HD Video in Pro DSLr Cameras

 

 

The HD HIGH DEFINITION video capabilities of DSLRs continue to keep improve dramatically, and it’s getting an ever more important part of professional digital photography. Of the four digital cameras we spotlight in this article, simply the Sigma lacks HD video capability.

Canon EOS-ID X are able to do 1920xl080p video at 30 and also 24 fps (25 fps in PAL), in addition to 1280x720p HD at 60 (50) fps and also 640×480 SD at 30 (25) fps, all n H. 264/MPEG-4 AVC MOV format. For that first-time, you are able to make a choice from All -1 and IPB compression—/VII -1 compresses each frame for simpler editing and frame extraction (albeit with larger file size); IPB compresses frames by mention of the previous and succeeding frames, providing smaller file sizes. Mono Linear PCM sound is achievable via a built-in microphone, or you are able to connect an external stereo mic via a built-in jack, and you will adjust the volume while shoot-ng. Exposure is manual or application AE; focus is manual or phase-detection before shooting or even contrast-based before or during.
The Nikon D4 is able to do 1920xl080p full HIGH DEFINITION video at 30 and also 24 fps, and 1280x720p HD at 30 in addition to 60 fps, with mono Linear PCM audio via a built-in mic or stereo via an additional mic. There are on-screen audio level meters, and you could connect headphones to monitor audio. You possibly can focus videos manually or use single-shot or full-time servo contrast-based AF while shooting. It is possible to record uncompressed 8-bit, 4: 2: 2 video right to an external recording device via the D4′s HDMI expenditure. Especially nice is a choice of video recording crops: FX full-frame, 1. 5x DX and also 2. 7x crop. Allowing you effectively change focal lengths with out changing the lens on the camera, all at full HD quality.
The Sony SLT-A77 provides some unique video features among Digital slrs, one being full-time continuous phase-detection AF during video together with eye-level viewing. Another is a three-way, tilting exter nal LCD monitor, handy for odd-angle shooting. The newest AVCHD Ver. 2. 0 Progressive format allows the A77 to do 1920×1080 full HD video at 60p, and also 60i and 24p; the dslr camera can also do MP4 video (1440×1080 at 30 fps and also 640×480 at 30 fps). You are able to record stereo sound via a built-in mic or an additional mic, and you can shoot video in manual exposure mode or even with program, shutter- or maybe aperture-priority AE.
The Canon EOS-ID X and Nikon D4 are actually full-frame cameras; the Sony A77 is APS-C. Meaning their sensors are bigger than those of most pro video cameras and thus able to produce narrower depth of field to get selective focus and also a cinematic look that is difficult to have with more compact sensors. All offer a wide range of lenses, all of these can be used in video.
