Curing the diagonal blocking problem at DVinfo.net

Wayne Morellini · September 18th, 2006, 11:50 AM

I remember reading people getting clean video without the diagonal blocking problem when playing back through component from the camera.

There is a new HDMI input output capture card by Blackmagic design called intensity. People have been talking about using it with a component+audio to HDMI adaptor to capture from component enabled cameras. There is yet to be confirmation that the HDMI card will work with an component converter at all, let alone wherever it will produce a good result and sample at the true resolution, let alone it will work with a HD1 at all.

This would enable you to capture without the problem edit and finish. Of course you would use an intermediate codec, like cineform, or the ones provided with the card. It would be worth checking if the photojpeg could work with Cinelerra (Linux and free).

You wont get any more quality, except you get rid of the diagonal blocking, it will still be compressed quality. It might even be possible that the recompression might loose some additional quality.

Now, I have seen a picture of a portable component out for Xacti cameras, attached to the base. I am wondering if this might give a live uncompressed output?

Now, the down side, it's not cheap, around $250US for the Intensity, and around $179 (reported for an unnamed adaptor) or $199 for the component and audio+HDMI adaptor (NLE and other codecs extra). It could be used for future HDMI camera. But note again, we do not even know if this combination will work yet. So, caution, it might not even work on the HD1.

Well, I hope this helps you guys.

There's also a new $1000 HD Studio card from Decklink that captures Component I believe. It may seem like a lot compared to the Intensity but historically that's pretty darn inexpensive.

So $450 for Intensity+Converter (will it even work and if so how well) or $1000 for a card that does it... I'd probably just go the HD Studio card route. But it'll be interesting if someone tries that combo out.

And the HD Studio card also includes the HDMI functionality of the Intensity.

I see no reason why it shouldn't work. The converter box just turns the signal into a standard HDMI signal so you could hook whatever device you have to a HDMI port. The Intensity card just captures a standard HDMI signal from the cameras or other HDMI devices. The only problem is copyright signals. I'm not sure at this point but maybe the converter box witll add copyright to the HDMI signal which means the Intensity could would not capture. If the box does not do this then it should work fine.

As for the quality well that would depend on a analog to digital conversion of the box itself. Since these things are meant for HDTV's I'm sure they look pretty good. Is it good enough for a master? I do not know.

Just one other note for PC users.

The Intensity card uses a PCI Express x1 slot which every single newer motherboard has.

The HD Studio card with component needs a PCI Express x4 slot which are only on high end motherboards. Sometimes you can use the second PCI Express x16 if your board has two of them for video cards. Some SLI boards may have issues however since the slots are designed to work together for two video cards.

Oh, no, this thread was supposed to be posted to the Sanyo HD1 forum, sorry, to solve a problem they have with the cameras recorded footage. Can the moderator move it there?

Thomas, they have motherboards with 4 sli PCI Express x16 slots now (crazy I know, I don't remember wherever I heard more than this, and estimates of the next ATI Direct X 10 cards are running into 250watts each, ouch).
