V1.4 - Application Settings

Basics

This dialog will allow you to set all the software preferences as well as the default settings for many tools. You can open the dialog using one of the following depending on your operating system:

  • Icon-windows-16.png Edit: Settings
  • Icon-apple-16.png Autopano Pro: Settings

The dialog is divided into 5 tabs: General, Detection, Optimization, Editor, Render.

General

General setting tab
  • Temporary folder: Allows you to choose a folder path where Autopano Pro will write the temporary files it needs. If you have multiple physical drives on your computer then choose the one you purchased last as it is probably the fastest drive on your system and the one with the largest amount of free space. The choice you make here can be very important if you are stitching very large panoramas (even more if you use the PSD/PSB multi-layer format and/or using Smartblend as a blender). In the event your are running out of space you will see an error describing how much space you need to stitch a particular panorama, so you can change the temporary folder path accordingly. Please note: you need to restart Autopano Pro for changes to take effect.
  • Memory Used: The header is related to memory management for Autopano Pro. Please note: you need to restart Autopano Pro for changes to take effect.
    • Cache size (MB): Set the amount of RAM used by Autopano Pro to cache image information. There is no universal good setting, but keeping the value close to 15-20% of your total RAM should be sufficient. Keep in mind that, beyond a certain point, more cache will not speed up the Panorama editor or the rendering process. Those depend mainly on your CPU and hard drive speed.
    • During rendering: By changing our cell engine settings, you can reduce the memory usage. You should need to change the default setting only when rendering big panoramas (>100 pictures) on a machine with less memory (512MB RAM, for example). This flag has an effect on Autopano Pro only during rendering.
  • Language: Choose a language for the Autopano Pro interface. Currently (version 1.3) the supported languages are: Dutch, English, French, German, Italian, Polish, Russian, Spanish. Please note: you need to restart Autopano Pro for changes to take effect.
  • Number of CPUs: Autopano Pro was build from the ground up with multi threading in mind. It takes full advantage of dual and multi core CPUs, as well as multi processor configurations. At installation, Autopano Pro will detect the number of CPUs available in order to use the full computing power available on your system. This setting can be manually altered.


Detection

Detection settings tab

Detection settings determine the speed, quality and a few other aspects when it comes to scanning an image group looking for panoramas and stitching the images together. It is important to understand that the Detection Settings have two instances - Global, set from here, and Local, set for each image group, if need be. Whatever you set in this dialog will be the defaults for every newly created image group, you can then alter the settings locally on a per group basis using the Local Settings once the group is created.

  • Detection Quality - determines how much work will be put into finding matching areas and points in overlapping images. This setting is very CPU intensive and using High or Maximum can multiply the detection time from three to four times.
    • Standard: This is the default setting and, for most cases, is a good compromise between quality and detection speed.
    • High: Increases control point density and accuracy, but slows down the detection speed. Useful in cases with small overlap between images, bracketed photos, or other specific cases. Note: most experienced Autopano-ers set High as their default, as it usually gives better results without too much of a wait on a high-end computer.
    • Maximum: The most accurate, but also the slowest method. Used mainly for desperate cases. It can save the day, but prepare for a long wait. This method is also known to sometime produce an excess of control points that can actually ruin a good panorama, so use in extreme cases only.
  • Key Point / Image Pair: Set the number of control points per overlapping image pair. Keep in mind that too many control points will not lead to a better panorama. Anything above 100 is, in the generality of cases, useless. For the average user, 50 control points should be quite enough.
  • Force every picture to be in the same panorama: Self-explanatory. There are cases where you know a set of images belong in a single panorama, but Autopano Pro fails to detect a panorama at all, or leaves some of the images out. Checking this option will force Autopano Pro to always try and make a panorama of all images in an image group, no matter what. Note: if your workflow includes putting each image set in a separate folder prior to dropping them into Autopano Pro, you will want this option turned on by default.
  • Optimisation: By default, the two following options are checked and this setting should work fine most of the time. Turning those off will really speed up the detection of large panoramas (hundreds of files). The third option should be used in case of fisheye lenses.
    • Strong algorithm: Turn on/off the use of a stricter algorithm while optimizing after panorama detection.
    • Lens distortion: Turn on/off the lens distortion correction logic.
    • Advanced distortion: Check this option if you use fisheye lenses.
  • Project: You can modify the destination folder and the name syntax of the project files.
    • File name: Set a template for naming all detected panoramas. This will be the project file name if you decide to save it, and it will show in the Panoramas View, as a title for each panorama. Click the ? (question mark) button next to the text field to see the syntax used for the file name template.
      • %i / %I - short / long name for the first image in the panorama (short = filename; long = full path and filename)
      • %j / %J - short / long name for the last image in the panorama (short = filename; long = full path and filename)
      • %n - number of images used in the panorama
      • %g - auto incremental index
    • Directory: Set the folder where the project file will be saved when Auto save and close is checked
  • Automate: Autopano Pro is able to build great quantities of panoramas in a totally automated way. You can use the provided check boxes to choose what options will be enabled by default.
    • Auto crop: Crop the panorama to its usable pixels (i.e. non-black, containing image information). Same as the Crop tool in the Panorama Editor.
    • Auto color correction: Turn on color correction, as set in the Editor tab of the settings. Same as the Standard color correction switch in the Panorama Editor.
    • Auto render: Add the panorama to the Batch rendering interface and begin rendering as soon as the detection is completed.
    • Auto level: Adjust the level automatically.
    • Auto save and close: Save the project file in the source files' folder and close the panorama for later editing.



