[jjd-uk]

Thanks for the suggestion but I'm not looking to edit video.  Kodi easily captures screenshots as it is.  I just want to use Kodi frame by frame so I can capture more precisely by pressing Alt + Left/Right arrow keys.  It doesn't work for me but according to posts I read here it does for others.  Maybe they are using a different platform and the Windows 20H2 I use is problematic?  Maybe something has broken functionality in the latest Matrix build?  Maybe there are settings in Kodi that require they be enabled or disabled beyond the Sync Playback to Display?  I don't know?  That's why I'm seeking help here but a 3rd party software is not what I'm after tbh.

Frame Advance

You seem to be getting confiused, those Alt + Left/Right arrow keys controls are only for the tempo playback speed feature, this is not frame advance. For frame advance then PlayerControl(FrameAdvance(1)) needs to be added to the keymap. However if you use Estuary then the ability to do this from the skin with no modfications is now possible in v19, first you must pause the video, open the OSD player controls, press up so the nib chages from white to blue to show it's selected, then right arrow can be used to advance.



Note: video must first be paused to use frame advance (sync to playback does not matter for frame advance).

Tempo/Playback speed

Should also mention the tempo/playback speed can also now be controlled via the OSD gui in v19





Note: sync to playback needs to be enabled.
