Disclosure: I have nothing to do with the GoPro/ Cineform company and was ready to abandon them for use in Vegas 11.
BUT the new Cineform Studio is a perfect mate for Vegas. Mr. Newman worked with Sony to get every thing working. Yesterday I spent 8 hours editing without a crash or any hick up for that matter.
The new ingest module took my hacked (really big GH2 files) and rendered them to the CF format very well and the edit mode provided a true WYSIWYG interface with Vegas (ver11 64bit). The edit module allowed realtime correction updating to even my subclips.
I own Neo so I hope I don't have to pay more for the new version.
I really recommend that all vegas users give it a try (see the CF secton below for free trial)
I have never publicly endorsed anything in my life before now. You really owe it to yourselves to give this thing a spin.

Roy, thanks for the info. I've been using HDLink for awhile and it's very useful, if you need it.

It's important to note many if not most people do not need Cineform. I only use it to convert mixed footage most of the time.

Every day I usually have a 4 camera hd project in process, and while Cineform files are easier to edit, I don't bother converting, it's not worth the hassle most of the time.

When I do use it, it is extremely useful, but rarely do I need it anymore. One video takes up 750GB after converted, and that is too much most of the time.

Glad to hear the new product is so good!

I use to convert everything in the past but had so many problems I stopped converting to Cineform and surprisingly everything worked great since however I do render my master output to Cineform for archiving & transcoding. Bought a brand new Intel i7-2600, 16Gb Ram upgrade today but haven't had the time to install yet, will give Cineform another try on my new system next week sometime. (Neo owner).

as and when i have to transcode 'awkward' footage i usually do so to mxf. never had a problem and vegas seems to love it.
