Difference in MP4 Properties
Doing a cross comparison analysis between the original MP4 I downloaded to that where I rendered into a new MP4. Wondering if I use the new Mp4 if that will provide a sharper quality since it is already in 1920×1080 format when rendering to m2v????

If I’m understanding you, you downloaded an MP4,from the internet? Then made it into another MP4? Why? It was already an MP4. What is the resolution of the first one? Making a new one with a higher resolution is not going to improve the quality. Also every time you render a video, it takes a re compression hit.

As Danny pointed out, re-rednering low resolution video to a higher resolution does not improve the quality and may actually decrease it because the render itself is using a lossy codec.

From the JPEG I had posted with it, the original showed the resolution, data and etc. In the experiment, redoing into a 1920×1080 factor, everything increased in the cross comparison analysis which also made it bigger. Then using the new MP4 as a source to do in m2v may have a difference.
