I have returned from Summer Camp and I am back.  I know I haven't been posting pictures lately, but soon I'll be ready.  The hardest part about mixing the audio and the video of my movie is that I "borrowed" the sound effects from Bejeweled 2, and that those sound files, .OGGs, weren't meant to operate on anything except the game [2018 update: whoops; turns out .OGG is a more common audio format than I'd thought, so I must have run into a separate issue, or else it was just too obscure for Blender's notice at the time].  However, I recently figured out that I may have been doing it right some of the time.  You see, when I made a video with only audio/only visual, I think I created both at the same time--two files, the sound and the sight.  I think I'll be able to mix those together without much problem at all. By the way, another Non Sequiter ... Ι γαν σπελλ Βλενδερ ανδ Σγυλπτρισ ιν Ενηλισθ γθαραγτερσ! Blender and Sculptris in English...

After taking quite a long time studying my book, digressing on world domination schemes and trying more combinations of codecs, I finally got my answer on a forum I'd posted my question on.  The answer was that I could just insert the sounds after I finish rendering.  He also said that the error message means that I've chosen "bad parameters." I have no idea what he means, although I may have a small idea on how to fix it... but then again, I'll probably end up going with his suggestion: put in sound later (I've finished the animation).  There may be yet another long pause since I'm leaving for summer camp soon--a non-computer activity. However, now that I've mostly solved the problem (thanks "Stiv"!), I'll try to post more frequently. On another note, I got a Bamboo pen & pad for my birthday which (when I figure out how it's used) can dramatically improve using Sculptris, and may help with Blender too!

Very busy Summer.  Friday's storm went up, my computer had no electricity, I'm still working on turning our lightning rod into a power supply, and I've still not found out the correct codecs (forms of encryption) for my animation.  However, I have an advantage now: I have the Blender for Dummies book (which I've looked to several times in a row now--don't tell anyone) and I should have a bit less trouble here.  Any other Blender users can also comment all they want so I can read them and then delete them before anyone notices .  Hope to fix it soon!
