Please explain Cineform Neoscene
I currently use a Sony HDR-CX500V camcorder and record in AVCHD 16 mbps 1920×1080-60i. I haven’t had a difficult time in editing my footage. I am considering upgrading my camera to the HDR-AX2000 which records AVCHD at 24 mbps. I wonder if the editing may get a little more tricky with this resolution? I have heard others saying that Cineform Neoscene is helpful for editing.
I am not exactly sure what Neoscene does. It sounds as if the footage is converted to a more usable/friendly format. What is the format that the original footage is converted to? I generally have been rendering my home movies back to the original format using Sony AVC AVCHD 1920×1080-60i. The media plays fine using Windows Media Player. In using Neoscene is some information lost since things are being converted? What are the file sizes as compared to the original ones? And what format would I render to in using Vegas Pro 10? I’m just looking to understand this a little better. Thanks

Cineform Neoscene gives you a more edit-friendly video format. While technically it’s using wavelet rather than DCT compression, the end result is that you get something that’s more like DV… no interframe compression. Because it’s not another DCT format, and because it’s been highly tweaked for “intermediate format” editing, it has only a very small effect on video quality, versus native editing. Using a different DCT format, like going from AVC to MPEG-2 MXF as some do, can tend to reinforce the DCT compression artifacts common to both CODECs.
The one issue with Cineform is size: you can get about 50-60GB/hour, versus under 12GB/hr for DV, HDV, or 24Mb/s AVCHD. You’ll need ample storage, and if you do lots of video tracks at once, fast hard drives. I have occasionally run into speed problems with Cineform just due to HDD performance, but that was some time ago, and it’s solved by using multiple drives (then again, I’ve also done projects with 40+ compositing layers).
I don’t think the bitrate’s going to matter much… if you’re happy editing AVCHD at 16Mb/s, going to 24Mb/s at the same resolution shouldn’t seem much different.

Thanks for the reply Dave.
I also see that Vegas Pro only goes up to 16 Mbps in rendering with Sony AVC. This is what I have currently been using. It looks like I would need to render to MPEG-2 in order to render 1920×1080-60i at 25 Mbps. I don’t know enough about the different formats to know what this means. The file type that would be generated is .m2v which I am not familiar with. What would be the proper workflow for me in editing and rendering my home movies if I were to upgrade to a camera recording at 24 Mbps? Thanks.

In Vegas 9 you can render at speeds up to 35 mbps in xdcam format. Vegas seems to support any new formats.
