This tends to be because of fps and screen refresh rates.

 

For setting a scroll, it's good to have a monitor that you can set for many refresh rates. You want to have the monitor and your sequence running the same fps/refresh, or have the monitor at twice the refresh of the sequence FPS if at all possible.

 

Next ... make sure your scroll moves at whole-pixel increments. To figure this out, set your Timeline to show frames rather than timecode. Note how many frames it takes the roll to run. As you really want numbers that are easy to divide in whole-integer numbering, changing the length of the graphic to get a number of frames that would be divisible by 3, 4, and 5 is a good idea.

 

Next, check the ECP for position (vertical) of the scroll, the beginning subtracted from the end. This gets you how many pixels of motion you have.

 

Now divide the number of vertical pixel change by the number of frames. You need to get a whole-number, no fractions here. So again, work with both the total pixels of vertical motion or length of the graphic to adjust to get a whole-number result.

 

If you have a crawl with 10,000 pixels vertical motion, at say 5 pixels per frame change, that would be 10,000 divided by 5 for a result of 2,000. Set your crawl run-length for 2,000 frames.

 

This is an example ... depending on the size of your text and length of the lines per line, you may need to move from 4 pixels vertical motion per frame to 8. Whatever looks good to you.

hello need some clarifications

 

first about the monitor: even if i adapt the refresh rate of my monitor to my sequence, that will be for my monitor. What happen when the video will be played in other monitors or tv?

 

then the count

my timeline now is showing the frame, on the ruler when the playhead reach 24 go the next second

lets say at start..1:00:00..then it reach 1:00:24 and then 1:01:00

is that correct? if so i can read the lenght of my rolling clip, and it is 52:20

so as fps is fps, i will have 52x25+20 frames. It is 1300 frames and if i divide it by 5 i will have an integer

Is that correct?

 

the other thing i don t get it

what is ECP?you saying i should calcultae  end of titleclip - start of titleclip right?

but don t understand where to get these values form

 

thanks for help

ok i see ECP isw the effect control panel.

If i go there and i check the varius parameter, i think you mean POSITION, the number is the same bith at the beginning and the end, 960x540. don t see other change in the value

When you have your timeline panel set for frames, it doesn't show 00:00:00, is just shows a number ... like 24680. Which makes it easy to do your calculations.

yikes.  Neil, this is a great post but gotta say I usually just play with the speed in small incremeents til it looks ok and sometimes add a little bit of vertical motion blur.   I guess it all depends on how crazy you want to get (and for me, usually that's pretty crazy).    I can remember people recommending adding a little bit of noise.  Never helped as far as I could see.

 

And I usually find that I can do a better job of laying out the scroll in photoshop rather than in Premiere.   But that may be because I've never had the time and/or focus to dig in to the text formatting options in Premiere.

That has been the general advice if you cannot get a descent scroll in Premiere is to make the text in Ps and animate in Premiere.

 

I never had any issues with scrolls in Pr.: fiddle with the settings until I get it how I want it.

this is not a premiere issue, it's the nature of the beast.  Making smooth vertically scrolling text is difficult in every program as far as I know.  And certain fonts may be better than others...  I find laying out text easier in photoshop, but that may just be me.  There is a service that will make a smooth title sequence for you but when I tried to use them, I found their templates difficult to customize the way I needed...  I don't remember the name of the company, but do some googling or post back and I'll try and remember...

This practice is from Jarle, and after you've done it once, it's a heck of a lot faster than fiddling with settings until it 'looks' ok.

 

You need to have full-frame pixel movement as if there's partial-frame pixel movement vertically it must jump up or down a bit.

 

So ... check veritical position movement figure in the ECP to see what the number is.  Fast to do, simply grab the right-sided scroll bar and slide top to bottom or the CTI and move from beginning to end. You can add a few pixels of movement at either end to get a number easily divisible by 3,4, or 5 quickly.

 

Now divide the vertical movement by say 4, and set the length of the total crawl equal to that number by the Frame count in the timeline. Check to see if the movement is readable. Adjust to say 3 pixels/frame if too fast, 5 pixels/frame if too slow.

I'd be happy if I never had to do another one of these again, but this thread is getting bookmarked.  Now it'll be interesting to see if I can remember where the bookmark is when the need arises.  at least we don't have to deal with interlacing issues anymore

sorry i can t understand ho to check this vertical pixel

i have a text part on my timeline on i can see it on my program monitor

i click on it the part an i can check the details in the ecp

i see the values of the position in the ecp and they are at the default 960 540

Now you says to scroll the bar, i scroll right blu bar of th eprogram monitor and see the text box going up and down

but the values of position in the ecp never change

what am i doing wrong?

The Cool Stuff in Premiere Pro by Jarle Leirpoll.

 

Avialable most easily in ebook/pdf, but also in some places by paper book. Massive book ... detailed.

Here's the settup. Note the Graphics section at the top of the ECP ... and that I'm on the Text section, the vertical position for that.

 

And that I'd right-clicked on the timeline Timecode window, and selected Frames to show the time.

 

So this crawl starts at 1600 for vertical position, and on frame 840.

ok withgh the number of frame i was fine already(now i could switch to frame and the value is the sam ei calculated before)

now vertical pixels:

i see you are not using the "roll" feature of the sw, but you animate the text yourself right?

you says that your vertical position is 1600 but for what i understand i see you have 952,4 as starting vetical position, right?

that is just when the title start to crawl is it?

than i have to move the title to the top until it disappear,and there i would find be the vertical position of the ending point 

is all these correct till now?

