FullHD video on a DSLR?

Question

Video

I hope the question will do without holivar. It is advisable to bypass the topic of the reasonableness of shooting video on a DSLR.

I had a Canon S5 IS soap dish about 5 years ago, I bought it for 12tr. Oltically shot video at the declared resolution of 640x480, the video was clear, the specified resolution was “honest”.

Now I bought a Nikon D5100 in which the video is declared 1920x1080, but no matter how hard I try, I can’t shoot a clear video with FullHD resolution.
By changing the size of the clearest freeze frame from the video in Photoshop, trying to achieve clarity, I reached a resolution of 800x450. This is the resolution at which the freeze frame became clear.

Here, in fact, a question arose for you: Can you tell me a DSLR with the ability to shoot video with an honest FullHD resolution (that is, one on which the picture is clear). It is very important that the price of a camera with a lens should not exceed 50 thousand rubles.

Answer 1

The Nikon D5100 should have everything “honestly” with FullHD resolution, perhaps the “fuzzy” video frames are to blame for the fact that you had a low shutter speed set (see, for example , a lesson about shutter speed on Vimeo ).
In general, if the goal is to shoot video, then Canon cameras are traditionally more suitable for this. For them, there is a special Magic Lantern firmware that makes it easier to shoot video.

Answer 2

Some time ago I switched from a Canon Legria HF S21 camcorder to a DSLR (I shoot small videos, “not home” use). It is immediately noticeable that the quality is much higher. Light sensitivity is high. Moreover, shooting is convenient: a lot of hard buttons, a large focus ring, all the settings. Do not compare with the touchscreen.
I use Canon 550D kit. I am attaching links to several screenshots from the video [email protected]
Video frame: A photo compressed by Photoshop to 1920x1280: More frames from the video: Almost all screenshots with very poor lighting :( But you can evaluate the sensitivity.






Shutter speed greatly affects video clarity. If you need mega-clarity, then the shutter speed should be set shorter, 1/125, for example. But in reality, this is not required in the video, since a slightly blurry image is more pleasant to watch. Watch any movie, it's like that everywhere.
In the internet I saw a comparison of 5D and 550D in terms of video. There is almost no difference, only 5D has an even larger matrix => photosensitivity at a height.

Answer 3

Canons are the most popular in DSLR video and at this budget you can afford a Canon 7D or even a full frame Canon 5D Mark II and I think you will be happy with their videos

Answer 4

By changing the size of the sharpest freeze frame from the video in Photoshop, trying to achieve clarity, I reached a resolution of 800x450. This is the resolution at which the freeze frame became clear

Greases, shake .
Your resolution is 1920x1080 and maybe honest. But “exposure” is something (in relation to video - how long it takes for one frame), in poor lighting it can be 1/25, and when shooting handheld or shooting moving objects - this is “repin’s picture - sailed”.
For the test - put the camera on a sunny day on a stationary object and shoot a video - then pull the frame from the middle and look.

Answer 5

Why do you need a freeze frame?
Buy a device that can adjust the exposure when shooting video.
In good light, a fast shutter speed will give you a clear freeze frame picture.
But such a video usually "strobes" when viewed - the change of frames becomes visible to the eye (at FPS close to 30). But this is important depending on the scene and the plot. For example, often for a dynamic scene it is better to slow down the shutter speed so that the frames are blurred.
Well, about the focus correctly already wrote above. The camera must be able to quickly refocus during shooting. If she doesn’t know how to do this or knows how, but not quickly, you will have soap.
It depends not only on the camera, but also on the lens.
With such a budget, I would look at the 550D / 600D line + a good ultrasonic lens + special firmware.

Answer 6

Not for the sake of holivar, BUT when I was choosing a camera for myself, I also thought I could take a DSLR, etc. ... I found a huge topic on the ixbt.com forum about this, looked at examples, etc. ...
Advertising is all godless advertising and a scam.
If you want a good video take a camera.
If you want a cool artistic photo, take a DSLR.
It's like TV…
do you want to read texts? to connect monik? take LCD
want to watch movies, sports? take plasma

Answer 7

Another possible reason (the rest, such as a long clipping, have already been named) is compression artefacts. Video formats, as well as the devices for shooting video, are not designed for the “freeze frame” mode.
