Autopano Video - Checklist before your record


This is a short checklist you can take with you if needed.
This is detailed on the 1 - Capture paragraph on the home page


Camera settings (HERO 3+ & HERO 4)

  • 2,7K 4:3 --> renders a 8K video file
  • 1440p (highly recommended) --> renders a 5.5K video file
  • 960p --> renders a 4K video file


If you are using a six or a seven camera holder you must use only the 4:3 modes of the GoPro and make sure
each GoPro is set with an identical framerate and resolution


Then you have to select the appropriate framerate. As we need to resynchronize the videos in post production you have to use a high framerate, but not to high to keep details in each image. Are the recommended modes:

  • Most versatile mode: 1440p @60fps
  • Static looking for very hi-res output: 2,7k 4:3 @30fps
  • To do slow-motion in post production: 960p @120fps

For advanced settings (WB, color and sharpening, ISO limit, exposure, …) See GoPro settings depending on the workflow


Usable modes

You have to make sure that you have enough overlap between all your cameras, if you don't you will not be able to stitch your videos.
Here are the required settings for GoPro based RIGS:
RIG Usable modes
360Heros H3Pro6 2.7K 4:3/1440p/960p
360Heros H3Pro6N 2.7K 4:3/1440p/960p
360Heros H3Pro7N 2.7K 4:3/1440p/960p
360Heros H3Pro7HD 4K/2.7K (recommended)

2.7K 4:3/1440p/1080p (wide mode) /960p (usable but not optimized)

Freedom360 2.7K 4:3/1440p/960p


Try as far as possible to keep your interesting content outside of the overlapping areas, the results will be better.

Synchronization

The video stitching is based on the stitching of images taken at a precise moment in the different videos. For this stitching to look as best as possible, we have to make sure that the entry source flow is synchronised.
The stitching allows you to define the relative positions of the cameras. If the flows aren't synchronised, it's the equivalent of relative motion of the cameras themselves (if one camera starts before another, the relative position isn't stable).
Ideally, it would be best if your equipment could assure this synchronicity but that is not always possible, which is why Autopano Video gives you the necessary tools to do so.

  • Sound: If your video and audio track are perfectly synchronized (very rare) this method provides a millisecond accurate synchronization.

Clap your hands twice. To be effective, the sound has to be clear, audible and identifiable (you can also speal at the beginning of the recording)

  • Motion: Can be very easily used in most cases and very reliable: frame accurate.

Turn around the RIG as shown below
Rotation for sync. H3PRO6 Rotation for sync.

We recommend to use an audio AND motion synchronization.
