Wirecast is a professional webcasting application developed by Telestream, that allows to stream video from several cameras, mix and add effects, and broadcast live events.
Usage and Failure Modes
Wirecast failure patterns correspond to failures during recording process:
- It is recommended to avoid using other applications during recording, as they can steal computing bandwidth and video quality can degrade.
- Lack of disk space can cause the Livestream recording session to end abruptly, leaving an unplayable video file.
- Any incidence during recording (computer goes to sleep, software crash, no battery) can potentially end the Wirecast recording session abruptly, leaving a corrupt video file.
Formats
Depending on software version and settings picked by user, Wirecast can output in a variety of container formats: .m4v, .f4v, and .mov
The video and audio formats found inside can vary, but most common combinations are:
Treasured is able to detect and preview footage in unplayable Wirecast videos in most cases. Providing a good file is sometimes needed.
How to repair a corrupt Wirecast movie?
When a Wirecast recording is interrupted before completion (for a number of reasons, see above), the resulting file is damaged and unplayable.
In most cases, you can recover the movie following a few easy steps:
- Find the damaged file in the Wirecast folders. This is usually the most recent file, and the one that you cannot open. The file could also be inside a temporary folder. You can create a Finder "Smart Folder" configured to display recently modified files to figure out where the file is.
- Check the size of the file to evaluate the duration of the recorded clip: Sometimes Wirecast crashes or stops recording well before you notice it, and the damaged movie file contains only the first seconds or minutes of the event. This can be verified by estimating the duration with the Time Calculator.
- Use Treasured to preview the damaged file.
- Send a Repair Request through Treasured if you are interested in recovering the lost video.
