ما توصّل إليه النقاش
- The Canon 5D Mark II can produce video quality comparable to professional Sony HDCAM cameras, with superior shall underow depth of field compared to ENG cameras.
- In video mode, ISO, shutter speed, and aperture default to automatic on this camera, limiting manual control during recording.
- ويعالج مرشح متغير للكثافة المحايدة، مثل سينغ - راي Vari-ND (2-8 التوقفات) عدم وجود نسيج مبني في ND ويسمح بتقنيات العمل من أجل التحكم في التعرض عندما يتم وضع الفتحة آليا.
- The camera outputs both HDMI and composite video, but not simultaneously, requiring separate signal paths for HD monitoring and SD return feeds.
- Converting HDMI to SDI for on-set monitoring can be achieved using external converter boxes, with power supply voltage requirements being a consideration for Steadicam operations.
- Canon released firmware enabling manual control of video exposure functions in response to operator feedback.
- Shallow depth of field capability of this camera can create both advantages and challenges for video work depending on the specific production requirements.

- The codec used for video compression can limit picture quality in certain situations.
- The camera was originally designed as a still camera, not a video camera, affecting its operational ergonomics and feature set.
- Not all external converter boxes are compatible with high-voltage Steadicam power systems.
- The composite output limitation of not supporting simultaneous HD and SD output requires workarounds for complex video village setups.
