Is flash  memory compressed?

I just read something in an article that is either wrong or shows that I have been laboring under a falsehood.
Is flash memory COMPRESSED or NOT COMPRESSED? I was leaning towards a flash memory camcorder because it was free of the compression found with hard drive camcorders!

This comes on the heels of John C. saying that he would leave his AVCHD and get flash memory if he were to buy another camcorder. May I ask some questions?
1) *Why AVCHD?* What are its advantages? Is the advantage its newness? And does it have any downsides? Isn't it that iMovie '09 does not accept the kind of file that AVCHD sends? Or am I mixing AVCHD up with something else?
2) I see that the advantage of high definition is beauty, but it has real downsides in that it is such a memory gobbler, and for Youtube with those ten minute restrictions plus the megabyte restrictions, high definition would leave me with less time to present the actual video content.
Get an AVCHD camcorder from a leading brand like Sony, Panasonic, or Canon.
The Sony is an old mini-DV tape standard def camera. The Canon is an old MPEG2 standard def camera.
.......... Lorna says ...........................
Well, I like Sony and Canon and have a Panasonic telephone so those are all ok with me. So ok, my presentSony digital video camera recorder DCR-TRV 11 is an old mini-DV tape standard def camera and I should not buy a dinosaur technology, and that would include MPEG2.
So I will go now and research my eyeballs out looking for an AVCHD camcorder. But John C., if you are reading this, would you please tell me why you said that you would switch from AVCHD to FLASH MEMORY?
AppleMan: Is AVCHD memory that which is found inside a HARD DRIVE? Because if that is so, then I would be buyina a camcorder large enough to accommodate that memory size. <charcoal grey descending>. If I am wrong in my assumption, please let me know.
The picture quality on High Def versus standard is amazing, and if you are getting a new camera, you should go for it.
.......... Lorna says ...........................
AppleMan, I Know that the High Def picture is lovely. <Sigh> I was ready to give it up in exchange for having memory inside a little Flash Card.
I would imagine that someone told you to avoid CMOS, but CCD is rare these days in consumer cameras. I have one (the Panasonic HDC-SD5), but the Panasonic cameras in their current line all use CMOS. Personally, if I bought a new camera, I would make sure I got a camera that is 1920x1080, progressive (not interlaced), and a good optical zoom.
.......... Lorna says ...........................
Actually I read that about CMOS affecting Image Stabilization within the iMovie '09 application. I then found out what CMOS was (a type of image sensor). More reading told me that the preferred type of image sensor was CCD, and that is when I narrowed my choices to CCD and kicked out CMOS.
CCD is a plus but not necessary. When I need a steady image, I use a tripod. I have used image stabilization with good results, but it is nice to have, not must have, and you sacrifice some quality in the stabilization process.
.......... Lorna says ...........................
I cannot carry a tripod around, though. 8-( But this revives an old question that so far has not been answered: If iMovie '09 has that special image stabilization feature in it, then wouldn't it do the job anyway? So that the lack of IS in the camcorder would be an irrelevancy?
When you pick a camera, try it out in a store. Do not buy from specs only. And do not over think it.
.......... Lorna says ...........................
Appleman, if I had followed that advice up there about not over-thinking it, I would have bought the Canon FS100 from Amazon.com last night.
If your budget is only $300, I would go with a Flip MinoHD or similar. THey make great HD pictures but you give up some features like zoom.
.......... Lorna says ...........................
My budget can go over $300, but I was thinking that since I already have an expensive Sony digital video camera recorder DCR-TRV 11, I should try and be practical with this second camcorder. But I can afford higher.
The best stabilizer is a Steadicam Merlin, but they cost around $800 and there is a learning curve that many people never get through.
.......... Lorna says ...........................
I assume that a Steadicam Merlin is one of those big honking tubular mechanisms that take the shake out of the camcorder. Well, such an inconvenience is not for me. *I want a small, lightweight camcorder.* Hauling around a Steadicam Merlin or Neptune or Aphrodite would never happen with me.
And now I am going to Google around for camcorders that are ACVHD MEMORY, in Sony, Canon, or Panasonic. Probably Canon because I keep reading how Sony gives problems for uploading to the computer.
Also, I have a Canon digital camera: SD970 IS. It also has a video.

  • Unable to boot from my USB Flash Memory Device

    Hi there,
    I recently purchased a macbook pro with the lion 10.7.2 firmware.
    I am experiencing problems with my USB Flash memory as when i plug it in it comes up fine on the desktop and i can browse it. The problem is that when i open up an application such as Adobe Fireworks or Netbeans (Java programming) and try and access files from my USB flash drive, my drive does not appear on the list/menu, it only comes up with my macbook pro documents etc.
    I have asked friends with Mac's and they tell me they do not experience this problem. Please can you help me whether it is a problem with my settings or any other issues.
    Thank you.

    Nope, I dont recieve any massages at all. It just doesnt appear.
    Also usually you can drag a file into an application, for example drag an image into photoshop in order to open that image up but this does not work either.

  • How can I use my Zen Xtra like a flash memory

    Hello, I want to know how can I use my MP3 player like a flash memory.
    I have one and if I conect it with other computers I can't transfer documents and with a flash memory I conect it in all the computers with Windows XP and all of they detect the flash memory and they can transfer documents.
    With my Zen Xtra I connect it and the computer detects it but I can't transfer anything because the computer doesn't have the software.
    My question is.. Do I have to install the software in all the computers that I use ? or there are other forms to conects PC and MP3 Player? ( I want to transfer documents like text, image, etc)

    But some MP3 players do that, why this one can't be connected with all the computers ?

