Your laptop's screen resolution may be 1600 x 900.
Change the resolution, before recording, so that it's 1280 x 720.
If you are connecting to an overhead projector then your screen resolution may drop to 1024 x 768 (and this is what you should use when producing the videos below).
Start your document camera (the camera needs to be plugged into the USB port of the computer ;-)
and set the resolution of the camera to 800 x 600.
Make sure that the AF (auto focus) is not in the continuous mode (C), there is a switch on the camera head (move it to S, single).
If the camera is in the C mode then every time you move your hand under the document camera it will change focus, which is a problem when trying to focus on the lecture notes.
Position the camera and then hit the focus button on the camera head to focus on the lecture notes paper.
When running the doc camera in the full screen mode simply left click on the display to toggle the on-screen menus on/off.
Next plug your headphones and microphone into the laptop.
Camtasia 8 setup (see here for some older information)
Start Camtasia Recorder
Test the volume, making sure you use the headphone's mic and not the computers (unless echo is okay for your recording)
Select the area, if you are using an overhead projector (e.g., in a classroom) your screen is likely at 1024 x 768
For the remainder of this setup we'll assume that you have set your screen to 1280 x 720 (which is what I use when recording lectures in my office)
as a good trade-off between video file size and resolution. This size will also work well when others are viewing your videos using their high-resolution displays
Under Tools -> Options -> Inputs set the Screen capture frame rate to 3 (to keep the file size small...very important if you are uploading the videos)
Note that if you want the videos to be less jerky then you can increase the frame rate at the cost of file size
Hit the red rec button above to start recording
When finished hit F10
Next you can select Produce, below, to produce your video
However, if you are teaching courses (recording lectures) back-to-back you'll have to produce the video later so
hit the arrow below Save and Edit to "Save As" the *.camrec file of the video you just made (what you'll produce
for posting on the web later)
Now you can record another lecture by pressing the red rec button
Below shows where the *.camrec file can be saved
To produce a video (at this point you have your *.camrec file(s) so it's okay to close Camtasia Recorder) start Camtasia Studio
After starting Camtasia Studio select the center icon below, that is, "Import media" or File -> Import media (or Ctrl+I) and import the *.camrec file
Next drag it down (with the mouse of course ;-) to the bottom of the studio as indicated below (or, for smaller screen resolutions where you can't see
the portion of the screen seen below, right click on the image and select "Add to Timeline at Playhead")
After dragging the file down the following window will pop up
Set the dimensions to 1280 x 720 (the size that we recorded...unless the projector set it to 1024 x 768 as it does in my classroom lectures)
After hitting OK click on the "Produce and Share" icon (or the menu items File -> Produce and Share)
Select Custom production settings as seen below.
Hit Next > then MP4 - Flash/HTML5 player as seen below (best for posting)
Hit Next > again to get the following
Select the size tab and set the dimensions back to 1280 by 720 (what's up with the 721??? ;-)
Then hit video settings and set the Frame rate to 3 (you did this earlier too...again, important for small size videos)
3 frames/second works fine for lecture notes but you may want to increase the rate if recording a board lecture (someone standing and the board lecturing)
Hit Next> again
After hitting Next> again we get the following.
Enter the name of your video
I always use the same name as the *.camrec file to reduce the burden on my memory ;-)
Hit Finish to start the production.
When Camtasia Studio finishes generating the video there will be a folder, here for example, called lec2_ee320_video.
Within this folder is an html file called lec2_ee320_video.html that you can link to, after you have uploaded the folder, to run the video.
Hope this was useful!
Start the Camtasia recorder
Adjust the microphone volume, click on audio adjustments for further help.
Note that this step, ensuring that the microphone is connected and the volume is set correctly, is VERY IMPORTANT!
Next click on Camera options, above, and then Video, below.
Set the screen capture rate to Manual, 3 frames/sec (to keep the video file small).
Hit OK and then select the entire desktop by hitting "Select Area to Record" and then clicking directly on the desktop, not an open window including the doc camera window.
Since you've selected the entire desktop the width and height of the recorded area should be 1280 x 720.
When finished hit F10, or F9 to pause.
You can also click on the red flashing Camtasia icon on the task bar to stop recording.
Save the video as a *.camrec file, here we save it as example.camrec.
Next select "Produce my video in a shareable format" as seen below and hit OK.
Convert the example.camrec file into a format that can be played in a web browser.
At this point you can change the laptop's screen resolution back to 1600 x 900 (which is recommended).
Further reduction in the file size can be achieved by reducing the audio and video quality.
I find that mid-range is a good balance between quality and file size, as one would expect.
Select the name of the video, here we select the same name as the *.camrec file.
The last step is to start converting the
Below shows the location of the files.
Link to the example.html file seen below (move the entire "example" directory to your website) then link using, for example:
Using this technique the size is roughly 6 MB/1 minute of video, much less if you don't use the document camera much.
The raw, *.avi, files are stored in a directory located in C:\Users\jbaker\AppData\Local\Temp (for example).
This is useful if the computer crashes and you have to manually convert, using Camtasia Studio, the *.avi files (of course you can watch the *.avi files directly but they are huge).
It's very important, if you are making a series of recordings, to delete the files every so often (after making backups of what you care about on some external storage media) in (for example):
C:\Users\jbaker\AppData\Local\Temp (where the temporary video files are stored) or C:\Users\jbaker\Documents\Camtasia Studio (where *.camrec and the production videos are stored)
These files can be huge and fill up your hard disk (THIS IS IMPORTANT!) since the failure (your HDD becoming full) can (will) happen in the middle of a recording.
