Aliasing after capturing to 10 bit
I think this is a workflow problem.
My sequence is in 10 bit uncompressed because it originated on digibeta and I want to maintain the highest quality.
I got footage on DVCPro50 which I took in via AJA Io as 10 bit uncompressed. However that footage looks like crap – like its unrendered, but it doesn’t require rendering because its now 10 bit uncompressed in a 10 bit uncompressed sequence.
What to do?
Thanks.

It may just be a field order issue, although you didn’t tell us if you are PAL or NTSC or details on your sequence settings, particularly field order. Also how are you monitoring?
What happens if you drop a shift field filter on the DVCPro footage?

I’m in NTSC, monitoring on both an NTSC monitor and an LCD client monitor.
I tried the shift fields – to no effect.

Was the DVCPro50 captured via SDI? I am not familiar with the Io but if it was, then any field order issues should have been sorted with the SDI input.

No, I decided to just go in firewire. Perhaps I should have done SDI.

I would do that and let hardware do the transcode to uncompressed 10 bit. Perhaps do a small test capture and see if that solves the issue

Thanks Michael. Yes, I figured I’d have to re-capture. Basically I just wanted to verify that its okay to do the convert on ingest rather than work in a sequence with multiple codecs. I didn’t want to have to render every time I hit one of the DVCPro50 clips in the sequence.

The best conversion is SDI out of the DVCPro deck so yes, this would be the preferred method. I would still do a short test to make sure it solves all your aliasing issues.

Let me get this straight, you captured dv50 over FireWire as 10bit?
-
Ummm, yeah…

Let me get this further straighter. 🙂
Fw out of the dv50 deck in to 10bit UC?
If that is true, there’s your problem.
