Re: OT: Go Pro

[Daniel J. Matyola]

I am resending my reply to Ken, as I received a warning from the
server that my message was too long.

For the whales and the surfers I rely mostly on my K-5 II S and the
70-300 zoom.  I would use the GoPro more for filming the sail to and
from the harbor and the views of the mountains and other islands we
will be passing.  If I take a flight to Kilauea on the Big Island, I
would also use it aloft to capture "the experience," although I would
rely on my DSLR for images of the flowing lava.

When the camera arrived, I ordered two high capacity high speed micro
SD cards to use exclusively with the GoPro.  They came yesterday, so I
put one in the camera, charged the battery and took it with me in the
car.  As an experiment. I placed it on a non-skid tray on my dashboard
and turned it on.  I didn't even check the settings, let alone change
any of them.  I left it on during my drive home.

When I got home, I placed the card in the adapter, stuck it in my
MacAir, and clicked on what looked to be the appropriate file.  It
certainly exceeded my expectations.  There was a lot of noise, but
then, it was totally dark except for the street lights, stop lights,
and taillights and headlights of other cars.  I could easily read the
road signs and the major landmarks on my way home, and it pretty much
recorded the trip and did a much better job than any other video
recorder I have used.  I tried it in reverse on my way to work in the
morning, but I haven't yet had an opportunity to check out the result.

Dan I think you'll be out of range with the Go Pro if unless your going to 
be up close and personal with the whales and surfers.

Thanks for you comments, David.

There undoubtedly are annoying videos out there done with the GoPro,
but probably no more than are made with any other camera or video
camera.

You said you don't know what you would like to achieve with it.  The
best GoPro videos I have seen are ones that capture an experience, for
example sky diving, dirt bike racing or ski jumping.  There are
several activities I enjoy that I would like to capture digitally, but
I feel would not be suited for my M-5 II S.  In 11 days, we leave for
a month on Maui.  While there, I do some snorkeling and scuba diving.
Although I have a film underwater camera and a digital one, I have
never been able to capture the experience adequately.  I also will
swim with sea turtles once or twice out there, another event I believe
may be suited for the GoPro.  While I certainly intend to use my
Pentax DSLR on whale watches, since the action is sometimes extended,
that is another time I intend to try the GoPro.  I would like to take
some decent videos of the surfers and wind surfers at Ho'okipa.  Once
or twice a week I will rise early to paddle with the Kihei Canoe Club.
We often see whales, dolphins and turtles out on the Pacific, but with
the paddle in my hands, a camera I can strap to my chest or head would
be quite convenient.  The waterproof case is also a big positive for
me.

I don't really see it as replacing any of the DSLR shooting I expect
to do, but I hope it will add another dimension to my efforts to
capture the beauty and the spirit of a place I love.

All LCD and LED  and Plasma TVs display progressive images - they
convert on the fly in real time to progressive as you view. For web
viewing any interlaced footage needs to be converted into progressive
footage otherwise you will see nasty horizontal artifacts on any moving
images. So it may be as well to shoot progressive (eg 1080p) with the
gopro as you will no doubt want to share the video for viewing on
computers or other LCD screens. Shooting at 720p is another option, less
resolution but for web viewing, not a problem.


That's interesting but it makes me wonder why we'd ever shoot interlaced 
if all the end use nowadays is progressive.



Note that there are settings for 'wide, medium, narrow' and these relate
to field of view. The gopro lens is fixed and cannot be zoomed, except
by this method. So if the image is too wide for your taste or needs, set
to medium for a less distorted image.


Knowing nothing about Gopro cameras, this is also interesting to me. 
Only because I see so much footage that annoys me because of a fisheye 
effect.  Do the narrower views eliminate the distortion or just reduce 
it?


FWIW a lot of other companies are coming out with action cameras now, eg 
Shimano and Garmin.  I'm not sure if Contour is still around.  It's good 
to see some more companies getting involved.


