Thanks for coming back to me.
This is wahat you posted:
If you can get PAL footage for your .mov fine. If not, and you are left with the NTSC counterpart, here is the plan (grand plan or dud). Let us see
Import your 640 x 480 @ 30 frames per second into Premiere Elements with the NTSC DV Standard project preset (you will probably have to set the project preset yourself manually before you import the file...to do that File Menu/New/Project, change the project preset to NTSC DV Standard, and, before exiting the new project dialog, make sure that you have a check mark next to "Force Selected Project Setting on This Project". Then import your file with Add Media/Project Assets.
In Project Assets, right click the thumbnail for the file there and select Interpret Footage. In the Frame Rate section of the Interpret Footage dialog, dot "Assume this frame rate" and fill in 25.00. Leave the rest as is which should be with Pixel Aspect Ratio = Square Pixels (1.0).
When you are ready to export, give the following a try:
have Presets = PAL DV
under the Advanced Button/Video Tab set
Video Codec = H.264
Frame Width = 768 pixels
Frame Height = 576 pixels
Frame Rate = 25 frames per second
Field Type = Progressive
Aspect = Square Pixels (1.0)
For now leave everything else as is.
At playback, check the quality of the video and audio as well as flow of the motion.
We will be watching for your results.
Is that what you mean?
I have been researching your question further since I believe that what you are encountering goes to players rather than the specific video files that you are producing.
Windows Media Player has a long history of users not getting a video that fills their screen even when the player is set for "Full Screen". I have been reading through various fixes and still trying to figure out which ones if any really address the matter.
Have you looked at your H.264.mov with QuickTime player. Of all the choices for your H.264.mov, I think it probably gives the best presentation. I am not sure if the VLC Media Player offers any answers in this matter.
Here is some of the things I have been coming across
