And now for a little Minecraft Housing

Yesterday I learned that the latest PiTiVi has a bunch of effects editing added to its base release, thanks to Google’s Summer of Code. I just needed to take that dope for a spin today.  It’s been a fun learning curve, but I’m not quite where I want to be just yet in terms of high-quality output (when I crack it I’l blog in excruciating detail).

Still, right now I can brighten up Minecraft night scenes (notorously poor if Youtube is a good sample-set), and do some fades, etc.  All very nice.  Here’s the end-result of the learning process.  Two house designs that have their roots in my Sandstone Islet Getaway:

Here’s “Cobblestone 11sies” (built twice on two defunct multiplayer servers *sniffle*):

And “Fletcherholm”:

The wonderful thing is that the editing is nearly invisible.  If I’m not looking out for the transitions I miss them, but they certainly make a vastly better final result than what I could have previously pulled off with PiTiVi.


OCPD? Who? Me?!?

So, I had an “umbilical hernia repair” operation last Friday to fix a hernia that has been with me since last September.  The operation has for the most part stopped me dead in my tracks from doing anything beyond sitting and sleeping. Well, I could read, but I’m just not in the right head-space for it lately.

This week, I’ve gotten a lot of daytime sleep, and a lot (alot  is not a word but, it might just be better than you at everything) of sitting done.  While I sat, I played computer games.  Quite a bit of the time was spent polishing this little Minecraft world:

I’m so sick of computer games (f**k, did I just WRITE that?!?)  that I decided tonight that I’d do that youtube video instead.  On watching it, I fear this may represent undeniable proof that I might be just a tad OCPD.

On a more work-related note, the idea of a video came out of a work thing I was doing just before the operation.  I was interested in trying differing compression codecs in video standards, because whatever is being used in camstudio AVI container, is huge.  Now, I love camstudio, and a nice little synergy-generating windows hack called Sizer, but I need to do something about that 10 minute video that needs half a DVD for storage before the boss himself demands it.

Right now, I’m leaning with using PiTiVi to do the no-hassle conversion, goofing off with codecs to see which best compresses essentially static desktop images, with a bit of cursor/menu movement between “frames” lasting several seconds long. I’ve failed yet to find a nice richly-featured video format converter under Windows that doesn’t cost well.. nothing. :-/ So, it’s a bit of fiddling between two operating systems, but I’m down with that.

Anyway, hernia repair is healing nicely.  I went for a walk in the sun for about an hour today, which was nothing short of fantastic given the week preceding it. Extended visits to places that can’t guarantee me a good lie-down are probably still beyond me, but I suspect not for much longer. If tomorrow is as good again as today, Monday will be a (possibly medicated) school-day.

Ubuntu Desktop Videos for Youtube

I’m planning on ramping up my Ubuntu desktop video capture activity soon, and uploading it to Youtube. Because I always seem to manage to forget how to do it between attempts, here are some notes for next time.

First off, capture the desktop video with [my favourite tool for the job] gtk-recordMyDesktop.  I’ve tried others, but this seems the most reliable to date. I tend to select only a single window and record that. The trick to it (which I keep forgetting) is to right-click the window you want to be captured once the “Select Window” button is pressed. A frame should be drawn around the window if it’s been properly selected. Check that audio is turned off (I’m not a great fan of my own voice so I tend to dub in some music at a later stage).

The next step is to start recording. Keep an eye out for the record button that appears on the relevant  desktop panel. When video capture is finished, press that button to stop recording. If you don’t know to look  for the button, you may not see it.  Once recording stops, the video will be “cooked” with a little status bar to show you how much is left to do. Once it is complete, feel free to save the file somewhere.  It’s an OGG video codec, so an .ogv extension is good. Take the video for a brief tour with Totem video player. Keep an eye out for anything that needs editing out, especially on the head or tail end of the video.

It’s now time to do so basic editing and file format conversion (the raw file from gtk-recordMyDesktop isn’t a codec that Youtube likes, last I checked). My favourite video editing suite is PiTiVi. It’s relatively intuitive, and allows quick, easy audio/video clip manipulation. When it comes time to render the final edited video, we need to choose a codec that Youtube will accomodate. I use the following settings:

Video Output: 1080p full HD - 29,97 fps
Container: FLV muxer [flvmux]
Audio: FFmpeg ADPCM Shockwave Flash encoder [ffenc_adpcm_swf]
Video: FFmpeg Flash Video (FLV) encoder [ffenc_flv]

And here is an example end-result:


Record long, and prosper!
