How to Change Buffer on VLC

Updated July 19, 2017

VLC Media Player creates a small data buffer in your computer's memory before playing audio or video content. If the player is temporarily unable to stream data from the source--your hard drive, a network drive or the Internet--it plays from the buffer until more data is received. If you find that audio or video content breaks up when you attempt to play it, the source is unable to deliver data quickly enough to meet your computer's demands. Increase the buffer size in VLC to circumvent this problem.

  1. Click the "Tools" menu at the top of the VLC window, and then click "Preferences."

  2. Select the "All" radio button in the lower-left corner of the window.

  3. Double click the "Input/Codecs" heading on the left side of the menu to expand it.

  4. Double click "Access modules."

  5. Click "File." Change the value next to "Caching Value" on the right side of the window to a higher number, such as "1000." This configures VLC to buffer one full second of content before playing. If you do not experience a problem playing content from your computer's hard drive, skip this step.

  6. Click "SMB." Change the value next to "Caching Value" to increase the buffer size for media played over your local network. If you do not experience a problem playing content over the local network, skip this step.

  7. Click "UDP" to change the buffer size for media played over the Internet.

  8. Click "Save."
