Thread: 720p or 1080i?

  1. #1

    Default 720p or 1080i?

    Hi guys...

    I am still thinking about this problem.
    I can record videos with mam camcorde in resolution :
    720p (1280x720 @ 50p fps)
    1080i (1920x1080 @ 25 fps?)

    To this moment I recorded only in 720p, because I think it has smoother screen and better quality. And also I think it will be better to slow motion (and it is, or no? )

    Just need to know your opinion. Is 1080i better for normal non-slow motion clips if 25fps is smooth too?

    I would go with the 720p if theres alot of movement. Higher frame rate will give you sharper movement compared to the 25fps.

    Keep in mind some camcorders are 720p native and if you choose there 1080i setting, it only up converts your image so you wont have that TRUE 1080p anyways.

    I am stilll trying to get my head around the progressive and interlaced theory behind these settings. i have noticed that 720p at 60 fps can be used through apples cimema tools to get a good reduced frame rate effect where as interlaced material is not good for converting to a lower speed.

    Okay I just had a very informative lesson today, interlaced or i has 2 fields ( upper and lower field) and is how the frame is scanned. so in 1 frame it will have been scanned twice,.... which in 25fps will give 50 fields total in 1 second. Progressive is much smoother as you only get 1 field on each frame making the experience smoother. Interlaced material is jagged on the edges in some cases where p or progressive material will be much sharper. Don't let lower numbers fool oyu into thinking that it is a lower quality. Much depends on what you want to shoot will determine what setting you will want to use......and when.
