I've been having a problem with DVE type effects, 3d warp or Picture in picture, for example.  Real time they play back fine, but when rendered, a black bar at the edge of frame or a bunch of lines running through the picture will appear seemingly at random.  Footage might be fine for three seconds, then a bar for a few frames, then fine again for five seconds, then a bunch of lines.  I attached a picture as an example.  Has anyone seen something like this before?

You may want to run a system test. It sound to me like one of the boards has gone bad. Or maybe needs to be reseated.

Thanks for your suggestion.  I tried reseating all the cards/boards in the pc and i/o box, but problem remains.  It does seem like a bad board, although according to Avid System Test Pro (6.0.0) everything is ok...

Seems indeed that the 3D board is not healthy !

Maybe a stupid suggestion, you say unrendered FX do not show the problem, you only notice them once rendered ! How will a mixdown react on an unrenderd FX ?

Intermittent problems.. nothing more fun then that.

Did you re-seat the daughtercard on the DMB? Actually remove it, and re-attach?

And passing the test doesn't mean it's good, it means the intermittent issue wasn't present that moment when the test came through.

And Sep is right, his suggestion is stupid. :-)

I love you babe !

I only reseated the PCI cards to the motherboard and didn't remove any daughtercards.  I'll try this tomorrow.

There must be a clue in that it doesn't appear in real time playback, only when rendered.  Does anyone know how the pipeline differs in this case for say, a picture in picture?

Unfortunately I wasn't able to remove the daughtercard from the DMB - couldn't remove the double sided plastic pegs holding the boards together.  May have to send this one in for service.

I have similar black lines problem at the moment, I ran "Avid System Test Pro" and "3d Effects Board Set" sometimes passes the test but sometimes it fails. I wonder how you could solve the problem. Was those black lines caused by broken board? Your answer will  help a lot.

If you get intermittent failures during the test, the board COULD simply need to be reseated. Have you tried that?

 Yes, we reseated the boards (Digital Media Board, Video I/O Board, Display Controller, 3D Effects Board Set )  firstly, it didn't help,

we replaced 4 electrolitic condansators on the 3D Effects Board (220UF, 6.3Volt) but the failure continued intermittently.

 When I run "Avid System Test Pro" it sometimes does not detect some of the boards, sometimes it detects but some tests fail and every time different board's different test items fail. In this case I can not clearly identify the faulty board.

Did you get the problem resolved? And what was the issue? I have seen similiar issue and can not fix it.

You need to check in your General settings to make sure that your Render aperture is set to the same size as he resolution in which you are capturing.

 

This black bar is happening on a meridian symphony.I did not see a render aperture in the general settings. We are capturing SDI only.

So Sorry. I thought you were referring to more current software.

Is your black bar only on one side or do you have thin bars on left and right?
