Good day.
We are facing this problem after your last update.
Previously, three channels were launched without problems. And now we are getting a loss of frames. You can watch the video for yourself.
-
Ilqar Please confirm you have updated to Wirecast 14.2.1.
It looks like you have having a problem with low frame rate in Playlist.
What version were you one when this last worked?
Please create a New Blank Document and import just one file. Do not create a Playlist. Play the file back in the Live area and see what it looks like.
-
-
Yes, we have the latest version of the program.
Unfortunately, the problem was solved only by restarting the server and restarting all playlists.
We even tried to completely close and restart the program, but this did not help either.
There were no such problems before the update. -

-
WELL this can't go on forever. It would be logical for you to check the update file or release a patch.
-
Ilqar Sorry but I'm not sure what update file you're referring to. I don't see any other user reports that match yours. Since you mentioned restarting fixed the issue it may have been with the document or the computer's resources needed for the number of files in your playlist.
I previously recommended you test with a New Blank Document and one file. In order to troubleshoot you'd should follow our instructions since we have no reports of this for us to test otherwise. I'd like to help but you have to follow our instructions.

Hello. How I can download 14.0 version Wirecast.
Because we cant work with Wirecast latest version. So many error so many freeze. We need back to Wirecast 14.0-
Ilqar at this link under Previous Versions but I don't think that will fix the issue since there have been no major changes to Playlist.
-
-
Regardless of the changes, these friezes occur. We just got tired of restarting the server every time. There were no such problems on the previous version of Wirecast. If we were, we would immediately write to you about them. After the update, friezes began to appear.
-
Ilqar if you see the issue in the earlier version of 14 you install then it does mean something else changed.
-
-
You misunderstood. There are no problems with the old version, or rather 14.0. Problems came out with the version update to 14.2.1
-
Ilqar rolling back to 14.0 fixes the issue. You've confirmed this?
You may want to test 14.3 Beta to see if that fixes the issue as well.
-
-
Not yet confirmed. We will check the work of version 14.0 at the end of the week.
-
We have installed version 14.0 and will be testing to verify. If there are no problems, we will conclude that they were due to the update. And until a patch is released that fixes this bug, we will not update to the new version.
-
Ilqar It's possible that the newer version of Wirecast may be having issues with some codecs.
Can you list the codec types/containers you are using and possibly how many of each? -
Ilqar The developers would like one of your source files so we can test on our system.
-
CraigS
Hello.
We have been using files with this codecs for several years at Wirecast. By the way, with version 14.0 there were no longer those freezes and frame loss. -
Ilqar Thanks for confirmation on 14.0.
The developers would like one of your longer files to test with. -
CraigS
All of our files are over 1 GB in size. Let me think about where we can drop the file to download. Unsubscribe as soon as I do.
-
Ilqar We can handle large files.
-
CraigS Ok soon i wll send you link WeTransfer and you can download there some our files
-
Ilqar Thanks for that. The developers will use for testing.
-
CraigS
Hello. I want to note that we have been using the old version of the program for a long time. And it works just perfect. How are your tests going?
-
Ilqar We've been testing 14.2.1 and can't duplicate the issue. We don't have other reports of this yet either.
How long does it take for the issue to show?
-
CraigS
Sorry for the late reply. I did not receive a letter stating that you answered. Yes, literally after a while. Maybe even right after compiling a playlist.
I also want to point out one more problem. This problem exists in all versions. Both old and new.
As you can see, the duration of the file in the folder is indicated. But when I add the file to Wirecast for some reason, the duration is drastically reduced. This happens with these specified files. We tried on different playlists, tried to add the file again. The same problem.
-
-
Ilqar said:
we will conclude that they were due to the update.And that will give us important information to investigate.
If you now see the issue in 14.0x it may mean there's another issue.
There was also 14.1.1 between 14.0 and 14.2.1 which might be worth checking depending on your 14.0x results.
Investigation issue WIRE-19018-
CraigS
The problem with the loss of frames was in that version as well. 14.1.1

Ilqar said:
es, literally after a while. Maybe even right after compiling a playlist.So far we can't reproduce the issue with the material you provided. In our tests, it's never right after compiling a playlist though.
No other users have reported this. You need to give us an amount of time we should test for.-
CraigS
Test well.
We are still using the old version of Wirecast

Ilqar said:
We tried on different playlists, tried to add the file again. The same problem.In the Playlist select the file and Modify Duration.
-
CraigS
You offer me this solution. OK. I know about this feature. I'm wondering why this is happening. Is this a software bug or what? Will you test this too?
-
-
Ilqar said:
Is this a software bug or what?We're not seeing this issue either. Perhaps there's an issue with the metadata of some of your files. In order to test we need a file that shows this issue.
-
CraigS
I sent you in the link those files in which this problem was. Please test it. 4 files were. Each link contains two files.
-
Ilqar We tested the files you sent us. We tested several times and always get full frame rate in 14.2.1.
-
CraigS
No no. Check the problem was with the duration with these files.
-
CraigS
I sent you files that Wirecast cut their duration.
You offered me to select a file and select Modify Duration.I tested this point and this is what it led to:
If the length of the file is 20 minutes and Wirecast cuts it for some reason to 3-4 minutes. We used the Modify Duration function and increased the file duration to 20 minutes. But Wirecast gave us the fact that the file plays for 3-4 minutes, as long as it cut it and continues to broadcast this file until 20 minutes are typed. That is, the file is practically on repeat.
Did you understand me?
-
Ilqar We will test to see how Wirecast handles the duration
-
Ilqar All four files show their full 20-minute duration when I add them to a Playlist. Wirecast 14.2.1.
-
Ilqar But when I finish creating the playlist the duration then changes.
We will investigate. WIRE-19172
Telestream Switch reports the shortened durations. I think there's another metadata issue with the files.
-
CraigS
That is, the problem is still in the file itself?
-
Ilqar We are going to check the files to make a determination. Our Quality Control and Analysis Player does point to the file metadata though. We also check our player itself to make sure it's making an accurate determination.
-
CraigS
Well, we'll wait
-
Ilqar There is an issue with the file metadata but we have a fix on our end that will allow the file to play to its full duration. I can't say when we will have the fix ready but it's something we're going to work on.
-
CraigS
Excellent! Do you have many testers in the company there?
-
Ilqar It may depend on how you define "testers" but Telestream is a company with many divisions and file playback development encompass an engine and variants for several products.This is why we test Telestream Wirecast file playback with Telestream Switch which is a Quality Control tool used for individual file testing with Telestream's Enterprise products as well. If there are encoding issues with some of your files you can look at our Telestream Transform or for larger facilities Telestream Vantage. On the enterprise steaming side there's Telestream Lightspeed Live Stream

