Record marked as obsolete and not updated for a long time.
The m1pg file extension was used by iFinish, a video-editing program that is no longer developed. iFinish was later replaced by Media 100.
The format is obsolete and was intended for video clips saved within the iFinish editing workflow. It is not expected to be supported by current general-purpose video players or editors.
Open an m1pg file with the original iFinish software on a compatible legacy Macintosh system. Current video applications may not recognize this obsolete format.
If iFinish is available, use its video export functions to save the clip in a format supported by current video software.
