I have a canon SD 580. When I playback the video clip it's always in fast forward mode and I can't play it normal speed. Any help?

Unfortunately, no. By recording in fast mode, the camera captured fewer frames than usual. When played back at the normal speed, the action appears faster than normal. Because the camera recorded fewer frames, there is no way to make up for the images that were not captured. You could slow down the playback, but the result would be a jerky, jumpy video.
Now, if you had accidentally captured the video in slow motion, you could then throw away some of the intervening frames and recreate a normal-speed video.

I think this is what you are after if this isn't what you need you can find the manual at
http://www.retrevo.com/support/Sanyo-VPC-CG9-Camcorders-manual/id/18378dj397/t/2/

First, make sure you have it on CARD (and not DISK), and on the "playback" (and not record) mode. Next, does the camera play back other video clips normally, but just not a specific clip ?
Does the selected video clip frame (index) shown on the LCD screen have a picture ? If not, i.e. it is blank (dark), then it is likely that no video was recorded (i.e. just the audio) when you were shooting that video clip.
If there is a picture (of the video clip frame index on the LCD screen) and only audio is playing, try downloading the clip (from the SD card) to your computer, or simply try to play the video on the SD card (inserted directly into your SD card reader on your computer, or via a USB SD card reader) and see if the video clip will play normally on your computer.

It sounds like you may be in "Fast Frame Rate" video mode. Turn on the camera to video mode, then press right/left to select normal 640 pixel video. (Depending on the camera model, you may or may not have to press "Func" or "Func Set" first).

Oh my, sounds like you accidentally recorded in "Time Lapse" mode (one of the specialized video features of your camera). Unfortunately, there's no way to convert the already taken video back to "Standard" video with sound, I'm sorry. However, you'll obviously need to set your camera back to standard mode for future videos. Press the "Function" button while in video mode. Then press left/right to select "Standard" video.

what format is the video in ....

U will have to edit the movie on a video editor ..... Ulead video studio is a good one ....... get ur video on it ...reduce playback speed according to choice and create a new File

I have a Powershot SD1000 and it should be similar.
When the video plays very fast it was probably filmed in Timelapse mode( which fast- forwards the video) When you are in video mode press the SET Button and set the camera to Standard mode

Make sure that you're not on timelapse, it should be standard to do a regular playback.

Record in slow mo mode, then playback in fast forward mode ;) Problem solved. You'll see the video in normal speed.