The problem with the loss of frames was in that version as well. 14.1.1We need to know how to test for it. We don't see the issue. No other users are reporting it and we have many playlist users so we need very specific instructions from you. Using the files you sent us we good full frame rate on every single test with 14.2.1. So we need instructions.
-
CraigS
Ok we'll check again. And we will write to you. Let's explore how to identify this problem.
-
Ilqar said:
Ok we'll check again. And we will write to you. Let's explore how to identify this problem.It's possible the issue requires using a very large number of files or letting the playlist run a long time. But we need to know that to test those specific workflows.
If we test with those four files only for only a few minutes they all play full frame rate. -
CraigS
Well, my colleagues and I will think about it. But I think that we are generally using the old version. This is not a problem. We don't break any rules.
-
-
Please check these files.
They are encoded simultaneously in the same format. But for some reason Wirecast accepts some files in the playlist, while others do not. I gave you a couple of workers and two non-working files.
https://we.tl/t-lixyGnHUsw
https://we.tl/t-Rk5JEJiZ4q-
Ilqar Will check these for duration issues.
-
Ilqar Two of the four files can't be imported at all on Wirecast 14.2.1 Windows 10. We will investigate. WIRE-19151
-
CraigS
I therefore sent you these files. Like the same encoding. I sent you 2 files as an example. We have several of them.
-
Ilqar We are finding out the cause.
-
Ilqar
the video that opens in Wirecast, because it meets all of the MediaFoundation requirements. For example, you can see in the Video tab of the Switch inspector that the AVC profile is "High":
However, the video not importing is missing the AVC profile information. The AVC profile value embedded in the file is zero, which is not a valid profile. This file has the same problem for the AVC level. You can also see that in the Switch inspector:
As a workaround, the user could rewrap the file with another app that properly embeds the profile information.
Analysis using the professional medial analysis tool Telestream Switch -
CraigS
Good! My colleagues and I will study this problem, or replace the files. In any case, thanks for the work done.
-
Ilqar You're welcome of course.

CraigS OK

CraigS
We yesterday
installed the most recent version of Wirecast. We will test. While the program is stable, no problems. She began to work faster.There is one problem where Wirecast freezes and eventually collapses. This was also the case in previous versions.
At the end of each week we remove unnecessary files using the "Media - Show Asset Manager".
With the broadcast turned off, we tried to delete several files, say 20-30. The program froze, eventually closed. We tried to delete 5-10 files, Wirecast hung again, but did not close. After a while, let's say 2-3 minutes, it would be possible to continue working. But if you delete all files at once by selecting the "Delete All" button, then Wirecast does not hang at all, but simply deletes everything and continues to work normally. Can you check it out?
-
-
Good afternoon, Please add functionality so that you can scroll the playlist up and down. I am unable to view the files that have been added. Since the playlist does not fit into the screen.
-
Ilqar Yes large playlists are difficult to access shots not being displayed. Investigating the feature request. WIRE-19390
-
Ilqar We believe it's a bug because it's reported to happen only to previously saved documents. In new documents, there's a scroll bar. We'll work on fixing this.
-
CraigS
Ok, we'll wait for the update. But I'll tell you, we've installed the latest update. And with him, unfortunately, the third channel (Ie the third playlist) could not start. The program was hanging. Although before that we launched three channels. So far, back to the old version 14.0
-
Ilqar We continue to work on playlist issues.

We find resizing the window will 'redraw' the shots, and then you will be able to scroll to the last row of shots.
Does resizing his window enable you to regain scroll-control?-
CraigS
Can you demonstrate what you described clearly on the video? Please.
-
Ilqar
See our testing which shows when can't and then can get the scroll bar.
-
CraigS
Good. I understood you. By the way, the program works very cool for you. Probably the performance of the Mac!))
-
Ilqar Although we still need to fix it can you get the scroll bar after resizing in the video.
The new Macs are very powerful. When the updated Apple Silicon chips come out they will be even more impressive.

It's possible that maybe there's a memory lead so perhaps monitor memory when deleting assets.
The number and size of files may be a factor for example.-
CraigS
YES files are big. The file size changes from at least 2GB to 6GB. And there are many of them.
I’m just wondering why Wirecast doesn’t hang when deleting all files at once, and if you delete 10-20 files several times, it freezes and turns off. Essentially it should shutdown when deleting at a time too.
-
Ilqar We've seen a similar issue where Wirecast hangs when deleting a lot of large files causing a hang. We are already working on the fix but it'll be a bit before it's released. Investigating WIRE-19571
