Hi mungy,

The first thing you need to know is that mp4 will never show up as a codec in Muvizu. Its not a AVI codec. You can convert your AVI video to MP4 later though.

Have you tried installing XVid as a stand-alone codec? I've often found it doesn't show up with K-lite codec pack installs and so, these days, I just go to http://www.xvid.org/Downloads.15.0.html and install the stand alone version.

If there are other codecs you want to use, could you list them one by one and we'll try and help you with them individually.

Let me know how you get on.

Cheers,
Jamie.

iYUV is a pretty good codec, used to use it myself until I went all uncompressed. If that's still producing files that are too big, your only other option seems to be to use the 32 bit version of Muvizu, which always supported more codecs than the 64 bit version (currently my Muvizu is showning just 2 codecs - msv1 and uncompressed, that's it, despite having the latest k lite pack). And I hadn't realised k Lite had merged their 64/32 bit codecs together in one pack these days, so that's one less complication at least! If you're not going to produce sets that exceed 3gb in your PC's memory, there really is no benefit to running the 64bit version of Muvizu anyway. And you can have both version installed side by side since they live in different places on your C drive. Can't hurt

Hi Mungy,

May I ask what resolution you are trying to render out at?

Some codecs will only do up to a certain resolution, as such, you may have all the codecs you need, it's just that the codecs won't support the resolution you are going for.

Here is what we have on codecs from our Wiki: http://www.muvizu.com/Wiki/wiki/78/codecs

The K-Lite pack includes the 32 and 64 bit codecs these days, so no need to download one or the other.

Try rendering out at a lower resolution to see if you get more codec options and increase as necessary.

Hope this helps!