I wouldn't mind playing with one of these things but when I think a bit 
more seriously I just don't know what I'd want to achieve with it.

Re: OT: Go Pro

[Daniel J. Matyola]

Sorry for the brain fart.

Here is the story:

Storm Damages Canoes and Beach at Kihei Canoe Club

Last night’s storm wrecked havoc at Ka Lae Pohaku Beach, home of Kihei
Canoe Club.  The heavy rain and winds combined with unexpectedly high
surf and a high tide to cause extensive damage at the club site.  The
nearby river overran its retaining walls and spilled down South Kihei
Road adding momentum to the forces of nature.  The beach eroded under
the club’s line of canoes, causing the front ends to pitch down at
steep angles.  The high surf, filled with debris from the river
runoff, caused the canoes to smash against each other.  One of the
club’s newest canoes, the Lele Mama, was swept out to sea, only to be
violently returned as a battering ram in the pounding surf. Another of
our canoes, Hoku wela wela is missing and presumed lost.  Emergency
calls and tweets went out starting at 4am and the club’s members
rushed to the beach to salvage and protect what they could.  “Our
canoes are the most precious resource of our club, they are like
family members” says Casey Logsdon, Vice President of Kihei Canoe Club
and Head Coach for Baldwin High School’s Paddling team.  “The losses
we sustained last night will take a long time to overcome. Both Maui
High and Baldwin practice from this beach, and we are right in the
middle of the High School paddling season.  The beach in it’s current
state is dangerous and unusable. We lost several canoes to damage, and
more amas and the iako’s that lash them together.  It’s going to be
very difficult to find the resources to keep the kids on the water for
the rest of the season.”

The run down on the canoe damages is:

Rockets - Hoku Wela Wela lost, Helu Ekahi and Kaohelo badly damaged
Malias (used in double hulls) - Pakalana and Miki Ala badly damaged,
Pulelehua moderately damaged
Bradley Encore - Hoku Ao moderate damage
Mirages - Lelemama severely damaged and possibly unrepairable
Amas - 2 missing, 1 broken in half, 1 broken nearly in half
Iakos - 2 missing, 2 broken

Fortunately, we did not have significant damage to our Force Five,
Bradley Racers, Strikers, Lightnings or light weight Malia hulls.
Pictures are already appearing on the club's Facebook group page which
show missing manus, smashed manus, cracks, broken tail and noses,
broken seats, etc.  We post more as we get them.

Kihei Canoe Club is asking our members to help raise money to begin
the restoration of these beautiful va`as. We have created a Donation
button on our website which you can use to make a donation to help.
Any amount you can spare will be appreciated. Mahalo in advance for
your help!!!

If you have a Mac, 'Compressor' is a very good way of converting. 50 bucks.

I use it constantly.



You don't need to have any editing software installed, you simply drag
and drop the video file you want to encode, choose the output type -
either many supplied presets or fully customisable - and off you go.

For instance, I output my video as high res files from my editing
software (FCP) but to send huge files of several GB each to a client is
wasteful and a bore. So into Compressor to quickly turn it into (say) an
MP4 file for sending by email or WeTransfer. HD full res video takes up
a lot of space, and for simple assessment viewing, a smaller (say)
960X540 MP4 file is much better. Some clients using for web will readily
take this size as final delivery! The encoding is first rate and very
quick, depending on computing power. On a 4 yr old MacBook Pro it
typically takes a me 90 seconds per video minute of 1920X1080 full res
QT movie to pop out a web-ready MP4.

Another indispensable app for video is Mpeg Streamclip (Mac and Windows)
brilliant converter, well worth having. If you use a GoPro, you'll have
to convert your files from the recorded MP4 to an editing codec like a
Mov before bringing them into your editing software. Mpeg Streamclip
does it very well and very quickly. And the best part - it's free.

