I stands for interlaced and p stands for progressive. Both these types of scanning are explained below. The scanning of the lines in each frame takes place from line A to line B. It jumps from A to B straight. Therefore is called progressive. In the interlaced scanning mode, the scanning of the lines in each frame takes place from A1 jumping over to B1 then to A2 before moving to B1 and then jumping to B2.
In other words, the lines are scanned alternately. Interlaced Video: Typical standard definition video is interlaced video, as is i. In interlaced video, your camcorder will record every other line of resolution. It starts by showing lines one, three, and five and then later follows with lines two, four, and six.
Progressive Scan Video: Progressive scan video records each line of video in order without skipping any lines. So, it would start first with line one and work its way all the way to line Progressive scan video typically looks better than its interlaced counterpart when it comes to fast-motion video like with sports.
Full HD is a marketing term that refers to camcorders that record in x resolution. It's a way to compress and save high definition video onto digital storage media like hard disk drives , and flash memory cards.
HD camcorders come in all shapes, sizes, and price points from all of the major camcorder manufacturers. In fact, a lot of today's smartphones are recording in p. This eliminates the need to even have a dedicated camcorder, especially if you don't need to record video for anything other than this or that event, or for fun.
Currently, there are consumer high-definition camcorders available that record video onto MiniDV tapes, mini-DVDs, hard drives, flash memory , and Blu-ray discs. While the higher quality video is definitely a plus, it also presents a few challenges. The biggest is where to store it. HD video files are much larger than standard-definition video files. Others will play it back, but slowly and with plenty of frustrating pauses.
Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content. Create a personalised content profile. That's not quite the full story but it will do for now. With p, all lines are captured at the same time.
There's some extra stuff happening behind the scenes with i60 that reduces interlacing artifacts but reduces resolution. So, p60 generally looks better than i The thing is, when HDTV was standardized, processing power and bandwidth weren't good enough to handle p60, so there is no guarantee it will work on all systems and no broadcasts support it.
On the other hand, computers and phones are all progressive scan, so interlaced formats look horrible on them. You can also do p at 24fps which is well supported but will need to be converted to i for broadcasts. What I generally do, since I mostly do television work, is shoot at p30 in a i60 CODEC , which produces a nice, clean image but reproduces well on i and p systems.
Really though, most people going for a "theatrical" look shoot at p
