Youtube stores whatever you upload and transcodes to other formats using their own versions of multiple compression formats including h.264 and webm. All transcodes go from the same original file that you upload and are stored after transcoding. Youtube may change the options used from time to time and save new encodes of the video. Encodes are generally ...

My guess, what you are seeing is most likely the result of the better color detection and processing with the sensor and image data and the better depth of field provided by a high quality professional lens. There is far, FAR more to image quality than simple resolution. The color accuracy of the sensor, the dynamic range, shadow detail, vibrancy and ...

Well you CAN make rough assumptions. For a live action film a bit-rate of 3-8 Mbit/s is very advisable at 1080p. At 3Mbit/s you will very likely have noticable artifacts, thats usually an advisable bitrate for 720p video. A file at SD resolution 480p/567p that is around 4GB in size you probably deal with a DVD that wasn't trans-coded for archiving. Which is ...

I would go with either jing ( http://www.techsmith.com/jing.html ) free or Camtasia ( http://www.techsmith.com/camtasia.html ) both from Techsmith. Camtasia allow you to zoom in on part of the screen after recording but before rendering. This basically solves your problem and is great when you need to create video to a resolution that is less than the ...

There is no concrete answer to this. It depends entirely on the content of the video. Video compression effectively looks for patterns in video. If lots of patterns can be found, then high compression can be achieved with high resolution and low but rate. If the video is hard to find patterns though, then high compression results in altering the video to ...

That's very strange. Normally, video files with higher resolutions have a bigger file size. That is, if the videos have approximately the same duration? If they do, the only possibly explanation are very strange bitrates, which might cause this. Even so, I would go with the 1080p file, since a high bitrate doesn't really result in better quality for 480p ...

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 ...
