It is recommended that files in the same Play List or reel be of the same resolution, frame rate, and codec.
Playback Rate of Audio Files
Audio files (WAV) are always played back at the sample rate of the PIX 270i. The sample rate that
the file was originally recorded at (and that is stamped in the file’s header) will be ignored by PIX
270i during playback, and the PIX 270i will play the file at the current sample rate, as determined
by Setup Menu option [Timecode/Sync - Sync Ref - Audio Only Mode]. When Setup Menu option
[Timecode/Sync - Sync Ref - Audio Only Mode] is set to Internal, audio files will play back at the
sample rate of Setup Menu option [Audio - Audio Mode Sample Rate], even in Video Mode.
Non-Native File Playback
The PIX 270i can playback QuickTime .mov files and PCM .wav files generated by third party ap-
plications and devices.
