    Default picture quality issue...

    First Off i would just like to say Hi to everyone, im new and will be here alot more!.
    Nice to meet you all.

    Ive just came back from our holiday and did loads of recording.
    Ive plugged my camera into the PC via i-link, and imediently up pops windows movie maker. ( As i say im new to this so this) i sued this to take the film of the tape, as it seemed straight forward to use. so i let it do it, the speed was as if it were playing, so it took 60 minutes to take the whole tape off.

    Now the problem ive got is this,
    I viewed the recording using VLC player and it seems fine apart from theres like a slight blurryness of teh picture, mainly when i move the camera its like teh fps aint up to scratch, but if i view the tape direct through the camera lcd screen, the picture appears to be perfect.

    Is this a video format issue, or soemthing else?..

    Cheers for any help you can advise me with

    This is probably due to the shutter speed in the camera when you shot the footage.

    This controls the amount of time that the CCD takes to grab the image, if the shutter speed is low then the ccd is on for longer and any movement will smear the image slightly and when this happenes 25 times in a second it can look awful.

    Also check the file type, because win mm likes to use .WMV files to capture (unless you tell it otherwise) when you should capture in DV-AVI.

    Ah thanks for that ill give it a go.

    I checked the shutter speed setting and currently is Auto..but the other options are like, 1/50 to 1/5000..

    The shutter speed setting also affects the amount of light that the CCD has got time to absorb, so the higher settings will make the video dark. If you are outside in bright weather 1/250 is a good starting point, indoors you will probably not be able to get over 1/100.

    Use it in conjunction with the Iris/Exposure settings and see what works best for your cam.
