IMO the audio is not at all "professional". You'll get lots of handling noise and no way to set audio limits. If you put on a tripod or don't have to touch it and you're in a quiet room with no background noise then it's fine. A little hollow sounding to my ears but definitely usable. Just do a GF1 search on vimeo and you'll find plenty of videos where you can hear the mic.
GF1 testing and footage goes HERE

How are you getting 23.975 fps on a GF1?
I wanted to really put the manual video controls to the test so I filmed my son skateboarding last night. The over head lights make it very difficult to get accurate exposure and color. The manual controls were essential in getting these shots.

For 720p I think they look great. I used pretty much every lens I own. Those lenses include the 20mm F1.7, 45-200mm, Nikon 30mm F1.4, Canon 55mm F1.2, and the mighty Nikon 85mm F1.8. The Nikon lens was used for most of the really close up shots and it seems to give the sharpest most contrasty image of all of the lenses. It is hard to hold still without IS though.

Hi to everyone!
Im owner of GF1 and new to this forum.
At the beginning I want to thanks to all hacker and testers on this forum.
Then to user MPGXSCVCD ... I learned a lot from your tutorial and videos (especialy on last manual lenses review).
Now I want to say that I also applied lpowell "Reliable In-Camera Playback Patch" and its stable in MJPEG with 35 Mbps but on AVCHD only around 22 Mbps. Same as user Long Rob.
Does anyone knows is this maximum bitrate on AVCHD with camera playback or we could managed to get higher? I didn't do any special testing on bitrate since Im new but I will do in future.
And it would be great if we could have separated thread with GF1's settings.

AVCHD is a variable bitrate codec that will seek to minimize file size rather than maximize image quality. The Reliable In-Camera Playback Patch sets a maximum AVCHD bitrate of 44Mbps and in practice will average around 40Mbps on sharp-focus, well-lit, highly detailed scenes. If any of those three conditions are not met, you'll likely see bitrates around 24Mbps. In such cases, high bitrate MJPEG encoding will often produce higher quality images.
In addition to the Reliable In-Camera Playback Patch, I've developed a Fast Action 3-Frame GOP Patch that can produce videos with higher maximum bitrates. These patches work equally well on both GH1 and GF1 cameras and are switchable between NTSC and PAL modes. Here's a link to downloadable PTool INI files containing these patches:

Nice video, my favorite of yours so far. Though I did wince every time your little guy hit the ground.
2 questions:
1. In your comments you mention turning sharpness up 60%, I'm assuming in Final Cut? I don't tend to sharpen my GF13 videos up (and I set the sharpness to -2 in-camera), so this is interesting for me. I've played with sharpening in FCP but never liked the effect much above 10%, however your video looks very good with quite a lot of sharpening, so how do you do it without the image getting all glazy?
2. Handheld or stabilized? Either way, very impressive.

try the unsharp mask filter instead of the sharpen filter. keep the settings real low, like 50 - 1 - 0 and you get some good results. stack up a couple of filters, with the middle number changed. when you change the middle setting, you are adjusting the radius of the mask, so adjusting the local contrast within that size an area. (i think, correct me someone if i'm not 100% accurate)
Thanks for the comments. Yea it was hard to watch him take on those big ramps. He is a tough little kid though. He wouldn't back down until he got it. I almost wish he would stick to rock climbing. It is a much safer sport.
I use a very simplistic video editor called AVS video editor. It does everything I need. Including some decent sharpening. My next demo video will show the affects of this sharpening. I also turn the sharpness up all the way in camera as well. However, I am not sure if that is the best practice yet. I need to do some more experimenting.
My videos are all shot hand held with manual focus lenses with the exception of the 45-200mm lens that I just got for this video. A lot of the clips from that video were shot with the 45-200mm and the IS on. However, they were all hand held which is not easy to do even with the in lens IS.
Just want to say thank you for your work. It is very much appreciated. You have done almost as much for my GF1 as Vitaliy has. And that is saying a lot.
Thanks for the tip, I use unsharp mask all the time in Photoshop, but I've never really played with it for video. I never like the way sharpening looks when I apply it to my own videos, but for some reason it looks fine to me when watching someone else's video whether it's Phil Bloom's or the ones you guys post. I think it's that mechanism whereby when you know what the material looks like without artifacts it's hard not to be bothered by them, whereas if all you ever get to see is someone's finished product and it's been sharpened/graded/who knows what, you're not privy to what it looked like unprocessed so you accept it as a whole. So what I need is a trained monkey to come in and take my camera from me after I'm done shooting, import the footage to my Mac, sharpen and grade it, export, and then send me the link when he's done. I don't want to know what he did to my footage. I'm not paying the monkey good money to involve me in the process, except to flatter me as one of his "cool clients". I just want him to make it look good and not bother me with the details.
Maybe this is called in-camera sharpening..

Wow, AVS Editor. AVS Editor....now that's a name I haven't heard in a long time. A long time.
We take opposite approaches to GF1 video shooting. I turn sharpening down all the way in camera and don't use it in post. Ive never had good luck sharpening video, i always regret it when watching it later after its been baked in. But your video looks fine to me. I need to play with sharpening some more. Not that I feel my stuff is soft, but I'd like to know how to master the effect in the event it's called for someday.
And I'm really glad my little guy prefers drawing to skateboarding. I have enough grey hairs as it is.

we all need a trained monkey sometimes... they are known as assistants in the industry lol
i think it's important to think of what the audience 'sees' and not what you see when processing your video footage.
does the audience care that you took 5 days to get one shot. no, they wont even know unless you tell them - either in voice over or by setup - so this applies to sharpening, color grading, natural looking effects etc.
does the audience see that the image is sharp, yes - do they care about a tiny bit of artifacts after sharpening when the whole image has artifacts from youtube, vimeo, broadcast, projection (dust etc)...
i find it really useful to do an effect like sharpening till the point where it just bordering on bothering me, then i reduce it till it doesn't and then step away from it for a night. do something else, cut, color grade some other images, or just go out and forget about it. when you look at it in the morning, you'll know if you have pushed it too far.

Here's the link to my Anamorphic 1920x810 MJPEG Patch. It works on both GH1 and GF1 cameras:

I think the key to sharpening is to only sharpen in certain situations. If you are using a wide aperture lens and the majority of the picture is out of focus sharpening isn't going to do much. However, if you are filming in a well lit place and you are focused in tightly and accurately sharpening can make a huge difference. I use it more with skateboarding(outside) than I do with the indoor rock climbing.
ok, so i have finally been able to take the camera underwater and test it in the field. in a real world scenario, it worked perfectly! and the results are incredibly good.

Yes and no.
LPowell figured out a PTool patch setting that lets a hacked GF1 shoot high bitrate MJPEG at 1920x810. When you take this footage and conform it to a 1080p timeline, it becomes 1080p. It's not strictly speaking virgin 1080p but it looks pretty damn good, without significant artifacts.
The impetus behind the patch was to enable cropping this stretched footage by 12.5% top and bottom to achieve an anamorphic Cinerama frame. I've played with it and it's pretty nutty how kosher it looks -- anamorphic HD Cinerama from a relatively cheap camera marketed to Japanese girls.
But certainly you can leave the stretched footage uncropped if you want 1080p. I shoot NTSC but I'm sure PAL's fine too.

Well done, that looks fantastic. What housing did you use? I'm too much of a fatalist to take my GF1 underwater. Chicken, I think is the clinical term.
