VS X5 loses sound between clips?

Hi David

Thanks for the sample project files.
You will find them for download here. Including the new Super converted file.

There are some differences with the three video files I had expected to find three identical video files, Direct from the camera without any additional rendering.

The first video "A" uses 4:3 ratio but has a black border embedded top and bottom?
The audio uses 48Hz Digital Dolby

The second Video "B" uses 16:9 ratio, it does however display correctly as 16:9, the audio uses 32 Hz rather than 48Hz however I do not think this is the problem, more likely a corrupt mpeg video file
The video will not play audio in project playback, Video Studio does not read this file correctly.
I have tried converting this clip using Video Studio without success, However Super seemed to do the job.

The third video "C" this seems to be the best sample, does not seem to be not modified ---- Widescreen 16:9 displays ok.

So what have you done to the first two.?
Have you used another program to convert the video files?
Have you renamed the files changing the extension to Mpg.?

Trevor,

I did mention the process I used but to summarise:
- the camera (JVC GZ-MS100AA) records as .mod. Don't know why. I have seen players that would not work with that, altho maybe that is changing. It was a while ago. I back those off-the-camera files up as is, and also burn to DVD as a further precaution.
- However, VS works with and produces mpg files for normal consumption so my next step is to render/convert the .mod files to .mpg stored in a separate location with standard project settings and those become the ones I edit and work on to get a final video/movie.
- that process has never before changed the sound in a clip, and I don't think it did this time. Clips A, B_1 and C which have good sound were all done that way. Clip B was originally like that. I mentioned in the first post that I had tried to trim the preceding clip (A), something went wrong, and after that the sound issue with clip B was there. How, I have no idea, but you've seen the files, and the various image shots in the issue.

The only program that's opened and worked on the base files is VS - initially 11Pro+, but since March this year its been X5. Once saved from X5 of course 11+ will not open a vsp, gives a file format error. This particular set of video files was converted to .mpg using 11+ about a year ago, and the base VSP (just an assembly of the video clips no transitions or any other editing done) was created with 11+ about 9 months ago. When I began to work on/edit the files it was with X5 (starting about 2 months ago) and any trimming, cuts, volume variations, transitions, titles, music etc have all been applied using X5.

Regarding the aspect ratio - settings are usually 16:9. I sample checked about 5 of the clips prior to A and they were all 4:3, whereas from B onward they are all 16:9. Since those files were recorded in close sequence I cannot understand how or why I would have changed the camera aspect aspect ratio just then, but it seems that was the case. I mentioned in the issue (when I saw this) that I would have some rework on the affected item to do, which is to re-do them (quite a few as it turns out) in 16:9. As to why I did not notice it earlier - the vehicle had rather limited windows and the window frames pretty much appear as black edges in every earlier clip, so even when shot in 16:9 it looks like 4:3. Afterthought - maybe that's a good reason not to bother?

You mentioned something about Super fixing it. Since the clip basically retained its sound but would not play it in project mode, Super must have turned off whatever was causing that condition. Can you clarify what Super is and what it did? And how does one get this handy tool?

Hi David

Did you manage to download the Super mpg version file.

Super has been used by the forums members for as long as I can remember.
The Super site does however try to get you to download anything but Super.
Not a good site to navigate, the actual download link is on the third window, I think
You have to scroll through the pages to find the correct link.

http://www.erightsoft.com/SUPER.html

Just to help I found this direct link

http://www.erightsoft.info/GetFile.php?SUPERsetup.exe

The program is not that intuitive and does take a little time to understand what properties to set, well I find it that way.
------------------
The aspect ratio issue, if you set the camera to 4:3 then it looks like the camera is adding the black bars, you can convert the 4:3 to 16:9 simply by distorting the frame, reading my guide regarding Widescreen 16:9 may help.
Easy to check, do a test recording at 4:3, does it contain black bars?

-------------------
Mod files,
Are you sure VS will not import these types

Try renaming the Mod files to use the file extension MPG rather than recoding / converting them.

Flying view before the plane . . . .

Will check the Super item on return.

Re mod files. It isn't that VS won't open them, it most certainly will. At the time, it was just about the only video tool I had that would. The upload tool that came with the camcorder was clumsy and slow, so I just remove the SDHC card that has all the files and plug it straight into a card reader usb attachment for the computer. The other players or tools would not open a mod file: but they managed fine with mpg files. So I got into the habit of converting mod files to mpg files (that everything could use) using VS before doing anything else. Since then, there have been OS upgrades as well a newer versions of the video tools, including VS, so the previous condition seems to be abating, and hence my remark. For example, the media player that comes with Windows 7 does a better job of reading various media files than its counterpart that was part of XP.
