Noisy renders in 6.03
Ever since we upgraded to 6.03, my renders seem to have a lot more noise and compression in them than the unrendered clips. All I an doing is a simple 3-way CC and Broadcast safe. I am using prores422 (not HQ) 1080i, 29.97 with HDCAM footage. My render processing is set to render 10 bit material in high precision YUV, which I haven’t changed from the default. Under render settings, I have filters and frame blending for speed checked, and I am rendering to the sequence codec. The footage looks ok, then as soon as I render, it looks like crap. Any other settings I should check?

what happens if you try 8-bit?
-
I tried 8-bit…didn’t seem to make a difference. Although prores is a 10 bit codec so setting it to 8 bit
seems wrong to me. -
This is very weird. At different points in the same clip, the level of noise changes dramatically.
This is only after rendering. I tried both prores and prores HQ…same results.
Anyone ever see this behavior? -
true, its a 10-bit codec, but with all the weird things
that can happen, stranger things have been suggested that actually work. 🙂have you tried changing the compressor type to pro res hq?
how about removing broadcast safe? any change?
remove 3 way cc but leave broadcast…any change?
the 3 way cc is bad at bringing out detail in shadows and blacks.
you end up with some blue and noise. Colorista an alternative cc
plugin will give you no noise and inky blacks just like the way it should be. maybe try the demo just to see if that helps. -
I did a few more tests. It doesn’t seem to matter what
filter I put on…everything still gets noisy and grainy.
Even if I apply a 3-way CC and don’t change it from the default.
I can watch it render and then POP – as soon as the render finishes it goes grainy.
And it’s not on all the clips in my show…only a few – but everytime I try a render on these clips they turn to crap.
I can step through the clip frame by frame and it seems to change from frame to frame – some frames are noisier than others – maybe because Prores is a VBR codec?
Other clips render ok. I also tried recapturing the clips at uncompressed 10 bit 10800i, and DVCPROHD. Using these codecs, everything is fine…no extra noise on renders. -
this is one of the reasons I don’t use pro res for HD work.
(unexpected issues) -
What do you use? DVCPROHD? Uncompressed?
