![]() ![]() The value of alpha in the color code ranges from 0.0 to 1.0, where 0.0 represents a fully transparent color, and 1.0 represents a fully opaque color. Alpha:Īlpha blending is a convex combination of two colors allowing for transparency effects in computer graphics. ![]() The undesirable jagged or stair-stepped appearance of angled lines in an image, graphic, or text. The Principal video that is usually someone speaking. Please let us know if you need a term defined by These definitions are a work-in-progress. Becoming familiar with these terms only makes your job easier. Here is a list of terms commonly found in videoĮditing. Like most industries, video production hasĪ language all its own. If you find yourself wondering what a video production term or an acronym These actions are not as easy to perform in Pitivi.There is much technical terminology in today’s fast-moving media-centric world. The context menu is also used to turn off the video image and mute the sound. Instead, you must open the context menu for the element, choose Properties As with the length of a clip, you cannot adapt the length of a transition simply by dragging the edges of the bar in the time line. A small cog wheel next to the preview image indicates that the clip includes an effect. In OpenShot, you can drag transitions and effects from the corresponding tabs onto the desired clip in the time line ( Figure 6). Practically speaking, working with OpenShot proves somewhat less convenient than working with Pitivi. Scissors may actually be required or the user can set the length in the clip properties on the time line. Moreover, putting the desired segments together in the time line is not easy. This feature complicates the process of cutting a clip in correlation with the sound. Unlike Pitivi, OpenShot still displays a bar without audio track but with several thumbnails of the video. Like Pitivi, OpenShot uses drag and drop to move clips and audio tracks from the library to the time line. The third area contains a media library organized with tabs and a large selection of transitions and effects. OpenShot, however, arranges the tools needed for editing above the time line. The time bar and the window for the video preview will be familiar from Pitivi. OpenShot divides the editor window into three different areas. Also, it does not have the same customization features. With respect to operation, the programs work almost identically to one another ( Figure 5).įigure 5: The interface for OpenShot version 2.0 has been switched over to Qt, making it appear more modest than the Pitivi interface. (See the "Installing OpenShot" info box.) This change gives OpenShot a flexible layout similar to the one in Pitivi and makes it possible to take operating elements out of a window and transfer them to a second monitor. Also, version 2.0 of OpenShot, which is currently available in Beta, has switched to the Qt interface. ![]() Unlike Pitivi, OpenShot relies, just as does Kdenlive, on the MLT Multimedia Framework instead of on the GStreamer libraries. With other test projects, Pitivi interrupted the export with a message stating that there had been a "general error in the data stream." OpenShotĮven though OpenShot and Pitivi look similar at first glance, they are actually very different. Pitivi rendered some of the clips successfully but it attached audible artifacts to the end of the video. ![]() The results of this process proved unreliable in testing. The time required to finish this process depends on the length of the video and the effects that have been embedded. An assistant then helps select suitable codecs and settings. Pitivi will automatically switch to the correct tab.Īfter completing all of the work, you can export the video by clicking on Render To subsequently modify a piece of text, select the text in the time bar. Just as with a clip, you can drag the title to the desired track and extend it to the desired length. Pitivi will then automatically deposit the title at the end of the time bar in the track that has the longest run time. This is done by selecting the generateīutton and then switching into a simple editor for constructing the text. Figure 4: To add a cross-fade, you can arrange two clips in a track such that they overlap and then select the overlapping area.Īs a final option, Pitivi offers the possibility via the Title ![]()
