HD credits on SD TV

	HD credits on SD TV by Karen Gall on Nov 17, 2009 at 11:45:21 pm Has anyone noticed 'jittery' HD credits over motion graphics if viewed on SD TV...or is this definitely still a field reversal issue? Thx Respond to this post   •   Return to posts index

	Re: HD credits on SD TV by Jeremy Belzer-Adams on Nov 18, 2009 at 1:23:48 am We use static cards for all of our broadcast credits these days, anything else ends up looking crappy when down converted. Respond to this post   •   Return to posts index

	Re: HD credits on SD TV by Aaron Neitz on Nov 18, 2009 at 1:53:41 am What format of HD are you working in? How are you creating your downconversion? There are a variety of things that could be happening. Need more input! Respond to this post   •   Return to posts index

	Re: HD credits on SD TV by Karen Gall on Nov 18, 2009 at 1:57:20 am Hey, It is a general question. The job was actually cut on AVID & has already been broadcast but what I'm wanting to know is that is it possible it is just the way HD is displayed on SD TV or is it likely be a field reversal issue? The credits are rolling over motion 2D graphics... Respond to this post   •   Return to posts index

	Re: HD credits on SD TV by David Heidelberger on Nov 18, 2009 at 2:40:15 am After years of calculating roll speeds that were an even number of pixels per frame and still having the credits look jittery on both crossconverts (720p to 1080i) and downconverts, I've finally started taking my credit rolls (usually tall TIFF files) and animating them in After Effects with motion blur. Looks much better, I don't need to think about the speed of the animation, and it renders a lot faster, too. - David Respond to this post   •   Return to posts index

	Re: HD credits on SD TV by Karen Gall on Nov 18, 2009 at 2:55:03 am Great tks...not a bad idea. I just thought of applying a shift fields filter or deinterlacing the graphics etc. Respond to this post   •   Return to posts index

	Re: HD credits on SD TV by Dean Sensui on Nov 18, 2009 at 10:20:44 am From my limited experience, any element in the credit roll should take at least 7 seconds from the bottom to top of the screen. Somewhat similar to the "non-stuttering-pan" rule/recommendation/suggestion. By the way, ever wonder why credits don't roll -down- the screen?

	Re: HD credits on SD TV by Mark Raudonis on Nov 18, 2009 at 3:42:58 pm Despite everyone's efforts to create the best looking credits, all that work is often in vain. Networks can and do employ "time compression" boxes which will totally trash anyone's careful calculations for "best speed" crawls. This is most typically done for syndication runs where they're trying to squeeze in more commercial time. Then there's the "no credit" policy that some cable networks have elected. You can't win!
