I want to update my findings. Specifically its Panasonic’s interpretation of their AVCHD and MP4 file formats that reduce the audio when pasted into a video editor such as Vegas, Adobe Premiere or Camtasia. The audio line/level is almost flat and requires artificial amplification. Bummer. My older TM90 does not exhibit this problem and neither does the Canon G20 which I borrowed yesterday.

I love Panasonic products and this is rather frustrating. Video from the 770 plays nicely from the camcorder itself when plugged into a TV. However the background white noise is very noticeable when played on computer with Windows Movie player or the TV. The 770’s predecessor the 750 (which I sold) also had even poorer audio in all respects and most likely Panasonic somehow pumped up the 770’s amplification. Bad Panasonic!!! Just fix the problem and stop trying to put a band-aid on it. I sent my 750 to Panasonic for repair, they said it was fine so I traded it in to B&H (lost $200) and got the 770. Feel ripped off. Comments appreciated.

750 poor low audio, X920 and 770 both have the same audio issues. With all 3 having the same low audio line when pasted into a editor.

Move on to Sony? Cannon? Hard choice.

Here is a Dropbox link. Files from the Panasonic HC-770 and the Panasonic TM-90. Past them into Vegas and see the flat audio on the 770.

Thanks for your response. I’m pulling my hair out on this. I’m running Win7 on my Home computer and Work computer with both having. Attached is a screen shot of a short file in Vegas P11. The audio blips on the audio line are me speaking rather loudly, talking to my wife’s cat.

I know very little about file formats, but I don’t believe I should have to artificially raise the audio thru a converter. I’ll upload a Vegas file with my old TM90 and the new 770 pasted in. Both cameras in Auto.

Attached is a screen shot of a short test I just made. You can see how flat the audio is. From my 770 in full auto.

My Panasonic HC-V770 encodes video using the MPEG-4 AVC/H.264 codec, and was told, this codec is not suitable for editing in most non linear editors including Vegas, Adobe Premiere and Apple. This problem seems to be found throughout the Panasonic camcorder product line.

While the Panasonic video format can be opened in Sony Vegas, the audio level is almost nonexistent and requires an audio FX to raise the volume, thus introducing white noise.

I’m a little frustrated with Panasonic. Every function is set to auto, with no modification to the Audio in the camera. A friend said to get out of the Panasonic line and into Canon.

I just can’t believe Panasonic would allow such an issue.

Comments appreciated.
