Coffee at mom's - Getting to know the Steadicam Merlin
4 months ago
I went to see my mom last Saturday - brought the Steadicam Merlin that I'm still learning to use. There's less pendulum effect in this footage - maybe because I'm walking around slower than in my forest footage: vimeo.com/831855
This was shot in 25p (PAL) TV mode (1/25) and AWB. I think, I need to use a faster shutter speed for moving shots - maybe something like 1/100 instead. I think that would have given me less blurriness.
The Steadicam Merlin is not a toy that instantly makes any footage look like a million dollar production - you need to practice with it for some time before you get to know it well.
If you don't mind the price, I can highly recommend it for any advanced user. By advanced, I mean someone with a good portion of patience and someone who's not expecting it to be perfect right out of the box :)

I agree that it takes a lot of practice. I have trouble with quick movement or directional changes.
For some reason this played back very choppy. I will download it and see if that makes a difference.
Nice job, you are getting better.
Does anybody know the answer?
And I agree with what you said. You should not expect this to work perfect right out of the box. The "cookbook" recipes Tiffen provides are merely a good starting point. But there is no magic formula that will work for everyone. My mentors always told me, "Practice makes Permanent."
I use Sony Vegas Platinum 8. I got to know Vegas by following Eugenia's tutorial:
eugenia.gnomefiles.org/2007/09/19/crash-course-on-sony-vegas/
and rendered it with her recommendations:
eugenia.gnomefiles.org/images/wmv.png (since I'm in Europe and use PAL, I used a setting for 25p instead).
I added some 'sharpness' in vegas too.
This is definitely much better!
Loved the up and down movements and the smooth 360º pans :)
Much improvement from your walk in the park vid.
Loved the smooth pans.
Congrats.
Maybe that's the difference you see.
Bout shutterspeed - clearly I do not know the answer, but I am wondering if not a longer shutter speed might actually "pleasantly" affect the image with motion in that it will get a bit of motion blur rather than a series of very hard images in the motion.? Guess what I am wondering if what would happen if you instead slowed the shutter...?
A shutter speed of 1/25 and a frame rate of 25 (since I'm on a PAL as opposed to NTSC) means that the camcorder records 'all the time'. If you set it to 1/12, you obviously will only get 12 frames pr. second - this makes the footage very choppy and blured.
If you use a shutter speed of 1/100 and a frame rate of 25, I guess it means that the camcorder takes an image at 1/100 of a second, then holds the shutter closed for a while and then takes another at 1/100. This should give you 25 frames that are not blurry, but I guess it will also leave out some information, since it's not recording 'all the time'.
Does that make sence? :)
I could be mistaken though.
From Bo's link, it's stated that the camcorder doesn't handle shutter speed with the shutter but rather with how it exposes the sensor. I'm guessing, it then records at 25fps but frame 1 and 2 (and so on) are added together to create an image that is brighter. This probably means that the sensor doesn't 'discharge' before it has recorded two frames.
Does that make any sence? :)
'Still cameras' are so much easier to understand :D - at least to me...
BUT - I get a bit fuzzy knowing that the same camera produces one image 30 times a second (basically in the us) however if that is true, the shutter can not possible be open for 1/12th of a second.. (it would only be able to make 12 images or less) so it seems that any shutterspeed lower than 1/30th on video is something other than shutter-speed.. honestly Im pretty confused about this, lots of cameras offers lower speeds though my SD2 don't just have a slow-shutter mode (same thing I guess)
interesting - did a search- and the answer seems to be that while shorter shutter speeds keeps the image sharper because it reduces motion blur - however motion blur ties the frames together better and reduces the feeling of stuttering a bit.

More technically, since the shutter opens, or activates, and lets light spill in on it for 1/15th of a second or 15 frames, assuming your shooting in 30fps, that period of a second is rendered as frames on your hdv tape.
Its easier to see then understand, if you set your camera on a tripod and put the lowest shutter speed on you will notice everything looks fine, but then quickly (not too quick) pan the tripod to the right you will notice the duration of the pan, the image will smear or blur. Once you let go and the tripod settles you will notice your stationary objects are clear and in sharp focus. turn up the shutter speed gradually and you will notice the image darkens (so you might want to add light) but your stationary objects blur less and less during the pan.
However, after our vacation together, I think she understood the 'concept' and she enjoys watching the videos from Canada.
She even told me that she thought the camcorder was a 'good investment' :) - that from a woman who's always telling me that I spent too much money on things I don't need (which is probably true)... :)
