Encrypted file from digital camera?

[csrocha_guara]

This is my first post. I use VS XP Pro, and never before I did experienced what happens now.

I am trying to edit a simple movie file from a Sony Cybershot W55 camera, MPG format. But even in small files, VS freezes and I have to reboot the computer. I tried it in 2 different computers and no success. I use VS since version 4 and never did see something like this issue.

Could it be encrypted files? Ou a virus? Any idea?

Thanks and excuse my poor english.

And, finally, happy new year to all.

Welcome to the forums,

Your video clips are some form of MPEG-4 correct? If so that may be the problem. Could you right-click on one of your clips, in the timeline or library, select properties and post them back here?

I think this might be case of the "Lite" version of the video format!

As Ron requested, these are properties of a small file from the camera:

File name: C:\....\MOV02117.MPG
File format: MPEG-1
File size: 11.502 Kb
Duration: 32.400 seconds
Video
Video Type: MPEG-1 Video
Total frames: 810 Frames
Attributes: 30 bits, 640 x 480
Frame rate: 25.000 frames/sec
Data rate: Variable data rate
Audio
Audio type: MPEG Audio Layer 2 Files
Total samples: 1.036.800 Samples
Attributes: 32000 Hz, 16 bitx, Mono
Layer: 2
Bit rate: 54 kbps

My friend, the camera owner, told me that, after copied the files to a CD-Rom, playing it in a home DVD Player, when he plays it foward (double speed ou more), backing to normal play, the image freezes, but sound goes well.

In the while I posted my doubt an now, I downloaded a Software - Any Video Coverter, which was capable to convert to a DVD format, readable normally in VS. Despite this solved my problem, I am curious about the matter.

PS. Despite I work with video editing (homemaking), I dont know much about video format differences.

Ok, the video actually is from an SVCD or VCD? The file format is wrong for DVD standards.

The frame size should be 720 x 480 (NTSC) or for PAL 720 x 576. The frame rate looks to be PAL, which is 25fps. If you're in the US or other NTSC area the frame rate must be 29.97fps. DVDs use MPEG-2 video file format.

While you can use MPEG-1 video clips in your project, just be prepared for a loss in quality, especially if you're using it in a fit-to-screen. It will be re-sized to the appropriate frame sizes.

I would guess that VS had a problem because the file had some degree of corruption. Even though you may be able to play the video, however trying to edit files will reveal even the minor corruptions. Running the file through AnyDVD Converter probably corrected the corruption too.

Thanks very much for the explanation.

I think this is the point. Fortunately I had to make only a minimal editing this file, only 8 minutes of a speech to be converted to wmv file to publish in a website. Consider my case as resolved.
