I'm attempting to remove some video noise/grain in iMovie 11 taken in low-light but haven't found a way to do this within iMovie itself. I've looked for plugins but the only ones I've found don't have free trials and I don't trust paying for software if I can't be assured it will work.

Is there a way to remove video noise/grain in iMovie?

  • Grainyness is caused by a high ISO; used in settings of low light. I'm not really sure that can be fixed. For future reference, use a higher exposure setting, not a higher ISO setting. – daviesgeek Jan 27 '12 at 19:41
  • @daviesgeek You're right in saying that noise is a result of a high ISO, however I'm aware of that (I'm also a photographer) and noise/grain can be removed at least partly by comparing two neighboring frames and judging what of the resulting images is noise and what is actual data. I've seen stand-alone programs that do this for video, but iMovie doesn't seem to do this and so I'm looking for a plugin that adds this apparently missing functionality. :) – Bendihossan Jan 27 '12 at 21:19
  • Ok, that makes sense. – daviesgeek Jan 27 '12 at 21:28

Unfortunately iMovie doesn't take plugins.

Best bet is external software OR Final Cut Pro 7 has numerous plugins that reduce noise and grain, but they are all very expensive.
