Image Noise in SnapCall Uploads: Causes and Solutions

Issue: Image noise appears as speckles or grain in uploaded videos and images on SnapCall

Cause: Unstable network connections during upload can introduce noise into the media.


Unlike video calls where data streams in real-time, SnapCall uploads media files. Network instability during this process disrupts the data transmission, causing image noise. Three main factors contribute to this:

  • Jitter: Data packets containing image information arrive out of order. This disrupts the image reconstruction, leading to distorted or glitchy visuals.

  • Latency: Delays in sending data packets slow down the upload. This can cause dropped frames (missing image data) and incomplete images with a grainy appearance.

  • Packet Loss: Some data packets containing image information fail to reach their destination. This results in missing pieces of the image, manifesting as a grainy effect.


Ensure a reliable internet connection for smooth uploads and minimize image noise. Here's what you can do:

  • Network Bandwidth: Upgrade your internet plan, especially if you frequently upload large media files. Higher bandwidth provides a smoother data transfer path.

  • Wired Connection: Whenever possible, connect your device directly to the router using an ethernet cable. Wi-Fi connections are more susceptible to interference and instability.

  • Network Congestion: Minimize the number of devices using your Wi-Fi simultaneously. Avoid large downloads or uploads while uploading media on SnapCall. This reduces competition for bandwidth.

Additional Resources:

By following these recommendations, you can achieve a stable upload process and eliminate image noise from your SnapCall uploads, ensuring high-quality media for all participants.
