WHAT FILE TYPES ARE SUPPORTED BY BRIDGE?
The file types that are compatible with Bridge are .jpg and .png files for images and any video files (eg .mp4 and .gif).

For images, the maximum file size is 12MB, and the dimension requirements are: minimum 320px, maximum 10,000px. For videos, the maximum file size is 100 MB and the minimum size is 320px. We have no length restrictions for the videos, but we recommend to keep it under 45 seconds.

I DON’T KNOW HOW TO PRODUCE A VIDEO!
Of course you do! We are certain that you have already filmed something with your smartphone. That’s all you need to start creating. That being said, if you’re looking to level up your skills, there are many resources and tutorials available online on how to edit and process videos, which can help you implement your idea. Check out some tutorials here.

SHOULD MY VIDEO HAVE SOUND?
Sound extends the experience of your AR artwork. If you are creating for an exhibition and are concerned that this might disturb other visitors, you can set it so it will only play over headphones. By clicking the “headphone” button, you can activate or deactivate the option to play the sound only over headphones. If your video has sound, this will be played and can be heard, provided that the user’s smartphone is not on mute.

CAN I MAKE MY VIDEO TRANSPARENT ON BRIDGE?
Videos can be made transparent by selecting a color to be eliminated, either by using the color-picker tool or by entering the color’s value. You can also adjust the threshold to set the transparency level.

WHY IS IT NOT OPTIMAL IF THE VIDEO IS LONGER THAN 45 SECONDS?
In order to view artworks, users must hold their devices upright and point the camera at the artwork. We have found that after 45 seconds, it becomes tiring and the focus shifts from viewing and enjoying the artwork to maintaining a steady hand. Therefore, we suggest making videos that have a length of under 45 seconds. There are no restrictions though, so you can make a video longer, just keep this in mind.
