<P> While the Nikon D90 was the first DSLR to shoot 720p high - definition video, and the Panasonic GH1, a MILC, was capable of 1080p / 24 recording before the 5D Mark II officially gained this capability, the latter was the first full - frame DSLR to feature 1080p video recording . The Canon PowerShot SX 1 IS followed with 1080p video in a bridge digital camera soon after . </P> <P> The 16: 9 aspect ratio portion of the sensor used in video mode is similar in sensitive area to a VistaVision 8 / 35 frame . This large sensor allows videos to be recorded with very shallow depth of field for a "film look". The 21 megapixel sensor is downsampled to HD resolution by only using every third line and 4: 2: 0 chroma subsampling, leading to concern about Moiré patterns in recorded video . </P> <P> Video clips can be up to 4 GB in size, approximately 12 minutes of 1080p HD or 24 minutes of SD (640 x 480) footage . These limits stem from the 4 GB maximum file size supported by the FAT32 filesystem format used on Compact Flash cards . The camera also imposes a hard maximum clip length of 29 minutes 59 seconds if the 4 GB limit has not already been reached . Video and audio is recorded to QuickTime (MOV) container files with H. 264 / MPEG - 4 (Base Profile @ L5) compressed video and uncompressed 48 kHz / 16 - bit PCM audio at . The bitrate for 1080p is approximately 38 megabits per second (4.8 Mbyte / s), while for SD it is approximately 17 megabits per second (2.2 Mbyte / s). Although the internal microphone is mono, stereo audio is supported through the audio input jack . When recording for long periods, especially in warmer climates, increased video noise may occur due to CMOS overheating . </P> <P> The EOS 5D Mark II is capable of video recording in low - light situations and it is sold for a relatively low price, compared with professional video cameras . For the first eighteen months of its release, the camera only had a 30 frame per second (30p) video mode . On 15 March 2010, Canon released a firmware upgrade to add a 25p mode for PAL format compatibility and a 24p mode for compatibility with motion picture film cameras . </P>
