What exactly AJA Kona TV anyway?
on Jun 3, 2007 at 1:30:20 am

I've been opening .movs from my desktop and playing them through Kona TV/Kona Card to a nice CRT monitor. The quality is great! Before I had to bring these clips/.movs into a timeline in Final Cut Pro in order to veiw them full screen on the CRT.
I'm assuming this is the idea behind Kona TV.
I noticed there isn't much documentation/instructions for it?? Strange.

I haven't had much luck playing .H264 with strange internet compressed dimensions though?
Is there a way around this?
Is there a "missing guide to Kona TV" .

[Michael Pierre] "I'm assuming this is the idea behind Kona TV."

Yep. You hit the nail on the head. Kona TV allows you to play any codec that Final Cut Pro can play out in real time. Web compressed codecs like h264 are not supported, just like real time playback of h264 content is not supported in FCP.

Kona TV is a handy little app that essentially opens up quicktime to be viewed on an external monitor through the Kona card.

wow. I love this application.
So the new Final Cut Pro Studio 2 supports H264 correct?

Not that I know of for editing...no.

It would be news to me if it does. H264 is a web delivery codec in it's current state. It is not optimized for editing.

Panasonic and others are making camera codecs based on h264, but they aren't here yet.

Strange that AJA Kona TV will allow me to open up and play (for instance) a 720p trailer downloaded from the apple website (1280X544, H.264,AAC).

But won't play that same piece simultaneously through HD-SDI to my big monitor.
(I just get green shaky bars and interference).

It's almost like the right format under "display" isn't there? But I've tried them all.

Think of the Kona Tv as a souped up Qucktime app. H264 plays through quicktime on the computer. Since the KOna card cannot understand the H264 codec, it can't play it out to monitor, but since the computer does understand, it will display it on the computer monitor. If H264 was a video editing codec, the KOna could play it.


Does that make sense?

ahhh yeah, that does make sense.
Is there a way to convert h264 to quicktime (after downloading) while still maintaining the quality so I can play it through Kona TV on my big monitor?

You can sure try. Run it through compressor and use the advanced format conversion options. The thing is with those h264s, most of them are at a funky aspect ratio so you might have some stretching/cropping that might look weird once getting it a format that the Kona is happy with.

Yes. You can convert them to another codec, such as DVCPRO-HD. I edit an award show for movie trailers and have done a great deal of this. Most (but not all) of the trailers on Apple's site are in the extremely wide 2.35:1 aspect ratio...however, if you use the letterbox filter in Compressor (or the new padding feature Compressor 3), you can properly letterbox them within a 16:9 frame. Some of the trailers are blown up/cropped to 16:9 already (you can identify them by checking its properties), and appear full frame, others are in the 1.85:1 aspect ratio.

Kona TV only play the QT native files and Kona Codec files, so no Mpeg of any type at all.

UC, DVCPROHD, Animation codec, and Now ProRes all work, but nothing that has a licensing fee as mpeg 2 or mpeg 4 like H.264 do.

One very cool thing that KonaTv does is play out a simultaenous alpha when playing an Apple "None" compressed movie with an alpha channel. An "Animation" movie works too depending on your processor.
