Stuttering Video Playback Due to Incorrect Audio Input Settings
On Windows 10 PP2021, any video file would stutter in playback.
Seems to have been due to a mis-configuration between the microphone input capability on my system and the configured of audio sample rate and bit depth on the mic input.
Originally, on a fresh install, premiere defaulted to:
Input - 2 ch 32 bit 44.1kHz
Output - 2 ch 32 bit 48 kHz
Setting input to "No input" resolved the playback issue with output set to the above 32bit-48kHz setting.
Matching input and output to:
2 ch 24 bit 48 kHz
Resolved the playback issue as well.
Again, seems that premiere sets the microphone input to an incorrect value that the system isn't capable of and causes a stuttering playback issue.
Since 24bit-48kHz is the tv/film standard for what is considered high-quality audio, please default Premiere to those settings.
