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 ←

Huawei Mate 30 Pro New Slow Motion Samples!

Huawei Mate 30 Pro New Slow Motion Samples

The Huawei Mate 30 Pro has been out for a few weeks outside the US, mainly in China and India and we have gathered 15 video samples from its slow motion mode which as of today is the best performing high-speed phone ever developed.  We had some shortcomings about the way the phone reaches the highly hyped 7,680fps mode which is 1920fps multiplied by 4x in software from a small snapshot of the video memory.

We also had some suspicions that the 1080p 960fps mode was also interpolated but looking at the samples we gathered it seems that was a premature call. The phone is actually capturing the full frame rate at 1080p or close to that.  The real max mode is 1920fps at 720p which is then interpolated to 7,680fps with good success by the new Kirin 990 chipset. Your mileage may vary and the results depend on the subject matter more than anything as organic slower motion looks much better than fast unpredictable bursts that break the interpolation algorithm. → Continue Reading Full Post ←

Huawei Mate 30 Pro Slow Motion The Real Story!

Huawei Mate 30 Pro Slow Motion

Huawei has just launched the Mate 30 Pro and Mate 30 Pro 5G Smartphones which sport an impressive camera module with a large sensor array that shoots at 40 Megapixels.  We had rumors sent a couple of weeks back but had our reservations due to the less than optimal slow motion in the P20 and other Huawei Smartphones.  The phone is now untouched by the competition as it can shoot a half-second at 1920fps 720p or 960fps total which translates to 32 seconds on a 30p timeline.

The headline slow motion feature of 7680fps is not real as it is derived from the 1920fps 720p half-second which the phone then uses AI selection to isolate a 0.12 seconds segment of the capture then finally interpolated by the Kirin 990 Chipset to the full 7680fps. So it does a 4x slow motion on top of it to get the great-looking result. → Continue Reading Full Post ←

Sony a6300 Rolling Shutter for Slow Motion?

Sonya6300rs

There has been a lot of talk lately about the Sony a6300 horrific rolling shutter performance.  Most early adopters are crying foul at the skew and jello movement artifacts when hand holding, panning or using a long telephoto lens.  There is however a big question that has been answered concerning 1080p;  that is how bad is rolling shutter in the 1080p modes including 120fps? Sort answer is about 1/10th to 1/6th that of the 4k mode.

Mark Puckett of the Photo /Video Show set out to find out about the rolling shutter in the Sony a6300 first hand using panning motion while testing the different modes in the camera including 4k 24p, 30p nad 1080p 120fps and 60fps. → Continue Reading Full Post ←

Sony a6300 delivers 4k Plus 120fps FHD Slowmo!

Sonya6300

The Sony a6000 was a good middle of the line performer with pretty competitive performance. The new a6300 is a refined version with some pretty robust improvements in the video area.

For starters the 4k 30p, 24p, 25p video internal mode records in the robust XAVC-S video format at up to 100Mbps which is comparable to what the Panasonic GH4 and a7s II cameras record 4k into.  It also has S-Log3 Gamma for a flat profile for creative grading and LUT application for editors and colorists.   If you were looking for a Sony 4k alternative in an S35 crop sensor then this is the camera for you.   Furthermore the 4k mode is using the entire S35 frame and correctly down-sampling the image for extremely crisp looking 4k video from a 6k original sensor source. → Continue Reading Full Post ←
