Hi, I applied a videofilter to an .avi and saved the project in .trk file. (radial distortion if it matters) So far so good, but reading this .trk project gets stuck at 95% Deleting the following lines at least helps to read the file without a filter.

<property name="filters" type="collection" class="java.util.ArrayList">
<property name="item" type="object">
<InvalidTag class="org.opensourcephysics.media.core.RadialDistortionFilter">
<property name="fixed_radius" type="double">1.0</property>
<property name="input_type" type="string">Equisolid</property>
<property name="input_fov" type="double">1.43116998663535</property>
<property name="output_type" type="string">Equidistant</property>
<property name="color" type="object">
<InvalidTag class="java.awt.Color">
<property name="red" type="int">0</property>
<property name="green" type="int">255</property>
<property name="blue" type="int">0</property>
<property name="alpha" type="int">255</property>
</object>
</property>
</object>
</property>
</property>

Is there a way to get debug output? kind regards
