Phantom Flex4K Manual
The record time is completely dependent on the camera’s
resolution, frame rate, and the size of memory that is
being recorded to. At the camera’s maximum resolution
and frame rate the camera will capture approx. 5 seconds
to 64GB of RAM. If recording directly to a 1TB CineMag at
100 FPS you can record for about 13 minutes. At 24FPS
you can record for about 56 minutes.
A record time calculator is available at
www.
vision
research.com/support or in our Phantom Tools
iPhone app.
At the time of introduction and first shipments the Flex4K
will only save uncompressed Cine Raw data to the
Phantom CineMag IV. The Cine files are similar to previous
Phantom cameras.
Vision Research has announced plans to offer the option
for in-camera compression into the CineMag IV. With this,
you will be able to choose to save files in the Cine Raw
format or with an industry-standard codec.
Vision Research can not release those details while the
feature is in development.
A raw workflow provides the ultimate in image quality
and fastest high-speed workflow in camera. In-camera
compression limits the possible frame rate and save time
to the CineMag. However, saving compressed files has
post-production advantages when it comes to simplifying
the workflow right out of the camera. Files are rendered
and ready for edit. Saving compressed files will also allow
you to record more clips on the CineMag IV as you end up
with smaller file sizes.
No. The Flex4K has a completely new CineMag interface
and is compatible exclusively with the CineMag IV. It slides
in the side enclosure of the camera as opposed to the
earlier CineMags, which mounts on top of other Phantom
cameras with a pogo-pin connection.
The camera has three main 3G HD-SDI outputs
towards the back, one additional HD-SDI output and
one component video output at the front for viewfinders,
and one 3G HD-SDI return. The camera supports:
•
4:2:2 1.5G 1080p/psf/i at 23.9, 24, 25, 29.9 Hz;
720p at 50, 59.9 Hz
•
4:2:2 3G 1080p 50 and 59.9 Hz
•
4:4:4 3G 1080p/psf at 23.9, 24, 25, 29.9 Hz;720p at
50, 59.9 Hz (4:4:4 not available w/ initial firmware)
•
Dual-link 3G 2160p 23.9, 24, 25 and 29.9 signals
The three main outputs are separated as 1x monitor
(MON) output, and 2x recording (REC) outputs. The 2x REC
outputs can be configured as individual 1080p outputs or
used together to provide a dual-link 4K video output. All
outputs are automatically set to the same video system,
the 4K signal is determined by the settings of the other
outputs.
The Component and HD-SDI viewfinder outputs (VF) at the
front always work together, and provide the same image,
with the same overlays, zoom modes, etc. The MON output
can also mirror the VF outputs.
Versatile HD-SDI: The VF, MON and REC B output can be
set to always show a live signal, where the REC A outputs
a clean feed that will switch between live and playback.
This allows the DP & camera operator to always monitor
the live action while the camera is playing back the last
shot or CineMag takes through the REC A outputs.
Video scaling: When capturing at 4K resolution and
outputting at 1080p (for example) the camera will always
scale the video to 1080p.
Monitoring & Log outputs: The Flex4K video outputs can
be switched between Rec709 and Phantom Log curves.
Various zoom ratios can be set from the camera body to
help set focus. Production area rectangles and threshold
mode are also available for the VF and MON outputs to
help judge framing and exposure.
