i recieved my hyperdeck shuttle 2 today and was testing the hv20 with the compressed dnxhd in a .mov container. And have found some problems when editing in premier and was wanting some advice on the matter :

1: i cant use 'maximum bit depth', if i do i get weird blue and yellow colours on the highlights of the clips
2: instead of importing 1 audio track with the dnxhd.mov clips, it imports 6 audio tracks (all the same) !!
3: premier never guesses the field order right when using the dnxhd.mov.. i might manually select "upper field first" when shooting on the hv20.

awaiting your thoughts.


PS: i will say the quality of the video is fantastic !!!
 
I hadn't heard of the hyperdeck shuttle, but connecting the hv20 to an external recorder appears to be an interesting solution.
How do you connect the hv20 (hdmi?)?
Does this enhance significantly the video quality?
Isn't this interlaced anymore

I too recently bought a Hyperdeck Shuttle 2. Although I plan to mainly use it with an HMC40, I decided to dust off my old HV20 to see if it makes that cam viable again. Inspired by the Bolex, here's the rig:

Unfortunately, some personal circumstances have limited my time as of late, so I haven't shot much with it yet. First impressions:

1. Bypassing the tape is very nice. It could be worth it just for that alone.
2. Image quality seems improved over HDV, but I have not done the requisite side-by-side to say by how much.
3. No HDV compression artefacts (obviously).
4. The Hyperdeck doesn't perform miracles. Dynamic range is not improved, and even with the upgrade from 1440x1080 to 1920x1080 the HV20 image is still rather obviously softer than the HMC40 (which is itself getting to be an older camera.) I was hoping to be able to do multicam shoots with the HV20/Hyperdeck and HMC40/AVCHD, but they may not intercut well unless I soften the HMC40's image to match.

I may have time in a week or two for some real tests, if anyone is interested.
 
So interesting to see interest in the HV20 again! It's a vintage modern by 2012 standards.
As you may know, there has been TONS of testing and chatter on HV20.com about external recording benefits.
As I recall, the color space is 4:2:2 which is amazing when you consider a recent release like the Panasonic GH3 is only 4:2:0
You should also be aware that the Hyperdeck shuttle is not the only external recording option/
Removing pull-down is no big deal either.
The only disappointment is that color quality of uncompressed capture vs DV Compressed to tape is only a bit better.
I still have my HV20 and use it when I want that 'vintage' HD look without all that nasty Moire you all get with the pricey DSLR's ;)
 
Actually, according to Dan Keaton of Converget Design, the HV20 is 4:4:4 out of the HDMI. I kid you not.

But the pulldown, at least for me, is a RPITA, b/c the HV20 records outside of the 16 to 235 legal range. While it gives you some more headroom, most pulldown removal programs clip the super blacks and whites that the HV20 records.

The only reliable solution I could find is processing each take individually in After Effects.

Maybe 4:4:4. I have to recheck the HV20.com thread.

Would love to see your workflow in AE, and why would that be different that the tried and true pulldown removal workflows of the past? I simply import into iMovie HD (7) and import the media files in FCP- pull down automatically removed. MAC of course.
 
This is likely of use only to Linux users, but for what it's worth, my own solution for dealing with pulldown is to use mencoder in a shell script to batch-process all of the Hyperdeck files in a folder. I can run the script, and when it's done, all of the clips are converted to true 24p files in mathematically lossless Huffyuv format. The Huffyuv files are much smaller than the pure uncompressed* files out of the Hyperdeck to boot.

This is what I came up with:
mkdir 24pfiles
for mediafile in *
do
mencoder -fps 30000/1001 -field-dominance 0 $mediafile -nosound -o 24pfiles/$mediafile.avi -ovc lavc -lavcopts vcodec=huffyuv:format=422p -vf filmdint=fast=0/io=30:24/dint_thres=256,softskip,harddup -ofps 24000/1001
done

It might be possible to adapt this method for use on the Mac, or possibly Windows as well. There is less need for it on those platforms, though as (probably) better tools already exist. There are not so many people masochistic enough to edit video on Linux, hence the need for the for-mentioned script.

Very true. I think that the Ninja 2 would probably be the more practical recorder to pair with the HV20. Not only would you get the benefits of 4:2:2 and high bitrates, but a substantial upgrade over the HV20's built-in monitoring and exposure tools.

*I could use DNxHD to save space, but I figure that if I'm going to go to the trouble of using an external recorder, I might as well go all-in and use the highest quality format that the recorder supports.
