Video when I make a video with sound longer than 30 seconds , the camera doesn't work and doesn't save. Said error

It means that the video will last 10 seconds. 30 frames/sec is the quality of the video. It is the number of individual pictures take per second. Example: 10 frames/sec produces a jerky video but is sometimes used for security monitoring. On some cameras you can reduce the frames/sec to get a longer running time.

Be aware ti takes a camera the same time to save a camera, as it needs to shoot the picture. So if you shoot at 4 seconds, it will take at least 4 seconds to save the picture. When you are shooting under normal conditions, you won't notice it, because a shot from 1/30 of a second is saved in 1/30 of a second after you shot, It becomes noticeable when you use shutter times from half a second or longer, but it is absolute normal for any digital camera.

you can't.... it records only "video clips" without sound, maximum length of recording is 30 seconds...... and the quality is very poor, you'd be better off using an older camera-phone.

The camera depending on make and model usually will record from 10 to 30 seconds in most cases.

For uninterrupted video, you need a fast card. For example, if your camera uses an SD or SDHC card, it should be a class 6 or better.

To shoot longer videos, you need a card fast enough to keep up. Faster cards are more expensive but if you shoot a lot of video, it may be worth it to you.

Try rechargable NiMH batteries. They are specifically designed for today's technology, and last much, much longer than traditional batteries. It doesn't matter about the brand -- Energizer, Rayovac, Duracell, generic -- I've found that they all tend to last about the same amount of time in my digital camera. But I only use rechargable ones anymore.

Solution: Bring it into your retailer. Mine did the same thing in 2008 (I'd open up camera and it would just freeze). AT&T gave me a brand new phone, save the sim card, battery, and battery cover.

P.S. I'd back up all your photos/videos/ringtones/etc. to and SD card so you don't lose them all like I did. Contacts saved to sim card stay.

hi, It should not problem with flash card but while you placed it some setting must have changed Sangita

Only the card size. The bigger the card the the bigger the file. your manual should tell you how many images or video length you can get on a given size of card.
