until a certain EXACT frame (it always stops in the same frame), on wich it trows the infamous error message. All went well, and MMD liked the video file. If your HDD is mechanical, and is slow, maybe it doesn't feed the video data fast enough to MMD, and in some point it trows the AVI error.įor example, for an MMD video that I'm doing, I've used the very famous UtVideo codec to encode a background AVI file for MMD. MMD doesn't like videos with high bit-rate MMD doesn't like big video files, like RAW AVi format. Therefore, if you don't have the same codec that was used to make the AVI video, you won't be able to play it.If you are obtaining a "Cannot load AVI file" error at a certain point using an AVI file, I have some theories: Encoding and decoding is performed using a "codec." A codec, which is actually an abbreviation for "Coder / Decoder," is a small program that allows your media software to pack and unpack video files.

Basically, the data was compressed a certain way, and your computer needs to unpack it in the exact same way for it to be usable. To play back a video file, your media player software will have to decode the data using the same algorithm used to encode it.This means that it will be compressed using a certain algorithm to reduce it to a manageable size. When raw video data is saved into a computer file, it needs to be encoded. The first step to understanding why AVI files can be so fussy is to understand what encoding and decoding are.It simply "contains" the data in a shell that will be familiar to the user and to your software. AVI is what's called a "container format," which means it doesn't specify how the video and audio contained within it was encoded. Familiarize yourself with how the AVI file format works.
