My current 5D, the Mark IV has proved to be a reliable workhorse and I upgraded from the Mark III because I transitioned to shooting a lot of video content. The Mark IV brought a host of new video features, with the most important of them being the option of ultra high-quality 4K footage (albeit with a considerable crop, although that sometimes Although most EF-S lenses would cover the 1.7-cropped area of the 5D Mark IV's sensor. that's active in video mode, they still can't be used. Even so, this doesn't seem like a very big deal. The term 'crop factor' is dubious enough in itself, but a sensor having an effective crop of 1.7 is only slightly smaller than most APS C cameras which Along with capturing beautiful 4K videos, the EOS 5D Mark IV with Canon Log is equally able to shoot Full HD video at up to 60p plus HD at frame rates as high as 120p, ideal for smooth slow-motion video. It also supports both MOV and MP4 formats for a variety of applications right out of the camera. * 4K requires the following write speed It could be that the frame buffer for 4K and DIGIC 6 is quite different to the usual way video works on Canon bodies like the 5D Mark IV. Developer A1ex wrote on the Magic Lantern forums here: – jumping to Canon’s main firmware finally works (this fixed it) – loading ML alongside main firmware works, too (startup code nearly identical to Both cameras feature 4K video recording up to 30fps with high bitrates. The EOS R does Ultra HD (3840×2160) and allows you to choose between IPB and All- Intra compression, with the latter going up to 480Mbps. The 5D mark IV uses Motion JPGs and records in the Cinema 4K format (4096×2160) at 500Mbps. Camera: Canon 5D IV. Hello, I have recently started recording in 4K (4096x2160 - 29.97 fps - MOV) I noticed that I can't import it to my PC when the videos get longer, 20 sec videos work fine. But anything above that it just won't show up when I try to import it to Windows. They run fine on my camera, I can replay them etc. Solution. *1 : Type I, UDMA Mode 7 supported. *2 : UHS-I cards supported. Cards that Can Record Movies: When shooting movies, use a large-capacity card with a reading/writing speed (required card performance) shown in the table or higher than the standard specification. Test the card by taking a few movies in the desired quality and make sure They seem too punchy and skin tones quickly become unnatural. That's why I've created a set of Canon log to Rec709 LUTs designed specifically for Canon log on the 5D Mark IV and EOS R. 5D Mark IV lens choice. The other issue with the 5D Mark IV's 4K video mode, is the fact that it has a 1.64 crop factor. DCBkTE.
