Software troubleshooting

On Mac

Restore default settings

Here is how to completely restore the default settings:

  • Delete the preference files -
    • Close Autopano Video
    • Go to the Finder menu > Go
    • Open the Library
      • OSX 10.6 and below: the library is displayed and available directly on the menu
      • OSX 10.7 and above: the library is hidden, hold Alt key to display it on the menu
    • Go to the Preferences folder
    • Find and remove the files called com.kolor.autopanovideo***.plist
    • Empty the recycle bin
  • Delete the cached preference files - Certain MacOS versions cache their .plist files, which stops the settings from going back to default. If your settings are not resetting, follow these steps:
    • Launch a command terminal (Applications > utilities > terminal or search for Terminal on your Mac (it should be the first result)
    • Type or copy in this command (in bold): defaults delete "com.kolor.AutopanoVideoPro22" where 2.2 is the version of Autopano Video Pro that you have installed
  • Check the original preference files haven't been restored by going back to your library, remove the remaining .plist files if they were recreated.

On Windows

Multiple GPUs

If you own an integrated Intel GPU and a nVidia card, you can select which GPU to use with Autopano (or any other application) on Windows:

  • Right-click on your Desktop
  • Select nVidia control panel
  • Then select Autopano Video to be used with the nVidia GPU.

GoPro Cameras

Recovering your files

There is an "SD error" on the GoPro , accidentally deleted some important files or your SD card is simply unreadable ?
There is a powerful solution for you : Test Disk.

Troubleshooting - Using the software

When I click on Edit 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 or other software opens 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 from 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".

Saving changes in Autopano does not update in Autopano Video

There are a few things to check that can and will cause this problem:

  • Are all the source videos in the same folder? And the project file too?
  • Is there any space or special characters in the folder name / video name / project name / filepath?
  • Are you working on a network drive?

Also make sure you fully understand how Autopano Video works :

  • Are you in the correct tab for applying the changes you want :
    • If you need to change the stitch/stabilization/color correction ... => stitching tab
    • If you need to change the projection/crop ... => authoring tab

For instance on the screenshot below trying to change the projection in APG while being in the stitching tab in AVP will result in no changes being applied. (see red circle on screenshot below)

  • Are you trying to edit when you are located in a transition between states?

Indeed, only states in blue can be modified in APG. That is to say that on the screenshot below, only changes in colors and stitch made in APG are going to be applied to AVP. Changes related to masks or the horizon will be discarded since the current moment is not located to a blue state in those timelines.

On the screenshot below, only changes regarding stitch or masks can be applied to the AVP project because those two tracks are currently in an editable state (blue) . Other changes related to horizon or colors will be discarded since the current time of edition is located on a transition for those items (green)


Changing the projection or cropping does not take effect in Autopano Video

You need to be in Authoring mode to change the projection or to crop your video.

Autopano Video resets after saving in Autopano

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 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.

Assertion failed at core/pushencoder.cpp(429) - Invalid state

Assertion failed

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 exists. 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 fit into the output standard (PAL or NTSC)

The first thing to check is that your output folder exists and that you have the write rights on this folder. You also have to make sure that your settings fit in a standard level of the MP4/h.264 norm, see the section "Levels" of the wiki article: http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC

Known issues

This page lists all the known issues with Autopano Video v2.2.0 only. It has been corrected in version 2.2.1

If a problem is not defined there, feel free to contact the Kolor Technical Support via our support forum.

On Mac and Windows

  • Rendering high FPS footages
    • If the FPS of your source videos are higher than 60fps, you will not be able to render the video with the FPS of your original video. You will get a memory leak which can make the application crash.
      Choose FPS: as preset option in the render window

  • Application crashes during startup on some Windows 10
    • We are not able to reproduce this issue on our own Windows 10 configurations. So, we cannot offer any workaround or solution yet.

  • Stitch and patch
    • If you have added a patch (a still image) you cannot reuse the stitching tool of AVP. If you want to stitch again a part of the timeline, you must re-optimize with APG (so you can’t use the range stitching for improving a part of a project)

On Mac (not yet corrected on v2.2.1)

  • The timeline cursor freezes
    • We are not able to reproduce this bug, however closing and re-opening AVP seems to be the trick. See the issue feedback on the forum over here
