Premiere Pro, Roll credits flickering/jerky

Hello, I am currently working on a movie for two years and finished working on the end credits. 

I realised the essential graphics roll credits is making my text laggy and jerky. How do I stop this issue?

I am using 23.976.

How do I reduce the lag? I've tried reduce-interlace-flicker and added 1.2, and make the text alittle grey to all the text. It is still showing the same issue.

Meant to say the problem is the jerkyness of the scrolling.


First, if your monitor isn't refreshing at either the same frequency as your sequence or double it, that can cause this. Which is why it's good to have a monitor that comes with refresh rate settings to match video work.

 

Second, IF the monitor is showing them correctly without visual jerkiness, you need to have whole-number vertical movement per frame.

 

Set your timeline timecode to Frames. Then count the length of time in frames that you want to have for your crawl.

 

Now you need to do a bit of math. Your vertical motion needs to be a multiple of the 'horizontal' motion ... the frame count. In even "whole" numbers.

 

So you have a vertical scroll ready ... and it's say 9,000 pixels total 'height'. You want a typical 3 pixels per frame movement ... so you need to set the length of that scroll on the timeline to 3,000 frames.

 

But if you want a slightly slower 2 pixels per frame vertical movement, then ... you need to adjust the 'length' or frame-count of the crawl to 4,500 pixels. Because you need an exact number of pixels in whole numbers.

 

If you can't divide your pixel height of your crawl by the speed in frames of movement, then you need to make small adjustments to your crawl to get that so that you have a whole number pixel count.

A "crawl", vertical movement for text in the end credits, is very difficult. First, you have to have the perfect timing of motion. Which is to say, no "partial" frame motion. For every frame to frame time, there must be an exact 1, 2, or at most 3 pixels of vertical motion.

 

If you divide the number of frames of the crawl by the vetical frames motion and get anything other than 1, 2, or 3 ... say you get 1.2 ... that's a problem. You need to adjust the length of time until you get exactly a full integer number, no decimal points.

Oh, do you mean by dividing the crawl motion to get a whole number instead? How can I find the number of frames of the crawl?

That is still the most excellent and necessary book for professional editing at speed using PrPro out there. I'm on my ... 3rd? .. 4th? ... read through. I've got that book in physical paperback form, all like eight pounds of it, AND ebook on my tablet.

 

I had the ebook, and had read that whole thing already. Used it by my computer every day. Then at Adobe MAX 2018, going through the MAX 'bookstore', I saw a printed copy on the shelf. I didn't even look for the cost, I just grabbed it and went to the checkout stand. I'd have gladly paid whatever they asked.

 

It's that good. And I do prefer the paper copy for sitting and simply reading through.

 

It's got a massive, two-pass Table of Contents at the beginning ... a general TOC, then one listing sub-sub topics throughout each chapter. And a major Index at the back. So finding what you want is normally pretty easy.

 

And it covers setup of Pr, general tips, audio setup & corrections, advanced editing/trim techniques, color, graphics work (including examples of planning a graphic), compositing in Ae for Premiere work, and more. In stunning depth and breadth.

Great review. I have both also, though I haven't actually used the paper copy. I broke out set of 13 pdfs to use on my phone, as Acrobat reader does (did) not work in Liquid mode on > 100 pages. So, I've been reading more of it now, and I must admit having the audio at front was interesting, but I was glad to get to the video stuff. 

 

I wish there was an indepth look at Productions. I just checked out yesterday the 3 links you left for someone. I have a question about 'reuseability' I keep reading about in productions. I'll post it on a new thread.

This is for After Effects, but it may apply to Premiere Pro:
