Animated gif without a jump

I like my animated gifs to be without any jump when the animation starts all over again. This is especially difficult to achieve when you’re using a short part of an existing movie.
I often use the trick of reversing the clip in iMovie.TripToTheMoon_animated

As part of the Daily Create Assignment TDC1541 of the ongoing online course DS106, I made this animated gif of a scene of the movie “Trip to the moon” of 1902.

I used the following tools:
QuickTime to record the movie on screen
iMovie to cut the captured movie and to reverse the clip
LunaPic to make an animated gif plus to add a caption to it.

First I located the movie on YouTube and watched it to see what scene I would like to use for my animated gif. I choose the scene where the scientists see their moon capsule for the first time. Schermafbeelding 2016-03-28 om 18.47.59Then I started the screen capturing tool of QuickTime by right clicking the icon in the bar and picking “screen capture” (in Dutch it reads “Nieuwe schermopname”).

After recording a little bit more than what I needed for my clip, I saved the movie clip.Schermafbeelding 2016-03-28 om 18.48.27

Next I opened iMovie and imported the movie I just saved. I cut away the parts I didn’t need and then copy/pasted the clip in iMovie.
To reverse the copied clip, I highlighted it and clicked the turtle symbol in the tool bar in the right upper corner. There I clicked “reverse” (in Dutch “keer om”).

I saved the result to a file on my computer and went on to Lunapic, an awesome free online tool to manipulate images, video and gifs.

In Lunapic I choose “video to gif” and uploaded my clip. I added a caption using the option “add a caption” and saved the result to my computer.


What’s in your jar?

Yesterday I got challenged by Laura Ritchie to reply to a tweet “What’s in your jar?”

This is what’s in Laura’s jar. #YourJar

She explained more about this challenge on her blog where she also presented the contents of her jar. The challenge originated by the idea of Chrissi Nerantzi as an in-person activity for the 2016 UK National Teaching Fellow’s Symposium.






I had to give it some time to come up with what would be in my jar. But here it is.


Passion would be in my jar because as a student, as a learner, it’s your passion for a certain topic that gives you the energy to learn as much as you can learn about that topic. This learning could concern knowledge ( “I really want to know how this works!” ) and/or skills ( “I really want to be able to do this!” ).

Searching skills would be in my jar because we live in a time with an abundance of information. To find the information you’re looking for you have to have the skills to use the tools for searching. Those can be digital tools, language tools, but can also be knowing the right people to ask.
Next to that you have to have enough knowledge to be able to recognize the answer to your question.

Writing skills would be in my jar because you’d not only want to keep track of the answers you’ve found. You’d also want to share your knowledge/skills with others, just like millions of other are doing right now through the internet.

On the topic of knowledge I made this interactive module