The first number is the vertical posistion ... so the vertical position of the text in my image is at pixel1600, and as there are 1080 vertical pixels on this sequence, that means it is down below the viewable area.

 

And yes, I'm setting the settings for the roll manually.

 

Also correct ... move the CTI so the timeline is off the top. You can fudge how far off a few pixels to get an easy to divide number that will result in whole-number results. You want say a 25,800 vertical pixel scroll that divides by 4 with a result of 6,450 pixels for example. This would be at 4 vertical pixel per frame movement.

 

This number is also divisible by 5, so you could have it go a bit faster by setting the frame length to 5,160 frames.

 

And that total vertical movement of 25,800 is also divisible by 6 so you could even speed it a bit more.

 

Whatever vertical pixel you set, you need something that can be divided with a whole-number result to determine frames. 25,800 divided by 7 gets 3,685.7142 ... you don't want a fractional number like that.

 

Of course the other issues determining readability and choice of scroll speed are font size and spacing between lines.

there is something i can't get

 here is my example

first image at the beginning of the scroll (i make some text visible at the bottom for better understanding)

In POSITION have these values

x:1070 y:1080

 

second image is at the end of the scroll (sill left some text visibile)

in POSITION i have

x:1070 y: -1560

Untitled-1.jpg

 

The y change, that is for me the vertical

Why you say that vertical is the first number?

 

so if this would be correct i should calculate the number of pixels used by adding the two y  1080 and -1560

there is  minus though...2640 would be the result?

I wonder if we are talking about rolling titles, or rolling credits. I guess it don't matter.

If it's this hard to make credits and titles, you're using the wrong program to do it.

Make your own, with a program that works without being a nuclear scientist or brain surgeon, or mathematical genius.

 

photoshop with scale position works fine.

cast,crew ecc

and now i think i know why i did not understand the position value of Neil, may be he is talking about the horizontal scroll while i am talking about the vertical one...

Yes, I need to correct something ... you're right of course, it's the second position number that is vertical pixel movement. My apologies.

 

And something odd ... when I did this on my laptop, as I expected, I could click the Roll option in the EGP and then when I wanted to change things manually, go to the ECP and the numbers for the movement showed.

 

But when I did this on my desktop, if the Roll option was checked, the position numbers in the ECP didn't change. Same number-dot-number versions of Premiere, what the ... ? Puzzling.

 

Which is what you're showing in your last post images.

 

So ... uncheck the Roll option in the EGP.

  • Create the roll text, in the EGP or copied to it. This creates a graphic clip on the sequence.
  • Slide it sidewise on the sequence to get a nice even number frame number for the following math.
  • go to the beginning of the crawl clip, use the second position number for the Text in the ECP to place the text just below visibility in the program monitor.
  • Note down the vertical position pixel number and the frame count number also.
  • Click the Stopwatch icon in the Text position line.
  • Set the CTI to the end of the clip, and use the ECP position numbers for the text to move it just out of sight above the program monitor.
  • Click the 'add keyframe' icon for the Text position.
  • Note down the second position number for vertical pixels.
  • Add the two numbers for pixel location together, forget the minus sign ... so say 2220 and -1100, just add 2220 and ll00 to get 3320 pixels of movement.
  • Pick a number like 6, 7, or 8 ... and divide the (in this example) 3320 pixels of vertical movement by that number. 3320 divides cleanly by 8, at 415 frames. Let's try that.
  • Use up-arrow key to set CTI to first frame of the clip. Click in the Frames counter, and tap " +415 ", and it will move the CTI 415 frames further down the sequence.
  • To 'snap' the clip to 415 frames though, you need to move the CTI one more frame, so tap the right-arrow key once.
  • Now click the end of the graphics clip, move it to snap to the CTI, and you have a 415 frame clip.
  • drag the second keyframe in the ECP text position line to the end of the clip.

 

You now have a smooth scroll at 8 vertical pixels/frame.

 

This sounds a lot more complicated than it actually is ... do it two-three times one right after the other to start to get it down, and it's really pretty quick. I had as much trouble thinking about writing this out simply because I don't have to think about it anymore. Weird as that sounds.

 

And it really takes only a minute or two when you get it down, and does give smooth scrolls.

 

Neil

ok the procedure now it is clear, or tat least seems to me

I don't see really differences from the credits i did ti using the roll option without all this calculation though

I can't see that with this procedure text is perfectly stable and smooth, it is just like the text i did without this procedure

And also with pohotoshop, i tried create jpg with text inside, still some lillte tremblin

For what i have seen all the 3 methods have really very similar results and none of them is perfect

At that point, what you are seeing is undoubtedly the problem of the refresh rate of your monitor. Professional broadcast quality monitors allow a wide range of refresh rates, timed for the 'typical' fps rates expected in video post processing work. Some computer monitors, like my BenQ PD2720U, also allow a selection of those framerates.

 

So I can set my monitor to the fps of my sequence.

 

Most computer monitors have only perhaps two refresh rates available, and if they don't match or aren't a multiple of the fps of the sequence, you can and probably will get some visisble stutter of moving text lines.