Optimization

Optimization settings tab

Optimization Settings determine image positioning, the quality of CP pairs, global RMS and the overall panorama quality. It is important to understand that the Optimization Settings have two instances - Global, set from here, and Local, set from the Control Points Editor. Whatever you set in this dialog will be applied to every newly created panorama, unless overridden by its local settings.

  • Optimisation: By default, these two options are checked and this setting should work fine most of the time. Turning those off will really speed up the detection of large panoramas (hundreds of files).
    • Strong algorithm: Turn on/off the use of a stricter algorithm while optimizing after panorama detection.
    • Lens distortion: Turn on/off the lens distortion correction logic.
  • Geometry analysis: Geometric analysis automatically looks for control points in all images. This option defines the behavior of the Add control points using geometric analysis button in the Control Points Editor. As this analysis relies on images already pre-positioned, Autopano Pro can concentrate on the seam areas between the images. Three modes are provided:
    • Find control points where none exist: Look for control points between overlapping images that have no Image Link created. Use this mode when there are some missing image links.
    • Find control points everywhere and merge with old CP: Look for control points in every image, then add the newly generated points to those already present. Use this mode when there are too few control points in the panorama overall.
    • Find control points everywhere and remove old CP: Look for control points in every image, then remove the current points and use only the new ones. Use this mode when the overall control point quality is weak.
  • Bad control points cleaner: This function is like a filter applied to all control points, leaving only the best ones. This option defines the behavior of the Clean bad control points button in the Control Points Editor. Two modes are provided:
    • Keep control points below this error (RMS): Remove all points that have a RMS above the selected value. Gives better quality, but with badly positioned images can remove most of (or all) control points.
    • Keep the N best control points: Leave an exact number of points per image pair, removing only the worst ones. Usually the best mode with hand-held panoramas or difficult cases.
  • Auto fine tuner: Allow you to trigger the following functions automatically:
    • Use geometry analysis
    • Use bad control point cleaner

Note: Use geometry analysis is launched before Use bad control point cleaner

  • CP detector quality: This options enables you to choose the quality of the control points detector. By defautlt, it is set on "standard", which is a good compomise between speed and detection quality. You can also set the number of control points to be detected.


Editor

Editor settings tab

The Editor Settings determine the preview quality in the Panorama Editor. This in no way affects the final panorama rendering - the render settings can be found in the Render Settings dialog. It is important to understand that the Editor Settings have two instances - Global, set from here, and Local, set for each panorama. Whatever you set in this dialog will be applied to every panorama you create, unless you override it with its local settings, from the Panorama Editor Edit: Settings menu.

  • Preview quality:
    • Size: Set the size of the panorama preview for the Panorama Editor in pixels. The default value is 1200 x 600 pixels. The preview refreshes after each parameter change in the Panorama Editor. You might want to experiment to see if bigger sizes (higher quality) will have better speed/quality ratio for you. 3200 x 1600 is the highest possible setting, but is equivalent to rendering a 3200 x 1600 panorama and can take some time. Interpolator and blender settings also affect the preview refresh speed.
    • Interpolation: Use to choose the interpolating algorithm - these are described in the Interpolation section of the Render Settings page.
    • Blending: Use to determine which blending mode will be used on seams. There are several blending modes but only some of them can be used for previews:
      • None: No blending applied, show the images stacked
      • Linear: Fast with reasonable quality blending
      • Multiband: Slower, but best possible quality. Note: For now, Smartblend is not available as a blending option for the Panorama Editor, only for final rendering.
  • Color Correction: This option defines the behavior of the Color Correction button in the Panorama Editor.
    • Initial type of anchor: Set a default type of anchor for any panorama with color correction turned on. When you turn on color correction, there will always be a single yellow anchor and the rest of the images will have the type of anchor you set here.


Render

Render Settings Tab

The Render settings determine the output file size, the quality, and the format of your panoramas. It is important to understand that the Render Settings have two instances - Global, set from here, and Local, set for each panorama. Whatever you set in this dialog will be the defaults for every newly generated panorama, unless you override the global settings with local settings at the end of the stitching process.

  • Size as a percent of the total image size (in the Local Settings, you can choose an exact size in pixels)
  • Interpolation and Blending algorithms
  • Output file format

A complete description of these options can be found in the Render Settings page. The following options are specific to the Global instance of Render Settings:

  • Output: Set the default location for the rendered panorama; you can also change this later, for each individual panorama
    • Folder: Set the folder where to save the output image.
    • Filename: Syntax of the filename (click on the "?" icon to learn about the signs)
  • Render done sound : Choose a custom sound to be played after all jobs in the Batch Rendering queue are done. You should provide an .WAV audio file.
