recorded with interlaced scanning, you’ll see a flickering between fields, similar to the VCR flicker when pausing a VHS tape. Usually, consumer camcorders record at 60i, which means 60 frames-per-second with interlaced scanning. This is actually 60 fields per second, which when interlocked create 30 frames-per-second.
In progressive scanning, the two fields of resolution that make up each frame are captured together at the same time, sort of similar to film in that a series of still images is recorded in sequence. While a minute of video recorded at 30p (30 frames progressive scan) would contain approximately the same amount of data as a minute of video recorded at 60i, there are slight differences. In general, progressive scanning rates produce motion that is more similar to the way film does, although interlaced scan produces slightly less smooth motion. Both
