HDV to DVCPro HD

[Steve Connor]

[Lee Burrows] “Hey Steve. Have you ever gone from HDV to SD DVD?”

Just finished a couple of projects that went to SD DVD, it mostly looked great using compresor presets, however there were one or two shots that had high detail, that showed artifacting in SD. Not enough to warrant spending time recompressing, but I could see how it might me an issue in some circumstances.

BTW I have just finished an edit on a docco series for Discovery that has software downconverted HDV shot material alongside Digibeta footage in SD with no problems at all on delivery.

I think I will go with the a converter box. NickNow a wuestion is

How does this sound.

HDV component out to the AJA HD10A HDTV 10-bit Analog to Digital Converter
the SDI out of the converter to the Kona 2 card and the capture at DVCPro HD format.

Shouldn’t this work?

Converter is only $75 per day rental.

Now a question is…
Does the Miranda and the Convergent converters do a better job? Have you tried these Nick?
I believe those boxes go firewire into the converter and then SDI out.
How does machine contraol work?

hi, i come from germany and we got the miranda converter for one week.
the video-stream looks fine at a conversion. also the audio-stream.

but we had many tc-problem. the miranda-converter detects the automatic
start/stop-signals from the hdv-tape, which was played with the HVR10.
at these points the miranda set the tc back to “0”.

we did a 1:1 copy from the hdv tapes to hdcam with a new timecode.

if there is an other way, to handle hdv without mpeg2, say it to me 😉

Paul,

i havent tried the converters.

in fact the Convergent box isn’t even shipping yet, so i think think that was a bum lead, unless you want to wait for January.

the Miranda works the same: HDV in via FW, HD-SDI out.
Machine control is ALSO via the camera/deck FW port (Cam > Miranda, then RS422 Miranda > Kona card)

i havent seen the results, but it makes sense to me that this path would look better than going component.

a tech guy i was talking to said the miranda had limited frame rates, but that could mean no 25 or 50 for us PAL users?

hang on…

i’m just checking the Miranda’s “compatibility chart” pdf, and it says there are “Major Bug Issues” between the box and FCP 5.02
specifically:
“The Timecode is jumpy with wrong values when exporting to HDV in 50Hz and 60Hz”
but you are exporting to HD-SDI, so maybe you’ll be ok?

i think you should start talking direct to the companies.
Convergent maybe able to help you out with a pre-release version,
Miranda may be able to clear up what they mean with the “Major Bug Issue”

good luck with the project,
nick

[Shane Ross] “DCVPRO HD is an 8-bit codec…but as I said, they might have captured it as uncompressed HD.”

all “shot in camera” tape formats are 8bit.

[Steve Connor] “No RS 422 on HDV Decks!”

Sorry Steve
the HDV deck from JVC has 4:2:2, now if 24p worked in Final Cut.

I didn’t know that – but if the HDV footage is shot on the Sony then that’s no use as the JVC only seems to play JVC shot material!

I liked Thrillcat’s idea about transfering the HDV to DVCPro HD via component I have the 1200a in house so I will try it. If that works the Sony Z1U is for sale, looking at the new Pana200 to match my Varicam.

I think I read somewhere that someone was able to use firewire machine control while capturing over component with HDV. Personally I would do do the conversion in software.
