SYNC24FPS if you are using a Mac I am writing a document here on how to repair .RAW files... Should be the same for .MLV. Anyway, this same information can be found by searching for "Damaged Header or Damaged Footer" in the forums...
Here is a process to fix corrupt files... Admittedly, it may seem like a lot of work for someone just wanting to shoot RAW, but we both know the image quality is well worth the additional exercise, right?
STEP 1:
This first step is for spanned files only. Spanned files must be merged into one file in order to be repaired. Here is how to merge them together on a Mac.
1. Place copies of all the spanned files on the desktop.
2. Open the program "Terminal."
3. Type in "cd desktop."
4. Use this code and replace "file.name" with the name of the corrupted spanned files... cat file.name file.name file.name > file.name.ALL.MLV
This is the process to join RAW or MLV files... Here is an exact copy of the files that I merged together... cat M07-2056.RAW M07-2056.R00 M07-2056.R01 M07-2056.R03 M07-2056.R04 M07-2056.R05 M07-2056.R06 M07-2056.R07 > M07-2056-ALL.RAW
STEP 2:
1. Shoot / Open a file in HexFiend that is similar in record length. Too short and you will cut off your shot prematurely. Too long and you will create empty/black DNG files. Be sure to have the same image resolution and frame rate too. *The black frames are easy to delete.
2. Scroll to the bottom of the HexFiend window or similar program and copy the letters and numbers starting with A5 A5 A5 all the way to the end of the file...

3. Leave the window open and then open the merged / damaged file in HexFiend.
4. Scroll to the bottom of the recording and locate the A5 A5 A5... If the A5 A5 A5 information is not located in your shot you will need to simply paste the information from your clipboard to the file. If the A5 A5 A5 is in the shot, simply highlight all the letters and number from A5 A5 A5 A5 and beyond and paste the new information on top.
5. Save the file to your desktop and/or to another location.
6. Now process / transcode the new MLV / RAW file using the converter of choice.
*** Note, the information from A5 A5 A5 up to the 52 41 57 appears to eliminate issues with pink frames. The information after the 52 41 47... relates to the number of frames in the shot. ***
Here is a process to fix corrupt files... Admittedly, it may seem like a lot of work for someone just wanting to shoot RAW, but we both know the image quality is well worth the additional exercise, right?
STEP 1:
This first step is for spanned files only. Spanned files must be merged into one file in order to be repaired. Here is how to merge them together on a Mac.
1. Place copies of all the spanned files on the desktop.
2. Open the program "Terminal."
3. Type in "cd desktop."
4. Use this code and replace "file.name" with the name of the corrupted spanned files... cat file.name file.name file.name > file.name.ALL.MLV
This is the process to join RAW or MLV files... Here is an exact copy of the files that I merged together... cat M07-2056.RAW M07-2056.R00 M07-2056.R01 M07-2056.R03 M07-2056.R04 M07-2056.R05 M07-2056.R06 M07-2056.R07 > M07-2056-ALL.RAW
STEP 2:
1. Shoot / Open a file in HexFiend that is similar in record length. Too short and you will cut off your shot prematurely. Too long and you will create empty/black DNG files. Be sure to have the same image resolution and frame rate too. *The black frames are easy to delete.
2. Scroll to the bottom of the HexFiend window or similar program and copy the letters and numbers starting with A5 A5 A5 all the way to the end of the file...
