You get full support for the most popular video standards. The SDI and HDMI connections are multi-rate, so all models handle SD and HD television standards plus the 12G models add extra support for Ultra HD standards. Standard definition formats include NTSC and PAL. 720p HD standards include 720p50 and 59.94p. 1080i HD interlaced formats include 1080i50 and 59.94. 1080p HD formats include 1080p23.98, 24, 25, 29.97, 30, 50, 59.94 and 60p. Plus you can even work in 1080 PsF formats. On the Blackmagic Video Assist 12G models you also get support for Ultra HD formats up to 2160p59.94. On these 12G models you can even record 2K and 4K DCI rates up to 25p for digital film work!
The EOS 70D is Canon's latest entry in the HD-DSLR market, and the company is aiming to make a big splash with it, thanks to its brand new Dual Pixel CMOS AF focusing system. When Canon introduced the 5D Mark II, it stunned crowds with its video quality and price, but it lacked a big mass-market feature: autofocus during video recording. Several more recent Canon DSLRs such as the T4i, T5i and SL1 feature full-time continuous AF for video recording, but they still rely heavily on slower and sometimes-jerky contrast-detect autofocus to fine-tune focus. With the 70D, Canon has introduced its all-new Dual Pixel CMOS AF, replacing the Hybrid AF systems found in the aforementioned models with one that splits each individual pixel on the imager into its own phase-detect AF sensor, with no need to fine-tune via contrast detection. Phase-detect AF, the same AF technology DSLRs use for shooting with the optical viewfinder, provides much faster and smoother autofocus for DSLR video shooting.
Of course there are always trade-offs, and there are few small details that might deter some users from the 70D. For one, there's no headphone jack for monitoring audio, which many professionals and video enthusiasts need. Also, video image quality appears more like the 5D Mark II and 6D in terms of moiré and aliasing. Canon users who demand the highest quality might opt for the 5D Mark III if this is a deal breaker for them, though they will have to forgo full-time autofocus.
All in all, though, the Canon 70D is a powerhouse for video recording, and not only will high-end users be attracted to the vastly improved autofocus, beginners and average consumers will as well. Here's the full rundown of the 70D's video capabilities, along with our usual selection of sample videos.
The clear stand-out feature of the 70D is the new Dual Pixel CMOS AF system. Canon's previous full-time continuous video autofocus systems, called Hybrid CMOS AF (T5i, T4i, EOS-M) and Hybrid CMOS AF II (SL1), used both phase-detect and contrast-detect AF. The way this system worked was that phase-detect would get the ball rolling for focusing, then contrast-detect would take over for fine-tuning to achieve crisp focus. The downside is that this process is typically slower, plus the lens still has to hunt back and forth a bit to determine the point of best focus. This can have undesirable effects for video recording, as focus can jump back a forth if the subject moves at all in the frame during recording, and if the subject moves quickly, the camera may struggle to refocus.
In the videos below, the subject was a small, stuffed dog toy, hanging from a length of monofilament fishing line about 3 feet long. It was positioned about 8 feet from the camera and about 30 inches in front of the background poster. The arc it traveled had a maximum extent of +/- 10 inches relative to the camera position. In all cases, the focal length was roughly equivalent to a 140mm lens on a 35mm full-frame camera. The amount of focus actuation required by the combination of focal length, distance, and subject movement is probably at the edge of what you'd encounter filming a real-world subject: The little swinging toy was moving quite a bit & fairly rapidly, relative to the long focal length and relatively close shooting distance.
Canon's DIGIC 5+ image processor gives the 70D capability for both 1080p and 720p video recording. The 70D, along with all Canon video-capable DSLRs (with the exception of the $12,000 EOS 1D-C cinema DSLR and its siblings) still do not provide the option of full 1080p video at 60 frames per second, which could be a drawback for more professional shooters who need that combination.
Like most previous Canon DSLRs with video recording, the 70D allows for full manual exposure settings and adjustments including full control of shutter speed, aperture and ISO before and during recording. In all modes, except for M, the 70D switches to automatic exposure adjustments while in live view movie mode. As such, the 70D is very user friendly for both kinds of shooters: those that want a simpler video shooting experience and more advanced users who want more control over how their videos look. (It still would be nice, though, to have options like aperture priority available.)
