Downconvertion problems
Posted by Steen Linde on November 4, 2005 at 1:27 pmHello Luke!
Any news about the downconvertion problems with your decklink cards.
So far we havn`t found a method that can downconvert HD to SD without a very blurry look or with interlase problems.Non of your cards can do it.
Yes we have tried to downconvert through compressor 2, but it will take our apple dual 2ghz about 1 month to render 130 minutes of HD material, so that is not an option. It seems that its not possible to make an easy downconvertion at all, right now. Can that be true?

November 10, 2005 at 12:58 amWe’ve been moderately satisfied with the card downconvert. I wish that it would have a “crop” option along with the letterbox and squeeze. That would be awesome!
We are really having problems with the built-in downconverter on the VideoHub. We lose embedded audio when using this feature.
Because we need to crop, we usually do a deck to deck dub using the SD option out of the HDW-2000. We also just invested in an AJA RMH10(?) down converter.

November 10, 2005 at 8:38 amWell, we tried the AJA HD10MD3 downconverter and it does a beatiful job.
Everything is sharp and there’s just a little bit of aliasing. Only on straight vertical lines such as doors, windows, corners of buildings, etc.
It’s definitely within my tolerance for what’s usable…. and right now, BlackMagic cards just doesn’t cut the cake, unfortunately.
I really hope they’ll sort this out in a hurry.

>It’s definitely within my tolerance for what’s usable…. and right now, BlackMagic cards just doesn’t cut >the cake, unfortunately.I’ve been reading the Cow for three years, and this has finally made me post. *This* has got to take the cake. Comparing a $1,900 stand alone downconverter to a framegrabber whos most expensive version is only $1,500! Talk about comparing apples to oranges!
I wonder, Steen, if you would have been happy to cough up another $1,900 more to buy your framegrabber?
Also, I also own an HD10MD3 and it’s output looks identical to the hardware downconversion on my HD Pro Dual Link – which means that you must be comparing BMD software conversion to AJA hardware conversion.
So, the most expensive BMD card that doesn’t have hardware downconversion is the HD Pro Single Link for $1,000. To add HD capture capabilities to the HD10MD3 you would have to add the Kona LH for $1,800 for a total of $3,700! That’s a 3.7x difference in price!!
I’m wondering if your computer is as good as one that costs 3.7x more? How about your TV? Car? House? Do you own *anything* that can stack up to something that costs 3.7x more?
If you’re going to slam a company, at least have the decency to compare apples to apples!

November 11, 2005 at 1:36 amWhoa..! Hang on a minute, Mike! When reading your post I was just about to really take offense, but then then I decided to take a small break and think this over once more. You know.. consider if you are right and I’m being really unfair about this. Let me try to roll up my arguments as it seems you haven’t been reading ALL posts on this subject. Let’s see:
a. We’ve bought several BM cards and have always been very pleased with not only the quality of the hardware but also with the support we’ve recieved from our local VAR and specifically with the responsivenes of BM to keep the software up to date not to mention adding new and useful features to their products. Being a long time M100 user it’s a completely new experience. So we were very confident that we made the right choice when we decided to buy our BM single link card. Not only a powerful HD card for our HD work, but also for the situation where, (and I quote from the BM website):
“When running exclusively on Mac OS X -
