Content FAQS

Can I use 4K 360 videos?#

Yes, but with a few limitations.

4K (3840x2160) videos can be used in the experiences meant for viewing on a PC or Oculus Go. These are currently incompatible with mobile phones.

We recommend you downsize your 360 videos to 2K (2048x1024) to make your content compatible everywhere, unless meant exclusively for PC / Oculus Go.

How to clean up the tripod?#

Tripods, Monopods or Drones often leave ghost marks at the bottom of your 360 footage.

Removing tripods can often be tedious, and the simplest way is probably just to cover it up!

Use your logo, or any other image and add it at the bottom in the editor to make your problem disappear. This saves additional work, and is a great way to push in some branding.

However, if you really want to clean up the tripod from your footage completely, here's how you could do that.

Here is a quick tutorial on how to remove the tripod using Adobe Photoshop, Premiere Pro or After Effects:

Mettle Sky Box is now a part of the Adobe Suite (>Adobe CC 2018). You can use the same features from the tutorial using the now inbuilt features of After Effects, like this:

Use the "Immersive Video>VR Converter" effect in place of "Mettle Skybox Converter"

Use "Window>VR Comp Editor" instead of "Skybox Composer"

Why do my panoramic photos look less than stellar?#

The GMetri platform does not downgrade any images uploaded in any way. If there is any quality variance, it may be due to the camera settings or the export/compression settings. Here are a few things you can try to make sure you get the best quality out of your camera: First, try to zoom out using the editor's zooming feature. If that didn't work,

  • Ensure your Camera Firmware is up to date 
  • Your Fusion Studio app also needs to be updated
  • Clean the camera lens before taking pictures to avoid smudges
  • While exporting from Fusion Studio, you can also adjust the colour settings to make the image look better
  • If you are compressing your images, there will be a drop in quality. Find the best compression to quality ratio that works for you by trying them out for yourself. GMetri Suggested Compression for JPEG - squoosh and for PNG - tinypng

How to set up the camera view at the beginning of the scene?#

We can set up the camera view at the beginning of each scene, by accessing the scene properties. You can do this by selecting the scene in the Structure tab and then open up the Properties tab. The scene has the following properties:

  • Scene Yaw Correction - Which will set the direction the scene will start with, in yaw (horizontal direction)
  • Scene Pitch Correction - Which will set the direction the scene will start with, in pitch (vertical direction)
  • Scene Reset Rotation - Which will reset the scene rotation to the Scene Yaw and Pitch Correction values every time the scene is changed to this current scene
  • Scene Gyro Lock - Which will lock the gyroscope of your device, ensuring your content remains on screen no matter how you turn your mobile device

For example, if you want the scene to start every time looking 70° to the right, set Scene Yaw Correction to 70° (or -70° for turning left) and switch on Scene Reset Rotation.
