I’ve rendered(well, I’m rendering) a pretty nice explosion for my game. it’s the kind you get when you blow up a gas station.here:
its going to look like that, but with a brighter core. but anyways, each frame is 640x480, and it’s at least 150 frames, possibly 250. i know a sprite can’t have that many frames, so does the videotexture thing do image sequence, or can a video have a alpha channel.
I have had a lot of success with video textures for similar purposes as you stated. These tutorials helped me tremendously:

However my videos only worked when using the “Add” active face alpha blending, which adds transparency based on color to anything black in the video, so you’ll probably want to render your explosion over a solid black background for the “Add” to work properly.
Hope this helped!

You’ll need to render your videos over solid black, because using the “Add” function for the alpha face blending will add transparency to anything black in your video, acting as an alpha channel.
oh and also keep in mind that video textures do a good job murdering FPS. I have a decent rig, 8800 gt, E6750 C2D, and my FPS drops from 60 to about 50 when triggering the videotextures. I trigger quite a few at once, up to 10, but mine are much much smaller than yours, only around 148 x 124.
Hope this helps!
