    Dropped Frames on Digital Cut

    Working on a new Nitris DX, smoking fast, all the bells and whistles MAC tower.  Im trying to do a SDI layback to tape on a DVW-A500 but I keep getting dropped frames.  The SD-SDI light on the front of the box is blinking green and orange, sync light is solid green.  Any help would be great as I am up against a deadline.  Are there specific settings I need to enable for SDI out?  I have tried restarting everything except the G-Raid.

    Make sure the Video Effect Safe mode is switched on in Digital Cut and render all your effects. If this is still a problem do a Render All fx inlc real time ones.

    Thanks for the reply.  Safe mode is on and I have rendered EVERYTHING.  I even tried doing a Video Mixdown.  Could it be my graphics card needs re-ceeding?

    Re: Dropped Frames on Digital Cut

    Is your material on a FW Graid?

    How busy is the audio? Can you cut sections of the seq to tape with no frames drop or is it persistently one area?

    i suspect it's not the card - more likely the drive getting choked on output

    Material is 1:1 on a G-SPEEDfc, The audio is mixed down by an audio facility to a two channel wave.  The dropped frames are entirely random.  I think its the drive also, but you would think something brand new would not have problems.  I have just been picking up edit points when it stops, not efficient, but it will get the job done.

    If that's the 6 drive G-Speed, I've found that they can have problems, for some reason. I've even had trouble playing DNX on a digital cut. (??) I'm thinking it's some sort of buffering in the controller or something like that. I can digital cut off of 8 drive raids, but that little 6, doesn't always work.

     

    You can speed test it, and it's crazy fast, and FCP will play all day long but a Digital Cut is a different deal. Test and see. (Try to get a 16 drive box and run one of the 8 drive sides to test.)

    Don't trust the internet...

    Hi,

      If you are using external referance make sure the reference loop on the Nitris DX is properly terminated with 75 Ohms terminator or try to use internal referance.

     

    Thanks ,
