No I didnt do anything wierd.

From the Adobe site forum – it’s apparently a glitch that came into being with CS3. It has to do with the way PP interprets the footage and handles effects in the backengine.
When CS4 was due for release the issue had not yet been solved (to great outrage according to PP users on the Adobe site) – I was hoping a later patch may have resolved the bug (nothing mentioned on the Adobe site). Or curious to see if anyone else had found a workaround.

You can not see it on your monitor in PP – you only see it when you go out to a full grade environment (or alt can check with a frame still output in photoshop).

The dissolves have horizontal streaks/field lines – even with “de-interlace” on,
Similarly for changes in speed on a clip.

My objective is to have a progressive output from the 1080i footage.
For the grade I was asked to generate a tga sequence of the scene.

It’s like the de-interlace gets turned off under those effects, as the preceding and following outputs are fine.

I’ve noticed a similar problem with field artefacts with 1080i clip speed changes in cs3. Deinterlace doesnt seem to fix it.
Does anyone know if the problem has been resolved cs4 ?
or a suitable workaround ?

Also for motion on stills – get the same problem with interlace lines on the output. Deinterlace has no effect.

Workaround tips greatly appreciated.
