Hi, Ricky599!
Okay, I assume you're working with 4:3 aspect ratio clips, so the black bars will be vertical at either side of the image. Here's what to do:
1] Drop the video onto the timeline, you'll get a warning of Aspect Ratio Conflict(assuming your Power Director 14 is already set for editing in 16:9, this can be confirmed in a little indicator up near top-left of screen(near the cog wheel) Click "No" on the Conflict warning.
2] With the clip on the timeline, you'll see in the preview window, black bars either side of the image, Right-click on the clip in the timeline, scroll down to "Set Clip Attributes", another panel will appear, "Set Aspect Ratio" will be at bottom of that panel, left-click on "Set Aspect Ratio".
3] The next window you'll see is "Clip Aspect Ratio Settings", select "The Aspect Ratio of the video is 4:3", this will then give you two options, a) stretch clip to 16:9 aspect ratio, or b) use CLPV to stretch clip to 16:9 aspect ratio. Choosing the latter will retain proprtionality of the clip(won't make anyone appear to have "raided the refridgerator" LOL).
If however, your clip might already be in 16:9 but you're getting black horizotal bars at top and bottom of the screen, you can correct this again using step 2(set clip attributes, then set aspect ratio. You may need then to select "neither 4:3 or 16:9" which should then stretch your video vertically to remove the black bars at top and bottom of your secreen.
Cheers!
Neil.
