Caption Aliasing
Hi all,
I've now split my caption bugs into two reports. This is about the horrible edges around caption text.
Just as the title suggests, the captions have jagged, aliased edges, as opposed to smooth crisp edges. I don't get the same results when using the standard type tool, or importing PNG files, etc. This is something specially reserved for captions.
Please note that these issues occur on both Mac and PC, but I'm currently on a Windows system, so I will post the specs for this machine:
Premiere Pro 13.1.2, build 9
Windows 10 64-bit (1903)
Intel i9-9900X
64GB RAM
Nvidia RTX 2070 (431.36)
2x HP Z27 displays (3840x2160 @60Hz)
Any thoughts or ideas, please fire them through. If you require any further information, please don't hesitate to ask, and I will provide it as soon as possible.
Cheers,
Darren

We have completely redesigned the captioning workflow in Premiere Pro version 15.0. You will see many dramatic workflow improvements. Please update to the latest version.

i'm having the same aliasing/rendering issues described by darren. editor colleagues also face this issue on an almost daily basis. interesting that this hasn't been fixed, as this issue was posted almost a year ago now.

This is a known issue and in the design queue. You can work around this by starting with a larger type size and modifying the object size.

Hello Darren,
First off, sorry you are having a less than enjoyable experience with Open Captions. At the time Open Captions were implemented it was to support single stream film subtitling. As you probably know, open captions have become a much more stream intensive (mostly for social media and translations), long story short, this issue is known to us and in need of some redesign.
Thanks for the feedback, though, getting customers to describe their frustration makes it easier to convince people captions need more work.
The workaround for when you get into this state is to copy and paste the timeline into a new matching project then re-add the caption track.
Yes, super annoying and yes we need to fix it, but hopefully this will get you out of the woods on this project.
Cheers,
Nate
PS - the rendering for Open Captions is rough as well. The workaround is to create at a larger font size, select all captions and make them smaller, the edges render better.
If you have more questions, email me at mcfadden@adobe.com.

Happens to quite a number of users. Captions, both open & closed, need attention.

Hi all,
So, here's a bug report for captions not updating, and horrible aliasing around character edges.
1) Captions don't update
This isn't something that happens every time, but it happens almost every time. Basically, captions don't update.
This might be when changing font details, like type, size, colour, etc, but also when changing the content of the caption, or its timing, or its placement. So, the problems are kind of across the board.
It should be noted that I'm referring to Open Captions, with a sequence appropriate frame rate, and resolution. This applies to imported .SRT files, and captions created directly within Premiere.
Sometimes restarting Premiere fixes the problem, but not always. When that doesn't work, sometimes I can temporarily modify the captions properties (change the frame rate, and then immediately change it back), and that occasionally forces the captions to be read correctly. Sometimes nothing really seems to work.
What's super-frustrating is that I can see in an expanded timeline video track that the caption has been updated, but in the Program/Source monitor, it shows an out of date version.
Deleting render files, and clearing the media cache does not always resolve the issue. Regardless, having to do that every time I have to work with captions would be a pretty frustrating workaround.
2) Aliasing around character edges
Just as the title suggests, the captions have jagged, aliased edges, as opposed to smooth crisp edges. I don't get the same results when using the standard type tool, or importing PNG files, etc. This is something specially reserved for captions.
