Vegas timeline 8bit: Image looks washed out
Vegas 8bit with Studio to Computer RGB: Image OK
Vegas timeline 32bit: Image OK

Exactly. And this is not a setting problem. Other than EX1 files, all other camera's files that I have tested play correctly from Vegas explorer and Vegas timeline 8 bit with no adjustment.

Glenn, if you wish I can provide you with EX1 MXF and MP4 original files to test.

Thanks again for all your help. Im getting very nice images as a result. Finally gonna be able to render out some good stuff :)

You may notice that Clip browser displays your clip much diffferently than Vegas 8 bit (exactly like your Mainconcept render of 8 bit). So does Sony Clip Viewer on a larger scale. To make Vegas match clip viewer or clip browser (or Edius by default) you have to either convert from studio RGB to Computer RGB or open in 32 bit. Working with the default does not give an accurate represntaion of the original file.

Just to recap I think this quote from Randy is the vital peace of information for all EX1 users.

If you want to work in 8-bit, some other options are:
A- Preview via firewire. (This won't work in 32-bit though.)
B- Use the Windows secondary display. In the settings for that, check color management and the studio RGB checkbox. (May not work for 32-bit, but depends on codecs and what levels you want to work in.)

Thanks Glenn, Im using only one display for everything, Im lookind for a good HD second display though, lets see how that changes my workflow. But for now I think its the following:

Start with doing an unwrap in Clip browser to MXF. Edit in 8bit (for faster preview) and when I start color correction I change the project to a 32bit project. Then I do a render. This way all the formats I need to render to (Mainconcept MP4, Quictime uncompressed and WMV) give desired results. Im happy with how this works now.
