The invention discloses an intelligent film shooting lamp box, and provides an innovative design for solving the problems that a traditional lamp box is inflexible in rotation, poor in heat dissipation, insufficient in stability and the like in film shooting. The light source box is matched with the opening portion through the annular protrusion of the bearing table to achieve rotation, the bearing table is driven by the rotating mechanism, the rotating handle is driven by the bevel gear and the first bevel gear to rotate, and the multi-angle light supplementing requirement is met. The heat dissipation mechanism is composed of a rotating rod and blades, is linked with the rotating shaft through a transmission belt, and generates airflow for heat dissipation and dust removal during rotation. In the stabilizing mechanism, a second bevel gear is matched with a bevel gear, so that a moving rod drives a stabilizing rod and a clamping mechanism to act, the gravity center is adjusted, tripod supporting legs are clamped, and toppling is prevented. All the mechanisms of the lamp box work cooperatively, shooting efficiency, picture quality and equipment stability and safety are effectively improved, and the lamp box is suitable for the field of film shooting and the like.

The present invention generally relates to optical imaging systems able to form an infinity corrected beam from light received from a front lens system, thereby standardizing the working distance of any front lens system able to be integrated with the present invention. This allows a wide variety of front objectives to be used interchangeably with photographic and motion-picture cameras and other optical instruments, and also allows front objective lens systems to be miniaturized or otherwise modified.

A cinematography battery pack includes a first surface, a second surface, and at least one latch. The first surface includes at least one latch receiver. The second surface includes at least one first magnetic member. The at least one latch is movable between a first position where the at least one latch is recessed below the second surface, and a second position where at least a portion of the at least one latch protrudes from the second surface. The at least one first magnetic member is configured to magnetically engage a magnetic member of at least one of another cinematography battery pack or a cinematography accessory, and the at least one latch is configured to mechanically engage a latch receiver of the at least one of the other cinematography battery pack or the cinematography accessory when the at least one latch is in the second position.

An ultra-large aperture single-lens reflex full-frame lens belongs to the technical field of cinematographic equipment. Along the light incident direction, the lens is successively provided with a first lens group with a negative diopter, a diaphragm, and a second lens group with a positive diopter; the diaphragm is located at any position in the second lens group; when the object is focused from infinity to a short distance, the first lens group remains stationary, and the second lens group, as the focusing group, axially moves from the image plane side to the object side direction; and the lens satisfies the conditional expressions: 2.5 ≤ |F1 / F| ≤ 7; 0.05 ≤ |D12 / F| ≤ 0.2. Compared with the existing large aperture lenses, the ultra-large aperture lens of the present invention has a larger aperture, and the aperture size can reach F0.90 to F1.15. Excellent imaging effects can be achieved from infinity to a short distance, and miniaturization, low cost, and easy mass production are realized, having good practical value.

A motor mount for a cinematography lens of a camera is provided. A main body has a first end and an opposite second end, the first end configured to fixedly couple to a camera rod of the camera and the second end is configured to support a moveable arm. The arm is configured to support a motor for selective engagement with the cinematography lens. An actuator is supported on the main body proximate the second end. The actuator is coupled to the arm such that the motor is moveable via the actuator between at least a first position whereby the motor is disengaged with the cinematography lens and a second position whereby the motor is engaged with the cinematography lens and without movement of the main body on the camera rod.

A cinematographic equipment system and a cinematographic device, wherein the equipment system has at least one cinematographic device selected from the group consisting of a motion picture camera, a lens turret drive component, a mother lighting device and / or a remote control component, and at least two different radio modules. The cinematographic device has an interface for selective coupling to one of the two different radio modules, each of the two different radio modules being used for wireless transmission of control signals, further for wired communication with the coupled cinematographic device via the interface, and the two different radio modules differ from each other in their radio characteristics, i.e. in the used frequency range and / or in the used transmission protocol.

The present invention relates to an instrument (1) for objectively measuring the dispersion of light, which is useful in the cinematography and audiovisual sector. The invention overcomes the lack of precise tools, eliminating the relativity of the concept. The instrument of the invention consists of a semi-sphere (2) made of a matte material and having a known size, serving as a constant subject. When the instrument is oriented toward a light source, an external device captures an image of the dispersion of light over the semi-sphere (2), providing an objective measurement of the dispersion. The instrument can include marks (3) for orientation, a mirrored semi-ellipsoid (5) for complementary analysis of the source, and sight holes (6, 7) for alignment. The primary use of the instrument is for evaluating and standardising the measurement of the dispersion of light on a known and constant object that takes the place of a subject.

A method and device for one-click filmmaking are provided. The method includes: obtaining a script from a user, detecting a single user operation, in response to the single user operation, obtaining a plurality of shots and estimating information of the plurality of shots based on the script, and automatically generating a film based on an auto-cinematography algorithm and the estimated information of the plurality of shots. The estimated information of one of the plurality of shots comprises at least one of a character of a shot, a scene of the shot, one or more positions of the character in the shot, a duration of the shot, or a shot type.

The application relates to a digital role action synthesized video training data generation method and system. The digital role action synthesized video training data generation method comprises the following steps: writing a rendering task of an action synthesized video into a shared task queue, wherein a combination of film semantic parameters of the rendering task is obtained by values of shooting dimensions conforming to a cinematography specification; making multiple rendering nodes concurrently take rendering tasks from the shared task queue by executing an atomic declaration mechanism; each rendering node executes a rendering work according to a configuration parameter to generate a corresponding frame image sequence; converting the frame image sequence into a video file, packing the video file and a structured annotation record to obtain a training data entry, and obtaining a training data set composed of multiple training data entries. The application solves the problem of poor production efficiency of a synthesized video training data generation system.
