Autopano Video - FAQ - Input, Output & Using the software 200

AVP & APG

As a reminder, you may need Autopano Giga to do some corrections (add control points to reduce/remove parallax issues, remove ghosts):

Input

Are there specific settings required for my cameras to shoot 360 videos?

There are some basic requirements: make sure that there is sufficient overlap between the videos (shoot in 4:3 format) and that they are all at the same frame rate, otherwise stitching will be impossible.

See here to set up your GoPro cameras.


Is there any example footage I can use to test Autopano Video?

Of course! You'll find some sample videos to download here.


Does Autopano Video support 4K stitching?

Yes, it's fully supported. The result can vary depending on your hardware.


Which video formats are supported in input?

See supported formats and limitations.


Can I input an already stitched 360 video ?

Autopano Video does not support ready-stitched 360° videos in input.


Does Autopano Video stitch Ricoh Theta 360 videos?

Autopano Video doesn't stitch Theta videos.
To stitch it you have to send it through the Ricoh Theta viewer software, it will stitch it automatically. However, you have no control over the horizon so if it wasn't shot straight there isn't much that can be done.



Output

How can I view 360° videos properly?

360° videos require a specific player to be played properly. Offline, on Desktop (Windows, OSX & Linux) you can use the GoPro VR app. If you want to host the videos online, you can use Youtube360 or Vimeo


Can I upload videos made with Autopano Video to Youtube360?

Youtube360 has an app that you must run your 360° video through before uploading, to be recognised as a 360° video.
Autopano Video will inject the required metadata when rendering your video automatically, just like the YouTube script, if Python 2.7 is installed on your computer, however if you edit the video you may have to add the meta data back.

See the YouTube help on 360° videos.


Can I upload videos made with Autopano Video to Facebook 360?

Just like Youtube360, Facebook requires the same meta-data for your videos to be recognised as a 360° video.
Autopano Video will inject the required metadata when rendering your video automatically, just like the YouTube script, if Python 2.7 is installed on your computer, however if you edit the video you may have to add the meta data back.

See the Facebook help page on 360° videos.



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".


Further hints :

  • Are you files located on a distant server? If so, copy them on your local system and try again.
  • Does you files/directory contain some special characters (space, accented character, ...)? If so, remove them and try again.


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 or external drive? If so, copy all the files on a local drive and test.


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/Mask ... => 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 (red circle on screenshot below) will result in no changes being applied.


  • 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 Mask and Stitch made in APG are going to be applied to AVP because those two tracks are currently in an editable state (blue). Changes related to Colors or the Horizon will be discarded since the current moment is not located to a blue state in those timelines (as shown below).

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

See saving changes in Autopano does not update in Autopano Video


Autopano Video crash when you save the project

If you own a Dell computer, uninstall Dell Backup and Recovery. In Autopano Video, unticked "Use system file browser" in the general settings tab. Re-launch Autopano 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 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 blend 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

Explanation
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)


Solution
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
