Hi,

I am on the brink of buying an EX1 - although, two conflicting articles are holding me back.

The first from;
http://provideocoalition.com/index.php/awilt/story/whither_the_hvx200/

'The EX1 has no standard-definition capability at all. You can shoot 50Hz or 60Hz formats, but they’re all HD formats. You can downconvert during playback, but the downconversion quality is poor...
If you’re using the EX1, you had better have an HD field monitor along. The lack of low-pass filtering in the EX1’s downconversion causes distressing amounts of aliasing in its SD outputs, and the cross-color artifacts in its composite output render it almost unusable (certainly you’d never let a client see it). Even the benefits of Y/C monitoring are unavailable for the EX1 since it lacks that low-cost, high-quality connection'

However; I then found this article;
http://www.kenstone.net/fcp_homepage/ex1_sd_output_young.html

'The Solution. Here's the workflow I use, I am working in PAL 25 fps: (1) Edit your EX1 footage as HD within Final Cut Pro - I also choose to Render in ProRes as this does away with most of the problems which have made editing long GOP in the past such a torturous experience. Any rendering that takes place uses ProRes, thus eliminating the need to conform the video while working...'

I am using FCP 6.0.5 - so editing ACHDV won't be problem. But the top article does concern me.

I will mostly be filming weddings - and although the rolling shutter issues are harder to replicate then some will you have you believe - downconverting a good quality SD image and having to haul around a HD field monitor along is not really selling it for me.

The first article you linked was done with a beta release of the camera. The EX1 actually outputs a lovely SD picture, you just can't RECORD to it on the camera, you have to record it with something off the camera.

The S-Video connection issue is also a non-starter. There is a cable that can be purchased that gives you s-video. I have one sitting on the desk in front of me, and it's what I use when I take my SD monitor in the field with me.

Get an EX1 in your hands. LOOK at the display. It's the best HD LCD on the market in this segment. You won't need a field monitor at ALL unless you are doing some very critical work.
