As soon as your Media Pool is filled with media files, you can place them as objects into the Timeline. This is how it is done:
Click on a Media Pool category, e.g. Pictures, Audio or Video. Highlight one or several files by clicking it (.... this is identical to highlighting files in the Windows Explorer). Tip: Media files can also be dragged from the Explorer or your image browser and dropped directly into the timeline. See also Quick start via Drag & Drop.
Move the mouse across one marked file name. As soon as the mouse pointer turns into a hand, you can grab the files and move them into the desired Timeline track, e.g. an audio file into an audio track or a picture into a picture track.
If the corresponding track is not available yet or if media files are to be placed in a new track, you can simply drag the media files into the empty timeline space below the last track, and a new track is created automatically .
When an audio file or a video file is placed in the timeline as an object for the first time, Wings Vioso RX first of all renders the graphic data for the display.
Usually, the display data are stored in the same folder as the original media files. For pictures you can specify a central folder to contain the display data of all projects. This comes in handy, for example, if you want to use images directly from the archive but want to prevent the display data from being located in the image archive. See Options - Global Options - Save.
When placing images and videos in the timeline you can have them displayed in a format-filling manner by holding Ctrl and Alt while adding them to the timeline. See also Format-filling display of images and videos.
Usually, you need to drag a video file both into an audio and a video track and align it. The simpler way of doing this is by dragging the video file into the empty timeline space. This way it is automatically placed synchronously into audio and video track. This way it is also possible to drag several highlighted video files into the timeline.
It is possible to use audio files in wave and MP3 format with different sampling rates within one project. Wings Vioso RX will convert them online without you even noticing.
The resulting object can be grabbed with the mouse at the bottom edge in the 
info line and be moved along the timeline or onto other tracks suitable for this object.
Finally, you can Edit the objects.
By marking several picture files in the Media Pool and moving of them into one track in one go, you can produce a dissolve sequence. Place a track marker before you do so to limit the length of the new sequence. .... See also Marking a portion.
For picture objects you can define default values for dissolve time, change time and ramp shape... see Options - Global Options - Objects– Pictures and Allocating ramp shapes.
When placing images and videos in the timeline they can automatically be zoomed to original size by pressing the Alt key when releasing the mouse button. The reference size is the currently set screen output size. See Screen Properties.
For a more effective display of pictures in the Media Pool you can activate Lightbox View. See also Sorting on the lightbox.
You can also drag any number of videos or audio files in one go from the Media Pool into the timeline. This is a very useful feature when looking at video footing. Dragging all video files into some free space in the timeline causes one video and one audio track to be created for all the videos and for the extracted sound.
