I’ve been finding out as much as I can about the video mode on the Canon Eos1DmkIV. Here’s the latest info I’ve received from Canon Europe.
It has essentially the same video frame rates and data rates as thebut with a 1.3x crop factor. These rates include 1080/24p/25p/30p as well as 720p/50/60p. The ISO in video mode is ISO 100 to ISO H3 when shooting in manual mode (with custom function C.Fn I-3 setting enabled). Auto ISO is also available.
The audio remains the same as thewith no additional manual controls – such a shame. The 1DmkIV shares the same higher audio frequency range and sample rates as the , besting the .
The 1DmkIV also shares the 4gb file size limit of the 7D and. This is due to the size limit of FAT32 file system.
Also missed is the opportunity to shoot to both card slots at the same time, sadly the 1DmkIV can only record to one card at a time. Also absent is any cropped sensor mode in video, surely this will come – but not yet it seems.
There is a new wi-fi pack for the camera but no new audio accessories like an XLR box as some had speculated. Looks like we’ll be using Beachteks, Juicedlinks and audio recorders like thefor some time to come.
In order to start video recording you need to press the FEL button or you can activate it tethered using a computer and EOS utility. It seems there is no option for IR start/stop like theand 7D, but I need to confirm this.
More as I get it.
