Hi , I am a newbie in television studio switcher (just ordered one) , my question is to understand how re-sync of camera signals in bmd television studio work ? and if i use consumer cameras with Hdmi , which have different latency in HDMI output , will the switcher be able to re-sync video signals correctly using this feature.

Thank you

Yes, there is atomatic frame sync on all inputs.
All sourc inputs must however be the same resolution and frame rate unless you have the TVS 4k Pro.

This is not what the frame sync means. The framesync will allow you to switch between cameras that are not genlocked, all it does is buffer the frames so that the first pixel timing on each input is time aligned with the first pixel timing on the internal clock. It does not have the ability to delay feeds to compensate for latency. Depending on how far off the frames come in (this is pixel wise only) the unit can induce a whole frame more latency on input to time align the incoming signal with the internal clock. This can make the discrepancy between cameras worse, but without genlock this is a bit random.

Thank you all for your input , really helpful , i received the switcher today, i guess i will have to test with my cameras to see how accurate the compansation is , and if it is usable for my case. Of course currently i dont have cameras with genlock feature as they are a bit more expensive , thats why i asked.
