![]() The largest certainly has the most detail, but it is also the largest in terms of file-size. The following illustration demonstrates the exact same still frame, but at varying resolutions from smallest to largest. So a 320 x 240 video contains 76,800 pixels in each frame, whilst a 640 x 480 video contains 307,200 pixels per frame. As a general principle: the larger the resolution, the more pixels there are per frame of video and data the file contains-hence the larger the file size. This is usually expressed in a paired set of numbers, respectively denoting the horizontal and vertical size in pixels (e.g. The overall dimensions of the video are what is known as its resolution. The formats that Ultranet supports in its Media Galleries are AVI, MOV, WMV, MP4, MPG, MPE, DIVX, 3GP, RM, MKV, QT and OGV. Usually, these are a paired set, so if you just stick to the most commonly used containers for web video (MP4, MOV, MPG) then you should be fine. the encoding algorithm used to code/decode the video, such as "H.264"). the package type, such as "AVI" or "MP4") and the codec (i.e. In most cases, a video 'format' consists of the container (i.e. However, there are some general concepts surrounding web videos that are good to understand so that you'll know what to tweak to get the best results (if your chosen software offers the tweaking options!).Īll of the software solutions covered earlier will produce video formats that Ultranet understands and supports. ![]() There are no hard and fast rules on creating the perfect web-optimised video, as you will always be balancing quality vs usability (file-format, file-size, universality, etc). But it may be the perfect fit if you have a large supply of FLV files downloaded from YouTube or similar and just want to get them converted to MP4 so you can view/republish them easily. Once again, you may find the lack of advanced tweaking options a limitation. Just like Miro, it uses a drag-and-drop approach to file conversion, and has a neat array of presets to choose from. This is super-simple and basic converter (similar to Miro), but being 100% focused on the Mac platform only.
