iMovie CompressorKit Error Fixed

iMovie CompressorKit Error is a well-known issue reported by large amount of iMovie users. The full name of this error is: " error -1". However, there doesn't seem to be any one cure. Since it's pointed to compressor, it's probably has something to do with incompatibility codecs. But prior to that, basic diagnosis includes:

  • Rebooting your Mac
  • Relaunching iMovie
  • Delete iMovie preferences
  • Create new Library in iMovie
  • Trash and reinstall iMovie
  • Reinstall MacOS

iMovie Error "RequestFrameAt Returned: N for absolute frame: N"

This is a common iMovie error reported by many iMovie users. As the error message indicated, there should be problem at the given frame of the rendered iMovie video. How do you know which the specified frame? You don't need to. Just go to play the exported video (if there is, incomplete yet), it's the culprit where it stopped. Remove or replace the corrupted clip and try to export again. If you do want to count the frame, this frame to frame converter is helpful.

However, the above solution may not work for your problem. Also try to update/redownload your iMovie, delete iMovie preferences (opening iMovie while holding down the Option and Command keys), boot macOS in Safe Mode (see Finder menu for instructions) and immediately shut down and reboot in normal mode, and so on.

According to our experience, format incompatibility or file corruption may also cause this problem, make sure your media files are compatible with iMovie. MP4/AAC or .mov are preferred by iMovie. If not, use a video converter to convert them to the suitable formats.

The solutions introduced above might also work for another similar iMovie error: "RenderFrameAt Returned".
