Content Problems

[samsc]

OK,
So I have some content from a client,
I had them encode it in the Photo jpeg codec at 70% quality.
but I am getting Jagged edges every time the video moves.
I understand this is Interlacing jaggedness,
but the person I am dealing with doesn't think photo-jpeg can be exported de-interlaced,

I believe he is using avid to export the content,
Any help would be appreciated, even if it is just instructions on how to export de-interlaced video from avid.

Would using the DV codec help, I was trying to use Photojpeg to get a bit more quality, but if I have to I will go back to DV.

Any help would be greatly appreciated!

interlacing or deinterlacing has nothing to do with the codec -

interlacing is an artifact of the way most video cameras work. If you shoot on film you dont get this - ( unless they do a 2:3 pulldown in telecine )
They dont work at 30FPS they split the image into two fields each 1/60s long - they then combine this into a single frame.
interlaced video looks like this: ( when displayed on any LCD or progressive scan monitor )

Typically - Deinterlacing - is not part of an 'export' process - but part of the effects applied to a layer.
With live action footage - on any post-production software - irrespective of any subsequent use - it will need to be deinterlaced before zooming, scaling rotating, or even shifting..

In final cut - you apply the deinterlace filter to the layers and cliips.
i dont know anything about the avid workflow.

There are more complex software filters available from 3rd parties to do this -
deinterlacing accurately - is not easy or trivial.
3rd party plugins specialised to do this job:
For example the 'Fieldkit' from revision FX
