When I click on Edit in nothing happens

You need to use Autopano Pro/Giga alongside Autopano Video.
This is specified on both the product page on the main Kolor website and the online store. You can download them from our Downloads Center.
If you already have Autopano Pro/Giga installed, read I have Autopano Pro/Giga installed but nothing happens when I click on Edit?.


I have Autopano Pro/Giga installed but nothing happens when I click on Edit?

Your ".pano" file extension is not linked with Autopano Pro/Giga anymore, you should have the same problem when you try to open a ".pano" file for your OS explorer. To fix this:

  • on Windows
    • Right-click on a ".pano" file -> open with -> choose default program -> select the last version of Autopano Giga
  • on Mac OS
    • Right-click on a ".pano" file -> open with -> other -> select the last version of Autopano Giga and check the box "always open with".


Why is there a yellow warning sign in the cameras timeline?

This warning sign Icon attention.png is due to the activation of the smart cutting, and the smart cutting is not compatible with the camera interpolations (the transitions and the motion compensation). This cutting mode is recommended only when you have a static camera and a pretty static subject/scene.

You need to change the cutting mode to ISO. this can be set in the weighting section of the render window of Autopano Video, and also in the preview tab of the Autopano editor.



With the rendered video

My synchronisation is good but it looks unsynchronized/there are seam issues

This is propably due to the rolling shutter of your cameras. The rolling shutter results in a little desynchronization between the top and the bottom of each frame. And when you stitch two videos subject to this "internal desynchronization" it gives you the illusion that your videos are not synchronized.

This side effect of the rolling shutter is accentuated in very bright light environments (sun light), one of the solutions is to limit the light entering in the camera lenses. For that you can use a ND filter. Using such filters will also reduce the bad capture effect of plane propellers.


Why do I get an error message when I try to view my video?

The "Assertion failed at core/pushencoder.cpp(429) - Invalid state" error is sent by the encoder meaning that your settings don't fit in a "standard MP4 preset" or that your output folder doesn't exist.
This also could be due to a high FPS, a bad size (too large or not multiple of 16), a too large bitrate... You also have to make sure that the framerate you ask for fits into the output standard (PAL or NTSC). For the solution see our Troubleshooting page.
