    Staying within 100IRE and 7IRE

    dstack1014 Community Member

      I've noticed that if we place Brightness & Contrast on a clip that it seems to help keep the YC levels within 100IRE and 7IRE.  That is until you render it!  Then the levels fall back across the line, especially when it comes to titles made in Premiere! We have a freelancer that uses Premiere Pro CS4 and he has an even tougher time with this, so he's been rendering out his segments in After FX after adjusting levels in AF.  Am I way off to assume that I'm suppose to be able to make the adjustments in Premiere and have the levels remain where I set them after a new movie clip is rendered?

       

      Our company is slowly replacing our NLEs with Final Cut systems, and I'd like to defend Adobe Premiere against FC, but I'm losing this battle.

          Someone suggested I should try Auto Levels. Here's my problem with Auto Levels...

           

          Auto Levels does more damage than good unless it's used on a static shot with nothing moving into or out of the shot that might cause phase shifting.  Even a lower third fading out usually will cause unwanted and DRAMATIC color temperature changes.  Auto Levels is clearly not the answer I'm looking for, but thanks anyway.

           

          A lot of our lower 3rds that are created in Premiere Pro are above 100IRE. I just tried Auto Contrast, and that at least doesn't mess with color temp, but once applied, the YC waveform shows that the problem has been corrected without having to make further adjustments.  Great! But once again, I render the thing out and the IRE boundary has been violated.  Another thing I hate about both Auto Contrast and Auto Levels is that if you have a dip to black in the clip, make sure you have a FRESH dip to black or it'll look like A$$!

           

          I'm clearly disillusioned by Adobe Premiere Pro, and will continue becoming jaded unless someone has a better answer.

            I can only address the Auto Levels part. I have yet to find any use for it. As you point out, unless the shot is static and the lighting stays perfect for the entire shot, it's useless. I use Levels (manual) and Shadow & Highlight (again on manual) for similar work.

             

            With the exception of a very few specific uses in PS, I have yet to find any use for Auto-anything. Luckily, PrPro has the ability to do manual, with either another Effect, or by control in the Effect Control Panel. Poor users of PrElements only have Auto for most of these and no other choice.

             

            Good luck,

              Thanks for your reply.  I'll accept manual adjustments as a partial answer. I guess until Adobe addresses this with some kind of patch, all we can do is use the manually adjustments of Brightness & Contrast.  What remains unresolved is that the IRE levels change AFTER a movie clip has been rendered, so we have to play the game of Over-Correction and hope the dart hits close to the target.  There's something wrong with this!
