Is there something wrong with the camera or is there a setting that can be turned on or off to get rid of this. This video shows it alot. Look at the trees and how everytime the camera pan kind of stops the trees come into focus. But once the pan starts again the trees are blurry? I cant figure it out.

And in this video as well. You can really see it on both images. Now clip on the right has the Mercalli video stabilization filter and you can really see how the original image is very blurry with the camera movement.

I noticed in other videos I watched, the the focus of the HF100 looks a little off to me so this might be the problem but im not sure. Even in low light it is clear. look at the flowers on the table. So its not just a day light thing!!! Is there any way to get rid of this????

Paul, Did u get a HF100?

Paul- 24p is always going to have an issue with panning and blurring. It's no different in true film. Cinematographers know this and directors of photography are well schooled in the art of SMPTE spec shooting. If you watch a movie in real film most camera shots are in lock down short static shots or in SLOW dolly moves at best. Of course there are many low quality films shot by shaky new age cinematographers but these all have the inherrent blurring.

aside from the art of shooting in 24p, you also can cause a technical issue with interlace field order or shall I say reverse order. This happens when you shoot in odd field first and then render your project in even field first. What this does is cause the fields to separate in a time delay that changes with the speed of the right to left pan. This is easily corrected in post. This has to do with the 1080i. Now with 1080p you don't have an issue with blurring by this cause especially at 60 p frames a sec. When you shoot 30 FPS you will see some minor stutter if your eye is sensitive to it. Most people don't see this at 24 fps, much less at 30 and certainly no one at 60. But frame rate is not a cause of this blurry on movement issue.

There are also artifacts of imager design manifesting in lag time and sensor decay. I would not be surprised if you could get specs that the consumer chips, evenm the new cmos ones have problems with image lag causing a blur when pixels are refreshed with different image color. A few years ago I got info on 3CCD imagers for a broadcast camera and a similar technology on an industrial one. Both were 3 CDD 2/3 inch imagers but the broadcast version was >$5000 and the Industrial one was just under $2k Lag time and alignment specs were much better on the broadcast spec imagers. Now consider the consumer imager.

NO

To be honest, I was being a Jerk. I came across this thread
http://www.avsforum.com/avs-vb/showthread.php?t=1010020

And realized that Luc was using my videos to help pollute the forum with his Anti sony SR11/12 propaganda.

He would never post that his beloved HF100 would produce the same results.

I just find it silly. So I decided to act just as lame-brained and post a pointless thread.

I made a bet with my friend that someone would come to the HF100/10 defense and say that the videos were not blurry but normal. Because this is exactly what we were trying to tell Luc.


Well I lost. No one came. I guess we are really past the turf war.

I owe someone a beer!

Hey Don,
thanks for taking the time to reply. These videos were shot at 60i.

But you bring up some good points. And one is that the Pro's use very slow camera movement.

I was thinking about this. Lets say I take some video using really slow, I mean really slow camera pans. I then speed up that video in post to the look of normal speed. would the finished product be a very sharp pan that looks natural?

I wonder why we notice the blurr created in a video more than we do in our real lives. Just moving my head and focus from one object to another creates a blurry pan. this is even true while driving in a car. If you focus on the stop sign you are comming up to everything else is in motion and blurry.

Perhaps it is because our eyes are focused at a fixed distance when we watch a tv or monitor. So it would only be normal to notice the blurry image in this plain.

Paul, I think part of it is in the encoding...any encoding. It's very tough for any of these processors to keep up with fine detail and relatively rapid movement at the same time. You can even see this with professional cameras.

A couple of years ago there was an article in one of the Cinematography issues that addressed the subject of human eye perception. Per the article author, The eye can capture up to about 35 FPS and beyond that the refresh rate will tend to register as a blur, less than that the images will strobe. The math works out nicely for a 59.94 ( 60p) frame rate for absolutely smooth motion and well adapted for fast pan sharpness. 29.97 ( 30p) not so good and 24p, careful attention needs to be adhered to for panning of the image will judder on the screen.
You may be able to experiment with a true 24P capable monitoe and a BluRay program that has some slow pans and fast pans. Test them at 24p, and 60 P output from your player and monitor. I have a BenQ W1000 I run in 24P for movies and 60P for video camera productions. Granted, most of my viewing is at 24P because that is what I watch.

What about a faster shutter speed, or am I missing something? Couldn't a person set a shutter priority, therefore cleaning up the action captured during movement?

My film photography is a little rusty ( haven't shot 16mm film since 1983) but a faster shutter speed for each frame would reduce the blur in each frame exposed but the frame rate still needs to be increased to improve the motion smoothness. motion smoothness increase reduces judder. Often the judder can be confused with the picture sharpness unless you know what you are looking at. In my opinion, I would select to increase shutter speed when the action in the shot is fast. I would choose to increase the frame rate when I require faster camera movement for my shooting art.

Thank you for clearing that up. I never noticed the difference before with my miniDV camcorder, maybe the benefit of being lower res :(

So If I select to shoot in 'sport' mode, theoretically speeding up the shutter, I still need to keep relatively slow pan for it to benefit the subject?

On the subject of camera motion, I just video'd a parade yesterday, and needed a stable, yet portable, roost. I connected my Manfrotto monopod underneath my shoulder stabilizer, basically giving myself a steering wheel. On that I connected my Panny SD9 and shot 40 minutes nonstop. The monopod allowed me to raise the camcorder high up on the air at times, and it's weight keep that movement from being too jerky.
Anyway, the Panny only warned me once that i was moving too fast, presumeably its gyro sensors didn't detect excessive motion vertically, so it was more forgiving in the horizontal.
