Looking at the current crop of portable devices that offer slow motion is hard and it’s pretty much a mine field. Lenses differ, sensor sizes are varied and distortion can creep up.
The Memory card brand Transcend has entered the SDXC I U3 market for 2k and 4k video cameras with two low cost offerings:
- 128 GB High Speed 10 UHS-3 Flash Memory Card 95/60 MB/s TS128GSDU3
- 64 GB High Speed 10 UHS-3 Flash Memory Card 95/60 MB/s TS64GSDU3
Both offer a minimum sustained write speed of 30 Megabytes / second which is the minimum spec for U3 and 2k, 4k video recording. These cards should alleviate the pockets of new 4k consumer camera owners at $54.99 for 64GB and $119.99 for 128GB.
The newest line of Panasonic camcorders announced at CES are a step forward in the codec department with up to 50mbps at 60p but the feature that caught our attention is that both the HC-W850 and HC-V750 can record 120 frames at 1080p plus interpolate to 240p by using pixel motion algorithms.
We have been closely following the GH4 since leaks started appearing a few months back. Initial rumors said that 1080p 120 frames/sec will be included as-well as a 240 frame 720p mode. The hype machine was running full seam back then.
When the camera specs were announced and the dust settled we were left with a 96 frame Full HD 1080p camera that claims to be full quality in a variable frame rate mode “No Audio Recorded in This Mode”. What of the 240 720 mode? It seems the camera has done without even the 720p specs of older GH cameras.
The just released Sony FDR-AX100 Handycam is not just a 4k recording multipurpose camera but it also hides a 720p 120f mode which so far seems to be lower quality than regular 720p video cameras. The quality while usable is not ideal. The resolution seems to be well below the stated 720p in slow motion mode.
There is a sister model with the same sensor called the HDR-CX900 which shares all features “Including 720p 120F recording” except the 4k recording and of course a discounted price. However the $500 shave might be unwarranted considering the 1.5k investment for the CX900 which for $500 more you get 4k on the AX100.
