Making a movie of a timepoint sequence in Volocity in three easy steps!

This month I am going to show you how to create a professional looking movie in minutes which steps through all the time points in a multi-time point sequence.

Volocity has a huge range of movie-making options which I regularly use to make stunning movies for presentations and publications, however in this tip I want to show you the most basic level of movie making - making a movie which simply plays through a timepoint sequence which you have captured. Give it a go and see for yourself how easy it is:

Open your image sequence and configure the Image View (shown below). You can create a movie from any of the Image View modes such as 3D Opacity, 3D Planes, XYZ, etc and you can add scale-bars, timestamps or anything else that you would like to show in your movie. If the timepoints in your image sequence contain more than one z-plane, then it is often a good idea to use the Extended Focus view mode, which displays a single image by making a brightest point merge of all the z-slices in the volume.

Right-click on the item in the library and select 'Export...' from the File menu (see below). Name the file and select a folder for the exported movie. You should then select one of the 'View as...' options, e.g. "View as AVI Movie", "View as WMV Movie" or "View as Quick Time Movie" (if you have QuickTime installed on your system). By selecting one of the 'View as...' options, as appose to the 'Item as...' options, this will allow you to create a movie which displays everything that you have configured in the image view (such as your timestamps, scale bars, etc).

Note that for whichever format you choose, you can then click on the options button to the left, which will give you additional output options. For example, if you choose “View as Quick Time Movie”, then you can select the compression codec and quality, and the timing that you require for the finished movie. When you are finished, click ok.

The Compressor type and the bias towards a Smaller File or Better Image will affect the size and quality of the file created. Generally speaking, either Apple Animation or the Sorenson compression will provide a good balance between quality and file size.

Finally, click export on the Export File dialog box and your movie will be made.

So, in summary, when working with an image sequence which contains time resolved data, selecting export from your Image View (in a ‘View as…’ format), will allow you to make a  simple movie of that view stepping through timepoints.

It really is that easy!
