(With VideoStitch Studio I even load the Hugin <code>.pto</code> file; I thought this should include the crop.) The videos they produce are always a small region of the video inside a sea of black:<br>

  <p>Using either of these two video-stitchers—or any other process—how can I get Hugin-like cropping of my videos?</p>
  
  <p>(The final video dimensions will be very high resolution, on the order of 6k horizontal pixels, so I'd strongly prefer not to say <em>"Just render it extra extra big and then use After Effects to crop out the center."</em>)</p>

Comments.Text: I do know that there are several stitching artifacts, both in the "result I want" image and the screenshot of the video. At this point I'm trying to figure out the proper production pipeline—which software to buy—and so I'm not yet spending a lot of time getting really good control points set up in any package.

Comments.Text: Getting closer: in AutoPano Video I can open the Preview pane, click on the tiny "Authoring" tab in the Timeline pane, and then the projection mode can be changed and I can drag and zoom the view. I still can't set an arbitrary aspect ratio, nor crop asymmetrically around the 'horizon'.

  In my opinion, stitching 2 videos might not be the best option for what you are trying to do as they will be stitched in a full sphere (using a wider lens on your camera might be better)."_ So: VideoStitch Studio cannot produce the output.

  **Summary**: How do I get VideoStitch Studio, AutoPano Video, or any other video stitcher to properly crop an equirectangular or cylindrical projection?
  
  **Details**: I am creating a wide-angle video from two GoPro (120° HFoV each) overlapped by about 50%. The desired end result is about 190° horizontal, 45° vertical. When I bring two (synchronized) video frames into [Hugin](http://hugin.sourceforge.net/) as pictures, I can set up a stitch and projection and crop…
