EOS Movies
Technology always advances and so it is with still cameras. No longer are they limited to shooting still images.Instead they can now also shoot full high definition (HD) movie files.
The EOS 5D Mark II introduced the ability to shoot in full HD movie mode at 1920x1080p resolution.
Using the full sensor provides the advantage of a shallow depth-of-field to help isolate the subject from the background, unlike compact video cameras that use small sensors and have correspondingly wider depth-of-field.
Movies can be captured at 24, 25 and 30fps allowing for both PAL and NTSC usage.
With the Manual exposure settings, all apertures are available and shutter speeds from 1/30sec to 1/4000sec can be selected.
ISO speeds from 100 to 6400 as well as the H1 setting of 12,800 can also be made as per the camera model. Auto ISO can be used too, if you need a particular combination of shutter speed and aperture.
The EOS with the APS-C sensor, mid-range price bracket cameras features the ability to record at 1920x1080, 1280x720 and 640x480 resolutions, but now adds the ability to select from different frame rate settings for more creative control. The options available are 1920x1080 at 24, 25 and 30fps, and 1280x720 and 640x480 at 50 or 60fps. The options available will depend on whether PAL or NTSC is selected for the video system.
Movie Crop
The EOS 550D was the first EOS camera to feature a 'Movie Crop' function that records with the central 640x480 pixel area of the sensor, creating an effective magnification of approximately seven times. The 'Movie Crop' feature gives extra flexibility for capturing subjects that would otherwise be too far away.
The EOS 550D records full 1920x1080p HD video resolution with selectable frame rates of 24fps, 25fps and 30fps, as well as 720p video at 60fps and 50fps. The EOS 600D takes the movie crop function a stage further than the EOS 550D by using Movie Digital Zoom to magnify the centre of the sensor by between 3-10x while still retaining full HD movie quality.
Video Snapshot
The EOS 600D added a new feature to movie shooting – Video Snapshot. This makes it possible to capture short clips of two, four or eight seconds in length, which are then stitched together into one single file called a 'Video Snapshot Album'. This helps new users make dynamic and fast-paced sequences of clips. After selecting the length of the Video Snapshot clip, each time a movie is recorded it will be that length.
Audio Recording
Audio recording is very important for movie shooting – good quality audio really helps improve the footage. To aid this, various Canon DSLR's have manual audio level setting within the camera menu system.
Maximum recording times
With the release of the EOS-1D X and EOS 5D Mark III, the maximum recording time for a single clip has been increased from approximately 12 minutes (depending on content) to 29mins 59secs. This has been made possible because when a file reaches the file limit of 4GB, the camera simply creates a new file and continues recording. While the full run of 29mins 59secs will be saved in several separate files, playing them back on the camera, or joining them together in editing software will create a complete run with no breaks.
Compression
When recording HD Movies, the format in which the file is saved can have an effect on how easy it is to playback or edit. All of the EOS DSLR cameras capable of shooting HD Movies (before the launch of the EOS-1D X and EOS 5D Mark III DSLRs), use a compressed stream of data where there is a key frame and subsequent frames are compressed relative to that. It is technically known as IPP compression.
The EOS-1D X and EOS 5D Mark III cameras improve on the compression options by offering two compression choices: IPB or ALL-I.
With the growth in popularity of the EOS Movie functions found in all current EOS DSLR cameras, some users requested the ability to record or view what the camera was recording on an external device through the HDMI port.
