When I open my video files on QuickTime player, something strange happens! Its choppy playback issue bothers us a lot and we don’t know how to resolve it. Can anybody help please?

Apple’s QuickTime player has been developed to play back digital audio and digital video files with the best quality it can present. It is not only used in Apple devices or systems but also Windows. Users may use it a lot during daily life but if they accidentally encounter the QuickTime choppy playback issues, it is recommended to read this article carefully for solutions.

Part 1: Several reasons for that choppy

QuickTime choppy playback issues occur due to various reasons; some are typically related to the media player's settings or the video's encoding. Here we would discuss further the root causes leading to choppy playback issues. Read on!

  • Playback settings
  • By default, audio and video tracks are tuned to the same rate but recently QuickTime's default playback settings may have been adjusted. This results in the unmatched audio and video tracks to stream at different rates. It is also possible that a timing offset was programmed between the two tracks. Users can investigate QuickTime playback settings by going to "Window" and "Show A/V Controls."

  • Codec
  • It is possible that the video may have been compressed with a codec that is not supported by the computer. A codec is an algorithm that codes and decodes streams of media like audio and video. It is tricky when a media player is not equipped to stream a particular video codec, playback may be choppy. That explains QuickTime choppy playback to some extent. For advanced users, they may use third party software like GSpot, VideoInspector or MediaInfo to identify a video's codecs by running the media through the above analyzer. Once users have identified the video's codecs, they can install free plug-ins to enable playback for the media.

  • Streaming
  • Another reason for choppy playback may blame the media streaming. QuickTime can also be used to stream embedded Web video. If online media appears choppy, it could be because the media player's streaming settings need to be tweaked. Users can stream QuickTime embedded video more smoothly by increasing buffering time. When media has more time to buffer, more of the content is downloaded before it is played. Users can increase buffering time in QuickTime by going to "Edit," "QuickTime," "Preferences" and "Streaming." Raise the marker on the "Play Streams" scale closer to "Short Delay."

    Part 2: How to fix the issue

    Since we know the common causes leading to the QuickTime choppy playback issue, it is highly recommended to fix the choppy issue with practical solutions. Here we have collected the most useful tips and tricks to solve the QuickTime choppy playback issue.

  • Check bandwidth and system capabilities
  • Check the files for bandwidth requirements and compare them with system capabilities. It is because QT automatically drops frames if it cannot keep up with playback requirements which can create choppy playback issues to complete "freeze" of playback. This could be a proper solution to fix the issue if you are going to play high-resolution videos files.

  • Download and install some sort of codec or plugins
  • Suggest check and identify what codecs are used in the video files and download free plugins to facilitate the smooth playback of videos files on QuickTime and avoid any choppy issues.

  • Increase buffer time for web streaming video
  • If you are playing web video, suggest increasing the buffer time, which means more of the content is downloaded before it is played. To do so, simply go to "Edit," "QuickTime," "Preferences" and "Streaming." Raise the marker on the "Play Streams" scale closer to "Short Delay."

  • Update the QuickTime to the latest version
  • All too often, when your QuickTime player becomes “old”, it lacks support for some advanced applications. Problems may occur during playback of some sort of video files, especially those with advanced codecs. To solve this, simply update QuickTime to the latest version and try to open the video files again. Apple has invested and pushed for updates from time to time, which aim to solve issues and make playback more smooth and enjoyable.

    QuickTime choppy playback might not be a serious problem if Apple realizes this and fixes it in its latest update. Therefore, it is always recommended to keep your QuickTime Player to the latest version and problems will be resolved by itself.
