Troubleshooting Vegas

Following this checklist should solve most common issues with Vegas Pro. Remember to actually do all of the steps, don't just skip over restarting your computer because you think it won't matter. Some settings mentioned are not available in all versions.

Checklist

• Restart Vegas.
• Check project and source framerates are the same
• Check for stacked keyframes
  • Sometimes two (or more) keyframes can occupy the same frame "on top of each other". Try moving the keyframes around the problem frames to see if there's multiple keyframes on a single frame.
  • Try cutting the clip at the problem frame, this should force the keyframes to separate.
• Restart your computer.
• Move your source files onto an internal disk, preferrably an SSD. Do not use an external drive (HDD or SSD) for editing, it will suck.
• Check how much RAM you're allowing Vegas to use in the video tab of preferences.
  • Not giving Vegas enough ram can hurt playback performance. Giving Vegas too much ram for previewing can hurt rendering performance.
  • Earlier versions of vegas used to have a bug that the RAM slider completely irrelevant. This has been fixed in later versions.
• Make sure your GPU is selected in the "GPU acceleration" dropdown menu in the video tab of preferences.
• If nothing else works, hold ctrl and shift while starting Vegas until the "reset all Vegas Pro preferences" dialog pops up. If the normal Vegas splash screen loads, try again. Select "clear cached data" from the dialog and click Yes
  • If you can't get the dialog to show up, try opening Vegas directly from it's executable (right click vegas shortcut > open file location). Remember to still hold the keys.

• Try disabling / enabling GPU acceleration of video processing in the video preferences.
• Try disabling / enabling OpenCL/GL in the internal settings.
• Try disabling / enabling the So4 compound reader in the internal settings.
• Enabling legacy AVC and HEVC decoding in the File I/O tab in preferences can stop Vegas from crashing but simultaneously makes you unable to use 10bit sources.
