Just wondering if anyone knows the shutter speeds of the GoPro3 Black Edition. I understand that it can record at 240 fps, but that's frames per second, not shutter speed during recording any type of video.

 

Please help if you can, thanks.

Here are some links :

Fast Shutter Speed, ISO and Aperture Numbers

Does not follow the 180 shutter rule. Much faster. Shutter (30 to 2,000?).

Thanks Jogiba.

 

Wow, such odd shutter speeds on the GoPro3 Black Edition.

 

I actually went and bought a Panasonic Lumix Lx7 on 11 29 2013, got it from B&H Photo Video on the following Monday.

 

I absolutely love my Lx7. I'm so glad and happy that I didn't get the Canon R400. That thing is a garbage compared to the Lx7.

 

They droped the price on the R400, to like $169.99, while I had no problem spending the $289.99 for the Lx7. It's worth every penny.

As far as I know virtually all affordable cameras (<$1000) with high speed video mode now offered use automatic exposure control (AEC) including the GoPro models. If you are interested in using high speed video for analysis of motion you want very fast shutter speeds and minimal motion blur. While people state that the shutter speed of AEC cameras are 'very fast' in direct sunlight nobody knows how fast the shutter speed is. It's impossible to determine likely shutter speed from the information available on the cameras - the specs often give the still shutter speed and there is no way to tell what applies to high speed video mode. You can get an idea by searching: camera model Youtube high speed video golf Examine motion blur.

I wanted to know the shutter speed/ motion blur of a typical low cost camera with high speed video mode and picked the Canon Powershot ELPH 110 HS / IXUS 125. Here are the test results.

http://www.kinovea.org/en/forum/viewtopic.php?pid=3059#p3059

It is very easy to test the camera under lighting conditions for minimum motion blur

Video a high speed object, golf swing, tennis serve, rotating object,.....
1) in direct sunlight
2) using the widest angle zoom lens setting.


If you test your Panasonic LX7 for motion blur please post.

Anyone else with a high speed video camera please test it and upload the videos to YT and post your test conditions in the above Kinovea thread or here.

If you are more interested in videos for entertainment at 30 fps playback, and not motion analysis, longer shutter speeds and more motion blur may make the videos look more attractive.

My LUMIX LX7 has FULL MANUAL control over Video & Photo, I absolutly love it, and is perfect for what I need it for. The LUMIX LX7 can shoot in AVCHD 1080 x 1920 @ 60 fps (1/30 - 1/20,000) shutter speed. That's right, 1/20,000.

 

Here, I wrote down every shutter speed for the LUMIX LX7.

 

 

AVCHD : PSH @ 60 FPS @ 1080 x 1920

Shutter Speeds @ F/1.4 ONLY ( Available in ALL ISO Modes )
30, 40, 50, 60, 80, 100, 125, 160, 200, 250, 320, 400, 500, 640, 800, 1000, 1300, 1600, 2000, 2500, 3200, 4000, 5000, 6400, 8000.

Shutter Speeds @ F/1.6 - F/8.0 ( ALL ISO )

MP4 : FHD @ 30 FPS @ 1080 x 1920.
Shutter Speeds @ F/1.4 - F/8.0 ( Available in ALL ISO Modes )
30, 40, 50, 60, 80, 100, 125, 160, 200, 250, 320, 400, 500, 640, 800, 1000, 1300, 1600, 2000, 2500, 3200, 4000, 5000, 6400, 8000, 10,000, 13,000, 16,000, 20,000


MANUAL PHOTO MODE : F1.4 - F/3.5

250", 200". 160", 125", 100", 80", 60", 50", 40", 30", 25", 20", 15" 13", 10", 8", 6", 5", 4", 3.2", 2.5", 2", 1.6", 1.3", 1", 1.3, 1.6, 2, 2.5, 3.2, 4, 5, 6, 8, 10, 13, 15, 20, 25, 30, 40, 50, 60, 80, 100, 125, 160, 200, 250, 320, 400, 500, 640, 800, 1000, 1300, 1600, 2000

 

MANUAL PHOTO MODE : F/4.0 - F/8.0

250", 200". 160", 125", 100", 80", 60", 50", 40", 30", 25", 20", 15" 13", 10", 8", 6", 5", 4", 3.2", 2.5", 2", 1.6", 1.3", 1", 1.3, 1.6, 2, 2.5, 3.2, 4, 5, 6, 8, 10, 13, 15, 20, 25, 30, 40, 50, 60, 80, 100, 125, 160, 200, 250, 320, 400, 500, 640, 800, 1000, 1300, 1600, 2000, 2500, 3200, 4000

 

Like I said, I really like my new Lumix LX7. But I would like to get a Camera with a bigger image sensor, like APS-C or "APS-H". I think that will be my next camera. I really like to get the camera for shooting video, because shooting video is a little bit better imho than taking photos. You can show allot more with Video than Photos.

So the Panasonic LX7 has MANUAL exposure control capability and an extremely fast shutter to 1/20,000 sec. The frame rate limit is 60p fps.

Another Panasonic camera, the FZ200, does have high speed video. I believe that the FZ200 has automatic exposure control for high speed video mode.

When I saw your example of 240 fps for the GoPro it really caught my interest because I've been trying for a year or two to pin down the shutter speeds of the many HSV cameras with automatic exposure control, including the GoPros. For analysis, if the cameras have small motion blur they are useful for analysis. But if the motion blur is too large they may not be useful for some applications.

The GoPro has a fast AEC shutter in direct sunlight. Search: GoPro high speed video golf
Look for side views and check the blur on the golf clubs.

The Casio Ex- F1 (2008), FH20, FH25 and FH100(2010) had full manual exposure control. Unfortunately, they are no longer manufactured.
