Understanding Interlaced and Progressive Recording on Pocket Camcorders
Many pocket camcorders today come with interconnectivity features that allow them to display and interact with HD TVs. There are many companies that develop and make camcorders and in particular pocket camcorders. Sony is one such manufacturer with several camcorder types including the camera series which is helpful for those bloggers use bloggy networks and want to show their photo conveniently. There are some ways that recording video and images on a pocket camcorder uses similar technology to that of an HDTV.
Most pocket camcorders record their video in 1080p, 1080i or 720p. The “i” suffix symbolizes interlaced scanning or recording, while the “p” symbolizes progressive scanning. Interlaced scanning and progressive scanning have both been used on a number of media electronics including DVD players, TVs and other media boxes. Interlaced scanning/recording is actually video that is uncompressed and then put together to create a complete picture whereas progressive scanning/recording employs a whole sequence that creates a complete canvas picture, this means that the video is made as is. Most times, progressive recording is good for recording, the standard is widely adopted by many major film production companies that use the 24p (24 frames per second progressive recording), interlaced recording is often the better of the two although in some cases, it is not ideal because the content or recorded video must be deinterlaced or put together before it can be played back. On the other hand, progressive recorded content does not require this and can easily adopt up scaling to a higher resolution without causing any distortion to the images or video.
On average, pocket camcorders will record at least 30 frames per second, although interlaced recording is higher at 60 frames per second. The frames don’t really matter much although the higher frame rate can sometimes mean more content captured. These figures are not often quoted on the pocket camcorder but you can find the information on the manufacturer’s website or on the pocket camcorder box.
Most HDTVs today support the progressive scanning technology although there are a few HDTVs that also support the interlaced scanning technology as well. For the avid fast paced camcorder taker, a pocket camcorder that supports the interlaced scanning medium is probably the way to go. For a more ametuer or new camcorder user, the progressive recording capable pocket camcorder is ideal. It all depends on your unique requirements.
