Thank you very much for your reply. It worked great
However I suggest you to make this feature more visible by enabling "Show Jump Forward/Backward" by default, and by putting the configurable duration box in "Preferences > Hotkey settings". I have to admit that I would have never known how to configure the duration (which is a VERY useful setting for such a software) if you didn't help me.
What would be great is if you added extra configurable jump levels in a future release because, currently, setting frame-accurate cut points is a very tedious task when editing long videos.
For example VLC and MPC-HC allow 3 jump levels : "Very Short Back/Forw jump", "Short Back/Forw jump", "Back/Forw jump", "Keyframe Back/Forw jump" and "Frame Back/Forw jump".
Avidemux allows many jump levels as well : "Keyframe Back/Forw jump (Up/Down Arrow))", "Frame Back/Forw jump (Left/Right Arrow)", "1min Back/Forw jump (Ctrl+Up)", "1sec Back/Forw jump (Shift+Left/Right)", "2sec Back/Forw jump (Ctrl+Left/Right)", "4sec Back/Forw jump (Ctrl+Shift+Left/Right)"
Have a nice day Solveigh Team
