Video File locks up WC

So in V7 and 8, we have had WC lock up when selecting a video file.  This has happened on multiple, otherwise stable machines. And no rhyme or reason. In testing it will work fine, and in live production, it will lock up and demand a restart!

 

Could it be the file type, codec, or wrapper?  These have been standard .mp4's 

What would be the ideal file type and setting to encode our video file to?

     As .mp4 is a container the source and codec may be a factor. It can be codec or GOP structure. The specs of the computer can also impact the ability to playback certain files. 7th or 8th generation Quad i7 processors may be the best for example. If the CPU% reaches and passes 80% there can be problems as well.

    The idea files would be "I Frame" type files such as Apple ProRes on Mac or MJPEG on Windows. Some H.264 mp4 files are easier to handle than others.

    I'd like to help so if you can provide your system specs, CPU% at the time of the issue and source of the files, I can analyze and see how we can help.

  • William Bacon : It seems, we are encountering the same issues with WC 7 / WC8.
    I also opened a support thread: https://telestreamforum.forumbee.com/t/36fadk/wirecast-8-gui-freezing

  • My opinion is that Windows 10 does not play nice with the latest versions.  V7 and V8 both had issues with crashing.  I reverted back to V6.07 and found stable performance again.

    Also: Chroma key in V8 was weird, I would use the mouse to pick a color and nothing would happen, until I restated WC then the key would be applied.

  • William Bacon again I'd like to help buy you have to provide specifics as it's hard to troubleshoot general statements. If you have an issue with Chroma Key you should post that separately.

  • William Bacon Although mentioned the issue with Wirecast 8. That's what we'd troubleshoot.

  • CraigS as I mentioned I reverted back to V6.07 till I can find a fix.

  • William Bacon Have you submitted the crash log and received a case number? The engineers need to analyze your system and the crash determine how to fix.

    As you might know, we provided a lot of crash dumps and additional information to help your support fixing the issues.

    Unfortunately we also had to revert to Version 6 and will have difficulties to perform additional tests with Version 8.

    Because some users reported that kind of issues with Version 7+8 on Windows 10 in different environments at stable machines, your support should be able to set up an own test environment and discover the reasons for GUI freezes/crashing of Wirecast.

    As we mentioned: We would like to help, but we are needing urgently our stable production PC for streaming live events. Users should not be beta testers.

    When we will find some time, we will back up our machine and install Version 8 for further testing.

    Would you be so kind and ask your developers for setting up an own test machine. Theay should easyly run into issues by using video files.

  • Michael Becker Providing the crash dumps is most appreciated. You can follow up with the case number you were sent to ask for a progress report.

    It's quite possible that the issue is confined to certain configs so the issue may not be as obvious on our test systems.

  • We had three successful live streams this weekend on 8.1 to both YouTube and Facebook. Problems solved with the latest version.

     hey Craig, i've been long experiencing glitches when switching from one video shot to another (within the same layer), or overlaying a 2nd video shot over another, or even when overlaying a USB camera on top of a video shot in progress. The glitches are there almost 100% of the time (and yes, including on WC 8.1), and range from something forgivable, like 50 milliseconds(?) to sometimes 2 whole seconds of stuttering, latency, distortion (not use-able).  

    The computer is the MacBook Pro 3.1ghz i7 16GB 2TB SSD 4GB graphics (top of the line), and the CPU is usually barely tapped; so i don't think the computer would be the problem.  As for the type of video files, I'm hoping therein lies a fix!   Most videos are either iPhone 7 1080p H264 clips, straight from the phone download, or similar clips imported into Final Cut X, mixed with others, and under output at same 1080p or sometimes 720p format, under Apple's default H264.  

    You mention that some H264s are better than others.  I'd like to keep my drive space consumption under control, if possible, so if you could please elaborate upon a few codec options, from smallest file size (some useable H264 settings?), to largest (assuming Pro Res.. with what particular settings?), i'd surely appreciate it.  I have a show to stream tomorrow, and hope to have enough time to transcode soon; Thanks much!  Greg

     You could try Apple ProRes LT. Maybe even ProRes Proxy but examine the quality first. 

    For H.264 use Main or even Baseline Profile instead of High. For Entropy use CAVLC instead of CABAC. These tend to be the easiest to decode.
