Videos are scrambled
There could be a number of reasons for the scrambled video. Without knowing more details, I can’t offer a sure-fire solution. However, maybe I can point you in the right direction. If you have the camera connected to your television, it could be a compatibility issue between PAL and NTSC. NTSC is the video standard for television in the United States. In other parts of the world, the standard is PAL. Resolution for NTSC is 720x480; PAL is 720x576. The two standards also have differing frame rates. Digital still cameras can often record in both NTSC and PAL. Camcorders don’t have this ability. If the camera is gray market or imported, it may only record in PAL. Your television is set to display NTSC. A discrepancy could cause playback problems. You may be able to set your television to display PAL video. You can try this to see if it makes a difference. The difference between PAL and NTSC shouldn’t make a difference if you’re viewing the video on your computer. However, if you’re using a television, make sure the video is converted to NTSC. If the video is on a memory card, perhaps it was zapped by static electricity. Static electricity can erase memory cards. Or, it could cause problems with the information stored on the card. Some programs are designed to recover data from a memory card. These may help if you’ve lost entire files. I doubt they’d help in this situation, though. There could also be a problem with your computer. But it is unlikely that the problem would only affect certain videos. You would have problems watching any video on the computer. But try another computer just for laughs. If you’re watching the videos on your computer, it could be a codec (compressor-decompressor) problem. Codecs are somewhat difficult to understand. They are used to compress and decompress video. Codecs are different from file formats. For example, you could have two AVI files that use different codecs. If the correct codec isn’t installed and associated with your player, you’ll have problems. Often, the video won’t open at all. If it is a codec problem, it is relatively easy to fix. You just need to find the correct codec. For more on codecs, visit my site. Of course, if your videos are stored on tape, the problem could be more serious. If the tapes were stored near a magnetic source, you probably won’t be able to recover the video. Speakers, monitors and audio/visual cables can degrade your video. That goes for analog and digital tapes. Coming up in tomorrow's Tip: A projector for HDTV. Are you in the market for a new cell phone?
