When a digital camera records footage, it actually records 48 pictures a second and combines every 2 pictures into 1 frame to create 24 frames per second that is standard to film. This will result in a combining of the footage that causes some motion blur known as interlacing. To remove this blur, digital video editing programs such as Premiere Pro have a feature called deinterlacing, which either blends these two pictures together or removes one.
Open Premiere Pro and your video project. Drag the footage that you wish to deinterlace, and drop it into the timeline on Premiere Pro.
Select the clip on the timeline and select "Clip" from the top menu, then "Video Options" then "Field Options." This will open the Field Options Window.
Select "Flicker Removal" from the list of options if your clip is short and without much motion. This will blend every two pictures together into 1 frame per second. This is a fairly quick process but might result in unnatural looking images if there is motion.
Select "Always Deinterlace" if you would like to convert your footage to progressive scan. This will sort through the 50 frames per second from your camera and remove 25 of the frames that you don't need. This process takes a little longer but most likely produces a higher quality image, especially if there is motion in your footage.
Click "OK" and wait for the process to complete. Repeat for any other clips that need to be deinterlaced.
Deinterlacing is only necessary if your camera has interlaced the footage in the first place. Check your camera to see how it records images.
