Any trick in getting HDV to stop conforming when outputting through Kona 2?

Get the client to shoot on HDCAM or DVCPro HD maybe? 🙂

What do you mean get the HDV to stop conforming when outputting through the Kona 2? What exactly are you trying to do? You can play out your HDV timeline directly to HDCAM via HD-SDI, but it sounds like you don’t want to do that.

Ha! I wish! All I can say is at least the XL H1 has HD-SDI out. Now, let’s get that functionality in a reasonably priced deck. No matter how much people love the HDV, it’s been a thorn in my side :>

What I want to do is Edit to Tape an HDV timeline to HD-CAM, using the Kona 2 to upres the material. What I don’t want to do is sit for 6 hours while it conforms a 2 hour concert.

I did a test today using a DV-CAM deck and the analog outs of my Io box which were fed by the Kona 2. It wanted to conform on ETT. So, I’m assuming it does the same thing when going out to HD-CAM via HD-SDI.

I want to start a “Just Say No” campaign to this conforming craziness.

Thanks,
Michael

No, the Kona 2 does not do the same thing. It performs conversion on the fly in realtime. The Io is an SD ONLY box so anything that starts as HD, must be rendered to SD before it can play out.

The Kona 2 is an HD/SD box with realtime up and down convert. Your HDV timeline will play out to the HDCAM deck in realtime just like I play out my DVCPro HD timelines to HDCAM via HD-SDI on the fly. You can also play it out to Analog SD in realtime either using Composite or Component from the K-Box along with the RCA audio outs.

Do you not have the K2 connected directly to a monitor somewhere to see that it’s playing out HDV in realtime?

Sorry if I didn’t explain myself well. I was sending the Kona 2’s SD-SDI Out as a feed to the Io. I use the Io as a converter box so I can feed my SD waveform monitor. I know I could use the K2’s composite outs, but I just happened to have everything set up this way so it was easier to do the test this way. I would never do a broadcast output with the Io because of the frame lag.

Yes, the HDV footage plays from the timeline with no big to-do. It’s only when I edit to tape that it wants to conform. I will be able to test this out with a direct HD-SDI cable and an HD-CAM deck on Saturday.

I’m assuming that it will still want to conform, but I’m hoping that’s just not the case.

thanks again,
Michael

[Michael Garber] ” I would never do a broadcast output with the Io because of the frame lag.”

you can adjust the lag.

if you are working in HDV what settings are you using?
I use the 1080i60 8bit easy set up and I do not have any issue with conforming when I do edit to tape.

I render the project and play out to tape.

Absolutely. The Io is used for braodcast every day and I just added the Io LA. The Playback offset needs to be 5 I think for FCP 5.0. Once the offset is set correctly, the NTSC output and the Canvas will be in perfect sync.

Hi,

I have a similar problem. I can edit a HDV timeline and play out real-time through Kona2 as I am editing, but when I go to do an “edit to tape” to a SONY HDW-500 HDCAM deck FCP wants to conform the timeline before output. My Timeline is a “HDV1080i60” and my Easy Setups is “KONA2 1080i 29.97 8bit”. Is this the correct easy setup???

Did you guys agree that an actual “edit to tape” could not be performed in the scenario without the use of an AJA Io as well???

Thanks,
Craig

I don’t have first hand experience with HDV, but it is my understanding that while the Kona 2 takes some processing off of HDV, the i frames still need to be reconstructed at cuts/dissolves before a final output to tape. This is one of the hinderances with working in the Mpeg-2 GOP based HDV codec.

If you’re working in HDV and you use the native codec in FCP, then it has to conform at the end before it can output. Among other things, it has to put I-frames at all your edit points, etc. This takes time. The alternative is to use the Intermediate codec, but then the quality is reduced and the files get bigger. HDV isn’t a miracle format, it uses MPEG-2 which is Latin for “Tradeoff”. If the Kona2 does this without having to conform then I will be amazed… and be buying one immediately.

Hi,

It only needs to conform during an “edit to tape”. A straight play off the timeline to HDCAM tape looks superb, no conforming or rendering.
