Need help batch renaming video files in a specific format - batch-file

Question

I am working on renaming files that come from digital camera video recordings.
They output files in a generic incremental filename of which I do not need any information from. My folder structure is: x:\processing\01020304\VIDEO\0001.avi.
The filename I am trying to achieve would be for this example:
01-02-20121227-07h30m00s-03-04.avi
In this example, 01-02 is the first 4 numbers of the 01020304 folder. 20121227 is the date the video was created, with 07h30m00s as the ending time of the video, which is usually reported by the "last modified time". finally the 03-04 is the second half of the folder name used previously.
I'm a complete novice to writing batch files like this, but was unable to find any other examples similar enough to get myself started, so any help would be greatly appreciated.
edit:
so far I've got:
#echo off
setlocal EnableExtensions EnableDelayedExpansion
:: Setup
set "xPath=c:\processing\01010101\VIDEO"
set "xFolder="
set "xDateCreated="
:: Parse Folder Name
for /f "tokens=3 delims=\" %%A in ("%xPath%") do set "xFolder=%%A"
:: Loop through Videos
pushd %xPath%
for /f "tokens=1,2,3,4,*" %%A in ('dir *.avi /T:W /4') do if exist "%%~fE" (
set "xDateCreated=%%~A %%~B %%~C"
echo %xFolder:~0,2%-%xFolder:~2,2%-!xDateCreated:~6,4!!xDateCreated:~0,2!!
xDateCreated:~3,2!-!xDateCreated:~11,2!h-!xDateCreated:~14,2!m-00s-%xFolder:~4,2%-%
xFolder:~6,2%%%~xE
)
popd
endlocal
pause
we're almost there, just missing the seconds, and if possible id like to change it so i do not have to supply the directory, but rather run it from the processing folder and check all 01010101, 02010101, etc directories..

Since you changed the T:C to T:W I adjusted the script to just use the Last Written Date and I added the folder recursion.
When ready replace the echo line with this:
ren "%%~fA" "%xFolder:~0,2%-%xFolder:~2,2%-!xDateWritten:~6,4!!xDateWritten:~0,2!!xDateWritten:~3,2!-!xDateWritten:~11,2!h-!xDateWritten:~14,2!m-!xDateGMT:~17,2!s-%xFolder:~4,2%-%xFolder:~6,2%%%~xA"

Well to keep the script simple I am basing the formatting strictly off the folders structure you posted. This is just a skeleton script to get you started. It works, but does not get the length of the video. The length can be calculated based on the information already retrieved, but I did not feel like doing date math right now. :)

Unfortunately, the t option and dir command do not provide the date resolution needed for seconds. To obtain the full last modified time stamp of the file you can use either the forfiles or robocopy commands.
rd /Q "%Temp%\Temp" 2>nul & mkdir "%Temp%\Temp" && robocopy . "%Temp%\Temp" *.avi /TS /FP /NS /NC /NP /NJH /NJS /NDL /L
NOTE: RoboCopy returns the time stamp of the file in GMT+0! It does not return the time stamp based upon the user's timezone settings. To determine which timezone you are, use tzutil /g.
See RoboCopy /? (Vista+ or XP Resource Kit)
forfiles /M *.avi /C "cmd /c echo #ftime"
See ForFile /? (Vista+)
Edit:
I updated the code to include the last written hour and minute into the file name. All that needs to be done is to add the rename command in the loop. To obtain the seconds for the time stamp from the files, either the robocopy or forfiles commands will have to be used.
Edit 2:
Added note about RoboCopy and the GMT+0 file time stamp and updated code to work with this limitation. Added the rd and mkdir to ensure that we have an empty folder, Added the for parse for the robocopy file timestamp, and added the xDateGMT variable. This should fully work now, if I have time later, I will clean it up a little more.

Reformatted the answer to make it cleaner. See above Update section.
