Well, I've shot about 40 minutes with the camera so far, mostly on the Watercress Line (http://www.watercressline.co.uk/) in bright winter sunshine, and like any new relationship it's been a bit of an emotional roller-coaster ride. Happily, I've overcome the early misunderstandings, and the romance is blossoming!
The camera is way ahead of the rest of my technology (for the moment), so it has been quite difficult to appreciate what it can do, and what effect the various controls actually have. My computer and NLE are strictly DV-only, my TV is PAL 4:3 SD and though my DVD-recorder has a Firewire input, nothing has component, DVI or HDMI capabilities. Even my Internet connection is 56k dial-up, so I'll not be able to post any clips from my experiments - sorry. Maybe some DV-resolution frame grabs, when I get a few moments...
It's a real shame that the camera does not have an S-video output (feature request for the Mk2 version?). The composite picture is actually rather naff - at first I thought I needed new glasses! Happily, I can connect the Firewire lead to my DVD recorder, which has an S-video connection to the TV. This set-up shows that the XH-A1 produces really great DV images - better than my old XM1, and I still think that's pretty good. The broad black letterbox bars really complement the vibrant image. One hint - although my DVD recorder (or perhaps my TV) can detect that the signal is widescreen, and adds its own letterbox, the edges (especially the top edge) flicker - presumably with each field of the interlaced picture. This does not happen if you tell the camera to add the letterbox (in VCR Play, choose Letterbox from the Signal Setup menu). Also note that you can't change some of the settings in the Signal Setup menu, such as down-convert Y/N, when connected to a live Firewire device, but the manual doesn't tell you this, though it has been mentioned around here. Here's my drill:
-- connect Firewire cable with both devices off;
-- turn on XH-A1 in VCR mode;
-- select Signal Setup options;
-- switch on receiving device.
To see what the HDV output looks like, I took the camera to Oxford's branch of Curry's and plugged the component leads into a number of different "HD-Ready" LCD TVs. At first, I was rather under-whelmed. Part of the problem was that it was hard to get a suitable distance away from the screens, but even so, the picture was a bit blurred and not at all "special". I tried 26" and 32" Panasonic, Sony and Samsung models, priced between about £800 and £1000, but none impressed. The salesman (who was actually remarkably knowledgeable and helpful) agreed with me, but suggested we try the more expensive LG (just under £1200). This made a big difference - now the pictures really did look the way I'd hoped they would: bright, clear, realistic. I played through almost everything I'd taken on this TV, and even some views of a friend's vegetable allotment looked good, and I'm no fan of leeks and Brussels sprouts!
BTW, none of the HD-Ready TVs I saw there had anything like acceptable SD pictures, which is very sad, since we will still want to watch SD pictures as well as HD. The majority of broadcasting for the foreseeable future will be SD (here in the UK, at least), and many of us have archives of DVDs, mini-DV and even VHS. I really cannot see why anyone would buy an HD TV for normal use just at the moment.
To return to the camera; the pictures on the TV screen (whether SD or HD, CRT or LCD) are noticeably warmer than through the viewfinder or on the fold-out LCD. It seems to me that there is a very slight glow, which makes things like brickwork look very warm. I've been shooting in bright, low winter sunshine, so there is a bit of a yellow/orange cast to the light anyway, but shall we say that the camera is making the most of this effect? Don't get me wrong - I love it, and if I'd thought of it and dialled it into the camera myself, I'd be exceptionally proud of my efforts!
I'm also impressed with the auto exposure's abilities. I've shot several scenes back-to-back using first the auto setting, then switching to manual and bracketing slightly different iris settings, etc. In all "normal" situations, the auto was right on the button. When things get a little harder, the AE Shift gives good, predictable results, though I haven't had a situation yet where more than +/- 0.5 was needed. I was also pleased with how close the viewfinder and the image on screen match, at least in terms of exposure, though there is a little more shadow detail in the (PAL SD CRT) TV picture than in the viewfinder. Maybe I can change the viewfinder brightness or contrast... By the way, does anyone else think it's a shame that AE Shift is only available from the menu? Could it go on a thumb-wheel or even the custom keys (AE Shift + and AE Shift -)? Something else to add to the XH-A2 wish-list!
I've tried a couple of custom present settings. When the sun went in just before a train was due, I tried black-stretch and soft knee to counter the bright sky and rather dull foreground. I didn't manage to do back-to-back shots, and switching part way through the shot would have spoilt the shot, so I can't be sure, but it seemed to make a useful difference. After dark, I was shooting under station lights so added +6db gain and to counteract this tried +3 coring and low NR2 noise-reduction, as recommended in a previous DVi thread. Again, I didn't go through lots of experiments to test these settings, but there's almost no speckly noise in the dark areas - at least in the view finder and on my SD CRT TV.
A couple of things that I miss from the XM1 - neither very significant :
1) ND on/off reminder - especially since the viewfinder does not show the auto-selected shutter or iris settings;
2) 10 second count-down - I hadn't realised how much I use this for static cut-away shots and the like;
I'm sure they will be added to the XH-A2, along with everything else.
The more I use my XH-A1, the more I like it. Long may it continue!
