How apply FF on video in Photoshop ?

By default FF will only apply the effect to just one image (in this case one frame)and will not continue with the next frames as it does not have batch processing.

I have never used the "EnableAllPluginsforSmartFilters.jsx" so I can´t help, but does this work on just one image (or frame)?

Possible solutions

1 - If you can apply FF to one Smart object you could make an action inside photoshop to batch`process all the frames of the video.

2 - If you have Windows, you can use the awesome and great Batch Processing tool done very well by aba shown in this thread --> FF Batch Tool for Windows

It works very well although the big problem is that this will not work inside Photoshop, so you will have to use photoshop to separate ALL the single frames from the video into a folder and then process that folder with the FF Batch Tool
