Recently updated my computer from Windows 7 to 10, and since that change my elements program is having an issue with sound disappearing with longer clips (4-15 min long), I checked all inputs and outputs for speakers and sound. wondering if this has something to do with the changeover, any help would be appreciated!
When you add a longer clip to your project, wait until the clip is fully conformed by the program before you start editing it.
You can watch the progress for the clip in the lower right of the program.
To re-conform your video, remove the video from your project by right-clicking it in Project Assets and selecting Clear. Then reimport the video into your project and, this time, give it time to conform.
