You'll need to enlarge the fake widescreen about 30% to have it fill the screen.
You can do this by changing Scale in the Motion properties. How you do this depends on which version of the program you're using.
In version 11, this property is adjusted in Applied Effects.
Although, if your fake widescreen seems compressed or squished, you should right-click on these clips on your timeline and change the pixel aspect ratio by selecting Interpret Footage.
Would they appear squished immediately after capturing, or is there a
possibility of this happening during export? That clip /does/ appear
"normal" after capture except for the black frame around it, and the
image within the "frame" seems proportional to the larger "image space"
shown by the project. Do you think it's the pixel ratio that is causing
this? I had a notion that it might be better to try to base the project
on the smaller image and then interpret the larger wide-screen clips
down to it — but I suppose the pixel counts of neither are large enough
to avoid interpolation problems.
If this was a "real" 16:9 video, I'd say it was the pixel aspect ratio.
But your post led me to believe that you were using video that was masked/letterboxed so that it would appear to 16:9.
video that was masked/letterboxed so that it would appear to 16:9.
It wasn't done deliberately after the fact, but your assumption may
still be correct. I believe the other camera is a native standard ratio,
but has an option to record from just the portion of the sensor that
approximates wide-screen. During the capture sequence, Premiere Elements
showed an outline in standard proportions with the widescreen image with
the usual black bars at the top and bottom. I expected to see this on
the actual clip after capturing was complete, but was surprised to see
that the wide-screen image was "reduced" within a black frame instead.
To complicate any understanding of what was happeing, when I captured
the videos (from both the first camera and the letterboxed one), PE
displayed a message saying that my camera settings did not match the
project settings, but I could not find any setting that could have been
changed and the help system was no help. What does that message really
mean? Both cameras were DV cameras, not HDV.
