The EOS 5D Mark IV features a time-lapse movie shooting option to create time-lapse directly in-camera without needing to stitch the images together afterward. When you shoot a time-lapse movie, you will notice that the resolution is FHD and it is recorded at either 29.97P (NTSC) or 25.00P (PAL). If you wish to record a timelapse at a higher resolution or with a different frame rate, then you should use the interval timer instead to capture still images that you can later combine on a computer. This will allow you to capture a timelapse at a much higher resolution, in RAW, or with a faster or slower frame rate as required.
This feature works well with trade show set-ups, construction projects, and beach sunrise and sunsets. The camera should be mounted on a tripod and placed where it will not be moved for best results.
