So I try to hook up a CRT in composite to help guide me on safe afrea and proper colours for grading, but all I managed to do was fail and screw up my LCD composer window!

I have a weird jittter at the bottom of frame on moving video (only).  The source/record window when playing shakes from left to right.

I've re-installed drivers, checked connections, removed the card, but it is still there with the same settings as worked well before I touched the TV.  I have tweaked the hardware accel to Avid 'mid range' compatible spec and have 'pictures in windows when you drag' off.  I've tried both drivers that are in the Utilities folder of Xpress Pro 5.6.6, but neither cure this now.

Its a Quadro FX1500 - standinmg by for MC2.8 on Monday upgrade :-(.  What could it be?  Does 'keystone' mean anything to anyone?  Just a hunch - but, of course, as usual, not QUITE enough info from the manufacturer...

It's even affecting the DVD export :-(

Thanks for any help.

 as far as I know keystoning refers to the way videoprojectors are able to correct the projected image on a screen that is at an oblique angle to the projector. I.e. the projector uses the opposite oblique angle to counteract that screen angle. I don't know if your computer has the option to make such a correction. If so it might be the reason that the upper and/or lower scan lines (which contain coded non visual information - the jittering lines) are visible.
That that is reflected in the dvd is not explained by that I think. But a simple crop of the dvd image should solve that.

 questions:

1) How are you getting a composite signal from the composer to the monitor? The only way to do that is via a deck or a mojo. Or do you have another system with a different b/o box?

2) whe you say DVD export, what kind of export? Are you exporting to a tape then bumping that to DVD or are you exporting to a file then burning a DVD? other?

We need to determine if the video errors are happening inside the machine and IN the project or if they are happening outside of the machine and after the project?  It sounds like they are happening in the project, in the machine is that correct? AFTER you capture and are editing you sequence, are they happening IN the project? And you say they are on moving video only... please tell us what they are NOT happening on?

 Also, keystoning is usually a manual setting that is done on the monitor itself. It should not affect the project unless you have found some setting on the video card that is changing everything IN the project. BUT the description of wiggling video does not at all sound like a keystone issue.

And on more thing, dont use the latest drivers for the video card -- use only the AVID spec drivers -- very very different.

3) What did you change when you hooked up the CRT? Did you ONLY plug a composite cable in? Or did you change other settings?

We need all this info. And what do you mean by standing by for upgrade? Changing full software mid-project is recipe for messing up a project. AVID pros may tell you otherwise but I know from experience and the words of 10 editors who all say the same thing.

Hi Guy.  Thanks for the help.  I dont think it is anything to do with Avid.  It played an old QT movie and the bottom of frame shaking from left to right.  Have uninstaled the driver (all versions tried) completely now and all looks fine using basic windows driver and playing the QT file.  I WAS getting artefacts on a 3D page turn on the burnt DVD though.  Really dont know what to try as I've tried both drivers in the Avid folder.  Re seated GFX card and checked the 'read me' avid settings for V 5.6.6 Xpress.  It was all fine till I hooked up the b telly!

 

1) How are you getting a composite signal from the composer to the monitor? The only way to do that is via a deck or a mojo. Or do you have another system with a different b/o box?

My Quadro card has 3 outputs - 2 x DVI & 1 x composite/S Video.  I hooked up a CRT to the composite S Video (via the little breakout box that comes with the card).  I was half hoping the 2 DVI's would keep going (I'd be lucky!) but never saw anything on the TV.    I digged deeper to switch from default NTSC to PAL etc, but the card seems to think everything is HD TV...  Too much digging involved so let it go, for now.

2) whe you say DVD export, what kind of export? Are you exporting to a tape then bumping that to DVD or are you exporting to a file then burning a DVD? other?

Export file via Sorenson (and there is another story my 'bought in 3D GFX are so aliased and jittery - still burning with different settings again and again...)

We need to determine if the video errors are happening inside the machine and IN the project or if they are happening outside of the machine and after the project?  It sounds like they are happening in the project, in the machine is that correct?

Jitter is visible in Avid on both of my monitors and on moving pictures only.

 Also, keystoning is usually a manual setting that is done on the monitor itself. It should not affect the project unless you have found some setting on the video card that is changing everything IN the project. BUT the description of wiggling video does not at all sound like a keystone issue.

OK

And on more thing, dont use the latest drivers for the video card -- use only the AVID spec drivers -- very very different.

That'll be the 84.26 vers I need to use then - rather then the later one ALSO in the same folder (that worked fone!)

3) What did you change when you hooked up the CRT? Did you ONLY plug a composite cable in? Or did you change other settings?

I tried to force it to see the TV ra\ther than default to this HD TV nonsense.  One of  my DVI monitors was left unplugged to help it find this.  Manually I eventually got to composite PAL, but nada...

Yes that's why I have held back really..have enough hassles at the mo!!!

Thanks for any help as I am out of ideas (although thankfully it is not affecting my DVD's for tomorrow's delivery day)

Hi Guy - I still have this issue.  Any other insight is therefores still molst welcome!  Thx
