How to correct faulty aspect ratio
Let's say you made a mistake and encoded your vid with the wrong aspect ratio (AR), or you downloaded an .mp4 with a faulty aspect ratio, like this:

This was made from a standard 4:3 PAL source, but it was encoded at 16:9 NTSC (anamorphic), so it looks squashed. The image is much wider than it should be.
Thankfully, you can correct the aspect ratio without re-encoding.
Follow the instructions in post #8 above until you get to the MP4 File Creation screen:

Click on the .h264 file to highlight it, then click Properties
In the Properties dialog, click the Pixels Aspect Ratio dropdown box and select 4:3 PAL (or whatever the correct AR should be for your vid).
Click Ok

Back on the MP4 File Creation screen, click Next
Continue with the instructions in post #8 from the first screen that reads "Running process".
Here is the same frame before and after:
