How can I get rid of this?<br/><br/>Thanks.Sun, 17 Apr 2016 16:32:20 GMTchristinahaywoodhttps://forums.millisecond.com/Topic18925.aspxPreliminaries:<br/>#1: Make sure your Inquisit installation is up to date. The current Inquisit 4 release is 4.0.9.0, available via <a href="https://www.millisecond.com/download/">https://www.millisecond.com/download/</a> .<br/>#2: Make sure you have proper codecs required for rendering the specific video format installed (when in doubt about which codecs you might need, installing a codec pack such as K-Lite is an option; <a href="http://www.codecguide.com">http://www.codecguide.com</a> ). Alternatively, convert the video to a different format (e.g. WMV for use under Windows, MOV for use under OSX) and check if the issue persists.<br/><br/>If the issue persists after those steps, please provide the following:<br/>- What are the specific video formats you tried?<br/>- Under what operating system (type and version) are you seeing the issue.<br/>- If possible, a short bit of self-contained example code that produces the issue when run on your system.<br/>- If possible, a screen shot or two illustrating the issue.<br/><br/>Thanks.<br/>Sun, 17 Apr 2016 16:32:20 GMTDave
