Older Panasonic TM300 audio question
Gee, I just realized my TM300 is 16 years old! Ouch!! I’ve used this camcorder for quite a few years without issue. I have a very old edition of Edius that has worked fine for me through the years on my older I7 (circa 2010) PC and really never had any issues directly dropping the H.264 video right into Edius. This past week, I recorded a concert my wife was performing in, and none of the audio came through while editing with Edius, but Windows would play the camera H.264 video with audio without issue. My workaround at the time of editing was to process the camera video through VLC media player, Converted Video -H.264+MP3 (TS), and selected to “keep original video track” but process the Audio track via MPEG Audio, 128kb/s, 2-channel, 44100hz. This got me through the problem, but now I want to figure out what happened.
Today I took three short video clips with the TM300 with the Mic setup on the TM300 set for “surround”, “zoom mic”, and “focus mic”. I found the surround and zoom mic settings processed fine with Edius, but the focus mic was missing audio. I processed that focus mic video through VLC, and the audio came back in the converted file.
I ran the Zoom mic and focus mic through the Media Info utility and found very few differences, but some notable missing things in the focus mic file.
The bad audio H.264 has no “Inform” setting listed twice in the good file, like:
Inform : 12.4 Mb/s, 1920*1080 (16:9), at 29.970 (30000/1001) FPS, AVC (High@L4) (CABAC / 4 Ref Frames)
Inform : 12.4 Mb/s, 1920*1080 (16:9), at 29.970 (30000/1001) FPS, AVC (High@L4) (CABAC / 4 Ref Frames)
The good audio H.264 has no PCR information.
I realize there probably are not a lot of folks out there using this camcorder, but if you have insight on what is unique with that one mic setting on this camera, let me know.

Hi Steve,
There are a lot of variables when using old cameras and old software. I would try putting it into another more recent editing program to see if it opens properly. Sometimes when using older software, when the PC updates the OS, things get broken. You can download Blackmagic Design’s Resolve for free, or a Premiere Pro free trial. FXhome has a free version called “hitmovie,” and there’s another free editor called Shotcut, but it doesn’t read timecode which is a pain. See if any of these read the audio. I hope this helps.
Marc
