Raw WMV3 to h264, without losing quality. How?

(1/2) > >>

sapsa:
I was lucky to get one of my *rare* childehood anime that I watched.
The problem is that the whole collection aint that big (60) but It waste alot of space 25Gb.
I would like to make those AVI + WMV3 to MKV + h264 if i get same quality with less space needed.

I'm not into this stuffs, I used automkv programs to conver Fraps to mkv h264 with great results. I was hoping someone can guide me if there is a point for making this. Those are RAWs.
If its important there's no subs.
I provied info about files:

Get either 32-bit or 64-bit patched build (depending on your OS) & unrar it to the folder with the original files.

Open command prompt, go to the folder and type these.

--- Code: ---
x264 --preset veryslow --tune animation --crf 18 --acodec copy -o outputfilename.mkv inputfilename.avi
--- End code ---

I will read about those preset's (i'm unfamiliary with those).
I got some spare time. first file for test puropse: 2:30h O.o

Xiong Chiamiov:
Since you're converting lossy -> lossy there will be a loss in quality.  You can probably make it an unnoticeable difference, though, by using rather high settings, which is why that conversion's going to take so long.

If it feels too slow use a faster preset. Also you can modify the crf if you want; bigger number gives a smaller with lower quality, smaller number gives a larger file with better quality.
