Autopano Video - Preferences - Panorama

Warning Changes to the Preference settings in the renderer will be applied by default to the entire new image group created.

The Render tab is in all respects identical to the one found in the general settings or in the editing window. It is a default parameter for the rendering options that will also be visible and modifiable at the time of the final rendering.
If you make a mistake, you can use the "Restore defaults" button.

Render tab

This lets you adjust the panorama’s export size in percentage of the maximum size.

The interpolator is used to project the pixels of the source image on the panorama. Its quality often depends on the sharpness of the panorama.

  • Nearest Neighbour: Reserved for testing, because of the numerous and very visible artifacts created. In return, this is the fastest.
  • Bilinear: This is a correct quality/speed ratio choice.
  • Bicubic: (default) Use it if you do not know. The difference with the bilinear is almost imperceptible to the naked eye but can be seen in the lines with strong contrasts. Its default use is recommended.
  • Bicubic sharper: This is the same thing as the bicubic but it is stronger (the fortification level corresponds to the same settings as in Photoshop when changing the size of an image).
  • Bicubic smoother: This is the same thing as the bicubic but it is softer (the softening level corresponds to the same settings as in Photoshop when changing the size of an image).
  • Spline36: This powerful method of interpolation is to be used when extreme or high post-rendering is necessary. The difference with the bicubic mode is not noticeable to the naked eye.
  • Spline64: Works in the same way as the Spline36, but stronger, slower and usually better (expirment to sample resutls).

Blending settings
The purpose of the blender is to combine the overlapping zones without it being noticeable, to obtain a perfect stiching of the panorama's images.
Autopano offers 4 optimization presets adapted to your needs without having to change them yourself.
These profiles correspond to the pre-configurations that can be seen in the “advanced settings”.

  • Simple: This is fast but it is possible that defects are seen where the areas overlap.
  • Anti-ghost: Conserve the image's strong characteristics (stops, lines, curves) when mixing while automatically removing objects that have moved.
  • Exposure Fusion: To be used if the panorama was created with a bracket shot. Keeps the best of different exposures.
  • HDR output: To be used by users who wish to create a .hdr format file in order to create post-production or special effects.
  • Custom: This is enabled when you manually change the parameters and they no longer correspond to a preset.

Advanced settings

  • Blending:
    • None: For each position, the algorithm uses the pixel with the greatest importance according to the required weight.
    • Linear: The rendered pixels are the result of a weighted average of input pixels.
    • Multi-band: Lets you mix the average value (color trend) of the images while maintaining their details.

  • Diamond: The pixels in the centre of the images are more important than the pixels on the edges of the images.

  • Fusion: enable/disable the tool.

  • HDR ghosts:
    • Avoid mixing the superimposed pixels that do not have the same information and that come from different levels (moving object on the same bracketed image).
    • At least 3 different information (layers) are needed to determine the information to exclude. It is advisable to get more for a greater reliability of matches (warning, a layer that is entirely over-exposed or under-exposed can not be used).

  • Cutting: Lets define the cutting choices of the blender according to the desired result (ghost removing or long focal preservation) thanks to the priority's definition slider:
    • Ghost: (default) all moving objects will be retained or removed according to their positions in the overlap areas. The anti-ghost himself makes this choice.
    • Long focal: Used to promote the details of the images of long focal length.
The left side of the slider bar enables the Ghosts removing at 100% and makes the Long focal preservation inactive.
The right side of the slider bar enables the Long focal preservation at 100% and makes the Ghosts removing inactive.
Move the slider bar allows to play on both settings (ghost removing or long focal preservation) at the same time, ie giving more priority to one of both settings leads to a lower priority for the other.
Consult the following page Understanding and using the rendering engine for more information.

Lets you choose the output format, encoding, compression quality and resolution.

Exported data
Lets you define how and what data needs to be exported:

  • Data:
    • Panorama: Lets you export the panorama.
    • Layers: Lets you export the image groups.
    • Images: Lets you export the images used to create the panorama.
  • Options:
    • Embed all outputs: Incorporates all the data in the same file.
    • Remove Alpha channel: Deletes the alpha channel of the exported files.


  • Folder: Lets you specify the file in which the image will be saved.
  • Filename: Default syntax of the file name. Click on the Autopano 250 icon help.png icon for a description of the symbols that make up the models (syntax) of the file name.

Rendering done notification
Lets you specify a sound that signals the end of the rendering.
