14 years agoHi,
You probably do not want to use the "Support for LOCKED frame rate conversion". It is an advanced feature for users that use genlock and can synchronize the CVO output clock to the CVI input clock. Clocks are not perfect. It is very likely that you are getting a flickering because the ratio between your input frame rate and your output frame rate is not exactly 60/50. At some point the input will have produced more data than expected or the output will be starved and a frame buffer doing locked rate conversion will not compensate for that. Enabling "Frame Dropping" and "Frame Repeating" is usually enough to get a working triple buffer. The IP then decides on its own when to drop and repeat frames based on the input rate and the back pressure applied at its output.
