Sonic Pi 360° video with Denk & W.Stone [video 360°]


Some notes about the recording of this video.  The difficult thing is we all use different o/s. I’m using windows 7 at the moment, Denk is on Linux (mint) and William is using Mac os (Sierra). We all wrote some draft code that we were ready to use and modify for this recording. We had some directions but relied a lot on improvisation. For this video I was typically giving the rhythm and structure and Denk & William improvised on those patterns moves even though at some points the engine was taken over by my acolytes.

We all recorded our screens using different software and different codecs. William, on his mac, used QuickTime, Denk, on linux used [SimpleScreenRecorder], and myself on windows, [CamStudio].

On the end we had three different codecs, different file lengths, different aspects ratios.
The first step is thus converting all that mess in our format and duration to rule them all.
As in other tutorials my video toolbox is mainly composed of [VirtualDub] and [ffmpeg]. This time I also added [mp4cam2avi] to convert from mp4/mov to avi.
I now have three video streams of equal lengths, synchronised all and well.

360 degree video tutorial


Hi all ! This is my first try at a HD 360 degree video to be uploaded to Youtube.
My first goal was, as recommended by youtube to upload a 8192 x 4096 video to get the full 4K 360 degrees experience. So that’s exactly what I tried to do.  As you will see here under, that mission was more difficult than first expected.
First a little Warning : File size while working in those resolutions can be huge, especially using uncompressed video files. Check that you’ve got enough free hard drive space (> 100 Go, depending on the video length of course) before starting.Also working with such files can obviously lead to very long processing and rendering time. I included some various rendering times that might be helpful to estimate the length of the process.

Here are my laptop specs
Windows 7 64 bits
32 Go DDR4
I7 4700MQ @ 2.4 Ghz
Working on regular 1.5 To HDD 7200 r/m
