In fact ,I use one mov which is progressive to generate on metion jpeg mov ,but the default is always interlaced, You mean we can’t set the property(interlaced or progressive ) to codec ,just only can deinterlace the generated file to progressive one ?

M-JPEG is always interlaced, that is, the even and odd field are compressed separately.
Don't worry, if the original is progressive you won't see any interlace-like artifacts because of this. The compression is simply a little less effective.
If you want more effective compression use Photo-JPEG.
