ki pro mini & convergent nano flash
on Feb 25, 2011 at 9:18:19 pm

Not to be camera specific as there are already too many out there, with aja coming out with the ki pro mini and convergent already with the nanao flash; what are the key pros and cons of the two recorders? How flexible are they to use with Sony, Panasonic and the other HD cameras out there? What would someone suggest going with? I've got an FS100 which was great and was out there prior to Convergent and certainly AJA.

The Ki recorders record in Apple's 10 bit ProRes codecs.

The NanoFlash uses MPEG2 based codecs, which I think are all 8 bits.

Both ProRes & MPEG2 based codecs are pretty widely used.

NanoFlash records into long GOP codecs. While this is great for drive space, and looks pretty good when viewing, long GOP codecs degrade in post. Visual Effects, Renders, and all around computer speed take a hit when using these.

ProRes, is not a long GOP codec, and holds up great in post - but at a price - it eats up space.

I recommend ProRes 422 or ProRes 422 HQ.

At it's top data rates, the Nano can record an all I-frame version of MPEG2. But I think the data rate is something like 200MB/sec or more, similare to the data rate of ProRes or PorRes HQ.

Like it says above...apple prores is great but eats space. If this helps your consideration, we distribute media to HUNDREDS of outlets ALL OVER THE COUNTRY AND WORLD on CF cards recorded in our nanoFlash units, and no one seems to have a problem. While there is a codec for prores playback available to Windows users, it is, as far as I know, Player only. We have had great success with nanoFlash compatibility.

Another note, I have been told you can have the best of both worlds. While re-encoding your raw long GOP footage will not improve the quality and just consumes drive space, in Final Cut you can create a Sequence that is prores, and use your XDCAM EX footage from nanoFlash. It will edit fine, and when you render final sequence, all will be prores, leaving fewer artifacts. Honestly, I never see any problems in my native timelines either, but I hear a lot of concern about it.

Bottom line (in my humble opinion) HD video is always compressed for distribution...period. Blu-ray is, cable and satellite are, and so is every cloud based distribution (i.e. web viewing) You don't want to step on quality too much, but if you can't see a difference in the edit room, don't lose too much sleep over it. 25 years ago one of my early mentors told me, "This is a great business, there are no rules...if it looks right, it is right." Of course, he was referring to the new styles of shooting and editing that now seem common today, but were unorthodox back then.

Michael,
Thanks for your reply. Obviously the future is an unknown as my investment in the firestore is proof of that and the ki pro mini is fairly new on the market, but which would you consider a better investment. I primarily shoot with the Panasonic HDX900, but would like to know whether which would work better with the other cameras such as Sony and the various large format cameras.
Would they both upload easily into FCP and Avid?
Thanks

Although the Ki Pro Min is new, the Ki Pro Mini is based off of the Ki Pro, so I think it is a little bit more developed than a brand new product.

FCP will use the ProRes generated by the Ki Pro Mini 100%.

Avid 5.0+ can use ProRes via AMA, and is actually BETTER for Metadata retention than doing an traditional import.

ProRes will serve you very well, IMHO.
