How to shoot movies with the Canon Vixia–files sizes and limitations
How to shoot movies with the Canon Eos Rebel T2i– and “movie recording has been stopped automatically”
If the camera stops recording after a short while with the error “movie recording has been stopped automatically”, you most likely have an internal memory buffer overrun (there is a bar chart visible warning you off that shortly before the camera stops). This may be due to you not using a Class (6) or faster SDHC card. Try first a low level format inside the camera, or get a faster memory card. (Per the manual below, a lowering to standard HD should not help!).
Note also: The camera stops the recording when the file size has reached 4GB (3.99 in Windows – FAT32 limit). It is left as an exercise for the reader when that point in time is. May be related to the fact that this camera is primarily meant for photos, not video. I felt I had to use the lowest HD setting with my untested SD card (the one that buffer overran slightly later with the earlier SD card: 1280*720, 60fps – which produces 1GB/3 minute).
Note finally: camera might stop also due to overheating.

How to upload a folder with many files in Moodle 2–the ultimate training
- …using animated .gifs. Different speed? 0.25sec,0.5sec, 0.75sec, 1sec, , 2sec, 3sec, 4sec, 5sec, 6sec, 7sec, 8sec, 9sec, 10sec. 1.5sec

- And the answer is: You now can simply drag-and-drop a zip file (provided you are using a recent web browser). Start with “Turn editing on”, “Add resource”, “Folder”, and then proceed like so:
- Easy enough, but you can still save time: If your folder is reusable not only between terms, but also teachers (sections etc.), I suggest doing this in our Moodle metacourses (once).
- If you want to use an existing instead of adding a new folder, a slightly different way to manage your multiple files upload in Moodle 2 is described here.
Audacity on startup automatically selects the "microphone" as recording device…
- Which is a problem if we do not use the front microphone jack, but rather the rear input:

- Seems to be still an issue on the Group computers….
- Solution is the same as found and documented for the listening stations in relation to problems students had with how Saba Centra handles audio hardware, disable the front jack in mmsys.cpl of Windows7:

How a teacher can use NanoGong’s plugin for the HTML editor to easily send their own audio to students
- The rich HTML editor recorder plug-in is supposed to make it easier for the teacher (than other recorders that require the teacher to save to file and upload the file to a Moodle activity). Here is how it can work:
- Add an activity which includes the rich HTML editor plugin, e.g. a page.
- Click on the loudspeaker icon denotes NanoGong among the editor tools.

- A window will open that includes the recorder JAVA applet (you may have to bypass Java warnings):

- Click the red record button and speak.
- When done, click insert.
- Result:

- Note, however, that so far I have run into issues actually displaying this teacher-added NanoGong recorder content.
Troubleshooting NanoGong recorder assignments for students and rich HTML editor content creation by teachers
- Once, when submitting, I got this error? But other teachers managed to test the NanoGong recording assignment application successfully when working as a “permitted student”? That may be related to using a project site.

- If you try to use NanoGong in a browser not fully supportive of Java, you can get easily stuck:
- Firefox which has not been explicitly configured to allow JAVA applets – you will get stuck w/o the option to bypass warning dialogues.

- Chrome is not very forgiving either (here for the HTML editor plug-in):
, but you can get past it:
. - I am running into more problems using the rich HTML editor recorder plug-in which I supposed to make it easier for the teacher to provide their own audio to their students:
