  • kona3 23.98 to dbeta is 3:13 to long

    Posted by Tracy Westgard on November 5, 2008 at 10:01 pm

    I have a 49 min program on a 23.98 timeline. When I edit to tape through a kona 3 the program ends 3:13 later than 49mins. Here are some particulars:

    23.98 timeline
    kona sdi primary 1080i29.97
    kona sdi secondary 525i29.97

    kona secondary to dbeta deck sdi
    audio in from aes/ebu 4 channels

    gen set to freerun
    no other things connected from nle(fcp) to dbeta

    I have spoke to aja support (awesome support team) and have gone though some of it and am just doing another output to see if it works, but does anyone have any other ideas and how to test them??

    Thanks,
    Tracy

    Are you going 29.97 drop or non drop? Have you accounted for this?

    Operator error –

    JG is correct.

    23.98 is always NON Drop,
    29.97 is usually drop frame(always in SD) in the US

    Yup…you have to plan for this. Find out what your drop frame deliverable is, then convert that into non-drop frame time…cut to that time.

    Use THIS timecode calculator. Link also includes link to what I had to do to figure out this timing mismatch:
