Recording uncompressed from HDMI output on HV30...

John Yamamoto · July 4th, 2008, 06:00 AM

Hi
I find out that Quicktime pro can capture on osx
but same issue, as u can only choose intensity native which is uncompress
my HDD also not fast enough to capture 25FPS ( i m using PAL HV30)
seems HDMI is very promising, video and sound all capture, and perhaps a portable raid system may help. i google some but yet to know which is best option.

on PC -i can use XP and set at MJPEG, but as codec itself may not be as good as uncompress, so far i dont see any capturing software supports other codecs like cineform or anything with intensity/HDMI

how Intensity compares to nanoflash? compression wise

So i just tried this weekend. Blackmagic intensity over HDMI from HV20. Captured to MJPEG. We also used a XHA1 captureing to tape. The footage from the XHA1 to tape still looks so much better than the HV20 MJPEG even though the uncompressed signal mayb be better for composites.

John,
On OSX you can capture to ProRes for great quality and good compression.

Tyson,
In what way was the image better? XHA1 has much better glass and better manual controls, etc., but the imager in both cams is the same. Properly set-up, you should be able to get very comparable results.

Can you comment on these turnkey solutions? How would ProRes or Cineform for the Laptop option operate in the workflow? Thanks.
