Recording Quality and Reliability
Zencastr records each participant's audio locally at 48 kHz WAV and video at up to 4K (Grow plan) or 1080p (Standard plan). Local recording is the key differentiator from Zoom-style recording — because audio is captured on the guest's device, a choppy internet connection causes conversation lag but does not degrade the actual recording file. Each participant gets a separate track, giving you full mixing control in post-production. The platform supports up to 12 participants with separate tracks for each. The reliability picture is mixed. Zencastr uses progressive upload technology that sends audio data to the cloud in real-time as a backup, which protects against browser crashes or disconnections. However, user reviews flag stability issues on longer sessions (30+ minutes), particularly on Mac with non-Chrome browsers. Safari support exists but is not as stable as Chrome. For mission-critical interviews, always use Chrome, keep sessions under 90 minutes when possible, and have a backup recording running on a separate device.
