To capture your video signal, you’ll need a video capture card. Video capture cards come in a range of prices with a multitude of features. Most consumer capture cards today are targeted towards folks who want to watch TV on their computers and may want to record television programs. These cards tend to be Lower quality and focused more on the TV tuner than the video quality.
Synthesis and phase transition behavior of calamitic liquid crystals containing heterocyclic core and lateral ethoxy substituent

Phase-transition temperatures and associated enthalpy changes were measured using a Differential Scanning Calorimeter Mettler Toledo DSC823e at heating and cooling rates of 10°C/min and −10°C/min, respectively. A polarizing optical microscope (Carl Zeiss) equipped with a Linkam hotstage was used for temperature-dependent studies of the liquid crystal textures. A video camera (Video Master coomo20P) installed on the microscope was attached to a video capture card (Video Master coomo600), allowing real-time video capture and image saving. Optical textures exhibited by the compounds were observed using polarized light with crossed polarizers. Samples were prepared as thin films sandwiched between a glass slide and a coverslip. Phase identification was made by comparing the observed textures with those reported in the literature [35,36].

Muscle architecture. BFLH Lf, pennation angle (θp), and MT of the dominant leg were examined using B-mode ultrasonography (EUB-8500, Hitachi Medical Systems UK Ltd, Northamptonshire, UK) with a 9.2 cm, 5–10 MHz linear-array transducer (EUP-L53L). Ultrasound measures were performed with participants lying prone on the same rigid custom-made isometric dynamometer that was used to perform unilateral maximum isometric strength measures (knee and hip angles of 150° and 140° [180° = full extension], respectively). The transducer (coated with water-soluble transmission gel) was positioned along the median longitudinal line (50% of superficial medio-lateral width) of the BFLH at 50% of the distance between the ischial tuberosity and the popliteal fossa with minimal pressure applied on the dermal surface. The transducer was orientated perpendicular to the skin and parallel to the BFLH fascicular path. Appropriate transducer orientation was defined as the orientation resulting in an image with the aponeuroses and the perimysium trajectory of several fascicles being clearly identifiable with no visible fascicle distortion at the edge of the image. Five seconds of video output from the ultrasound machine was exported to a personal computer (via an S-video to USB converter) and images were recorded using ezcap video capture software. Images were later imported into a public domain software (Tracker, version 4.87, www.cabrillo.edu/dbrown/tracker) for analysis.
Synthesis and mesomorphic behaviors of a series of heterocyclic pyridine-imine-ester based liquid crystals

Phase-transition temperatures and associated enthalpy changes were obtained using a Differential Scanning Calorimeter Mettler Toledo DSC823e at heating and cooling rates of 10 and −10°C/min, respectively. A polarizing optical microscope (Carl Zeiss) attached to a Linkam hotstage was used for temperature-dependent studies of the LC textures. A video camera (Video Master coomo20P) installed on the microscope was connected to a video capture card (Video Master coomo600), permitting real-time video capture and image saving. LC textures exhibited by the samples were observed using polarized light with crossed polarizers. Samples were sandwiched between a glass slide and a cover slip to form a thin film. Phase identification was made by comparing the observed textures with those reported in the literature [55,56].
