    screenshots,screenshot, video screenshots

    vlc

    then tools/preferences/hotkeys/set a hotkey for Take Video Snapshot

    then tools/preferences/video and set directory for snapshots


    then use hotkey while viewing [i use F2] if you have a wireless keyboard you can do this comfortably while viewing video; and not even need to stop


    ============================


    and/or



    MPlayer comes with a very nice and easy to use video filter that allows taking single or multiple screenshots. The syntax is simple: [all formats]

    Code:
    mplayer -vf screenshot my_file.mp4

    Simply pressing the 's' key takes a single screenshot in png format in the working directory.

    but shift+S will take all frames/pictures until you hit ctrl+C


    ========================

    XBMC



    set folder settings/system/Debugging/screenshot folder

    then hit \ to get fullscreen

    and use PrtScn to get single shots

    Thanks

    I had used full screen playback in smplayer > space to pause where I want the capture > then PrtSc

    I'll try those other options to see if the quality differs

    all of these take a picture as is


    so if 640x480 it takes that ; if 1920x1080 that and so on

    the quality of pic has to do with the definition of the vid

    so they are all the same

    the mplayer trick "shift+S" is good if you want every frame ; you can even time it and then plough through the lot anyway as you say av a try

    The MPlayer command can be extended for those who like playing with such things, have a look at this wiki page:

    No problems, it is a pity that the wiki page has been forgotten... I put a huge amount of work into that one .
