They're the same as I"ve always used.
However, the problem seems to have sorted itself now? All I can think it is, is that Premiere is having to maybe convert the audio codecs?
It was just a bit weird that it suddenly started happening.
But as per your request, I think this is the right info:
Type: QuickTime Movie
File Size: 3.1 GB
Image Size: 720 x 576
Frame Rate: 25.00
Source Audio Format: 48000 Hz - 16 bit - Stereo
Project Audio Format: 48000 Hz - 32 bit floating point - Stereo
Total Duration: 00:14:24:05
Average Data Rate: 3.6 MB / second
Pixel Aspect Ratio: 1.4587
Thanks for the help
