==Notes tècniques. OpenShot: editor de video==<br />
tot i que la Canon EOS 550D és Full HD, la meva targeta de so-pantall no ho és, i com que el video és una combinació de la Canon + Screen Cast, la pantalla de l'ordinador em limita el format. Com que vull un format 16:9, gravaré a 1280x720, utilitzant Recordmydesktop.<br />
<br />
1280x720 -> té una ràtio de 1,77 (16:9)<br />
<br />
la pantalla té una resolució nativa de 1280x1024 (5:4)<br />
<pre><br />
$ recordmydesktop --no-sound --width 1280 --height 720 --fps 30 --delay 10 -o armstrong.ogv<br />
</pre><br />
El so el gravo directament amb el Ardour<br />

system:capture3 -> ardour:master in 1<br />
system:capture4 -> ardour:master in 2<br />

'''Recording an old Louis Armstrong single'''<br />
<br />
Christman has gone, and I have a new camera that I want to use as a full HD video recorder.<br />
<br />
Last week I recorded an 1961 Louis Armstrong recording from LP to mp3, using my new Canon EOS 550D as videorecorder, and my new (but 8 years old) Terratec DMX6 Fire 24/96 audio interface as audio recorder. And everything using open source tools (linux OS, Ardour DAW, ffmpeg video processing). The album is called '''Sincerely. Louis Armstrong''', and the song is called '''If''', and I bought this old single years ago in a Barcelona flee market. Google thanks, I found information about the single:<br />

Decca 29421: Sincerely (Louis Armstrong With Sonny Burke's Orchestra - 1955)<br />
<br />
Armstrong, Louis (Trumpet, Vocal)<br />
Burke, Sonny (Conductor)<br />
Candoli, Pete (Trumpet)<br />
Young, Trummy (Trombone)<br />
Bigard, Barney (Clarinet)<br />
Ruffell, Donald (Saxophone)<br />
Gentry, Chuck (Saxophone)<br />
Koch, Jos Cook (Saxophone)<br />
Kyle, Billy (Piano, Celeste)<br />
Shaw, Arvell (Bass)<br />
Deems, Barrett (Drums) <br />

The resulting video is not realiiy full HD, just HD (1280x720) because the video combines the camera recording and a screencast, and the combination of screen and nvidia graphics card limits the overall resolution.<br />
<br />
The resulting wav and mp3 files have fine quality. The recording levels are OK, without saturation, and the only noise you can listen is the noise expected from an old LP recording, just the noise that some people like to listen in this sort of ancient recordings.<br />
<br />
So this video is a test of the capabilities of my Canon EOS 550D as a video camera, and my Terratec PCI audio interface as a linux compatible device.<br />
