If it's not mentioned yet. I need Openexr image sequences. Lightworks could well fit in my 3D/compositing workflow made in maya/blender/nuke and keep everything in 32bit. Then finally I can stay on my Ubuntu box without ever use my mac again.

This would be terrific and I wouldn't mind paying like for DNxHD.
Thanks for going the opensource/linux route!
dreh

Yup, as mention before again and again Openexr with custom multichannel support is essential for many people, otherwise Lightworks is just another editor. Also a good exr and importation workflow for those using Modo, Lightwave, Maya, Max, etc.

Being just another (awesome) editor is actually what it should be.
I'm all for OpenEXR support (very useful to be able to test your renders in your edit without the need to convert them to another format) but I don't see multichannel support as essential, quite the opposite. LW is an editor, not a compositor. Multichannel EXR files are huge and would slow any timeline to the point of being unusable.
What would people use multichannel EXR for, in Lightworks?

One more vote for CinemaDNG.

People read the topic again ".. formats users need first..." That is which should be a PRIORITY, not which would you find useful. There are developers working on this so let's get them to Prioritize most effectively!
And honestly do you need a poll for this?
Just look at the dominant codecs in acquisition and Post.
ProRes, DNXHD, AVCHD, DV, HDV, R3D
Know which ones are important and which ones are headed to the dustbins of history. A poll is of limited utility since only people already interested in your software will participate. I am guessing you want to address the need of people beyond your fanbase.
A priority should be to create a mechanism like Avid's AMA that let's others write codec support without requiring it to be coded by Lightworks developers. This way you can concentrate on the core capabilities of your product.
As for Codecs I'd like to see but not prioritize:
Cineform at least decode if not encode, Dirac, Ability to create DCPs

OpenEXR is non-essential. It would be a cool feature to let the source OpenEXR passthrough Lwks to the colorist for extremely accurate correction.

MKV would be nice for all of your home movies and pirated films/TV shows. It is not an acquisition container and provides no benefit in being one so what's the point of it being a feature in a pro NLE?
