Make timelapse videos with OpenSource software

As I said it in my previous post, I try to give you a short tutorial how you can make such timelapse videos under Linux. First of all, make sure that you have installed following software:

Then you will need lots of photos with a sequence. I shot every second one photo and got nearly 610 photos for some seconds of the movie. So, after you shot so many photos you will have something like this:

As you can see, they don’t really differ from each other, but later they will look really great. Now comes the part with Imagemagick. I shot my photos with my Canon EOS400D (or for the non-european: Canon Rebel XTi) with full resolution (3888×2592 px), but the final video should have 720p (1280×720 px). So I have to crop my images to this resolution. I have tried it with digikam and the batch mode of it, but there is no batch mode for aspect ratio cropping, so I have found a small script (aspect) which uses ImageMagick in the backgrond for doing it. It cropped my images perfectly with only one command. If your photos have the same resolution as the final movie then you can skip this step and follow this part now.

After cropping (or not, belongs to you) you can start kdenlive, create a new project as you like. I have decided to make 720p movies. So, now you can add a new slideshow clip.

Browse to your path of the photos (there should only be the photos for your movies, otherwise kdenlive will add those other photos to the movie, too) and adjust the settings you like. I choose a frame duration of 5ms and a dissolve of 2ms (as you can see in the screenshot), but you can set other parameters, you have to look on your own how it will look best with your photos.

Now kdenlive add your clip to the “Project tree” and you can drag it to the timeline on the bottom and have a first look at your movie in the “Project Monitor”. That’s it. Render your movie and you will get something like this:

If you are not happy with the result of your movie, you can change the settings of the movie (“Frrame duration”, etc.) with menu “Clip properties”.If you want some effects on your movie, you can drag every single effect of kdenlive to your movie and make it to something special. Now we are at the end of this small tutorial, I hope that I could help some people out there to make timelapse videos under Linux. Feedback (or critic) is welcome, just leave a comment.



wmFilebrowser – a filebrowser in a different way

Inspired by Xyne’s post I have created a similar file browser for WindowMaker. Let me introduce wmFilebrowser:

It’s a pipe menu file browser for Windowmaker where you can browse your filesystem and open files with the displayed application.

You can find the project page here.

Some words about WindowMaker

Sometimes I asking myself why WindowMaker disappeared from the news scene? I know that there were less (more or less no) activity the last years (sadly), but the activity at the moment is increasingly quite good. The new GIT repo of Carlos R.Mafra (which is not the official development repository of WindowMaker, this is located here) has initiated the development again and the developer mailinglist of WindowMaker receives emails again. ūüôā I use WindowMaker as long as I can remember using Linux, I have tested several other window managers and desktops during that time, but no other window manager has given me the feeling of WindowMaker and it’s my main “desktop” on my Core2Duo and on my small Eee 701. As you can see I’m not using WindowMaker because of his small size (I think it was about 3 – 4MB at all) or its very small ressource usage, I’m using it because it has great handling.

I have written in my last blog post, that there are some new features and bugfixes for outstanding bugs. I will try to summarize it for those who are interested in WindowMaker, because I think it’s more than worth to mention it:

  • Reduce¬†wakeups¬†to¬†zero: PowerTop claimed that WindowMaker wakeups 3-4 time/sec., it now uses the inotify mechanism
  • Switch panel in Xinerama mode fixed
  • Left¬†Half¬†/¬†Right¬†Half¬†Maximize: It¬†allows¬†you¬†to¬†maximize¬†a¬†window¬†to¬†only¬†the¬†left¬†or¬†right¬†half of¬†your¬†screen.
  • Maximus: Tiled Maximization
  • Fix¬†miniwindows¬†auto-arranging¬†bug
  • Support Xinerama in wmsetbg
  • Mac¬†OS¬†X-style¬†window¬†cycling (description here for those who don’t know how it works)
  • Several code cleanups and various other smaller and larger fixes

With all these development is going on, I really wonder why no news page has posted a news item about it. I know that the information isn’t posted on the front page of WindowMaker, but I think with a little bit reading the mailinglist you can get those information. All I can see are mostly just news about the big players on the desktop like KDE or GNOME, sometimes Xfce or LXDE, but there are not really much news about the small and very good window managers out there.

I hope that some people read this post and try WindowMaker from the above GIT repository. If you are running Arch Linux (most of the readers hopefully do ūüôā ) you can use the newly added package windowmaker-crm-git from [extra] which I have added three days ago. Further I hope that there will be some news again about WindowMaker more often than at the moment.

For those users who never used WindowMaker before, it’s different to the major desktop out there, so expect no start menu on the top or bottom of the screen. ūüėČ

Update: Martin Dietze mailed me that there is also an apt-repository for Debian (if you use it) with nightly builds of the GIT repository here.


New WindowMaker version for ArchLinux

Today I have added a new WindowMaker package (windowmaker-crm-git) to our [extra] repository. It’s compiled from the GIT repository of Carlos R. Mafra which is the most uptodate repository for WindowMaker source code. It has bugfixes for know issues and new features like Maximus which is “Tiled maximization”. There were several bugfixes for Xinerama setups and some code cleaning.

I will update the package regularly to reflect all the changes in the GIT repo. So if you use WindowMaker and you would like bugfixes and new features, install the new package and report bugs to the wmaker-developer-mailinglist, which is very active at the moment. I have tested the package and it’s more usable and stable than the windowmaker-0.92.0 package.

Doing more with my DSLR

As you can see in my Photo section I’m doing a lot of photography. Now I have began a new way to shot photos to let the photos move. Like everywhere on the web you can find those timelapse videos which are mostly generated from photos. It’s just the beginning and I’m very new to this kind of¬† photography, but I have already generated two timelapses.

Have fun watching it. Maybe I will made a short tutorial how you can do those timelapses under (Arch) Linux.
