Set swf file dimension

Working with Omeka for first time. Have swf file created at 800 x 600 pixel dimension.
Has been added as an 'Interactive Resource' type.
On exhibit page they are shown at 710 x 530. Where is this display dimension set?


Generally it auto-detects the size, but my guess is that displaying the full size of the video at 800x600 conflicts with the layout in the exhibit page and the theme, so it is getting slightly resized.

The public display of items and text on pages is controlled by the page layout and its exhibit theme.

You can modify this by editing the layouts and/or theme CSS found in plugin's directory:

Or, you can try another page layout that might work better.
