Frame size for export.

Hi All

I'm puzzled (again...). I've been exporting ex-Super 8 cine in 1440 x 1080p format (4:3 MP4), and as expected I have black sidebars when played back on a 1080p television; similarly with 720x576p. However, when I export the same clip in 1920x1080p 16:9 (MP4) frame size, I find I have the same black sidebars and an apparently identical picture. I had expected to fill the screen with a somewhat distorted picture, but that didn't happen. What am I missing here? MEP Plus 2018.

Thanks

Richard

I don't think that we have discussed this here, but I'll put the question out to all of you. If you output to a lower resolution, like DVD quality, what happens when you watch it on a full HD TV? It goes full size, does it not? Does this mean that the video is upscaled anyways? If so, then what is the difference between that and using the higher resolution for editing and exporting?

Yes it is upscaled always, otherwise you would have a little rectangle in the middle of your screen.

The reason some of us feel that it just as good or better to not upscale in the export is because we feel the hardware upscaling and algorithms in modern TVs may do a better job than the software encoders in MEP /VPX.

You would need to check this out on your TV with an identical video export using both scenarios.

My 4k LG 55" TV does a great job at upscaling. To my untrained eye 😉, 720x576 ex-VHS looks as good as the video played on my computer screen, which is only 2ft from my face.
