Re: hard drive full & cannot delete

There is a reset button on the camcorder. To access it you have to use a paperclip. First I would try to format it from the menu screen within the camcorder and then reset the camcorder to factory. This would delete all the files.

Can't play back videos on my experna; memory card Sandisk class 4 8Gb. Have a canon Vixia HFR10 camcorder

Okay, ours is a different brand (JVC) but they may have some basic similarities in function. To playback video clips stored on the memory card, put the memory card in the card reader slot of the computer and put the files onto the computer. Playback the clips from your computer video or photo file. (Ours won't playback video stored on the memory card through the camera.)

To playback video clips stored on the camera hard drive through the camera, we open the viewer screen, look at the function keys on the camera body, select the "Play" button. On the screen it displays thumbnails of the various video clips. We use the toggle/function key to select from the menu containing options for playback, edit, delete, protect, etc.

I have deleted all files, but camera says Hard Disk Full

On page 39 of the instruction manual it tells you how to format both the hard drive or the SD card. If you do not have a copy of the manual here is the link:

click the "instruction manual which is the fourth choice...

also be sure any medium (HD, SD) is UNLOCKED when doing this. If you do not weant to completely format see page 40.

And for your comfort, a Mac does not convert anything on the camera. But for the future, don't drag and drop into the trash bin, use delete on the camera. This is the same problem I've seen w/others but calling Apple-who blames it on the PC format-who blames it on the Mac-and both blame it on JVC, gets you nowhere. This is very typical when multiple companies are involved.

If you need further help you may contact me privately.

Using my ultra flip camera: when I playback my videos on my computer the images are choppy, jumpy or in slow motion while the audio is fine. what can i do?

Two possible Solutions

1) Have you transferred the videos off your flip, and on to your computers hard drive?

USB ports have greatly increased in speed in the last few years but they can still have trouble playing "live" video directly from the camera.

Solution: Plug in your flip. Drag the files to your "desktop" or "my documents" or any other place you like to store them. Play the files from there.

2)Does the video playback ok on your flip? Or on a different computer?

If so the solution is simple, but expensive. Your computer does not have enough processing power/ memory to play back the video. Full uncompressed video is a very large file and most computers older than 2 years have trouble rendering the video frames fast enough. The HD we see on sites like youtube and even on Blu-ray have been compressed. When the files come off the camera they are not compressed and require alot of computing power.

Solution: Buy a new computer. Sorry I know it is an expensive fix. The good news you don't need anything too fancy. A laptop with a 2+ Ghz (gigahertz) processor and 3+ GB of memory, will do the trick and cost between $300-$500.

Hope that helped

Go to your "my computer" icon on the computer and you should be able to see all available drives on the computer. Your camera should appear as an external hard drive. You can open the drive and then open the files in the drive. Simply click and drag the files from the camera to your video folder on your main hard drive and you are good to go. Windows Media player should play the videos....or use an editing software like power dvd.

Lost all video files from harddrive

Hi, John. First things first - do not take more photos and do not save anything back to the camera memory card. Then connect it to your PC. Pick a digital camera recovery (recover photos, video, music files) to make a free scan and recover the deleted photos. Regards
