exporting clips for submission using 10 bit uncompressed 4:2:2 codec
Hi everybody,
I’m currently working on a submission for a film stock agency. They recommend using either the Blackjack or AJA 10-bit uncompressed 4:2:2 codec for exporting. I’ve downloaded what I can find off both companies’ websites. There is also the Apple 10-bit uncompressed 4:2:2 codec already in Final Cut Express HD, I’m not sure if there’s a difference in quality. I’m not even sure if I got the right codec from AJA or Blackmagic.
When I export the file using “quicktime conversion” and any one of these codecs, and play it back with Quicktime Pro 7, there are tiny lines even with playback set to high quality. I don’t know if this is quicktime pro’s fault or if I’m doing something wrong, so that’s my question. If this is the quicktime player’s fault, am I doing it right? What is the best way to export a quicktime movie using 10 bit uncompressed 4:2:2?
I’m editing on a mac powerbook g4 1.25 ghz, with Final Cut Express HD.
thanks very much,
greg

Sounds like you’re seeing interlacing lines. That’s typical of material displayed on a computer screen that’s designed for display on an interlaced video monitor.
All the best,

Thanks Tom. The lines show up because my laptop has a progressive scan monitor? If I send it in like that they won’t send it back?
One more question: Using either the apple, blackmagic or aja 4:2:2 codec for 9 second clip creates a file of about 300MB at a data rate of about 300mbits/sec. Is this how it should be? I have a lot of clips of lengths ranging from 9 seconds to 1:30, I’ll run out of space fast if they take up so much memory. Because I’m new to all this, can you tell me if I’m doing anything wrong? Is this what my editor will expect?
thanks again,

Talk to them. Ask them what they want. Tell them exactly what you’re delivering.
If you want uncompressed that’s the price you pay for playing with the big dogs.
All the best,

if you need to know ahead of time if you have room to render a file in particular format you should google VideoSpace widget. I believe there are two different widgets out there that do this
