How I do it ?

Why

Pros

– Short so simple to understand – A good way for « teachers » to reduce content to the minimal use case – Teaser for longer content like « classic » videos – Visual approach : successfull professional example for web

development

Cons

– Do not use for complex content and prefer video (See good QGIS

video content to illustrate Klas Karlsson YouTube channel or Steven Bernard QGIS uncovered channel) or textual tutorial with images like Learn QGIS

SLIDE 3

Two approaches

Capture like a screencast

– F7 shortcut in QGIS – Illustration of a QGIS « hobby » plugin behavior – OpenLayers geocoder demo

See for instance « 24 Days of QGIS 3.0 Features »

Assemble images and play with interval

– QGIS birthday GIF project

In QGIS context

Look at the article «

Geogiffery in a nutshell—introduction to QGIS Time Manager » to generate GIF using TimeManager

Use Text Annotation tool if you need some

comment in your QGIS GIF like in this Field calculator tip when working with screencast approach

Context : running on Linux

My GIF tools

Addition to display keyboard typing

– key-mon (available in repo by default) – screenkey (available in repo by default)
