Having a little trouble with some content - its about 32M, so cant post it - but it?s a simple movie file - it plays ok in Quicktime, but in catalyst it gets sliced diagonally and the left and right side is swapped and mirrored along the diagonal - hard to explain - will add a snapshot asap - few shorts of the working clip atached... Any clues?

Aha i think i see something from this.

you cant create a dv movie at 369x429...
they are always internally 720x576 or 720x486
quicktime cheats. i ignore this cheat.

if you actually need a 369x429 movie then you need to use photojpeg ( 50-60% )
otherwise create the dv movie at overall size of 720x576 and have a black outline.

beware also that 720x576 - has NON-square pixels - but i ignore this too, as my aspect ratio channel allows you to alter this live.

Actually, yes - I figured this out too by reading another thread about best formats....

http://chaldee1.gotadsl.co.uk/~richardb/upload/showthread.php?t=111&highlight=formats

PhotoJpeg or Mjpeg would solve it I think - as the former will recognise 'odd' resolutions.

However, I think our best idea will be to use DV-Pal with a black border in the content - or we might run in to other issues of xfading between different formats - and I;ve always seen dodgy 'steppy' fades in that scenario

I've put the original content on:

but beware - it is 20MB...

you are much much better off creating the smaller size movie using photojpeg, as photojpeg performance is much better than dv with smaller size files.
and photojpeg is also a much better codec at smaller sizes because it has better colour resolution than dv.

almost all fading issues come from the lighting consoles - not having outputting dmx smoothly enough or regularily enough.
content has nothing to do with this.

I would always use Photo-Jpeg. It is the ultimate Media Server codec - it has no fields and gives better colour than DV.

dv performance is better at standard definition sizes.

Let´s tell all the designers that go for standard size (Joking!!!!) ,

How about the best codec for really strange sizes (like: 2048x188, etc etc)
My experience tells me that still Mjpg A is the best solution, with no scussi disc´s, just FW stuff. Often the supplier just has a Cat with FW disc´s or inside a barracuda or standard SATA drive.

DV should be the best, most layers stabile at 25fps, but the size is fixed and it never looks good as well (something with text just sucks!!)

Will be cool to see perfomance with h264.......

h264 dreadful for this kindof thing.

uses interframe compression.

Peppe,

Tsk, Tsk! Interframe compression. Wash your mouth out with soap and water!
