Editing and shooting questions using a Panasonic HMC40

[Dave Petteruto]

Thanks Dave–much appreciated.

One other question–after copying the video files to my computer, what is the best way to clear the card for the next batch of video to be shot?

Thanks
Dave P.

Quick Format (the default format for the HMC40).

While I believe it’s likely that any SD card used for typical camera media purposes will outlive its usefulness before it wears out (this has proven true so far, back to my first very early digital still camera, a Canon PowerShot 350, 0.3Mpixel), you still want to minimize wear. A quick format resets a few file system parameters, it doesn’t bother to actually erase anything. So it’s significantly less disc activity than deleting individual files.

There are frames lost or at least portions of frames lost. You may not see them or hear it when watching the video and that is fine if you’re intending on using the on board audio only for your video. Recently I had a 50 minute clip that I had synced perfectly to a soundboard recording track. By the end of the 50 minute the on board audio and the SBD track were just off to the point where you could hear the audio echo. The loss of frames (or portions) is the only thing I can figure would cause this.

You are doing something wrong then.

I record at a dance recital. I record the audio from a mixed board and sync it to the camera audio. I like to not stop recording so I only have to sync once (I do stop for intermission – so twice). This means on average I have 90 minutes (or more) of continues shooting for each half of the long recitals.

The audio syncs up 100% exactly. There’s no creep at all. What you are likely experiencing is again those goofy file splits that people seem to keep forgetting about. If you record something and there’s not a lot of audio or movement during the moment that split happens – you may not notice it except for that your audio (which won’t have the same split going on) no longer matches up with what your camera recorded past a certain period of time. [Whenever you hit that 4GB file size your audio will then be off past that point]

Of course it will match up at the beginning just fine. Try concatenating your video files into 1 file and see if that solves your issue.

Of course I have no idea how you are recording your audio, but more than likely that’s not the issue.
