Slow rolling image issue when monitoring RED camera output on Camwave

DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.
What the thread found
- The Camwave monitor does not accept straight 24fps input; compatible formats include 1080p/23.98, 1080i/59.94, 1080i/50, 1080p/29.97, 720p/59.94, and 720p/50 for HD-SDI, plus 525i/59.94 and 625i/50 for SD-SDI.
- When experiencing rolling images while shooting at 24fps, switching the monitor output format to 25fps while continuing to record at 24fps can eliminate the rolling effect.
- A software upgrade was available to resolve this issue.
- The problem has occurred with multiple RED camera models including Scarlet and Epic.
- Rolling image issues may relate to the RED camera's firmware build version or specific SDI output configurations.
Depends on
- The exact software upgrade version and timing are not specified.
- The suggested resolution of switching monitor output to 25fps worked in some cases but not others; inconsistent results suggest the root cause may be multifactorial.
- Observations come from different camera models and setups, making it unclear whether the issue is specific to certain firmware versions or configurations.
- The frame rate mismatch theory between camera and monitor is mentioned but not definitively confirmed.
