Text flickers on Wirecast 8.3

Telestream Team,

Good afternoon. I just upgraded to Wirecast 8.3, and I'm having a problem with text flickering when I activate multi-layered text shots. I've isolated the problem specifically to Wirecast 8.3 and to the text layers themselves by creating brand new projects and only adding text shots (no other media or video shots connected.) 

As far as I can tell, the problem only appears when you have more than one text shot in a given project. Here was was my procedure: 

1. I created a Wirecast project and added a double-layered text shot. When I activated the shot, no issue. 

2. I did a "Save As." In the new project, I added two other double-layered text shots. I then started encountering the flickering problem. 

3. I did a "Save As" again, creating a third project. I then deleted the two new double-layered text shots, bringing us back to the original double-layered text shot. Even though I was down to just one text shot, I was still getting the flickering when I tried to activate that shot. However . . . 

4. . . . when I saved this third project, and got the "This document contains sources that are not referenced by any shots" pop-up window, and deleted the other text sources within that window, THAT'S when I went back to not having the flickering problem. So it was not just a matter of deleting the shots - it was a matter of deleting the sources. 

I've attached the three Wirecast projects to this ticket, numbered in the order I created them. I also attached a recording generated from the second Wirecast project that shows the flickering. 

The stats for the MacPro (the same one as always) follow:

    So these are the key components it would seem.

    Can you start with a new blank document and repeat your sequence of events and cause it to happen again? Also Reset Wirecast Preferences first as well (Wirecast > Help > Send Support Information but lower left Reset Preferences). Repeatability will help us find the cause. Thanks for providing the detailed steps.

  • Hi Craig. I wondered if the "Save As" part of the process was causing issues, so: 

     

    1. I reset Wirecast's preferences

    2. Created a brand new project. 

    3. Added multiple double-layered text shots to the Wirecast project, and started encountering the problem right away, without the "Save As." 

     

    I tried to control for different fonts, font sizes, text box shapes, text box positions, but the issue was consistent across all of the variables, as you'll see in the attached video. Literally the only thing I had to do to create the problem was to have more than one double-layered text shot on a single Wirecast project.  

     

    I've attached the new Wirecast project to this ticket, along with the video I recorded today. I also tried to attach a report I generated via "Send Support Information" but I'm getting a "File type not supported" error. Any insight appreciated.

     Your document is fine on my system. All two text layers shots are rock solid. Don't flicker in Preview or Life or during transitions. So I suspect the issue is not in the document.

    Let's see if it's specific to the User Account. Create a New User Admin account and log in. Opening only Wirecast, create two layer text shots and see how they behave.

  • Thanks for the reply, Craig, and for the helpful GIF. Three things: 

    1. I should have specified that the problem is not perfectly consistent. Sometimes it happens immediately after creating that second text shot or immediately after re-opening a Wirecast project; at other times, it doesn’t occur until after multiple activations of a shot. I'm not sure how many times, total, that you clicked on any given shot, but this might explain the discrepancy between our results. 

    2. To make sure it wasn't a problem with our MacPro, I installed a demo version of Wirecast 8.3 on a separate computer (a MacBook Pro - specs at the bottom of the e-mail) and was able to easily recreate the problem on that computer. So, not only does  the problem extend beyond a particular user account - it extends across multiple computers. 

    3. Using that laptop, I created a screen recording akin to your GIF, which I attached in MP4 format. As you'll see, the recording begins with me opening Wirecast. I then encounter the problem the very first time I activate that second text shot from the left. The problem persists when I activate the third text shot from the left. After that, we have a period of everything being fine, with none of the shots presenting issues. However, right at the very end, I get the problem on the second text shot again. 

    In addition to the MP4 file, I've attached the Wirecast project used in connection with the screen recording. I hope we can figure this out. Thanks.

  • Micah Bochart Since you mention you're on 10.12.5 please update to the last version of that OS, 10.12.6 and test in a new document. We need to make sure the issue isn't tied to an OS/GPU issue that Apple may have fixed.

    Once you've done that, if you're still seeing the issue. Please report it. Then do a screen recording of not just the issue but the entire process of doing transitions until the issue appears. Granted that may be a long recording but if you follow up with an email with the case number you receive we can give you information to send us the file so we can see how long it takes for the issue to begin.

  • Sorry, I omitted the OS for the MacBookPro laptop. It's 10.13.2 (High Sierra). Thus, it's not OS-related.

  • Micah Bochart Thanks for that. Include that you tested on two computers and their respective OSs.

  • Certainly. I had, in fact, specified that I was testing on a separate computer. I said "To make sure it wasn't a problem with our MacPro, I installed a demo version of Wirecast 8.3 on a separate computer (a MacBook Pro - specs at the bottom of the e-mail) and was able to easily recreate the problem on that computer" etc.  I'd just mistakenly left off the OS for that second computer, which I apologize for.

  • Hi Craig. I hope you're doing well. Sorry if my tone was off in the last post. I really appreciate your time and energy. 

    I just wanted to follow up and see if you could offer any additional insight on this. Thanks!

  • Hello everyone,

    I am having the same problem.  (check the video)

    System:
    - WC 8.3
    - iMac Retina 4k, 21.5-inch 2017
    - OS 10.12.6  
    - 16 GB RAM
    - 3.6 GHz Intel Core i7

    Randomly, when changing from shot to shot, text disappear and when send to live, it start blinking.

    This blinking is not only inside the software, it's also visible through the streamed signal and the one recorded.

    Possible solutions I have tried with no success:

    - Install again fonts and work with local fonts  

    - Instead of duplicating shots, create each one from scratch, so I don't have copied elements or names.

    On solution that work,  is that every time I select a shot, go to the text box of each text element and write a letter, before sending that shot live, but this is not functional at all when working on a real time stream. 


    Regards,

    Felipe

  • Hey guys,

    I am having the same issue with WireCast 8.3. 

    I have only 4 titles and they will randomly disappear when I select one of them. When I go live they begin to flicker back a forth between the preview and live windows. I've found to bring the text back I need to add and delete a letter to the text box. However, this does not guarantee they will remain visible for the duration of my stream. 

    Here are the specs of the iMac I am using:

    Tech support told me to go back to 8.2 with this link.

    I haven't had the problem since I went back.
