Hello team,

My customer is reviewing 949 and 940.

Hi Harry,

Are you specifically about the synchronization between the video and audio? There will not be any skew more than a frame for the video and audio data. Let me know if this answers the customers question.

Regards,

Jack

Customer just concern synchronization between video and audio.

So it would be less than 16.67ms in case of 60Hz. right??
