Creating Experiences

Do you have question about how to work with the Viond Builder? Here you might find the right answers.
I cannot open the Builder because it says it comes from an "unidentified developer". What can I do?
If this message appears, open the System Preferences, go to "Security & Privacy", then click on "Open anyway". The message appears on Mac because the Viond Builder is not yet available in the App Store and therefore, not an identified developer. 

How should videos be formatted?

For the Builder

Not all devices can play higher resolutions and higher bitrates. So, for preview purposes, Builder requires a full HD 1920x1080 maximal resolution and we recommend a bitrate of about 2Mbps. If you have a high performance device (e.g. iPhone, Galaxy S9, Pixel2), you can play 4K videos, so use a 4096x2048 resolution in the high resolution media path. In that case we recommend a 12Mbps bitrate. That way, you can preview your draft in the publishing section with a higher resolution. If you think your device is 4K capable but the draft preview shows only fullHD, let us know:

When publishing in an App

If you decided to publish in a Viond App, you must use maximum fullHD 1920x1080 resolution for the media path and 4K 4096x2048 for the high quality media path. We recommend 6mbps for fullHD and 12mbps for 4K. We will transcode it to support dynamic bitrate adaption and the different devices' resolutions.

How should images be formatted?
Supported image formats are PNG and JPG. For 360 images, we recommend using JPG as they are lighter, and the resolutions must be 1920x960 for the default media path and 4096x2048 in for the high resolution media path. Smaller 360 images can also be used, but we recommend the mentioned sizes to deliver the best quality the devices can handle.

For interactive elements, you can use PNG so the alpha channel results in transparency.
How should audio be formatted?

The supported audio format is MP3 stereo. We recommend using 256Kbps, but 128Kbps is also OK. 

We also support the TBE audio format. Get creative and make the most out of VR audio through spatial audio support.

How can I preview my experience?

For the local preview of your newly built experience, you need two things: 

a) The Viond mobile app

To download the Viond app, go to our product page, where you can find the links to the apps stores. 

b) You need to be in the same Wifi as your desktop machine. 

For the local preview, you need to connect your PC/Mac with the same network as the Viond mobile App. But you can also use the “Preview Draft” feature in the Slot Management section to preview from any location with internet. 

If you get the message "Could not start preview. Network discovery failed.", start by checking that Builder and device are on the same WiFi network. If not, stop sharing in the Builder and close the App. Then connect both devices to the same network. Start the Preview Mode again in the Builder and the re-start the App.

If the network is really busy, it can happen that the App isn't able to find the Builder. Restart the application to make another attempt. If it still does not work after several attempts and you are sure that the devices are on the same network, please contact

I would like to remove the Viond watermarks in my experience. What should I do?
Viond offers different licenses to publish your experience to multiple devices at the same time through our app. If you want to get rid of the watermarks, please have a look at our pricing structure or get in touch with us:
My preview download started but got stuck around the end. What should I do?

Newer versions of the App and Builder don’t have this bug anymore, but your device might have old data which causes the conflict. To solve it, do the following:

Go to Settings -> Apps -> Viond -> Storage -> Clear Data and confirm with “Delete”. This will erase all downloaded data and should resolve the preview issue.

To get the latest version of our apps, visit our product page and follow the links to the app stores or download the latest version of the Builder. 

How long does it take until my (published) experience is available in the Viond Player App?

We strive to review your experience in a maximum of 2 working days. If you stick to our guidelines, your experience will be live right after the review.

How can I share my experiences, e.g. on my Website, YouTube or Facebook?

With our new Viond Web VR Player, it is possible to embed an experience to any of your websites. Just open the Builder and go to the Publishing section, select your slot and the embed code will be automatically generated for you. You can use this code and past it in the source code of your website. If you don't know how to do that, please ask your web developer. 

You can also share interactive VR experiences using the Share Link, which is also generated within the publishing section of the Viond Builder. Users that installed the Viond app and open the link will be taken directly to your content. Putting an experience inside a YouTube Video or post the experience directly in Facebook is currently not possible, as YouTube and Facebook don't support these experiences.

I want to test Viond without any strings attached. Is that possibe?

Good thing you're asking! We do offer a free trial, which gives you the opportunity to create and publish experiences to the Viond app for one month - completely free! Visit our free-trial page to start your VR journey now!

You do not have to provide a payment method and the license will not automatically upgrade to a paid plan.