I dare not look for first-person videos of ski-jumping as I'd probably need a 
change of trousers.  Although I do enjoy videos of wingsuits and occasionally 
downhill mountain biking (the scary stuff, eg Red Bull Rampage or urban 
downhill races).

One of the pro cycling teams made a video of the final minutes of a stage, 
filmed using onboard Shimano cameras.  That was fairly scary too.

For me, the only time I've wished for a video camera was when snorkelling 
around a coral reef during our honeymoon.  Otherwise I'd just be taking boring 
footage of running, biking and maybe open-water swimming.

I have given thought to making a film about training and racing but it'd be 
well beyond my skill and budget to produce to my satisfaction.

Re: OT: Go Pro

You should just shoot progressive (30p or 60p) unless you really know
what you are doing as converting 1080 60i to 30p can be kind of a pain
in the rear. People shoot interlaced by choice still because they can
render it out at 60p with a slight loss in vertical resolution. A lot
of cameras (video and dslr) only have 60i as the maximum frame rate.
For fast movement it is smoother. Its also the NTSC broadcast standard
which most TVs interpolate into 60-120p. A lot of it comes down to
what kind of look you want. 24p is kind of jittery with hard pans and
fast camera movement but can look nice if used in a cinematic way with
careful camera movements.

Regarding lens correctionslightroom now has the ability to render
video itself and apply some slight corrections. I wonder if it also
does lens correctionshmmm. I'll have to check that out. Their
export video function works well for the quick and dirty.

Yes the narrower fields of view remove some of the distortion and can
look much better. Typically if I am filming 2 people in the front seat

Not quite correct when talking to a US-based list member.

In the US, there are two  different formats used for broadcast HD TV;
720p (1280 x 720 progressive), and 1080i (1920 x 1080 interlaced).
(IIRC CBS broadcasts in 1080i, while ABC & NBC decided to use 720p)

Re: OT: Go Pro

[Daniel J. Matyola]

Thanks for you comments, David.

There undoubtedly are annoying videos out there done with the GoPro,
but probably no more than are made with any other camera or video
camera.

You said you don't know what you would like to achieve with it.  The
best GoPro videos I have seen are ones that capture an experience, for
example sky diving, dirt bike racing or ski jumping.  There are
several activities I enjoy that I would like to capture digitally, but
I feel would not be suited for my M-5 II S.  In 11 days, we leave for
a month on Maui.  While there, I do some snorkeling and scuba diving.
Although I have a film underwater camera and a digital one, I have
never been able to capture the experience adequately.  I also will
swim with sea turtles once or twice out there, another event I believe
may be suited for the GoPro.  While I certainly intend to use my
Pentax DSLR on whale watches, since the action is sometimes extended,
that is another time I intend to try the GoPro.  I would like to take
some decent videos of the surfers and wind surfers at Ho'okipa.  Once
or twice a week I will rise early to paddle with the Kihei Canoe Club.
We often see whales, dolphins and turtles out on the Pacific, but with
the paddle in my hands, a camera I can strap to my chest or head would
be quite convenient.  The waterproof case is also a big positive for
me.

I don't really see it as replacing any of the DSLR shooting I expect
to do, but I hope it will add another dimension to my efforts to
capture the beauty and the spirit of a place I love.

That's interesting but it makes me wonder why we'd ever shoot interlaced if all 
the end use nowadays is progressive.

Knowing nothing about Gopro cameras, this is also interesting to me.  Only 
because I see so much footage that annoys me because of a fisheye effect.  Do 
the narrower views eliminate the distortion or just reduce it?

FWIW a lot of other companies are coming out with action cameras now, eg 
Shimano and Garmin.  I'm not sure if Contour is still around.  It's good to see 
some more companies getting involved.

I wouldn't mind playing with one of these things but when I think a bit more 
seriously I just don't know what I'd want to achieve with it.

Dave

Incidentally, as far as accessories go, the GoPro branded  bits are

mount. Instead, I have several of the Delkin mounts and they are
absolutely bullet-proof:

The GoPro does not support ATSC, so moot in this thread.

