Who's compressing my JPEGs: Gmail, iPad, or WordPress?

The other day I discovered that some JPEGs I'd posted to my (self-hosted) WordPress blog had been compressed. The subject of my blog happens to be anaglyph 3D photos... and if the images are not saved at a very high resolution, a phenomenon called "ghosting" or "crosstalk" appears, where parts of the image that are only supposed to be visible to one eye are visible to the other eye as well. This can ruin the 3D effect. So it's important that my images are uploaded and posted with no added compression. The problem is that I don't know exactly where the problem occurred. Details below...

Batch Changing iTunes BitRate for Existing Songs W/O Making Copy

So, I definitely want to convert all my high bit rate mp3 songs in iTunes to a lower bitrate of 190. I have the bit rate setting changed in iTunes, and I know when I right click and choose "make mp3 copy" it does exactly that. BUT, I don't want the original around anymore in iTunes and don't want to manually go through and delete them or go into the folder to do that. The threads I have looked at tell me how to do the first but don't address the issue that I still have the higher bit-rate copy in iTunes. I have a lot of music, I don't want the higher copies cluttering it. (I have a backup of the originals anyway). Is there something I am missing so it just lowers bitrate but doesn't make it a copy?

How to compress a line graphic video

Any video compression mavens in the house? Is there a specific codec which excels in compressing line graphics? I'm trying to compress three videos for the web. The first two look fine, but the third looks absolutely awful. The ones that look fine are filmed, with actors; The one that looks terrible is entirely comprised of a line graphic and scrolling text. Upon compression, the bottom half of the screen looks blocky and jumbled... See here (uncompressed at right, compressed at left). I used H.264 encoding and 700 kbps, as instructed... But I also experimented with higher bit rates and quality, to no avail. [more inside]

Smallest possible audio file to make a 440hz tone?

I want to create the smallest (file size) possible audio file that, when repeated, will sound like a given note (e.g. 440hz A). I think this needs to be just the length of one wavelength, but I'm not sure how I translate that to a length of time, or if the smallest audio format is one in which note duration doesn't matter. I don't care if this tone sounds artificial, but it needs to play natively in Firefox, Safari, and Chrome browsers. Is MIDI the best (most compressed) format for this or should I use something else? And what (ideally free) software might I use to create the files, given access to OSX and Windows XP?

Which camcorders let you turn off all the clever stuff and access the raw video?

I'm thinking of buying a camcorder. My requirements are slightly unusual: I would like one that does all the "bells and whistles" stuff (image stabilisation, auto light balance, H.264 compression etc). But I also want to be able to turn off all the clever stuff and access the "raw" video. Any recommendations? Hard disk/SD recording is a must, high definition would be good.

DVD/Handbrake Divx Burning Woes

I using Mac the Ripper than Handbrake to turn DVDs into mp4 files. (I use DVD dual layer)...When I use Roxio Popcorn, I can fit several movies on a disc (4) but it takes honestly a day and a half to burn on DVD !!!! But the DVD plays perfectly in my cheap player. Trying a different route, I tried dragging the mp4s to a blank DVD disc and then clicking "Burn" -- it burns and takes only 30-40 minutes but this version will not play on my DVD player. Anybody out there have an idea what I can do to make the process more efficient? Different software or different method? I appreciate your insight. By the way, I am running Mac OX X 10.5.5.

What sort of inaudible audio signal survives compression?

I recently became an Arbitron ratings person (which I'm not allowed to tell anyone, hence my anonymity).
