Main Interface

The main window is the sole interface for Autopano Video, enabling feed of completed work, importing source videos to final output.


The Autopano Video is divided into 4 areas:

  • A: Timeline
  • B: Video preview
  • C: Panorama preview
  • D: Video assembly preview



Timeline

The timeline is the navigation tool used for most features. Number values are defined in hours/minutes/seconds/milliseconds. Cursors are moved using the mouse.


  • The small white cursor shows the moment playing in the video previews and/or treatment. Or you can change the current moment by inputting directly a time in the "Spinbox" and press enter.
  • The 2 rectangular cursors show the start and end markers of the output sequence.
  • To jump to a specific moment, use the digital editor to the left of the timeline, enter the desired value and validate (Enter). The playing moment will be updated after every validation.
  • Clicking on the flags will use the position of the playing moment to define output sequence markers.

If the two checkboxes called "Seek on timeline update" are unchecked you can move along the timeline without moving the source or realtime preview videos. This can be useful on Macs where source seeking can be slow.

Video preview

This section of the interface lets you import videos and displays all source videos imported into Autopano Video.


Every video here contains its own playing interface. It is possible to play every video independently, adjust audio volume, etc. The actions possible in this window do not affect any of the rest of the process.

Importing videos can be done in several ways:

  • From the File/Import Video menu
  • Slide/Drop videos directly into the window

Icon attention.png Importing requires selection of all videos, so it is not possible to import videos one by one. If panoramas are loaded and do not concern the same videos, they will be automatically removed from the Panorama Preview area.

Stitching

Stitching creates reference panoramas corresponding to the playing moment defined in the timeline. 3 types of assembly are available:

  • Stitch as GoPro: (default) assembles videos according to the GoPro template and, more generally, most fisheye cameras.
  • Stitch as Pano: assembles playing videos from a panorama template created previously with other videos. The panorama used as template must contain the same number of videos as the running project.
  • Stitch as…: assembles videos according to defined personalized settings:


Focal (35 equiv) Shows the focal length equivalent to a 35mm lens.

Lens type Defines the type of lens used: Standard or Fisheye.


Launching an assembly using one of these 3 options will:

  • Sample one image per video (“frameNumber-face#.mp4.tif”) depending on the defined running moment
  • Create the corresponding panorama (“frameNumber-face0.mp4.pano”)

Note: these files are stored in the same folder as source video files.

Once the extraction is finished, the panorama is displayed in the Panorama Preview area.


Synchronization

  • Sound based synchronization
    • The Video column defines all video feeds of the running project.
    • The Start column defines calculated time difference to be applied to each video in order to synchronize audio signals.
    • Reset: sets synchronization values of all video feeds to zero.
    • Cancel: cancels the calculation if required.
    • OK: validates the synchronization and adjusts video feeds depending on the calculation made.

A Warning message appears if the differences calculate seem incoherent (depending on certain redundant information). In this case, the synchronization may be correct but it is still recommended to launch another synchronization to another moment in the sequence.

  • Maximum search range: defines the maximum time range used for synchronization.
  • Use audio to synchronize video: Sound based synchronization automatically detects time differences in the videos to associate audio signals to the running moment defined in the timeline.

Once the calculation is finished, time differences between audio signals of each video will be used to set the video start time.

Manually adjusts time differences using the Video Synchronization window. In the Start Time column, use the arrows (on the right) to reduce/increase time values. It is also possible to enter number values directly for more precision.

Note: After validating, synchronization is recorded for source video previews, for the creation of reference panoramas and for the video assembly preview.

Panorama preview

This area of the interface imports a project file (.pano) and displays reference panoramas created from an assembly (“Stich as” option). Each thumbnail contains a preview of the related panorama, the panorama name, its image format and its size in pixels. Selecting a panorama displays it in the video assembly preview.


  • Edit: opens the panorama in Autopano (Pro or Giga) for editing. Double-clicking on the preview (thumbnail) also opens the panorama in Autopano (Pro or Giga).
  • Remove: removes the selected panorama.

Importing projects can be done in several ways:

  • From the File/Import Panorama menu
  • Slide/Drop a .pano file directly into the window

If the videos associated to the imported project are not the running videos displayed in the interface, they will be automatically replaced.

Video assembly preview

The video assembly preview shows the result of the assembly made previously in Autopano (Pro or Giga) and to start playing it. Viewing does not allow 360° navigation and uses the projection defined in Autopano (Pro or Giga).


Output

  • Output: this option exports the final 360° video. Several encoding options are available:

Encoding rules

  • Preset: selects the encoding profile.
    • Best of H.264: automatically selects the most appropriate profile from basic H.264 profiles (Baseline, Main or High) depending on the size of the final video.
    • Best of BD H.264: automatically selects the most appropriate profile from basic BD H.264 (Low res. or High res.) depending on the size of the final video.
    • H.264 Baseline: appropriate for final videos with a maximum size of 320x240 pixels.
    • H.264 Main: appropriate for final videos with a maximum size of 704x576 pixels.
    • H.264 High: appropriate for final videos with a maximum size of 1920x1080 pixels.
    • BD H.264 Low resolution: corresponds to standard DVD quality (720x576 pixels).
    • BD H.264 High resolution: corresponds to BluRay quality (1920x1080 pixels).
  • Standard: selects video standard (PAL or NTSC).
    • As original video: keeps the standard of the source videos.
    • As preset: forces the Standard setting defined in Settings, Preset tab.
  • FPS:
    • As original video: keeps the fps value of the source videos.
    • As preset: forces the fps value defined in Settings, Preset tab.
  • Aspect ratio: defines resizing rules of video (frames).
    • Keep in display info: (by default) the aspect ratio in pixels is not necessarily respected, but the information is kept in the video feed to all correct display. Some video players do not support this information and may display poorly.
    • Keep in pixels size: the final video is automatically resized to respect assembly proportions.
    • Do not keep: uses the maximum size available without keeping assembly proportions.

Output

  • MP4: exports video in mp4 format.
  • Frames: exports video in frame-by-frame sequence format. The image format and the size in pixels correspond to settings defined in the reference panorama (Autopano Pro or Giga).
  • Audio source: selects the audio feed of one of the source videos from the scrolling list.
  • Restore default values: restores the default setting of the application
  • Apply: validates the modifications made to the settings without launching output.
  • Cancel: cancels changes and closes the output settings window.
  • Add to batch: adds the selected project to the list of batch jobs.
  • OK: launches the final output of the 360° video.

Batch output

Batch output options makes it possible to not output the videos directly and to add them to a list of projects to output in order to deal with them one by one, to avoid overloading the computer with work.

  • Run batch jobs: launches the output of projects added to the list of batch jobs.
