CamStudio is a well-known free screen capture software. I used it, but didn't like it. Movavi suite has screen capture and video editing features, but it's not free. To get best results, you should use quality screen capture codec, not resize your source videos, use good video converter or editing software. Adobe Premiere Pro is a professional video editor ...

In order to get a near the high quality you require, you would have to use quite a high bit rate. Unfortunately the number of pixels that the video decodes to and the actual effective resolution of a video are not the same thing. Modern video compression will make the most effective use of the data rate you set the video to use, but the more you ...

Ok, I've found the problem. I have tested with another lens (Sigma DG 70-300 f/4 - 5.6 Macro), and the result is much much better than with default lens. But I am not able to explain this.

Most topics have been very well discussed already, I just want to add a case were even more than 400hz is very much needed. As previously stated by Oddthinking, the eye and human brain don't work like a TV or Camera. This especially counts for cases where our other senses are involved. E.g. video games, high-frame rates of 60-120hz are very well perceived ...

As a gamer, I notice a huge difference between a regular 60hz monitor and a 120/144hz one. The smoothness of fast movements is impressive! BenQ L2420TE Asus VG248QE EDIT - Televisions have input lag, so it doesn't feel as smooth as these monitors.

The reason why modern TVs have been pushing higher framerates is not because people can see much beyond 30-60Hz, but because if the source framerate and the display framerate doesn't match exactly, then the display has to either drop frames, or add frames. This mismatch is visible, particularly during panning scenes, for instance. It used to be that ...

A similar question (except about 60Hz) was raised on Skeptics Stack Exchange. The answers there discuss how the human eyes works differently to screens and cameras, and doesn't have a frame rate, and that being able to distinguish flicker and being to perceive that we distinguish it may be separate concepts.

No, there is no practical limit that we know of yet to what would be best, there is however a practical limit to what we can capture and display. In tests with airforce pilots, subjects were able to identify a plane from being shown a frame for only 1/220th of a second.1 They eye is able to pull information out of extremely short periods of time, but ...

As per my knowledge television sets are clocked to 60 hz refresh rate. As it goes on increasing like 120 Hz the pictures will look more smoother. but lets say for 200 performance will enhance a bit. But for 600 Hz or so our eyes will not feel much difference than 200 Hz. So as per my opinion its not necessary to have refresh rate as high as possible in ...

Wanted to chime in, Did you know that Bentley Motors ad, was filmed using an iphone. Using an iphone 5s to sell their $300,000 car. You heard right. I was quite surprised. Below are the details. Here is the commercial (after 3:15 mark you see behind the scenes footage) ...

There are already 2 great answers, I just wanted to add some input that would be too much as a comment. Firstly it highly depends on which iPad you own, the camera in the first 2 generations were "garbage". I think that changed a bit with the iPad 3 and iPad Air. If the quality of your iPad camera doesn't produce suitable material you can stop right there, ...

Trade in the iPad and buy a desktop or laptop that you can edit on. You will not produce professional results entirely on an iPad. I am not aware of any good video editing options for iPad, certainly none of the big names have a product available. There simply isn't enough horsepower on a tablet to perform the hard, complex operations involved in video ...

There are plenty of camera apps in the app store that will let you lock of the exposure and focus of the iPad's camera. These are the features that I'd consider most important. Locking focus and exposure keeps the camera's settings from "breathing". This forces you to think about focus and exposure before you start shooting. This forethought is the ...

No most video formats (nearly all) do not allow custom ICC color profiles to be embedded. most video on the consumer end is intended for the REC.709 color space. sRGB is similar and uses the same primaries. transcoding (including compressing) will almost always result is a slight shift in color accuracy, saturation, gamma curve, or black and white level ...
