Riverside Audio and Video Out of Sync or Drifting

How to fix it

Try these in order — the most common fix is first.

1. 1. Match frame rate and sample rate

   Copy steps
   1. Check whether the files are variable frame rate and convert to constant frame rate (for example with HandBrake)
   2. Set your project sample rate to match the audio files (48 kHz or 44.1 kHz)
   Did this fix it? Yes No

2. 2. Try another export route

   Copy steps
   1. In Premiere, export through Adobe Media Encoder instead of the built-in export
   2. Render long episodes in shorter segments and join them
   Did this fix it? Yes No

3. 3. Get support involved

   Copy steps
   1. Send support the project link and the point where drift becomes audible
   2. Ask whether the tracks can be re-processed
   Did this fix it? Yes No

Why it happens

• Variable frame rate video in the editor
• Sample rate mismatch (44.1 kHz vs 48 kHz) between files and project
