GH1 quality on big screen TV.

Another thing is about the playback and image quality of the 1080p 24 frames. Do any of you guys think the GH1 records nicely? I've probably asked before, can't remember. Most samples and videos off Vimeo and Youtube seem to be 720p. Seems like no one likes 1080p on GH1?
 
It should look just fine on the big screen. DVX films look good on the big screen, HVX projected footage looks great on the big screen.

If you have a 24" monitor on a desk at normal distance when you sit working it's probably covering more of your field of vision than most seats in a cinema theatre.

I use the "cow horns" technique to gauge relative viewing distance; hold your hand up making the Texas Longhorns "steer" symbol (pinkie and index finger sticking out to the sides). Then hold your arm out as far as you can in front of you, and see how many "cow horns" it takes to cover the screen.

In the theater, at normal viewing distances, it's usually two to three cow horns.

On my 24" monitor, at normal distance, it's two and a half cow horns. Sitting back in the chair, it's two. That's the same size as my 67" DLP TV in my living room, when sitting on the couch 10 feet away.

So what Martti is saying is, if you have a 24" screen, you're effectively seeing what your footage would look like when projected on "the big screen" (from a reasonable viewing distance).

I do. http://vimeo.com/6997918 - 1920x1080 Quicktime available for download if you are a Vimeo member.

Lucky I said 'normal' distance. If I do this I touch the screen just like Phil Collins. But then again I never sit further back than 5th row in cinemas.

Seems no one that doesn't use the GH1 likes 1080p, and most of us that do keep saying it's beautiful most of the time.
 
Wow. Nice job Martti. Really nice quality. =-]
Do I need some sort of downloader? When I click on download on vimeo, it just plays back the video.
 
Okay, if I have to be the one to say it, I'll say it:
I don't like the 1080 mode on the GH1 when shooting forests. There. I said it. For anything else, it seems pretty good, but a wide shot of a forest -- nope. Unless maybe it's a static shot, but if it's a moving pan in a forest, the GH1 1080 mode just ain't good enough. In my opinion. Your mileage may vary.

For anything else, it's almost always perfectly acceptable and I use it almost always in 1080 mode.
 
Agreed on the forrest - when doing a wide shot with a deep depth of field. For that use a good camcorder and then make the short DOF medium and close-up shots with the GH1. Ditto for a ocean or lake background.

Thanks. As I said in my first post in this thread - if you join as a free Vimeo member you can download most clips - unless the film maker don't allow it. You have more info about the spot here: http://www.dvxuser.com/V6/showthread.php?t=186392

Bitrates are not so easily comparable like that. It seems like the 7D's image is as compressed/poorly downscaled (IMO) as the GH1, it just doesn't break down with movement.

Here we go again... :)

Objectively, technically speaking, the 7D's image is less compressed (because of the higher bitrate) but more poor down-scaled (because of lower effective resolution and worse-looking aliasing) than the GH1's. You may call that a mere semantic difference, but it does effect how you use the cameras.
 
Hey Barry, what happens to the shot if you pan in the forest?? Really curious. Is it only the forest?

I just finished my script and it's a romantic comedy, with not much action. Maybe a pan, here and there, but nothing crazy. I'm just worried about it not looking decent when projected onto theatre screens.

Before the trolls rush in from the forests to scare you; have you seen dvbrother aka Todd Norris trailer for the short he's working on? Sounds like it's a good reference for you and the film you want to make.

my family owns a citrus and avocado ranch north of san diego, and i've been taking footage all around, and i havent noticed any of the "crapola" thats being mentioned here....sorry Barry...
i do, however, control my shots, and i have shot in 1080/24p, as well as the 720p settings....just not seeing it. trees/leaves/complex landscape everywhere....is there harm in controled shots?....seems to be working fine for me.
 
How much editing or viewing on a larger screen have you started to do, Skinny? I did some stuff in the jungle a couple of weeks ago, and I thought it looked fine until I started really messing with it, then the mud became apparent. However, I was able to get useable video out of most it, but it does take a hit.

On the original topic, I tried plugging my GH1 directly into an HDTV (something I hadn't done) and for whatever reason it looks terrible in comparison to importing the footage into the computer. I think we're used to an Hv30 or something giving really amazing quality plugged into a T.V, but this seems like the wrong route to go for the GH1!
 
Hi Kellar, is it with all your videos from the GH1 that look terrible when directly plugged into the HDTV?

well, i suppose i could have been more specific, but my exprience is along the lines of your response...thing is, for the most part, i don't "mess" with my footage too much. but when i do, it's usually with the intent of seeing how FAR i could push it, since i haven't been editing gh1 footage for long. I came from Canon xha1 hdv footage that was somewhat of a nightmare at times.

at no point was i implying that my footage is always perfect, and i apologize for my poor phrasing. i am becoming aware of the limitations with the gh1's footage, and i've been paying a lot of attention to these boards for insight. i've just been fortunate thusfar, as i don't have all the professional tools that some people have.
