Changelog for Autopano Video 2.5 Alpha 3

Main changes

This new alpha 3 release comes with some cool new features and some bugfixes done after feedbacks from users.

What's new ?

  • Alpha channel is now rendered properly for CineForm and ProRes. This allows to export individually each camera with the color correction, enabling more post production possible. See online documentation.
  • GoPro Omni Importer : the chaptered videos (many files on SD cards for a single long shot) are merged by the Importer. So the displayed preview corresponds to the single original captured footage.

Changelog for Autopano Video 2.5 Alpha 2

Main changes

We're quickly releasing this alpha to fix one main issue. After computing RMS curves, all others actions would cause crashes. We are already working on other issues but this one was often encountered and wouldn't allow users to test other features.

Fixes since alpha 1:

Crash at computeRMS
Exception error on motion compute
Crash after ComputeRMS
Render in MP4 has a different FPS from source videos
Crash at stabilization computation
Horizon Straightening
Changelog for Autopano Video 2.5 Alpha 1

Main changes

This release introduces a new cycle in Autopano Video software. This version is the first alpha version for the new 2.5 branch. It comes with some nice improvements. The following paragraphs will detail the changes.

GoPro Omni Importer

At NAB 2016, we announced a new 6 GoPro synchronized rig called Omni. This rig solves many pain points you have by using unsynchronized rigs, like syncing, data management, etc. You can learn more about GoPro Omni by just following this url: GoPro Omni Rig.

Alongside with GoPro Omni, we created a standalone application called Omni Importer, included with Autopano Video Pro, that is here to help you to manage the camera content in a simple and efficient way. This made the rig offloading as well as the stitching of your shots really easy to do.

With the Omni importer, our idea of ideal workflow is the following:

  • Plug the SD cards to the usb hub
    Launch the Omni importer. It will scan for SD cards and if Omni content is found on them, it will automatically show all content in a nice interface.
  • For each content, decide what you want to do with them
    Each scene, can be previewed directly from the SD cards through a quick stitch (it isn't a high quality stitch as it is based on video thumbnails and not low quality videos (.THM and .LRV), but it is super fast and reflects well the captured content). When reviewing a video, you can select a range in the content in which you are interested in. Note: you can edit the title of each video in the video's header.
  • Import, stitch steps
    Once you have reviewed your content (removing those you are not interesting in and adjusting the range for the others), you can import, stitch and compute the selection. This is when the real calculation happens. You will find several options at the bottom of the window, so you can apply stabilization, color correction and choose if you want render or just import files. In any case, even if you don't select any options, the importing and stitching processes will happen. Import means SD card content will be copied locally and reorganized by the title name you have edited in the content title. Stitching is when a stitch is created for this content. That stitch is based on a pre-calibrated stitch so it cannot fail even in case of full black videos. At the end of the stitch, you'll have a .kava project file.
  • Compute steps
    If you have selected some computation to be done while importing, after the stitch, these computation will be done on the .kava project file. On the selected range, we can compute stabilization track, the color correction tracks or even do a rendering of the quality you have selected. This is really a good workflow to do so, as at the end of the import process, you have a .kava project file that is ready to be fine-tunned in AVP and that already contains all the time consuming computations done.

The idea of Omni importer was really to ease the work at capture time. Just remove the SD cards from omni, put a new set of SD cards in it to continue capturing. While continuing the shot, an other member of the team can review on stage what has been captured. If needed a stitch can be done in a few clicks too. But at any time, as you have access to the project file, you can be also really accurate thanks to Autopano Video features. The Omni importer can be used in a fast workflow or a powerful workflow.

Some technical notes:

  • File naming / metadata scheme
    One of the complicated tasks when using multiple camera rigs, is to associate SD cards back to cameras. This is a delicate and time consuming task. With Omni, the rig itself solves that problem by having a file naming scheme that allows you to know from which camera the content comes from. We also added dedicated metadata within the mp4 itself to do the same. The Omni importer makes uses of this metadata to associate each camera with their scene.
  • GoPro Omni Importer Settings
    The Omni Importer shares the same settings as AVP. So if you decide to do CPU rendering in AVP, it will do the same in Omni Importer. We decided for such a design so you don't need to change general settings in two places, only one place which is in AVP settings.
  • Smart horizon on static scenes
    For static scenes taken from a pole, your horizon is directly straightened in the preview of the Omni Importer

Autopano Video new features

While working on the Omni importer, we also added several cool new features on Autopano Video. Here's a detailed list of the new features.

  • Undo / Redo / History framework
    Yes, that standard part of a good software wasn't available before. We took it really seriously and now, you can do a CTRL+Z in AVP. You also have access to a history window that allows you to rollback several operations.
  • Apple ProRes support
    By popular demand, we added official support to Apple ProRes in input and output of AVP. This feature allows some strong workflows if you are going to edit the footage afterward in final cut for example.
  • New Stereo Rendering Options (AVP only)
    Most of the time, default 3D-stereo settings (known as interoccular and convergence) are the most suitable. But in some very specific setups, you may have to face compromi deviates from standard values. For that purpose, we allow you to alter (when possible) those two key values. See the documentation for more details.
  • MP4 file merger
    One of the features that AVP 2.3 users really loved, is the fact that gopro importer wizard merges MP4 files together automatically when the content was from the same long duration shot (The GoPro camera divides long shots into several MP4 files). Our customers told us that they were interested in having the merge tool only. It is now available as a single action in the AVP menu.
  • Clever interface to retrieve missing videos
    Added an interface to relink videos that are missing when opening a kava file.
  • Improved batch renderer
    Re-organize your batches, drag'n'drop you kava files that are ready to render directly in the batch render of AVP to add batches.
  • Small UI updates
    Moved some menu, added short cuts, and tool tips with shortcuts in them
  • Rolling shutter effect reduction for Omni videos
    Autopano Video detects shots captured by GoPro Omni rigs and applies corrections for rolling shutter, allowing to reduce the related artefacts.

Adobe Premiere Pro Plugins

This is also new for this 2.5 series. Customers were really interested in having more tools to improve the 360 workflow after stitching was finished. And this is why we got into NLE plugins development specifically for VR. This version introduces 2 Adobe Premiere Plugins: (Compatible from Premiere Pro CC 2015 onwards, these two plugins are available in the Video Effects menu under GoPro VR folder)

  • GoPro VR Horizon
    This plugin assumes that the input video is a 360 spherical video and the output after processing is a 360 video as well. It lets you straighten the horizon according to 3 sliders representing the yaw, pitch and roll axes. You may even do this job more easily by using the mouse directly on the composition window. You may also place some keyframes to create transitions between spherical point of views. An optional "Smooth transition" checkbox helps you smooth complex transitions.
  • GoPro VR Reframe
  • This second plugin assumes that the input video is 360 spherical video and the output a standard video. By moving the FOV slider and the 3 axes yaw, pitch and roll (mouse is available as well) you can change the field of view and the point of view of the video and obtain a projection going from little planet to a classical planar projection. And just like GoPro VR Horizon, you can use keyframes and the "Smooth transition" checkbox to create your storytelling.

Note: A 360 video viewer plugin for Premiere Pro is available when downloading KolorEyes desktop and lets you see direct result of your video editing in Premiere Pro.
