FCP Plug-ins: Nattress Standards Conversion V2.5

For a long time, it was thought impossible to produce a Standards Conversion plugin for Final Cut Pro due to various technical challenges; when you drop a clip onto a timeline in FCP it is automatically adjusted to fit the timeline's frame rate. This poses the main technical challenge because any filter will act upon the clip after FCP has had its go of altering its frame rate. This would not be so terrible, but FCP does a really bad job of changing the frame rate - it drops and duplicates frames to make the frame rates match and this looks stuttery. What is worse, is that not only does FCP do this automatic conversion, but that it denies access to the original source media creating another technical barrier.  With the Standards Conversion plug-in from Nattress, conversion from NTSC to PAL and vice-versa is no longer a problem.

G Standards Conversion package contains two complex filters that have been designed to convert between the three standards of NTSC video (29.97 frames per second), PAL video (25 frames per second) and 24p (24 frames per second progressive). G Converter deals with the video to video frame rate conversions, and G Film Converter deals with the video to film frame rate conversions. Both plugins will correctly scale the converted clips if necessary.

Standards Conversion now comes with some useful toolkit filters that work in a similar manner to the main filters. G Pulldown Removal and G Pulldown Addition allow you to add and remove pulldown in the timeline, and G Map Frames allows you to manipulate frames and fields and produce nice slowmo from interlaced footage. G Advanced Pulldown Converter can be used to help if you've shot the wrong mode on, say, a Panasonic DVX100.

The Standards Conversion algorithms have been refined to work with both interlaced and progressive PAL and NTSC. In Version 2.5 the algorithms have been further refined to work better with Y'CbCr (commonly know as "YUV"), 10bit video and the chroma sampling of 4:1:1 NTSC DV. Additionally, support has been added to convert 60p footage from a Panasonic Varicam to 24p. In this case, Final Cut Pro does quite a reasonable job of converting from 60p to 24p, but you may find the Film Converter's solution more visually pleasing.

Both G Converter and G Film Converter work in a very similar manner. This method of working is necessary to bypass the poor in-built Final Cut Pro / Quicktime frame rate conversion and allow the high quality algorithms to work effectively. Also, if a change of clip resolution (scaling) is needed, the clip on the timeline should be nested to allow the plugin to work correctly. Again, due to limitations in FCP, the plugin must be correctly informed of the Source Pixel size of the video that is to be converted.
