High bitrate files may play back choppy on the timeline. High bitrate files commonly include files recorded on a HD camera, such as MOV and MTS files.
The following items may improve playback on the timeline in Camtasia:
- Change the power options on your computer to High performance.
- To improve performance, make sure the Editing Dimensions are the same as the source file. For example, if you import a 1920x1080 video and set the Editing Dimensions to 1280x720, Camtasia may use more processing power to scale the video.
- To view the source file dimensions, right-click the file in the Media Bin and select Properties (Camtasia 9) or Details (Camtasia 8).
- To view the Project Settings in Camtasia 9, select File > Project Settings > Canvas Dimensions. In Camtasia 8, see the example below.
