DR-HD100 buzz in audio

This noise is well documented issue with the HD100 unit and quicktime files. Use m2t and Clipwrap. FE should do us a favor and instead upgrading to QT files provide Clipwrap user license instead. This would also avoid splitting files due to FAT 32 disc format.

This is a typical case of discovering afterwards. It did not search for posts about noise in QT audio before I went shooting with this setting. So I too have a lot of footage with the high pitched whine.

Wouldn't it be helpful if the moderators of this forum put up a sticky to warn about this issue?

Of course, Focus should fix it, but it in the meantime...

I noticed this problem too. It seemed to diminish on my camera when I closed the LCD screen while shooting.

Anyone else run into this problem?

Lots of people have this problem. The only way to fix it is to shoot .M2T files instead of quicktime and then use ClipWrap to rewrap the files as quicktime.

Hi, same problem, audio from tape is clear , audio from quicktime files is buzz and horrible hissssss, audio from M2T files is clear and good, we tested different mic, different lines, recording from a direct output from mixing console and the quicktime files is bad audio, when we decided from dr hd100 the most atractive reason was DIRECT TO EDIT, i think that this is not real than I expected. COnclusion, record in M2T rewrap or recompres from MPEG streamclip or compresor or something like that. I hope that Focus ressolve this issue, I really wish Direct To Edit.