  • I've bought a new USB flash memory. I plugged it in the USB port then a message come out: Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.... Please help...

    I don't know what to do. I plugged that USB in both ports but the same message came out. I charged my laptop and the same thing happened again. The surprising thing is that I tried plugging the USB in my cousins laptop (Macbook Pro) and it worked!!! but not with mine. The USB flash memory made by PNY. Please help...

    There are two types of USB 2 devices - low power which consume 100 milliamperes or less from the USB bus and high power which consume up to 500 milliamperes. Your flash drive is probably a high power device and is overloading the USB bus of your computer. (Some notebooks can support only low power USB devices.)
    I know that my MBP's USB ports support high power devices but I've come across reports that not all high power devices will work on the MBA and that might be the case for your flash drive. My guess is it has a large capacity? 32GB or more?

  • Can I install Windows ON a flash drive or on flash memory?

    All over the internet I see questions from people wanting to install Windows from a USB flash drive with varying results, but my question is different.  I want to install Windows ON removable flash memory.  I would like to purchase a MacBook Air, but would like to also continue making use of Boot Camp without taking up too much of my limited hard drive space.  I've found fast 3.0 USB sticks and flash cards that would be nice, but can they be treated as a partition in order to install and run Windows?

    Ignoring the fact that Windows doesn't really support booting from removable media (you might be able to force it if you are willing to build a custom installer), I can think of another reason you wouldn'r want to consider this.  Windows is notorious for heavy usage of the swap file, and I believe I recall reading one report where someone had managed to install Windows to a flash drive, and within 30-60 minutes, the OS had written to the swap file so much that the flash memory was beginning to fail.  Remember that each time you write to flash memory, it cases a small amount of damage to the memory, and after a significant number of writed, it will fail.  Regretfully, the Woindows swap file will cause this threshhold to be reached very quickly, and then you start getting write errors...

  • Installing LabVIEW DSC 8.6 Run Time on Windows XP Embedded flash memory

    I'm trying to install LabVIEW DSC 8.6 Run Time on an embedded PC running Windows XP Embedded. This has a small local disk (c), so I would like to install DSC Run Time on a secondary flash memory drive (d). The installer tells me that I don't have enough free space on drive c, but I cannot browse to select drive d. What do I need to do to get this installed?
    Thanks,
    Josh

    The DSC module can't easily be installed to external flash memory. You'll want to move any extra data onto the flash drive to free up space on the internal memory for installing the DSC module.

  • USB flash memory: "application not found" error

    When recently trying to use a USB flash memory stick I was getting an "f:\ application not found" error. I tried all kinds of fixes from Microsoft. Turns out it was caused by Lightroom.
    Since the memory stick had photos on it, my computer's Autoplay was trying to launch Lightroom. Problem is, Lightroom is listed as "Lightroom 4.0 64" in the Autoplay menu. I have Lightroom 4.4.  As far as I can tell, there's no way I can fix the incorrect "Lightroom 4.0 64" listing.  The solution is to remove Lightroom from any Autoplay options.
    This is the second such problem I've had with Lightroom.  The previous problem was right clicking on a photo file and trying to use the "open with" menu.  It worked fine when I had Lightroom 4.3.  After updating to Lightroom 4.4, it didn't work. Another Lightroom user found a workaround, which was to rename the Lightroom 4.4 folder back to Lightroom 4.3.
    These are both lazy Adobe oversights. You have to realize all the Windows functions that will be affected with an update and make sure they are updated as well. I spent half a day solving this latest USB flash memory error. Get your updating act together.

    How fast does the macbook pro with Retina Display and Flash memory work than the macbook pro with SATA hard drive with same configuration?

    kent.229,
    given those uses — PowerPoint, Word, Safari, photo storage — you could probably keep your existing MacBook Pro, replace its internal disk with a SSD, and purchase an external drive to store your photos, at a fraction of the price of a replacement MacBook Pro. (You should also purchase an additional external drive for use as a Time Machine backup destination, if you’re not already doing so — you wouldn’t want to lose 10,000 photos due to a filesystem glitch.)

  • Exporting Music From iTunes To Flash/Memory Stick

    So I did a search and the most relevant thread I could find is this one: http://discussions.apple.com/thread.jspa?messageID=5923574&#5923574
    Basically I'm going on a road trip with a friend who has a stereo head unit with a USB port, so you can plug in flash/memory sticks/cards (I'm spacing on the true terminology here). He asked if I bring along some tunes.
    So I have a 2 gig stick that I want to load up.
    Is it as easy as that thread above says? Make sure the tunes are in mp3 format, highlight, copy then paste?
    Or is there an easier/better way to do this?
    Thanks in advanced.
    MM

    If the stereo will play AAC, you can do that.
    If it only accepts MP3, you will need to convert them.
    iTunes prefs -> Advanced - Importing.
    Set it to MP3.
    Create a new playlist and add all the songs you want to convert.
    Select all the songs.
    Go to menu Advanced -> Convert selection to MP3.
    When it's done, delete the playlist you just created.
    Create a new Smart playlist;
    Match rule;
    Date created is today
    Kind contains MPEG Audio
    This should show everything you just converted.
