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...

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?

This year for Christmas, I'd like to get my parents the gift of converting all their VHS tapes to digital format.

What's the best solution that fits all three? [more inside]

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]

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?

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.

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.
I am using Mac the Ripper and Roxio Popcorn successfully to rip, compress, and burn DVDs. I have leftover DVD-R Dual Layer DVDs -- is it possible to fit to movies on a DVD? I tried a few ways and it only shows one movie. Any settings I could change? Any other software? Thanks.
I recently became an Arbitron ratings person (which I'm not allowed to tell anyone, hence my anonymity). I'm supposed to carry a portable device that they say picks up "sound energy" signals embedded by participating radio and TV stations so they know what I'm listening to, even if the audio is compressed. What the heck is "sound energy"? [more inside]

Hi there, I am doing an honours project on the effects of boat noise on dolphin communication and my supervisor had this idea of using compression to analyse this. He basically suggested that we record dolphin vocalizations in the presence and absence of boat noise, and then compress the files and determine which compresses more (dolphin sounds with the boat noise, or dolphin sounds without the boat noise). His thinking was that less complex sounds should compress less...so he thinks that boat noise will compress less than dolphin vocalizations. Thus, if dolphin vocalizations happen to compress more in the presence of boat noise than they do without the boat noise...this would sort of imply they are "losing information" so to speak. Does this make sense? [more inside]
