Premiere Elements 11 on Windows 8.1 32 bit.
(Please remember that Premiere Elements 11 is only a 32 bit application when running on Windows 8.1 32 bit, and you could be running into resource issues depending on the size of your projects. But, we will put that thought aside for the moment.)
With the assurance that you have the latest version of QuickTime installed on your computer with Premiere Elements 11....
If you are importing 1920 x 1080 @ 25 interlaced frames per second, I think that we are in agreement that the project preset should be
PAL
AVCHD
Full HD1080i25
For the export, let us look at the following and then let us know what that looks like and sounds like
Publish+Share
Computer
MPEG
with Presets = HDTV 1080p25 High Quality
This will give you a MPEG2.mpg file 1920 x 1080 @ 25 progressive frames per second.
Your interlaced source will be deinterlaced by the program. For this try, do not bother with Field Options for the Timeline file.
Also, MediaInfo does include Scan Type Interlaced or Progressive, but you have to be in the Tree View.
Please see View Menu/Tree View for the comprehensive list of video and audio properties for the file.
Please consider. We will be watching for your results.
Thank you.
