Moviestorm Quits At Render

[Overman]

Since the update to 1.5.x (from 1.4.x), I can't seem to render to either WebM or HuffYUV. I render from the Custom tab, and regardless of resolutions and framerates I've tried, when I have a WebM or HuffYUV selected for the codec, pressing the button to initiate a render just closes the application. Or so it would appear (the window is gone). I've noticed that if I then relaunch Moviestorm, it seems to think it's still running. But from all appearances, it's closed.

I can successfully render to image sequence right now, which fortunately gets me squared away for tonight because I didn't need audio. But naturally I want to get regular video rendering working.

I've been able to successfully render to HuffYUV from this same computer a couple months ago when I was on 1.4.x, so I think I've got the right codec in place? WebM I've never dealt with, I'm not sure if I'm supposed to install a codec for that to work or not.

Is there a step I'm missing, or some files I'm missing, since 1.5.x? Or does anyone know why this "crash" would be happening?

Machine is Windows Vista 32-bit, fully patched, and has been my working Moviestorm machine since WAYYYYY back in the day. 4GB RAM, nVidia GeForce GTX 280.

Thanks very much!
