Manual video mode Recording videos
Manual video mode lets you control all your camera’s settings. This is particularly useful for controlling the depth of field when shooting video.

These settings operate in the same way as in Manual photo mode (described in section “Advanced modes” ).
The aperture control feature lets you manage your depth of field: a wide aperture (ƒ/1.8, ƒ/2.8, etc.) gives a shallow depth of field and a markedly soft background, while a narrow aperture (ƒ/5.6, ƒ/8, etc.) gives greater depth of field.
The shutter speed control lets you manage the fluidity of your video. Because the Manual video mode films at 30 frames per second, we recommend you use a shutter speed of 1/30 s as much as possible to ensure maximum fluidity. A much higher shutter speed (e.g. 1/500 s) will give a cleaner video, but will also be jerkier.
The sensitivity can be left in automatic mode (in which case the exposure is automatic), or selected manually.
If you want to open the iris when there is a great deal of ambient light, you may have to use a high shutter speed, which could create fluidity issues.
In this situation, you can use the Optical Adapter and a neutral density (ND) filter. This will reduce the amount of light entering the iris and let you photograph at slower shutter speeds with a wide aperture.
