How can I extract corrupted mp4's from my SD card?

I couldn't figure out which was the right forum to post this one to, but here goes. I was transferring AV content from my Sanyo Xacti HD2000 camcorder into iPhoto on my Mac when the operation hung and I eventually had to force quit the application. Even after that, I couldn't unmount the SD card in the Finder and so I had to yank the USB cable. I was hoping that because only a read operation was in progress that the card would be OK, but two mp4 files became corrupt (all the rest are fine). So far I've tried Data Rescue, CardRescue, Disk Doctors Photo Recovery and FileSalvage - none of them work. In fact, those programs don't even recover the known good mp4 files and it's my understanding that they just don't cater to mp4 files reliably. *.mov and *.mpg files are supposedly fine, but this camcorder creates *.mp4 files.
Does anybody out there know a recovery program that can deal with mp4 files - I also have access to a PC, so a recommendation for either platform works for me.
Regards,
Mick

Hi
Just thinking.
• Can You Playback Your (Card) movie in Your Camera at all.
• If so - out via analog out to a TV ?
• If so - try using an Analog/Digital box as Canopus ADVC-55 or 110 or 300
to get the material into Your Mac

  • How can I extract a still picture from footage in iMovie, add text to it and print it ?

    How can I extract a still picture from footage in imovie, add text to it and print it ?

    Assuming you have iMovie 11 (also known as Version 9.0.4), here is how you do it. (If you have a different version, let me know. The instructions will be different).
    First, get an app called MPEG Streamclip, which is free. (google MPEG Streamclip from Squared 5)
    Open MPEG Streamclip.
    In iMovie, select the clip you need. Then, right-click/Reveal in Finder.
    Drag this clip into MPEG Streamclip
    In MPEG Streamclip, move the playhead to the frame you want.
    In MPEG Streamclip, click FILE/EXPORT FRAME.
    Choose JPEG, TIFF, or PNG and give it a name.
    You can then use this photo in Photoshop, Pixelmator, Acorn, or the app of your choice to add text.
    Here is a demo I made the other day for how to extract the still image using MPEG Streamclip.

  • How can I export 1920x1080 Mp4 directly from FCP

    How can I export 1920x1080 Mp4 directly from FCP

    Thanks Russ.
    I wasn't thinking about the Apple Devices so much as the Master File set to Audio & Video which produces a .mov file.
    I have normally used the Master File to export my videos but will experiment in future with "Computer".
    I've taken a closer look with VideoSpec and notice that the data rate of the .mov file is about 70% of the .mp4 and the file size is correspondingly smaller.
    The export/render time of the .mov is also somewhat quicker.

    How can I copy all the info from a contact card in address book to paste into a documnent?

    The advantage goes to FCP7 if you allow that it can copy and paste filters, audio and video, transformations, and other attributes separately.
    You can do that in FCPX too, as all the things you cited are listed separately in the inspector.
    Here's a little gotcha. Let's say you've color corrected a few clips and you've applied an effect to one and want to paste it the other clips. You switch off color correction and copy the clip. You select the other clips and paste effects. What do you think happens? The effect is applied, but the color correction is applied as well, only it's switched off as it was in the first clip, so all the color correction on the other clips is lost. Fun, eh?
    I'll try to replicate your gotcha - but no, that doesn't sound like fun at all!

  • How can I extract a bent CD from an Apple Superdrive?

    A bent CD has jammed in my Apple Superdrive. How can I extract it?

    Here's a list of generally accepted approaches:

    Depending on the Mac model you have, there may be other approaches, and there is always the Final Solution of cracking the case, pulling out the superdrive, and mucking with it directly. But don't go there unless you have to and/or are feeling a bit crazy.

  • How can I extract the two channels from a stereo track?

    Hi,
    I am writing a class that is able to draw an audio signal. It seems to be working well but I have a question. If I load a mono audio file I am able to draw it on a graph by using the byte[] array and everything is ok until now. That's the code:
    void Draw(byte[] x)
                Graphics g=getGraphics();
                Graphics2D g2=(Graphics2D)g;
                g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,                     RenderingHints.VALUE_ANTIALIAS_ON);
                for(int i=0; i<x.length-6; i++)
                    g2.draw(new Line2D.Float(((i*(getWidth()-6))/x.length)+5, (getHeight()/2)-          ((x*(getWidth()-6))/x.length), (((i+1)*(getWidth()-6))/x.length)+5, (getHeight()/2)-     ((x[i+1]*(getWidth()-6))/x.length)));
    The results is correct only if I have a mono track. Obviously when I get a stereo track the array becomes very large so here the question. How can I extract the two audio channels from a stereo track?
    Thanks in advance.

    A mono audio stream is stored [sample, sample, sample, sample], so just a list of samples in an array.
    A stereo sample is interleaved in the same manner, so you get [left-sample, right-sample, left-sample, right-sample]
    So every nth sample is the 1st channel, every nth+1 is the 2nd channel...

  • How can I extract a dates column from an ascii file

    I am extracting data from an ascii file and the rest of the data is extracted using read from spreadsheet, but the date appears as just the day e.g. 22 for 22nd, how can I get the date, format in ascii is e.g 22/04/2006, can I do this by specifying something at format of read from spreadsheet ? Cheers
    Emily

    Hi,
    I found the other day that there are instructions included inside the Read From Spreadsheet vi on how to modify it slightly to read strings rather than doubles.
    If you drop the Read From Spreadsheet  vi onto the block diagram and double click on it, you will open the front panel for the vi. If you then select the block diagram (for Read From Spreadsheet) you will see an 'instructions' frame below the main 'code', and the 3rd paragraph tells you how to modify the VI to read the spreadsheet as a set of strings rather then doubles. Save the vi as a new filename when you've edited it or you will overwrite the existing vi!
    Using the newly modified vi you can read in your entire spreadsheet, extract the dates as strings, then do any conversion necessary to the other columns of the sheet to change them into the types of value you require (eg doubles).
    I hope this helps.

  • How can I import an mp4 file from my video camera into my iPad ?

    I'm totally new to this iPad world.  I would like to import a file from my video camera to edit it in iMovies.  I tried adding the file through iTunes, and it appeared to transfer the file to my iPad, but I can't find any way to open the file, not even to play it.  Any help would be appreciated.

    The time should already be shown on the status bar, but you can't add the day and/or date to it - if you would like to have them then you coul leave feedback for Apple : http://www.apple.com/feedback/ipad.html
    If you want to copy an attachment from an email then you can't do that directly from the Mail app. If the email is still on your provider's server then you should be able to read the email on your provider's site via a browser on your computer and save it from there directly on your computer. Otherwise you will need to copy the file from the Mail app to another app on your iPad via the 'open in' function. Do you have an app on your iPad that supports the type of file that you want to copy ? How you then copy the file to your computer will depend upon what the app that you copy it to supports - different apps have different ways of copying their content to/from a computer e.g. via the file sharing section at the bottom of the device's apps tab when connected to iTunes, via your wifi network, dropbox etc

  • How can i extract just documents from time machine backup?

    How can I extract just my documents from a time machine backup?   I had to re-install Lion after the update screwed things up, the Genius Bar guy told me to re-install each App, and then transfer just my data (documents) back but didn't tell me how.   I only see how you can restore the entire snapshot of what was on my MacBook that day, I don't see how to select specifics. 

    Hi,
    Install a fresh Lion OS on your Mac. After this is done, then connect your time capsule. Click on the time machine icon in the dock bar so you will enter in time machine. Select the document folder and any document or all you need. The same thing you can do with iPhoto, Emails, etc.
