  • captured Kona clips come in at 0.9:1 non-square

    Posted by Frank Ruggiero on April 27, 2005 at 3:32 pm

    Hi. I am new to the Kona 2 board. I have noticed that when I capture a Kona clip and use it in After Effects, its aspect ratio sets at 720*486 0.9:1 non-square, as opposed to the After Effects preset of 720*486 0.9 non-square. Does anyone know what that extra ‘:1″ means? If I put the Kona clip into a 0.9 comp, I see that it is slightly larger. Would there be any field issues if I shrink to fit, or should I have my comp set at 0.9:1 or should I just let the clip be slightly larger in the composition?

    I apologize if this is unclear.

    Any info is greatly appreciated. Thanks a lot.

    Frank R.

    I noticed the same thing, and when I rendered out in AE and re-imported the graphic, it did not match the source footage from which it came on the hz scale. This is the first time I have seen this since I’ve been using K2 this year. Can’t say whether this is a QT, AJA or something else issue.

    For those who aren’t familiar with this bug, when you select a clip in AE it shows: 720 x 486, non-square (0.91:1). It should show 720 x 486, D1/DV NTSC (0.9).

    My workaround has been to interpret the footage in AE (cmd + F) as 720 x 486, D1/DV NTSC (0.9) and everything is fine. Also, make sure that your sequences are also the same spec, especially if you drag/drop clips into the seq icon to create a sequence based on the clip specs.

    I checked all of my digitizing specs and cannot account for why this happens. Anybody?

    thank you steve.

    that seems like the most logical way around this problem. I am trying to confirm the issue with AJA to see if they have info on it. Ill post any results I can get from them.
