-== Intra-frame video compression == +**Answer:** Easy, follow these simple steps:- 
-  * Most video compression is inter-frame: it exploits similarities between frames so as to achieve better compression efficiencyIntra-frame compression doesn't:  it's less efficientbut has more consistent performanceespecially for high noise and high motion video.  Setting the GOP length to 1 frame means using intra-frame compression.  + 
 +REMEMBER: PATCHES ARE SELECTABLE SECTIONS IN PTOOLS FOR YOU TO EDIT, SETTINGS ARE WHAT WE INPUT, EDIT & SAVE & AS A COLLECTIVE NAME (like for example 'Orion'). 
 + 
 +  -  Copy the two settings you want to interchange matrices from and to into a fresh ptools folder together with a copy of the firmware v1.11 bin file and ptools itself. Now open the Setting (from A to J buttons) that you want to copy a matrix TO. 
 +   Click down into ptools until you reach the section under 'Patches for Testers/AVCHD Movie Mode/Scaling Tables' 
 +  -  Under 'Scaling Tables' patches uncheck all scaling ipb matrix tables you want to change.  
 +  - Now save this edited setting to a a blank (red coloured) Settings Button labelled A to J at bottom of ptools. (to save: Shift+ click one of these buttons). Notice saving opens up a dialog allowing you to give your setting a name and details (so call it 'no matrix 'setting' or whatever). 
 +  -  Now open up the setting you want to copy the matrix FROM. Notice the scaler tables numbers and that they are ticked for this setting. Now immediately click on the slot you saved your 'no matrix setting' the one without matrices checked!).  
 +  Yes, the scaling tables are unchecked, but if you now checkbox (tick the boxes!) them notice you now have the previously loaded scaling tables patch settings in your 'no matrix' labelled setting, this is because ptools still shows the previous setting loaded in the patch if the newly loaded setting patches are left unchecked. 
 +  -  You can now resave to a new slot or overwrite your 'no matrix' slot and call it a new name like 'Setting X with Setting Y's Matrix' (e.g. 'Pictoris with Dark Matter v3 Matrix') Viola!!!!  
 + 
 + 
 +*** WARNING *** 
  
 +Substituting a different set of Scaling Tables into a functioning patch is very likely to produce an unstable patch. While the risk of permanently damaging the camera is probably small, no one can really guarantee how the camera will respond to experimental settings that haven't been thoroughly tested before. Those who choose to experiment with alterations of this type should be aware that you are venturing into potentially hazardous territory on your own. - LPowell
