    Video Quality Playback Question

     

    I’m getting ready to start editing an HD project (my first one) in DVCPRO 100.  I’ve captured all of the video on 5 sata striped drives inside a Sonnet enclosure. I noticed when I play back a sequence on the time line at full quality (solid green mode) I get an error saying video output unable to maintain sync. I then switch back to daft quality and problem solved. It doesn’t matter which quality icon is selected when playing back through the deck with an HD monitor, the monitor output always looks good. I’m just wondering if something is wrong with my setup for HD editing or is this normal?

    Re: Video Quality Playback Question

    I found that my raster type under the Format tab was set to standard, when I changed it to DVCPro HD the HD video played in full green mode. I looked up standard raster type and found when the project is 1080 59.94 as mine is the standard raster size is 1920x1080, when set to DVCPro HD the raster size changes to 1280x1080. My question now is if I wanted to play video in full green mode using standard raster size what am I missing? Is it a matter of screen resolution not being set properly?

    Thanks

    What Avid is doing is correct - the DVCpro HD format is anamorphic.  In 60 Hz projects the true size encoded is 1280x1080, and in 50 Hz projects is 1440x1080.  Avid's full screen display though is still 1920x1080.

    If you want to work with square pixels you'll need to transcode to one of the DNxHD codecs.
