dv timeline to uncompressed = render weirdness
I’ve read about this workflow a bunch on this forum, but this is the first time I’ve tried it. I’ve created my show in a dv timeline (material was shot on sony 570 then brought in firewire), I’ve added all my graphics and completed the program. Next I’ve selected all in the sequence, copied, then pasted to an uncompressed 10-bit timeline. Center position in the 10-bit timeline is 0,1. However when its done rendering I’m getting really weird blockiness around all my graphics. (photoshop files with logos).
When I render it in the DV timeline its fine besides the regular ugly dv stuff. DId I miss a step here? Should I Just take my dv sequence and nest it in the uncompressed timeline?
Thanks for any help.

Jeremy,
The “regular ugly DV stuff” ain’t gonna ever look any better than it is, no matter what you do to it. This workflow works fine, except that 10 bit is way overkill 99% of the time, your graphics will look just fine in 8 bit.
What I always do in this situation is just open up the sequence settings and change the compressor or easy setup to 8 bit, render and off you go. You’ll need a video card or an iO to see the program play over a monitor, but if you’re going to QT or mpeg2 for a DVD you’re good to go.
You can try nesting in an 8 bit sequence if you want, but I always just keep this simple. I usually don’t save the changes, as it’s faster and easier to make any future changes in DV.
HTH…

I understand the the “regular ugly dv stuff” in the video isn’t going to change but the graphics should. If I had a place to post photos of what is happening, I would as they would explain it much better than I think I did.

Here are examples of what I’m talking about. 10 bit timeline – https://www.youtube.com/watch?v=HZB2p_u_M8o dv timeline – https://www.youtube.com/watch?v=zVqstuEXUqI
The weirdness is plan as day even in the crappy web video.

Ooooohhhh. I see what you mean. The DV is at least useable. The 10bit isn’t. It’s green ugly. Bad art. (if there is such a thing) I normally wouldn’t drop the DV sequence into a 10bit timeline.
Do newly built keys and graphics work in your 10bit sequence correctly?Love,

The goofy thing is, its not all the graphics. The lower thirds and wipes all render fine. Its just my bumper graphics and end credits that render goofy. I didn’t create new graphics, but I did reimport the ones already built and I’m having the same issue. They were built in photoshop. I just don’t understand why they work fine in dv and not in uncompressed.

Is your end graphic a series of keys on top of full screen background clip? Or is the whole thing a photoshop sequence of layers (and that’s the way it looks in the imported sequence)?
Sequence settings are set to what for video processing? “Render in 8-bit YUV”, “Render in 10-bit material in high-precison YUV”, or “Render all YUV material in high-precision YUV”?
What happens if you change that setting (copy your sequence first and make the changes in your test copy) and re-render a portion of that end graphic? any differences?
What is your “Process Maximum White as” set for? If you change it what happens?
Again in a test copy of your sequence, what happens if you change your sequence compressor settings to “Uncompressed 8-bit”? Better? worse?just guessing….

Maximum white as white. I changed the sequence to 8-bit uncompressed and the video processing from 10 bit to 8 and it renders clean. Guess I’ll just do it in 8 bit as was mentioned earlier, 10 bit is probably over kill anyway.
So a usable work around is found, but I guess I’ll never know why putting it in a 10 bit sequence doesn’t work. No matter as this TV show only has 4 SD episodes left before joining the rest of the shows we produce in HD land.
Thanks for the help.

I’ve had more than a few quality issues with the 10-bit codec. I don’t think we’ll ever know why it’s not working properly either. I’m glad you’ve found a useable workaround.

I just had a similar problem (funky green blocks just a bit away from the edge of the keyed area) with a chroma key using Apple Uncompressed 10bit 4:2:2. I called Apple Support and we tried to unload QT 7.1.3 in order to install QT 7.1.2, but couldn’t do it. The cure was to change the Sequence Settings/Video Processing/Motion Filtering Quality = “Fast (linear)”. Any other setting produced the green uglies– even in 8 bit render.
