Hello All :-)
I have a BMD HyperDeck Shuttle 2 and it records uncompressed and in the DNxHD (220) codec.
I can import, play and edit the files just fine, but there's a major problem that makes the files useless.
Static scenes are fine except they are flat and require color correction to make them aesthetically acceptable.
The main problem is that the files have horrible interlacing problems... and I'll explain.
First of all, it doesn't matter whether I shoot in FSH, HBR, 24p or don't hit the camera record button at all and just record from the cleaned display... the same problem occurs, so it isn't a camera setting (I've spent 2 days experimenting with different cam settings as well).
When panning I get fine interlacing lines. They are annoying and unacceptable in their own right, but it gets worst. Once encoded (as in for distribution) the problem is accentuated. Huge lines appear and and make the video look horrible... it is unusable.
On close inspection of the files in PP CS6 I can see that the file is filled with ghost images, which I thought were a result of duplicate frames that the GH2 has served to the BMD Shuttle 2.
I've read about certain fixes for this and a the color shift issues, but a) most sound too difficult to be used in a practical workflow and at the end of the day, they may not even work.
So I'm here with hat in hand hoping that a discussion might yield some fruit that can help me, and others that are having the same problem or looking to use a Shuttle with their GH2s.
I said that extra frames were being added, well I read that recording from the GH2's HDMI port added and deleted frames randomly, and that clouded my judgment and made me lean in that direction, but upon closer inspection (I was going to experiment with manually removing the extra frames) I found that there are no extra frames per-say.
The ghosting I described is at the heart of the problem.
When panning each frame appears to be a combination of 2 frames at different times. So depending on the speed of the pan (and the shutter speed - the higher the SS the closer together is the dual images) you get an interlaced image (half of the lines) at one point in time, and another (the other half of the lines) at a later point in time.
Where they overlap, the image is solid, but on either side you have a "ghost" image which when played back you can see through the image where the missing lines are, thereby giving a notched edge effect.
And I haven't even wrapped my head around how I can fix that yet??
Thanks for your interest and feedback!!
