The app is exclusively available to our education partners who participate in the Pixotope Education Program and is not available for public download. If you are interested in testing Pixotope Pocket please contact your sales representative.
The app is currently available on iPhones only. We recommend X models and above, with iOS 16 and later.
For usage questions, please checkout the Pixotope community, as we currently do not offer active support.
Pixotope pocket is a mobile app that uses your iPhone’s camera and ARKit to send tracking data and a live video feed into Pixotope Director via SRT connection.
How to use
Note that your phone and Director machine need to be on the same local network
Please contact your sales representative for a Pixotope Pocket download link

The value will depend on the RTT of your connection.
RTT (Round-Trip-Time) is the time it takes for a packet to travel from source to destination and back, and it is measured using the ping command on the destination IP (Director machine's IP).
SRT latencyis a buffer that allows the destination to ask for missing packets to the source, for retransmission. Hence, this buffer must be larger than the measured RTT value.
The default value is 120 ms, which is typically suitable for local networks. Increase the value if you experience connection issues.
Set the same value on both ends of the connection. If there is a mismatch, the highest value prevails.
Increasing SRT latency increases end-to-end latency. Decrease this value to optimize latency, but ensure that the connection remains stable.
Choose a password with a length between 10 and 79 characters.
Configure the same password both in Pocket and Director
Video must be compressed (encoded) in real-time to send it over the network using the SRT protocol. Compression can impact latency and video quality.
Adjust compression settings to optimize connection stability, video quality, and latency.
Bitratebased on available network bandwidth and WiFi capacity.
If you experience video streaming issues, decrease the bitrate to improve stability while maintaining good video quality. Lower
Bitratevalues may affect video quality.
For a given
Different codecs impact video quality, latency, and phone performance
MPEG4should provide similar video quality results
H264uses less CPU hence it uses less battery and heats up the phone less
HEVCprovides better quality at low bitrates, at the cost of higher CPU usage
MPEG4provides lower latency
Codec, the value of
GOP Sizewill impact the video quality and latency
Lower values will result in lower latency
Higher values will result in better video quality and low bitrates
Measure RTT and configure the value in 3 * RTT (milliseconds)
In local network, use the default value (120 ms)
As high as possible without exceeding your network/connection capacity
Start with 20-50 Mbps and only decrease if you see instabilities in the video on your composite output
H264and, if bitrate must be pushed down to a very low value (15 Mbps or lower), switch to
MPEG4if you want to cut latency down to the minimum
Use default value (15 frames), decrease to optimize latency if needed
