Mac users of AVCHD camcorders can now losslessly edit their video without transcoding it to a more standard format–Neo Scene, a windows app designed for this purpose, is now out for Mac. [Cineform]
(Sorry about this post’s original headline, which suggested this was the *only* thing on Mac that could edit AVCHD. Many apologies, readers.)



Umm. 100% wrong really. As big a fan as I am of Cineform’s products (it’s an excellent RED intermediate codec) this is transcoding software. It does NOT allow for native AVCHD editing. Given the extremely long-GOP nature of AVCHD that would be very difficult (you couldn’t even achieve frame accurate cuts without processing).
FCP’s ‘log and transfer’ function allows you to do the same thing – transcode to Pro Res for editing. For $129 you can transcode to Cineform’s own (excellent) codec, and get a cool progressive look from your crappy compressed HD footage if you like. Yay!
A correction, please Rob?
Or, you know, just use iMovie. Or Final Cut Express. Or Final Cut Pro. Lots of AVCHD support listed on this page: http://support.apple.com/kb/HT3290#2
Did you actually look at the page?
“With Neo Scene you will convert your difficult-to-edit HDV or AVCHD camera footage to CineForm AVI files and then benefit from the same theatrical quality format and real-time editing performance as professionals.”
i.e. it does transcode, it just does so losslessly.
