| MikeB said: @ redspear DirectTV now does 1080P albeit heavily compressed. TBH even fewer people will recognize the diffence between 1080i and 1080P and most HDTVs being sold are still 720P so it is null point anyhow. 1080p downscaled to 768 lines can make a good difference compared to 1080i being upscaled (540 lines per frame). |
All those people who shoot documentries with Cannon XH-A1s and other similiar cameras that use HDV tape should really keep that in mind I guess since they only record in 1080i. How can so many people who work wiht this stuff be so wrong.Chances are you ahve seen some of this stuff on HDTV and never even knew(BTW the canon even does a trick with green CCD to achieve 1080i ).
Seriously resolution is the least important of the big factors that matter for image quality while higher resolution is nice and having lossless compression really matters(for video mastering) A lossy codec does not viewing. If you work with codecs at all you would understand that what lossy means is that it is mathematically impossible to recover the original format after compression andas such any attempt to transcode would result in a loss of image. Some lossy codecs look almost as good as the lossless and some lossless codecs look a lot worse. What you are reffering to is that the bit rate is low and hte image suffers from that and I agree.
And most of this is mute anyways as long as people watch video on TVs with filtered light they lose both colorscale and image quality.
RED save us now and release that EPIC 261 MP video sensor for $55K.
BTW it is nice to work in higher rez especially if you are going to stabilize and crop add masks and effects and composite images and then downsize the image.
Stop reading the companies PR books head out and actually work with this stuff once in a while. Learn about HDR and DoF and lighting. Understand what a gamut is and look at a reference monitor(trust me htey look like they are from the 80s but the picture quality beats any HDTV or LCD I have seen today by far.
