Sony a7s III Slow Motion Samples!

Sony a7s III Slow Motion Samples

Now that the excellent a7s Mark III video recording mirrorless camera has been out for over six months, it is time to revisit the slow motion component and see what quality we can expect from the Sony a7s III Slow Motion Samples. Many have praised the 4k 120fps mode which is heavily detailed, low noise and suffers from only a very small crop factor that is hardly a problem.

We looked at the Full HD 1080p 240fps mode on the camera and it was clear it did not match the 120fps 4k mode as it was not only less detailed but full of aliasing and moire if you looked for it. It was clear the camera was not up to professional standards when in this mode which is to be expected from a full-frame sensor cropping to 1080p. That said, this camera is a powerhouse that easily takes the mantle as Sony’s best mirrorless compact video camera. → Continue Reading Full Post ←

Fujifilm X-E4 Slow Motion 240fps disappoints!

Fujifilm X-E4 Slow Motion

The recently released camera called the Fujifilm X-E4 shares many of the traits of their lower brethren but also from the higher-end models in a compact package. It ditches the better viewfinder for a small 2.36 million dot EVF that makes it a bit hard to see your composition but that also allows the camera to be smaller and more stylish than the beefy SLR style Fujis out there.

The Fujifilm X-E4 Slow Motion feature is the same as found on cameras like the excellent Fujifilm XS-10 which is a 120fps or 240fps full HD component that records in camera. Why are we not excited? well, the quality is lower than expected with some aliasing and moire characteristics that are so last decade. When are manufacturers going to offer the same 1080p quality at all frame rates instead of relegating the 120fps and 240fps modes to the lower bitrate and detail bin? → Continue Reading Full Post ←

Fuji X-S10 Slow Motion 240fps Samples!

Now that the surprise camera of 2020 has been out for a while, it is time to revisit the 240fps mode included in the video features. At first glance, it delivered 720p quality or less in an upscaled 1080p wrapper.  However many Fuji fans asked us to revisit the slow motion quality of this camera as early samples supposedly did not do justice to what this mode was able to deliver.

We have to agree to some extent that the quality of this camera in 240fps Full HD slow motion is better than other even more expensive options but we still feel that Fuji cut corners when it comes to image quality here by dropping lines and having a pretty noisy output unless there is an ample amount of light.  We have some samples that will let you see what this camera is capable of and make you decide if it is a good enough option for your camera collection. → Continue Reading Full Post ←

Slow Motion on DJI Pocket 2 & Fuji X-S10 Offers 240fps!

Slow Motion on DJI Pocket 2 & Fuji X-S10

Two very different new cameras were released this week that are able to shoot in 240fps Full HD 1080p. One is the Fujifilm X-S10 which is an all-rounder mirrorless camera with 6 stop IBIS and cinema video profiles for $999 body only, the other is the sequel to the very well received DJI Osmo Pocket now named DJI Pocket 2 dropping the OSMO part of the name & starting at $349 in its most basic form. Slow Motion on DJI Pocket 2 & Fuji X-S10 is close on both.

Both cameras are able to do 120fps as well but the interest peaks at 240p where the speed makes things moving slower more detailed, especially people as at that speed lifeforms moving relatively slow are excellent subjects. For faster animals like birds or flying insects, you need many more frames per second, usually in the 700+ range to create a good enough effect. → Continue Reading Full Post ←

iPhone XS Slow Motion Samples!

iPhone XS Slow Motion Samples

After a few weeks of iPhone XS ownership, we can already gage the quality of the video coming out of the device in 1080p slow motion mode. We have a dozen samples for you too look at and make a decision. It is, however, a bittersweet realization that last year’s iPhone X is pretty much just as good as the XS in slow motion with just a tiny difference in per-pixel quality and dynamic range.

If you own an iPhone 8, X or Samsung Galaxy S8 or S9, for example, the slow motion feature on the iPhone XS should not be a factor in your decision to upgrade. The new XS has the best 4k video the iPhone has ever produced and the image stabilization is also much improved. The XS camera shoots pretty amazing still images and regular frame rate video but it is competitive with the best out there. The phone still is the best 240p 1080 mobile device today, see why below. → Continue Reading Full Post ←

iPhone Xs Slow Motion Official Apple Sample!

Apple has released a preview video showing the video capabilities of the iPhone Xs in 4k 30, 4k 60 and slow motion 1080p 240fps.  You can see in the liquid and sound part of the demo the quality delivered by the full HD slow motion but it is hard to judge per pixel sharpness and or artifacts from such a short high shutter video. We will need more real-world samples in order to see if there has been an improvement from the iPhone X of 2017.

We have isolated a part of the footage to see the slow-motion compression and we could detect aliasing in the edges, softness and compression artifacts which are typical of mobile phone high frame rates. The iPhone Xs seems to still have them to some degree. Color and motion on the codec seem to be excellent especially in 4k which looks extremely detailed and with more than acceptable dynamic range. → Continue Reading Full Post ←
