1. Black areas around character- Use .tiff image sequences when you render out your animations from Poser. For some reason, Poser messes up the alpha channels in the .psd or other image formats. I always get a good alpha channel with .tiff. In Premiere, when you're setting the Transparency Options for the image sequence, choose "Alpha Channel" and it should composite just fine... 2. Aspect Ratio- There's two ways to mess up image aspect ratio's in Premiere. It looks like you have correctly turned on "maintain aspect ratio" for your imported images. This can be turned on or off from the CLIP>VIDEO OPTIONS>MAINTAIN ASPECT RATIO menu. The monitor window displays the Pixel Aspect Ratio of your current project settings. If you're going to final output to movies you will play on your computer, you want Square Pixels. If you are going to watch your movies on a TV monitor, you need to choose the appropirate Pixel Aspect Ratio for the type of TV you'll be watching (PAL or NTSC). NTSC TV's use rectangular pixels (aspect ratio 0.9) and will appear stretched, or wider when viewed on a computer monitor. If you want, set your Pixel Aspect Ratio to Square Pixels (1.0) while you're editing, but don't forget to switch it back to the appropriate aspect ratio for your final output. Hope this helps
