什莫软件效果比较好呀？谢谢

首先得用DV自带的软件把图像导出来,比如.avi,.mpg
然后再选codec压缩,可能有的软件把这一步和上一步合并了.没压缩的avi文件非常大

1. Assume you are using Digital Video Camera recording with DV tape.
(this is different from digital cameras that can record short videos in quicktime format.)

2. You need a computer equipped with capture card.

3. You need capture software. Capture cards will come with capture software. Example software would be DVRapter, DVstorm and so on.

4. You may want to edit your videos (cut, combine), you can use editing software like Adobe Premiere to do that. You can use the Export function in Premiere to help you decode.

5. For furthur inqueries, you can consult(For NUS)

mpeg用了motion estimation，也就是说，为了减少冗余信息，他们只关心改变的地方，连续frame之间的变化他们用向量来描述，而且由于采用了block motion estimation，一个向量描述一个方块， 当然会丢失很多细微的数据。有时候会有错误发生，导致图像错移或出现扭曲。
