problem displaying XDCam 1080i50 files

Posted by Carsten Orlt on February 10, 2012 at 7:32 am

I have problems displaying some xdcam files I received from a client.
They are 1080i50 35 mbit. Picture has rows of green, purple and white dots. You can make out the image but it has those faults.
The clip plays fine in Quicktime player (OSX 10.7.3)

I have also some xdcam 1080p25 footage from the same batch I received which is fine?

Any idea why this could happen?

Thank you
Carsten

When you say they play in QuickTime Player, do you mean 7 or X? Are you using Calibrated?

From the sound of it, I believe you may be seeing an issue with the AppleHDVCodec that Greg at Calibrated did some analysis on. It seems the current version of this codec gives green and pink patterns when playing XDCAM EX and HDV footage in some applications, whereas if you revert to AppleHDVCodec 1.6 then it works.

I’m on QT player X, OSX 10.7.2.
How could I revert back to v1.6 of the HDV codec?
Cheers

Also just tried my other partition with has OSX 10.7.2 and FCP Studio 3 (full installation of all apps) on it and in this combo the clip plays fine in CatDV and QT player X

Hi Carsten,

Correct – from the tests we’ve done here – where the large viewer window in CatDV shows the green/pink plaid over the video:

1) Only XDCAM EX, XDCAM HD 35 Mb or HDV Interlaced video is affected (these are 420 encoded)

2.) XDCAM HD 50 Mb (progressive or interlaced) is 422 encoded and is not affected .

3.) XDCAM EX, XDCAM HD 35 Mb or HDV Progressive video is not affected.

4.) The issue is only present when either the 2.0 or greater Apple XDCAM Codec is used. If the v1.6 Apple XDCAM Codec is used then everything is fine.

Hope that helps!

Cheers,
Greg

It actually seems to be down to whether the movie is being shown bigger than 960×540, rather than whether you use the separate media dialog window or not. We’re still investigating whether this a problem in CatDV or a QuickTime codec bug.

Thanks guys, but can’t confirm that it only happens with a certain size. On my machine the problem appears regardless what size the QT window or wether its inside the CatDV window or opened separately.

Interesting development :

When I switch the setting in the ‘Advanced Media handling’ prefs for ‘Resolve data references’ and ‘Set high quality flag’ to off (deselect) the media plays fine in the details panel. It still doesn’t play correctly in the separate viewer.

Cheers
Carsten
