Incidentally, there is also a frame rate and exposure calculator and a lens calculator to helps you select the correct lens for a Phantom camera based on some details about your shot. With the Flex4K selected, choose the appropriate CineMag and memory size in order to simulate recording directly to that CineMag. At the camera’s maximum resolution and frame rate the camera will capture 10 seconds of video to 128GB of RAM.Ī record time calculator can be found in the ‘Support / Resources & Tools’ section of the Phantom website, as well as in the ‘Phantom Tools’ iOS App, which lets you estimate the maximum frame rate and record time at any given resolution. The record time is completely dependent on the camera’s resolution, frame rate, and the size of memory that is being recorded to. It’s worth noting that the camera maker has no plans to add other ProRes formats, feeling that, if higher quality is required, then Cine RAW is a better option. Over five hours of 24fps ProRes HQ footage can be stored on a 2TB CineMag IV. The files in the mag are about 2.5X smaller than the un-interpolated RAW files, and take that much shorter to save from the camera or CineStation IV. CineMag IV-PRO mags are much faster, and actually the save time is equal to saving RAW. Saving in ProRes HQ mode takes about three times longer to the CineMag IV than saving RAW. In Loop mode, the camera will allow up to 938fps to RAM, before the file is saved to the CineMag. 2K ProRes recording at higher frame rates is also available on the CineMag IV-PRO (in fact you can record in up to 1,775 fps in 2K). In Run/Stop (RS) mode the camera will allow up to 30 fps direct to a CineMag IV, and 120 fps with a CineMag IV-PRO. The CineMag IV will not support any other resolutions to record when set to ProRes. ProRes files can be saved to the CineMag as 4K or scaled 2K resolution. When working with ProRes, Vision Research advises the camera be set to full sensor resolution (4096 x 2304). Using ProRes recording, of course, saves storage and increases total record time. For example, a 10 second clip at 1000fps would take about 40 seconds to download although more often than not you’d have trimmed the clip in-camera which would reduce download time further. Superfast download to CineMags can be accomplished in seconds. The full- size images are delivered via 9.4 Gpx throughput in the Cine Raw file format. With the Flex4K you have the option of recording in Cine Raw or ProRes 422 HQ and to maintain that option you’ll need to rent either a CineMag IV or CineMag IV-PRO). Or you can set the trigger anywhere in the middle, for example, having 90% of the recorded movie be what happens prior to the trigger and 10% after the trigger. If you set the trigger to stop the recording (0% post trigger) and save all frames up to the time of the trigger, the camera will simply stop recording upon the trigger and all the frames in memory before the trigger will be saved. In this mode, once the trigger is pressed any images already in memory are overwritten and you record until memory is full, then it stops. It can be set so that only frames that occur after the trigger are saved (100% post trigger). This is called ‘circular buffer recording.’ What you end up actually saving in memory is a function of how you’ve set up your trigger. When it gets to the end of memory, it cycles back to the beginning and continues recording, constantly overwriting itself – until the camera is triggered. When the camera is in the pre-trigger mode (you’ve pressed ‘Capture’ in the user interface), the camera is continuously recording images into that memory. The Flex4K comes with a fixed amount of high-speed dynamic RAM. Secondly, when each shot can average between 64GB and 128GB, you need to be prepared to be able to work with that much footage or your daily rental costs are going to mount.īefore you dive in, consider the following tips to efficient and expert shooting with the Phantom Flex4K. Firstly, it’s expensive-the camera can cost upwards of $100,000, making it a rental option. Originally devised for medical and scientific work by camera maker Vision Research, the Flex4K captures professional cine quality video and is a regular part of high-end commercial shoots. Sporting a super-35mm CMOS with a full resolution of 4096 x 2304, this specialist unit produces highly detailed low noise 4K images at 938 fps. The Phantom Flex4K is the ultimate in slow-motion capture. If you want super-sharp ultra-fast motion imaging for your next project then there really is only one camera to turn to. 5 Things To Consider When Shooting With The Phantom Flex4K Camera
