Title: Forgot to format as exFAT, don't worry.
Post by: nigel on July 26, 2013, 05:25:01 PM
Now while i do not claim to be an expert, there may be an 'official' way of correcting this. But it worked for me so i thought i'd share with you guys.

Today i tried for the first time taking RAW video, but i left my house in a hurry after installing, i forgot to change the CF card format as exFAT.

I took it in FAT32 and when i got back i had 2 files.

M26-1721.R00 and M26-1721.RAW

raw2dng.exe could not read the M26-1721.RAW file.

I decided to try using a file joiner like HJSplit to amend the 2 files together.
Get it at http://www.hjsplit.org/ (http://www.hjsplit.org/)

First i checked the time the files were created, modified and their sizes

M26-1721.RAW  Created 5.21pm, Modified 5.22pm, 4.3gb
M26-1721.R00   Created 5.22pm, Modified 5.22pm, 700mb

So from that i knew that M26-1721.RAW came before M26-1721.R00.
I then renamed the files to M26-1721.RAW->M26-1721.RAW.001 and M26-1721.R00->M26-1721.RAW.002

Then i opened up HJSplit and selected the join files button and after 10 mins it was completed.

Imported it into raw2dng.exe and it worked flawlessly.

Well i hope you guys don't make the same mistake as i did!

Cheers,

Nigel

Oh. yep. Bumps up the search results.
I didn't search the forums then because i wanted to see if it worked.

Thanks for letting me know though..

Good one, Nigel, thanks for sharing that.

Now, can anyone give us some tips on getting Canon to write H.264 files larger than 4 GB, especially as they've made all late-model cameras exFAT compatible?

For H264

50D/550D/5DII - no hope, 32 bit file sizes

600D/60D - 600D patched, 60D nobody tested

6D/650D/M/etc - Can be patched but auto split so no point.

Hi,

I tried the join files program, BUT, I only get pinkish frames!
Really distorted, pink pixels.

I read somewhere that the files need to be changed, header I believe it was called.
But I do not know what this is.

If anyone want to give it a try explaining, I am thankfull.
If not, I'll just keep trying =)

Cheers!
