I captured some video from a VHS tape from a movie I made 20 years ago. I broke this up into 22 or so separate videos for the different scenes. Of course, it's at 640X480, since it's from a tape. As a test, I exported one of the clips to a 1080p video, and it came out just the way I was hoping. As in figure 1, it displays just as if you're watching 4X3 material on a widescreen TV. I'm almost finished putting the movie together, and the last scene I'm working on I'm superimposing another video onto it (scaled down and rotated). I was finally done last night, but when I exported again at 1080p, it came out like DVD movies did before they started making them enhanced for widescreen TVs (fig 2).
My first thought was that exporting an already converted 1080p video to another 1080p video Is what did this. But then I remembered that I had already done a test of putting the whole movie together into a sequence and then exporting the whole thing as one video. All those separate scenes were 1080p videos and THAT resulted in a combined video (exported again as 1080p) that had come out correctly just like fig 1.
I kind of panicked after losing that work, so I quickly did a test of taking that same footage from the 640X480 original version that I had thankfully saved, and exported that to 1080p. Was relieved to see that that does still work as before. When I'm able to resume work on it this evening, I'm planning on putting the original 640X480 video in, superimposing the other video, then export to 1080p and hopefully that will come out correctly.
In the meantime, would adding the superimposed video make It lose its correct framing?
Hmmmm... I had made a couple of simple pictures in paint to represent exactly what I'm talking about that I thought I could simply upload (under Insert other media). But the only two choices are Insert from URL - which I could do if I were on my home computer - or Insert existing attachment. But I don't know how to do that second option.
