x264 for anime is a good choice. Using AVISynth filters, you can make the video better (look in the AVISynth forum for helpful threads). I didn't understand what you wanted reg: audio, but there are many choices - AAC, MP3, OGG - try them, test them, use the one you find satisfactory. Also read the audio forums. Many encoding tools offer batch processing..VirtualDubMoD, AutoGK, GK..

Post processing, With it I mean things like deblocking and other enhancement filters such as avisynth has. This would make me able to use even lower bitrates.
As for the audio, not doubt it is aac that currently offers best compression, but I am unsure of how to use it exactly.

Possibly, but don't count on it removing all of the blocks and rings etc. Using a higher bitrate (around 700 to 800 Kbits/sec) will do the job most of the time.

This, I know :) But I like to try. I'm just not sure what I should use to achieve a good effect.

in h.264's case, deblocking strength can be set encoder-side, and the inloop filter will make sure it's applied as effectively as possible. of course, that's just the theory. at any rate, tweaking the deblocking on the encoder-side will help you.

perhaps a mild temporal filter on playback (maybe a strengthened version of didee's "soothe") can ease some of the flicky-smudgy blocks that x263 can produce on certain types of video (pulsing smoke for example).

Oh, I wanted some feedback on my latest experiment:

Some scenes do look a little blocky. But I suppose usage of zones could fix that. Shame that RealAnime does not support them and I do not know the settings it uses for compression. Otherwise, do you think a low bitrate matrix might help a little? I have Nero installed, so playing it back should be possible. Is it possible to use another matrix in the VFW? This clip was encoded @ 200 kbps, maximum in-loop filter strength and 32 kbps HE-AAC audio. I'll maybe do the audio better compression, but I can't seem to get in below 16 kbps :( Oh well.
