Devon and others, I have redone screencast reviewed by Devon. Btw, thanks very much, Devon for your comments which spurred me to get help from the Screenium support unit.
There were several small issues that I needed to adjust before I could achieve technically good video and audio quality. For me the most annoying problem was the lack of synchronization between video and audio and I am still a little disappointed with the video quality. But the support person told me to export the recorded videos in formats that are not standard because he has found that the nonstandard settings better match Youtube's software. So, I exported the newer video with jpeg compression and 425x318 size, not the default H.264 compression or 1024x768 "current" size, and for the audio to use mpeg4 at 30fps. I am not quite sure I am using the 30fps because a couple of times when I forced 30fps the upload file ballooned to 150+ mb and it looked liked the upload stalled. So I let the software determine the fps. I also increased the font size of J to 18 from 12 which I myself use and I think the text in the ijx and ijs windows are more readable. I don't know how to change the font size of native J menus, for example, but that would be an improvement, I think. As to my low voice, I am not sure I can change that without a lot of practice because a louder voice tends to make me more anxious. But I will try to speak louder. Speaking is very guarded for me, because I often block on words, and my speech is not that clear. The robot is very minimal, as Devon observed. But the robot matches my implicit philosophy for this demo, and maybe for many J demo's, that they should be teasers and simple to attract new users, because for me the joy of J has been puzzling through the programming and searching for programming solutions, with the help of the forum and the great resources. So for me the screencast demo's would mostly be targeted to showing ways to make the work flow easier and more effective to people new to the J environment. I am assuming that lots of short screencasts are superior to fewer long ones, especially because Youtube states their preference for limiting videos to 10 minutes. But also, because I think it may be difficult for a viewer to maintain attention for longer times. Well, I am going to leave the original screencast on Youtube for a while, but I believe the "... (again)" replacement is better. http://www.youtube.com/watch?v=Iw6F-6jh5WA On Mon, Mar 16, 2009 at 10:52 PM, Devon McCormick <[email protected]> wrote: > Brian - this is a good start though you really didn't get to the "robot" > part very much.
