hi everyone,

thanks for all your help! Totally appreciate that having 'output frame size' unchecked will push the ds render times, however it is a necessity:

hence my next question:

When using 3d DVE it seems to automatically check the 'output frame size' box. How do I uncheck it as I would like to go in close and keep the high res image and animate it out to pal frame size??

Thanks in advance

judicious use of cache nodes

Note however that Cache nodes only hold a cache at Sequence size, so if you have Output Frame Size turned off, a Cache node won't be of any use to you at that point in the tree.

Try it and you'll see that although DS will appear to process the node it will stay red.

I bet I could rebuild your tree with it turned back on for 90% of the nodes where you have it turned off ;-)

Correct.  The 3D DVE isn't resolution independant on its output.  You must therefore use it AFTER your larger-than-frame-size nodes.

However, if you feed the 3D DVE with a large linked image you can zoom right into that image within the 3D DVE with no loss of resolution - it's only its Output that is fixed at frame size.

I'll repeat what I said several posts ago - rethink your tree to turn OFS back on for the majority of your nodes.

Let me give you an example.  I have a 4k image right now in a PAL sequence.  I'm using a Linear Luma Keyer to create a matte of that image.  That node has OFS switched off.  I'm following that node with a DVE to move the keyed image around the screen.  That DVE has OFS switched on because I now only need the output to be PAL sized.  I've finished with my operations on the 'large' image once I've created a suitable matte for it.
