My latest track is progressing on YouTube like a car without tires. But Nicovideo has a whole Vocaloid section. It's useful - last time one person thought my music is decent so they actually streamed a part of my first Vocaloid track (Other 19 tracks aren't Vocaloid).

BUT today, as I finished uploading my latest track on Nicovideo, I noticed nothing was going on. I went to set the thumbnail, but they weren't offered. I clicked under them to reload them, but Nicovideo gave me an error message about the inability to generate thumbnails. So I chose one of the empty ones and confirmed my upload. Error message said it cannot generate the thumbnail. Video is gone, it all goes to nothing. Gotta do it all over again.

And then there's been hours reuploading it, even making a new render... Am I doing something wrong, or is it just a bad web service?

Here's the codec information. Same as the one that successfully uploaded 6 months ago, only smaller. Please help.
