As mentioned above, EOS M50 can record 4K video at either 24 fps (actual 23.98 fps, when camera is set to NTSC-type video recording), or 25.00 fps for PAL-compatible regions. Faster frames per second recording speeds will require switching to Full HD or HD recording.

In [: Movie rec. size], you can set the image size, frame rate, and compression method. The movie will be recorded as an MP4 file.
Since the movie is recorded at a bit rate lower than with IPB (Standard), the file size will be smaller than with IPB (Standard) and the playback compatibility will be higher. This will make the possible recording time longer than with IPB (Standard) (with a card having the same capacity).
Hi, I'm planning to use the Canon 1DX mark ii for shooting video, can someone please tell me how many mins of footage of 1080p@24fps and 1080p@60fps, ALL-I and IPB video would fit into a 128GB Cfast 2.0 card?
High-definition video capture has rapidly become a must-have feature in this year's digital SLRs, with advanced amateurs and budget-minded professionals alike excited by the possibility of using the same camera body and lenses for both still and movie shooting. Most digital SLR video modes to date have had limitations in terms of control and output formats that have tempered this excitement somewhat, however.
Individual movie clips captured by the Canon EOS 7D are limited to a maximum of twelve minutes in the high definition 1080p and 720p modes, or 24 minutes in the standard definition VGA mode. (Canon didn't give a reason for this, but perhaps it's a matter of power consumption and sensor heating: We noticed that the body can get rather warm after an extended period of video shooting.) The Canon 7D records its movies as MOV files using AVC / H.264 compression, which is much more conservative of memory card space than the Motion JPEG format used by some cameras, and avoids some of the severe image quality loss suffered by AVCHD cameras when faced with significant amounts of change in image content between frames. (AVCHD uses a subset of the H.264 standard, among other things mandating a limit in recording bandwidth, which translates into a lesser ability to convey rapidly-changing detail.) The choice of H.264 comes with the requirement of greater processing power, though -- not only from the camera when recording, but also when playing back or editing videos. The more sophisticated encoding used in the H.264 standard requires quite a bit of processor power to pull it apart and put it back together again, so frame-accurate editing of H.264 requires a fast processor and capable editing program.
As with most other video-capable digital SLRs, the Canon EOS 7D doesn't offer autofocusing during video recording. Instead, you can only trigger a contrast-detect AF cycle prior to the beginning of a recording by hitting the AF button on the camera's rear panel. You can manually focus the lens during a recording, though, and the true manual operation of AF on Canon's lenses means you can do this more or less silently, simply by being careful about turning the focus ring. (We recently tested the Olympus E-P1, which uses "fly by wire" focusing, whereby the focus ring only instructs the camera to move the lens elements rather than moving them directly via a mechanical coupling. This meant that small clicks could be heard on the audio track every time the E-P1 changed the focus setting, regardless of how slowly we turned the focus ring. With true manual operation of its lenses, the Canon EOS 7D doesn't have this problem, although it's possible that a third-party or older Canon lenses might produce audible noise while their focus was adjusted.)
As we've noted in other SLR reviews, the good news with focusing for video is that you can get surprisingly good depth of field in video mode by stopping the lens down, thanks to the relatively low resolution of the video image. With a pixel resolution of only 2.1 megapixels in the Canon EOS 7D's highest-resolution 1080p Full HD mode, 0.9 megapixels in 720p HD mode, and just 0.3 megapixels in VGA mode, images that would be unacceptably blurred as 18 megapixel still shots look perfectly fine as video frames. This not only provides greater depth of field at any given aperture, but is also more forgiving of diffraction limiting at very small lens apertures. Diffraction at small apertures means you'd usually want to avoid f/16 or f/22 for still images, but again, the results generally look perfectly fine at video resolutions. Bottom line, with the EOS 7D's lens set to f/16 or f/22 (assuming you're shooting under fairly bright conditions), you'll be surprised by how little focus adjustment is needed during a typical video recording.
