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
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:
|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)
Try as far as possible to keep your interesting content outside of the overlapping areas, the results will be better.
For more information see Parallax zones
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.
We recommend to use an audio AND motion synchronization.
