If your videos are to be shown on widescreen HDTV, then I would think that you would want to create Premiere Elements HD projects.
DLSR 1080p30 @ 29.97
With the photos imported at 1920 x 1080.
Where did you come up with 1050 x 750? That should be 1000 x 750.
Yes, sorry that was a typo it should have read like you said "1000 x 750"
Okay I can do like you suggest for the 16:9 with the 1920 x 1080 but when I do that to my original image is still distorts and widens (fattens) the individual. Is there a way to prevent that or is that just the nature of that ratio?
When you use 16:9 photos, output 16:9, and you have a 16:9 TV display setting, you should not be running into aspect ratio issues.
Have you explored all the viewing options on the HDTV....one contributor in a recent thread claimed to get the desired viewing result
with an option called Zoom.
If you have 4:3 originals, resizing to 1920 x 1080 16:9 is not good enough. You need to include cropping resizing to the task.
Photoshop Elements Editor File Menu/Process Multiple Files/ only does batch resizing - no batch cropping. On an individual basis,
you could use the Photoshop Elements Editor Crop Tool (see options bar for setting up for a 1920 x 1080 crop/resize.
There are 3rd party softwares that you might explore for batch crop resize. A frequently mentioned one is IrfanView.
If you have Microsoft Office Picture Manager, that might be another possibility.
Just some links about the crop resizing
