Kona LHe HD > SD Downconvert without output?

[John Ladle]

i wish so too, but no, there is not.

Hi,

The 10-bit hardware-based down-converter on the KONA LHe (and the KONA 3) are available on the ingest side, during digitizing, and on output. It can also be used in “E-to-E” Input Passthrough mode, whereas you don’t need to digitize at all, but rather simply pass a signal through the card.

The down-converter will not work file-to-file within the system…that would be a software feature.

Thank you,

That would be my suggestion to doing what you want to accomplish, the SD downconvert for your edit.

But since I can preview stuff from HD in SD, the frame-buffer on the card must be getting this down-scaled image, or? If the framebuffer can old the image, couldn’t it just pass this out this data to an image-sequence or QT file onto disk or to RAM?

Also, wouldn’t it be possible to use the scaler to do a SD anamorphic to SD Letterbox? Above would rock mine (and others) world I reckon. The hardware downscale of the Kona LHe beats even a 100 000 dollar DS or Inferno system.

I guess we’ll have to get a dual-system setup for the down-rezing until we have our own digibeta-deck.

[Erik Lindahl]

Downscale on capture isn’t an option for many of our productions. They are filmed on film, colorized and sent to HDCAM SR and then ingested as a 4:2:2 10-bit UC file. Going out to something lesser than HDCAM SR would be sad and both HDCAM SR and HDCAM decks are really expencive to rent or buy. We just want to deliver an SD copy for TV with the best conversion possible and so far the Kona LHe is outstanding. But since we have to output the SD-converted signal somewhere we’re in though-luck-land since we currently only have one suite and no decks. File to file based transcode would mean a great deal for studios not having a large amount of machines or decks. It would be extremely cost effective, even if you couldn’t transcode at realtime speed (FCP took a good 9 minutes for 20s of HD material to transcode to SD with much worse quality than the Kona LHe offers).

Get a used dual proc mirror-door G4 and the Kona LS and you have a injest station for your downconverted SD materials from the Kona LHe. Definitely cheaper than a DigiBeta if recording is your main purpose.

Yeah, we have a G5 with a Kona LS actually but it was “going out the door” to become a sound suite. One-station solutions are always nice to have
