Recording Computer Images for Classes

After a lot of experimentation, I found out that the best technique to record computer images is not using one of the commercial pieces of software that are currently on offer but a digital camera instead, transferring it all to the computer and then reformatting, if necessary. 

Today, I needed to satisfy the demands of Google and upload movies that respected their limits in terms of size, so that I had to grab the resulting recording from my digital camera and use Movie Maker to get the needed reduction. With the second movie, and I am talking about the blog post that precedes this one, I had to convert the image to e-mail format, what made the quality of the item decrease but kept it all inside of the limits in terms of size. 

I now take the computer to be simply another world object, so that we can record what goes in it in the same way we record other things. The evolution of the techniques for building screens and machines now allow us to do this sort of thing. It gives a lot of work and it is very hard to do it if we are on our own but it is feasible and you can see the good results on the previous post, inside of this same blog.

Voice and Powerpoint

You probably have faced the situation of not being happy with the recording you have for your Powerpoint presentation. It is not very easy to find a way out of that.

Basically, Powerpoint creates an icon and gives you the opportunity to give a name to the recording for each slide, so that you can use that resource a bit better than you currently do: Name all recordings in a unique way. Then use the search button from MS (the rectangle that is found to the side of the MS button) to find the file. Click on open file location after right clicking over the name, which will appear at the top of the rectangle that is built over the MS button after you press enter on the search bar. 

You then convert the file, if necessary, or you record the message using the Voice Recorder from your computer. You can even use iTunes to rename the extension of the file, as we have explained here earlier on (will give you a .wav). You then drag the file to inside of Audacity and perform at least these actions: Leveling, Noise Reduction, Equalizer and Normalizer. This sequence, per se, will give you a much better quality of sound. You then must export the file to be able to insert it in your Powerpoint presentation. You will use the resource Insert Audio in this case. 

Audacity is a free program.

Embedding Movies in POWERPOINT Presentations

Ever had problems with it?

Today I faced the ultimate in these regards: I even had a .wmv but THE THING would not cooperate. No, sir: It kept on telling me that the codecs whatever. 

Oh, well, Google comes, Google goes, and I found something of interest that came from the own Microsoft (MS). Shame it did not work as they said it would, so that I went to the page they told me to visit, for third parties' CODECS, and downloaded absolutely everything that seemed to be even remotely related to my problem. After that, I installed everything, even something with the Communist flag on it, with no fear (what we should never do) and... and...: Yes, that's right, FABULOUS OLD NOTHING!

I finally dug to the right side of the Google Universe and found a gem: All, second choice, XP Codec Pack, and, if your problems are of the same type, you should be just fine (the MS message was install codec or Apple product x). 

These guys have all codecs inside of this single batch file, so that you click install and it all works as if you had a Genie.

Free Conversion: Movies

Sometimes you just need to convert .mp4s to .avis, right? The problem is then finding a reliable program through which you can do that. Most of what is available is going to cost you.

I found this website, however, where you can convert all for free and the output is of reasonable quality. It is probably not acceptable for most of what you want to do but if you are going to use the movie in a Power Point presentation, it should be something. 

Convert

Itunes: Free Conversion

So, I had this musical file in .m4a shape. My computer was going crazy and there was no way programs would converse. They finally decided that .m4a was too advanced for them in an incredible programs insurgency. 

And now?

Google goes, Google comes and I watch: Jee, it is going to cost me a lot if I want to be serious about this.

Finally, a friendly approach: Just use Itunes!

I had Itunes, I did not pay for it, and I converted it all in a way that all my programs became happy and therefore in a way my computer became OK again. 

We change a setting only but mine was already to what I wanted and Itunes converts to .wav upon receiving the order to import music from somewhere. After that, all you have to do is right clicking on your musical item and choose Create WAV Version.

Wow, what a miracle in terms of simplification and costs!

Power Point and the Sound Icon

If you have ever faced the situation of wanting your sound icon to disappear from your Power Point presentations, then you will find value in this information.

Due to the clever programming systems in place these days, most of the things done in IT are object-oriented. In this case, you can drag items from your screen quite easily: Just click on the sound icon and drag it to the edge of the screen where the slide is. This will suppress its image when it comes to both .pptx and .wmv presentations, so that you won't see the icon in both cases (movie and slides).

You could also go to the right rectangle of your screen, where you see the list of extra elements on your slide (if you have it on) and right click on the arrow. In this case, you will see the option Hide the Icon. Just tick that box. If that doesn't work, you can reinstall your Power Point. Notwithstanding, you may be a victim of hacking and malware, so that reinstalling the program won't work. You should then run good anti-hacking and malware programs over your version of Power Point.
