So whats the difference between using premiere pro/media encoder to encode files compared to using HDlink or neoscene?
Is the something happening to the file? I kind of liked having that external program to encode a large number of files.
If i use media encoder to convert 30p to 24p is that the same as using neoscene?

Cineform used to be the standard for turning 4:2:0 HDV into a 4:2:2 intermediate with the chroma interpolation built into the conversion. You get a nicer looking image from 4:2:0 material, but likely all of that is about to go by the wayside nowadays.

RGB24 is very common in VFW, but not the most efficient for compression. YUV through VFW is tricky, but better (faster.) We also implemented v210 -- 10-bit YUV through VFW, I know VD can be made to support it. Unfortunately I don't have hands on experience with this type of capture.
Is this something you could answer? thanks!

They should be very similar, however I don't have access to the internals of Premiere, if you are using YUV 4:2:2 the result should be the same (I believe Premiere does 4:2:0 to 4:2:2 up conversion correctly for some time now.)

30p to 24p is never recommended. Neoscene had a pretty good 60i to 24p, which is still uncommon in other workflows (you could hack something together with AVISynth)

Great interview with David,
May fill in a few blanks for us. Sorry for giving you guys so much flack earlier on. Personally thanks to the Cineform guys - this video helps me at least understand your goals. Perhaps we shall see a flavour of VC5 in cameras in the next few years. Blackmagic could really take a hint here. I would still love to have a separate version of Firstlight hint, hint.

Nice to see what you GoPro and David Newman got in mind out there. I have been using Cineform from HDV days on, and it continues to be an excellent intermediate editing codec for me in Vegas Pro. I think this is really the first time I have seen David Newman in an interview, and it was a pleasure to see that he exhibits such enthusiasm about the product. Thank you all at Cineform and GoPro for the moves you are making to standardize Cineform !!

Just watched the video. I don't think that the standardisation of the codec will have any impact at all. I don't know of any one who is developing there own codec. They are more likely just to licence a codec from Gopro.
Another issue is the lack of hardware acceleration for the codec.
My main interest is 3D which Cineform seems to have abandoned. Adode does not support 3D and Gopro Studio cannont even multiplex or demultiplex the left and right views.
Gopro Studio is too crude for serious video editing. It seems to me that Vegas Pro is the only editor supporting Cineform 3D.

Just bout 2 months away before Prem/Prof Cineform goes away for good....
Still haven't found a decent alternative to capture directly to CF without HDLink. At any rate, trying to future proof my system for the near future with new gear. I'm hoping at some point some company or someone will support it or have it available as a native codec for capture. In the meantime, backing up all my system drives (cloning) in case it ever goes south on me. However cross my fingers that my new system doesn't die on me then its goodbye CF Prem, for good.
In case anyone is wondering, the new Blackmagic Intensity 4K capture card works no problem with the last version of Cineform Premium/Professional using the latest BM drivers (10.5 I believe). Depending on what kind of source material, you can feed and capture directly to CF at much higher resolutions/frame rates than the previous versions.