I got that slightly wrong - 24p would equate to 48i and so on.

In the UK (PAL) we shoot 25p and 50i. 50i = 50 fields interlaced = 25
frames per second.

I know, it's confusing :)


Speaking of 24i, - I'd say you have 48 separate half-images:
24 images with only even lines, and 24 images with only odd lines.


I am not an expert, but in my understanding, the correct[ed] statement 
would be as follows:
48i would be somewhat similar in quality to 24p, while 24p is slightly 
better (resolution-wise) for [quasi-]static images, and 48i would be 
better for dynamic scenes (e.g. sports).


I think this short write-up covers the different frame rates+scan type
combination in a practically reasonable fashion:

not quite, there is analog video which was/is NTSC  and there is digital

which can be one of  many formats either interlaced or progressive at

and frame rates.

Set the thing up properly first - go into the menus (link up the gopro
wifi to an iphone preferably, much easier to make the changes on a menu-
driven app rather than pressing buttons on gopro).

For starters, you're NTSC, so make sure it is switched to NTSC and not PAL.

You're shooting video on the kayaks and canoes? if stills, hit the
largest res and go. If video, select a resolution that suits your end
viewing requirements. Most will shoot 1920X1080 which is High
Definition. Note that you can always down-size later for a more
comfortable web-viewing size. In the USA your standard frame rate will
be 29.97 or 30fps.



A brief description of interlaced and progressive video:



24p will produce 24 separate images in one second of video. 24i will
produce 24 frames of 2-fields each = 48 separate images in one second of
video. The 24p will be a bit more 'jittery' giving a film-like look. 24i
will be a smoother 'video' look.

In broadcast TV all material is shot in interlaced (hence 1080i) and
broadcast interlaced. Cathode ray tube TVs display interlaced images.
All LCD and LED  and Plasma TVs display progressive images - they
convert on the fly in real time to progressive as you view. For web
viewing any interlaced footage needs to be converted into progressive
footage otherwise you will see nasty horizontal artifacts on any moving
images. So it may be as well to shoot progressive (eg 1080p) with the
gopro as you will no doubt want to share the video for viewing on
computers or other LCD screens. Shooting at 720p is another option, less
resolution but for web viewing, not a problem.

Note that there are settings for 'wide, medium, narrow' and these relate
to field of view. The gopro lens is fixed and cannot be zoomed, except
by this method. So if the image is too wide for your taste or needs, set
to medium for a less distorted image.

Otherwise, attach it securely and hit record :-)

Note that the gopro will readily sink if it gets knocked off the kayak
etc. Unless you buh and attach a 'floaty back door' or similar. Or run a
lanyard through the mount and tie off to the kayak.

They are amazing fun and you'll have a blast.

Set the thing up properly first - go into the menus (link up the gopro
wifi to an iphone preferably, much easier to make the changes on a menu-
driven app rather than pressing buttons on gopro).

For starters, you're NTSC, so make sure it is switched to NTSC and not PAL.

You're shooting video on the kayaks and canoes? if stills, hit the
largest res and go. If video, select a resolution that suits your end
viewing requirements. Most will shoot 1920X1080 which is High
Definition. Note that you can always down-size later for a more
comfortable web-viewing size. In the USA your standard frame rate will
be 29.97 or 30fps.

OT: Go Pro

[Daniel J. Matyola]

I have acquired a used Go Pro Hero 3.  I intend to use it for certain
parts of my winter trip to Maui, such a Kayaking and Outrigger Canoe
trips and drive up the mountain.  I thought it might also be useful
this spring, when we are venturing off to Japan, with a brief stop in
China.

Does or has anyone on list use/used a Go Pro camera?  Is so, what have
you sued it for, and what do you like and dislike about it?

Any tips about how to use and operate it to advantage would be appreciated.
