When you play the clip in a media player, can you hear the audio? Sounds like a codec issue, but seems odd that it would produce a clip that it cannot play. __________________________________

Plays fine, both audio + video.
Just can't see the wave form in the audio track (it won't display, not play) Chuck Puckett

Hi Chuck,
You're aware I'm sure, as a member, we often ask the same questions and are particularly demanding for specific data.
1. Please supply details of the version of PD9 you're using - update to the latest patch would be good.
2. provide a screenshot of the Edit workspace with the mp4 in the track
3. The full list of actions which you carried out and did you repeat the process after shutting down and rebooting.
4. provide an example of the video you created 5 to 10 seconds long will suffice. Members can then test play and then display the video in the Edit workspace/video tracks and see if they can replicate.
5. Please supply a 5 to 10 second mts file you have tested the issue out on and replicated the problem.
Thanks
Dafydd

PD Version: 9.0.0.2504

The screen shot will reveal one MP4 that does show audio, one that does not, as well as an MOV file that does not show audio. I have had this display/not display problem move from file to file.

The MTS files do not have the problem. Why do you need them? And you only allow 3 attachments.

The ASUS GTX570 drivers are up to date.

What I did:

Create new project, open MTS file, split and trim, write out as MP4

Ditto for another MTS file

Create new project, add the two MP4 files, another MTS file and a MOV file.

For the ones I can see the audio track, use drum rim shots to sync the video.

Cannot see some video, so process is incomplete.

It appeared the MP4 attachment did not succeed. At least, I only see 2 files listed. Try again Chuck Puckett

Ok, I see what you are saying. I had that problem with PD8. It would display, but take forever. I am downloading the mp4 and will have a look. __________________________________

I apparently still have 2330 installed. Downloaded the latest patch last night, but for now I imported the video clip and the audio wave form came right up. I don't know what else to say about that.

Your system looks to be more than capable. Video drivers looks recent. I've got nothing. __________________________________

Probably, as indicated in your screenshot, because your shadow edit files have not finished generating. I doubt you need them with your system. Try turning them off.

Jaime: that's the second hint I've heard that 2330 (or some previous patch) was somehow superior to 2504. Also, as I mentioned, it is NOT specific to a particular input clip; the phenomenon "moves" around. Frankly, I was surprised that it manifested on the 5 second clip; intuition (and a certain logic) would imply that it might be at least partially dependent on clip length (ie, amount of data). I added the 5 second clip to my project, and observed that audio track failed to display, and so sent it in to the forum. Note, however, MY PROJECT ALSO ALREADY HAS THE OTHER CLIPS IN IT (I presume the project you used in testing the clip did not). Function of the number of clips?

Adrian: "shadow edit files"? Not sure of the term, nor how to turn them on/off. I know I use "fuzzy" mode for HD clips (or whatever you call the imprecise view of those clips when placed in the timeline). I also know that I have waited a considerable time for audio tracks to display. My experience has been: those that display, display instantly. Those that don't, no (reasonable amount of) waiting changes anything.

One last, perhaps reddish herring-like observation: When I first bring up the project, and in fact when I add a clip to the timeline, often I see nothing (even for the "good" tracks"), until I diddle the zoom. No audio track display, zoom the view a twitch, voial! audio track displayed! Chuck Puckett

Chuck,

Take a look at your screen shot. In the lower left of the clips in the media library you will see a small yellow film clip. This indicates that the shadow files are being generated. When they turn green the files are completed. Editing should wait until all the clips show the green film clip.

To turn off the shadow file generation, go into preferences, on the general tab uncheck the box 'Enable HD video processing'.

See attached screen shot.

Hal,

Started a new project for a new song. 4 video clips (3 MTS, 1 MOV) and 1 audio clip.

Everything turned green.

The MOV clip and one MTS clip display no audio track.

The other two MTS and audio clips do.

Turned off ''Enable HD video processing'. No change.

Exited the project and restarted. No change.

Did notice that the failure may in fact be camera-specific. The MOV file (from a Zoom Q3) consistently fails to show audio. The other sources are from two Lumix cameras and one Vixia. The Vixia and one Lumix seem consistently to show audio, the other Lumix seems consistently to fail.

Curious that one Lumix works, one does not. What settings in the camera could affect this? And, yes, the audio is THERE, i can play it and hear it. Chuck Puckett