Many video-capable SLRs only offer automatic exposure in their movie modes, but the Canon EOS 7D gives you a choice of either automatic or manual exposure modes. In Auto mode, the camera adjusts the shutter speed and aperture as needed for a correct exposure, keeping things simple. 3.0EV of exposure compensation is available in 1/3 EV steps, to ensure exposure is as intended. Auto exposure mode is selected whenever the mode dial is set to anything other than "M". In Manual mode, simultaneous control of both the shutter speed, aperture, and ISO is possible. This is great news -- the ability to control depth of field or freeze action is very useful, giving you significantly more creative control over your videos. (Given the slow default shutter times of most video-capable digital SLRs, the 7D included, a higher shutter speed to freeze fast motion is almost a necessity for good-quality video of anything moving.) Note, though, that although you can control shutter speed, this doesn't prevent the so-called "Jello effect", more properly known as rolling shutter artifacts. Like other digital SLRs, the progressive manner in which the Canon 7D clocks data off its sensor means that sudden camera or subject movements can cause distortion, although this is less of an issue for the 7D than in some cameras.
The Canon EOS 7D's video mode is accessed via a dedicated mode switch on the camera's rear panel, which selects between Live View and Movie modes. A Start / Stop button in the center of this mode switch is used to initiate recording when the switch is in the Movie position. Setting adjustments in movie mode are made via screen 4 of the Record Menu, and again are only available when the camera is in Movie mode -- otherwise they're replaced by options relating to the camera's Live View mode. Still images can be captured in Movie mode, interrupting the movie for about 1 second. Autoexposure is used, unless manual exposure is chosen. Flash is not supported.
As compared to the video from other cameras we've tested, we found the Canon EOS 7D's video to be relatively immune to motion-induced compression artifacts that we've seen when recording in AVCHD mode (as noted, the 7D uses the broader H.264 spec). Its rolling shutter artifacts also don't seem quite as pronounced on some cameras, although they're still very evident when you pan the camera quickly while recording.
For a camera that scans video frames vertically (as all do that we're aware of), rolling shutter artifacts will be most noticeable for subjects that are moving rapidly side to side, or when the camera itself is being panned horizontally. Verticals in the scene will appear tilted to the right or left, depending on the direction of camera motion. As an example, consider the case of a camera being panned from left to right, with a flagpole or other vertical object in the middle of the scene when recording for a particular frame begins: If the top of the object was centered horizontally when the first line of the video frame is acquired, by the time the last line of the frame has been captured, the bottom of the object will have shifted to somewhere left of center: As a result, the vertical object would appear to be leaning to the right.
A typical computer these days has little trouble dealing with still images, but high-definition video can be another matter. Depending on the file format involved, it can take a pretty beefy computer to handle HD-resolution video playback without stuttering or dropping frames. The AVC / H.264 image compression used by the Canon EOS 7D is one of the more compute-intensive formats, and its 1,920 x 1080 (1080p) resolution means there's a lot of data in each frame to deal with at full resolution. The net result is that you'll want a relatively recent and powerful computer to play full-res high-def video files from the EOS 7D on your computer. At lower resolutions, the requirements will be more modest. We found that we could run the 7D's video acceptably at half size on an older G5 Power Mac with dual 2.3GHz processors, so long as nothing else was running simultaneously, so it definitely seems less processor intensive than full HD video from many other cameras, including some using Motion JPEG compression.
GoPro camera, such as HERO11/10/9 Black, will capture stunning 5K/5.3K videos, and HERO8/7/6 black will deliver hi-res videos up to 4K. But what follows is the unreasonably huge file size. For example, recording a 60-second 4K@30fps video with GoPro HERO will occupy approximately 493MB of memory. Although GoPro HERO 11/10/9/8 Black uses more advanced HEVC format to encode 4K, the file still remains big.
When we shoot a 1-minute 4K@60fps video, it eats about 529MB memory when ProTune is off, and 643MB with ProTune turned on. In addition to taking up too much space, big file will result in choppy playback and edit, uploading time to increase, and failure to send video to WhatsApp, Snapchat, Email and other programs which have strict limitations on file size and length. 2ff7e9595c
