Hi
With VP version 3.12 I find that the Smart Sharpen plugin doesn't actually work with mpeg4 video clips as when the plugin is opened and one tries to configure it...Videopad crashes..(at least on my system..
) I haven't tried any other formats.
If you try the plugin with a jpg file placed on the sequence line it does work but only the presets are available. The slider controls are inactive as you have found.
These presets do work but don't seem to be configurable when selected. The choices are :
Small overall............................light sharpening...hardly any change visible in the preview screen on account of its size.
Small overall and borders........Similar
Overall.....................................Slightly more enhanced effect and works a little like an unsharp mask
Borders
Overall and borders
Mad..........................................Heavy unsharp mask effect.......too much and actually not worth using...Visible in the preview pane.
Selecting one of these options and pressing the preview button will show the effect (possibly) which may take a second or two to become evident.
If you want to see if anything IS working with your jpegs then before you add the effect do a snapshot, then add each level of the effect and take a further snapshot at each level. You can then compare the snapshots in something like Windows photo gallery when the effect should be visible as you step through the images.
Its probably better to simply add hires images to the sequence in the first place rather than try to enhance them via the plugin which, to be honest is not very effective.
