rolling title unstable

Tweening, which is a digital subsitute for animation gels ( when stuff like mickey mouse was drawn by hand and his legs moving were layers of gels ), is tricky. The best for me is to use a sans serif font ( like Arial ) and make the type size bigger than smaller ( use all the real estate of the screen size and don't try to make it really small ).

Different programs ( AE, PPro etc. ) will use different programming to do the tweening.

The frame rates should match and the other stuff ( refresh rates and so on ) but that's obvious for all film stuff. So that's kinda irrelevant in a way. If you watch film ( video) on your iphone or computer or your TV... what you want is to see decent stuff.

Try using a sans serif font ( easier to tween ) and if you have to experiment more, try using a different editor. The tweening progamming is a top secret thing for each company.

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.

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.

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.

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.

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.
