vibrating up and down video after exporting H.264

Question

So I've looked at a number of posts describing similar bouncing issues and I've tried the solutions posted to no avail.

Here is a video of what I'm talking about.

The source video is H.264 and was created in adobe premier. I just edited the sound down a bit in one portion, and then exported it and now it does this weird vibrating thing.

One post I found said it was the bitrate, so I turned it all the way up. Another said it was that the video wasn't deinterlaced so I did that, and still nothing.

Anybody have any idea how to make this look normal like the source video?

Your media & sequence are interlaced, your export is progressive.

Interlaced media has two half-frames per frame, each one has every other line of the image horizontally. They alternate which is shown as in the odd-numbered lines go first and the even-numbered lines second ("lower first") and we "see" one image. Progressive means that each frame is a complete frame, showing all the horizontal data lines.

You're not getting a good de-interlacing here. Partly, you've got a 29.97i (interlaced) sequence exported to a 24fps output file. Between the frame-rate and de-interlacing, you're getting your problem. There are some tutorials on dealing with de-interlacing issues on the Adobe websites, you can search for them, but ... sorry, I don't have the links at hand right now.

Your source video, prior to editing, does not exhibit this problem?

Does it exhibit this problem while editing in Premiere Pro?

Please post a screen shot of your Export Summary for the Export Settings Pane, like this example below:
