NOW I HAVE THE JITTERS

[Rhewitt]

Are you seeing jitter in the whole frame of just on fine horizontal lines?

[Mcqueen]

Not sure ahat you mean. It is an up and down Jitter as opposed to a side to side Jitter.

[McQueenUk] “as opposed to a side to side Jitter”

Which, I believe is called ‘judder’. No kidding.

If you get jitter on small lines, you’ve encountered a limitation of NTSC – it can’t resolve (very well, at least) lines of 1 pixel. If you have lines coursing through the picture, especially through motion, its probably the result of looking at an interlaced product on a progressive (computer) monitor. Try checking it out on a interlaced monitor and see if you get the same thing.

HTH,

Jon

[Galen Yeo]

this could be a bug. how are you importing? over a network?

[Michael Hancock]

Check your field order on import. If you’re importing it lower field first, try changing it to upper field first and see it that fixes it.

I am working in PAL and with version 4.6 of Xpress pro it was lower field first so I thought it would be the same on 5.7 but it is not. As you rightly suggested it is rock solid on upper field first. You think they would let you know.
I am still having problems importing anything that is not 720 x 576 in DV. My stock aniimations are prepared as 1024 x 576 uncompressed AVI’s with alpha channels so that they show the correct aspect ratio in widescreen but can’t get them to import.

DV Pal is lower field. doesnt metter the version u working on.
and the frame size is 720*576. basicly if u want to get the wide screen u should crop the picture (16.9 mask) in Avid or crop it in AfterFX and export as Pal dimensions. Avid like to play with QT or TIFF\TGA Seq more then Avi with alpha.

I was always under the understanding that PAL was Lower Field First until I met AVID.
My first version of Xpress Pro 3.5 I think was Upper Field First then when I upgraded to 4.6 it was Lower Frame First. Now with 5.7 it is Upper Field First again.
I am still using the same versions of QT and Windows Media Player so it must be Avid that have changed again.
This of course means all the stock titles etc that I have are all useless. Still having problems importing uncompressed AVI’s and QT’s in any other resolution than 726 x 576 in a DV project. In 4.6 I made my widescreen titles/animations 1048 x 576 and never had a problem.
I spoke to an avid sales rep recently and he referred to Xpress Pro users as the lower end of the market. This sums up Avid.

i dont remmember the field order in version 3.5 was upper and i didnt met version 5.7 yet, but i cant believe what u seying here about changing fields order. have u tried to post it in the Avid forum?
All the other versions im working on is lower unlike ntsc which is upper.
please come back to tell us more of what u found.
GoodLuck
