One Plus 5 Debuts With Only 720p 120fps!

One Plus 5

There were a lot of expectations for the phone that would replace the One Plus 3T which was a mighty seller for the performance hungry crowd without the high price tag that typically goes along with the best phones.  The new One Plus 5 is a good upgrade from the One Plus 3 and 3T in that the performance goes neck and neck with the best of the best out there and tied with the Samsung Galaxy S8 in benchmarks.

The tale, however, is not completely rosy as the camera module taking a page from the iPhone 7 Plus includes two camera sensor modules, one for wide-angle at 16MP and the other for telephoto with 20MP resolution.   We say it falls short because the slow motion frame rates are pegged to a 720p resolution and only at 120fps. This is not flagship performance for video even when it ticks off all the other boxes like 4k 30p and 1080 60p.

Schlieren Imaging Slow Motion DIY!

Schlieren Imaging Slow Motion

Sometimes all it takes to embark on a new project is some unexpected inspiration.  On the Incredible Slow Motion video by Veritasium – Seeing the Invisible: Schlieren Imaging in SLOW MOTION we are not only inspired but awestruck by the results of this simple and doable at home scientific experiment.   The experiment allows a camera to visualize the vortexes of gases and temperature differences in the air which serve to create some very interesting scientific experiments and or artistic visualizations.

You will need a Concave Parabolic Mirror like the ones used in reflective Newtonian telescopes, “you may have one lying around from your stargazing days”,  you will also need a small light source like an LED flashlight or single diode and finally a razor blade or similar precise object to cut off the light to the camera on a plane.

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.

Canon C200 Cinema Camera 120fps Slowmo!

Canon C200

There is no question Canon has had great success with their EOS Cinema line of cameras. They continue to dominate the rental production market and even when they are overpriced compared to competitor’s options it is in a class of its own when it comes to Dual Pixel Continuous AF with Canon EF lenses which are plentiful and part of the stable of most serious camera professionals.

The latest iteration just announced is the Canon EOS C200 EF Cinema Camera which has some serious performance improvements over the current price/performance kind in their camera line. The new camera slots between the lower priced C100 Mark II and the more professional 4k C300 Mark II. However the C200 records in 4k RAW Light format which gives 15 stops of dynamic range with all the benefits of RAW editing with some compression.

DJI Spark Mini Drone Lacks High Frame Rates!

DJI Spark

The newly announced DJI Spark Selfie Micro-drone is a thing of beauty when it comes to capability vs size.  At just $499 it is also half the price of a DJI Mavic Pro and while it lacks a 3 axis gimbal and extended flight time; this is geared to the people that want a no nonsense experience that is truly portable for their flight camera needs. It has a camera capable of 1080p video of pretty good quality at 30fps.

The downside is that it lacks 4k for one thing and any other frame rates besides 30fps full HD.  It does do  12MP still images with good dynamic range and color accuracy which could become the best use of the drone for markets such as real estate, surveying and aerial imaging that is ready at any moment without the bulk.

Olympus Tough TG-5 Digital Camera 120fps 1080p!

Olympus Tough TG-5

Olympus is announcing the TG-5 rugged camera which is the replacement for the popular TG-4. It has quite a number of new features and what may be a first for this type of cameras; a sensor pixel density reduction from 16MP to 12MP. A welcomed addition that will ensure better low light quality with a BSI CMOS sensor and speedier data acquisition which lets it output 4k and 120fps 1080p video.

It has also a 720p 240fps mode and a VGA 480fps mode which makes it stand out in the slow motion categories. This camera seems to be aiming at the GoPro Hero 5, Yi 4k+ and Sony Action Camera markets with more features, better usability and the features you expect from a portable camera. It can also be used in drones with some creative placement due to its low weight of 250g with battery!
