Panasonic GH5s Slow Motion Samples 240fps!

Panasonic GH5s Slow Motion Samples

There is an aura over the Panasonic GH5s that has not been seen in a m43 camera possibly ever.  It is mainly due to the outstanding low light quality in 4k 24, 30p and 60p that beats full frame cameras like the Canon 5D Mark IV and competes head to head until ISO 25,600 with the king of low light the Sony a7s Mark II.    But as always, our focus is on the high frame rates which the camera also does quite good on.

The 4k 60fps quality is very close to the 30p quality which means excellent and you can shoot at 60p at night without worrying about noise.  The 240fps mode which is a first for a Lumix camera in full HD means that the camera aims to compete with Sony RX series cameras that have stacked sensors. We believe the quality to be acceptable but not good enough to be broadcast quality as stair stepping jaggies are all over the frame with the occasional moire pattern on fine detail that can break a shot. → Continue Reading Full Post ←

Fake Slow Motion Is It Worth It?

Fake Slow Motion

There has been a lot of work put it developing software that can interpolate frames for video editing and compositing applications. Twixtor in the late 90’s was perhaps the first time the technology could make something worthwhile and really produce acceptable results in a computationally acceptable timeframe.

Today the most used algorithm is Adobe’s Optical Flow in Premiere or Time Warp in After Effects which use vector directional plus acceleration of pixel values to derive in between frame data to generate new frame information from the preceding frame as point A and the next frame as point B.  The results can do some wonders to really slow down things above the frame rate ceiling of the camera. → Continue Reading Full Post ←

Canon ME20F-SH Sample Footage Released!

Canon_me20fsh_Sample

Canon Japan has released a sample video showing the Canon ME20F-SH Super High ISO full frame multipurpose camera in action.  It is impressive to see ISOs as high as  on a camera that is as portable as this. Even with a high price of $30k US it is something news gathering and documentary outfits like Nat Geo and Discovery will gravitate to in order to extract new levels of color and light information from extremely challenging low illumination environments.

Filmmakers will also find it useful for shooting in extreme low light for a specific take, but we feel that scientists and biologists in particular will benefit most from these advancements.  Underwater videography is probably the most peculiar use to study bio luminescent organisms in complete darkness like never before. → Continue Reading Full Post ←

Canon ME20F-SH Records 4,000,000 ISO!

Canon_me20fsh_3qlens

The newly announced Canon ME20F-SH Camera besides it’s overly unpronounceable name and a price tag of $30,000 USD has what could be a record for any sensor to date. The ISO 4 million mark on this camera/sensor is able to record footage in full color at night. It over exposes footage only lit by a full moon.  The Sony A7s last year was a revelation of where sensor technology is going with it’s close to 1/2 million ISO at 409,600 . It could shoot in near complete darkness and could do a good job at it.  What Canon has done with the ME20F-SH is build their peak sensor technology into a 35mm Full Frame Sensor but with only 1080p Full HD resolution. The Sony A7s can shoot 4k footage with the HDMI output on an external recorder. This makes the pixel size on the Sony more constrained even with a Full Frame Sensor.

The pixel pitch size on the Sony A7s  (12MP on a full frame CMOS Sensor) is around 8.4 µm; in contrast the new Canon ME20F-SH has a  19 µm pixel size in a Full Frame Sensor.  This is an amazing performer in low light and probably the most sensitive sensor ever made for commercial purposes. At 2.26 Megapixels this is the state of the art for large pixels with impressive dynamic range and low light. It is unclear how the low resolution in such a large sensor will behave when it comes to moire and aliasing artifacts. → Continue Reading Full Post ←

fps1000 Platinum upgrade options unveiled!

fps1000b

The fps1000 Kickstarter camera is ramping up ever closer to final production and shipment and Graham Rowan the creator and genius mind behind these slow motion cameras has released the upgrade option path for Platinum Kickstarter backers.  Pre Order Cameras are also elegible for the upgrade pricing discussed below.  Retail cameras in the future will command a higher price.

As you can see in the table above, the upgrade path is a considerable upgrade from the standard platinum camera “Far left”. We dissect the upgrade Pros and cons for the models below: → Continue Reading Full Post ←

Nikon D7200 Rumor States 120fps Video!

Nikon7100

High frame rates have been stagnant in DSLRs since the Canon EOS 7D with 60fps at pseudo 720p resolution started the higher than 30p spec in mirrored large sensor cameras.

Now – a new rumor posted at Nikorumors.com of the Nikon D7200 DSLR which is replacing the very popular D7100, seems to gain 60fps at 720p to do a total of 120fps at 720p for the first time in a mirrored camera.  Mirrorless cameras like the GH4, a7s, NX1 have already higher frame rate modes but this would be a first for a mirror slap DSLR.  Here are the rumored specs: → Continue Reading Full Post ←
