Yes, a long time ago. I have "QuickTimeInstaller, 7-79-80-95.exe"

@Yelandkeil I discovered the anomaly of waveforms coming and going on the 32bit float.

In VP 22 if you zoom in to the timeline more than 4 clicks (+) the waveform disappears on the 32bit file, but not on the proxy file. So I must have been zoomed in when I said that there was no waveform available.

Dexcon mentioned "In Preferences/Quality, Audacity does have a 32-bit float Default Sample Format setting - as does Sound Forge Pro (and it also has a 64-bit float option). Conversely, Vegas Pro in Preferences has a maximum sample format setting of 24-bit."

 

That may explain why VP cannot play the audio.

@Dexcon However, I cannot find that setting in VP preferences?

That's its output format, not related to input decoding.

But VP's user manual states about that:

Bit depth

Select a setting from the drop-down list to specify the number of bits used to store each sample. Higher values will increase the quality of playback and any recordings that you make.

If the maximum setting in VP Preferences is 24-bit , it's hard to believe that VP will import other media over 24-bit when it can't record anything above 24-bit. If VP can't record above 24-bit, why would it be able to import audio at above 24-bit? It makes no sense - to me anyway.

VEGAS can certainly read and edit 32 bit float audio. However that's in a wav container.

This new Panasonic video format with 32 bit float audio embedded is likely not yet supported by the VEGAS decoders as it's an unusual combination.

After reading the discussion here, I think that the best solution is really either to use the proxies. Or - if not available - to use the free Shutterconverter as suggested here. Works fine also in my tests.
