Help to write a batch file to convert recorded TV to DVR-MS

[aanda6]

As Windows 7 build 7048 and above now include a built in convertor to convert .wtv to .dvr-ms I want to run a batch file that scans my recorded tv folder and automatically runs this file then deletes the original so I can then use life extender to remove commercials.

My questions are:
Is this scenario possible?
is it too difficult to bother?
Can anyone offer advice on how to do this?

Try this



Haven't tested it myself because I don't have WTV Converter on my machine, but it should work (if not it'll create a log file in the directory it's installed in).

Just start it, it'll start minimised in the tray - double click to open, select the recorded tv folder and do a test. It should wait for a recording to finish and then attempt to convert.

I wouldn't use the delete function on anything important just yet.

does this work on VMC? Looks just like what I need!

No it won't. It is just a small file watcher application that triggers the WTVCovnverter.exe file that's included in the later builds of Win7.

If you don't have that exe, it won't do anything.

It is quite possible and easy if you have a command line conversion utility. I have seen some reference to todvrms on this website. So, I will use that utility in this example.

Here is what you do.

1. Copy and paste the following script to file C:\scripts\Convert.txt .

# CONVERSION SCRIPT
# Change directory to "recorded tv folder" (ENTER THE CORRECT FOLDER PATH BELOW.)
ccd "recorded tv folder"
# Collect a list of recorded tv files
var str filelist ; lf -rn "*.wtv" > $filelist
# Convert one file at a time
while ($filelist <> "")
do
    var str file ; lex "1" $filelist > $file
    var str converted_file ; stex -c -p "]^.wtv^l" $file > $converted_file
    set $converted_file = $converted_file + ".dvr-ms"
    # The name of the output file is now in $converted_file.
    # It is the same name as input file, except .wtv is replaced wtih .dvr-ms.
    # Convert file
    system "todvrms.exe" ("\""+$file+"\"") ("\""+$converted_file+"\"")
    # Delete original file
    system del ("\""+$file+"\"")
done

2. (If you don't already have biterscripting) Install biterscripting free. Follow instructions at http://www.biterscripting.com/install.html .

3. Start biterscripting and enter the following command.

script "/Scripts/Convert.txt"

4. That would do it.

It would be nice if MS/Someone could import that inbuilt wtv converter to vista

Thanks for that script, RandiR.

I was able to use it to convert my 50+ WTV files because I want to go back to non- TV Pack (stopped using QAM).

Suggestions to others:

1) ccd "recorded tv folder"

If your recorded tv folder is on another hard drive, use this syntax:
ccd "f:/recorded tv"

the ccd function requires a "/" instead of the usual "\".

Also be sure the todvrms.exe is in your recorded tv folder.

2) I would suggest removing the line that deletes the original .WTV file. todvrms is not a 'solid' program and it will fail often on a conversion and then you'll have lost the original WTV file. You're better off manually deleting the .WTV files.

or if you create a while statement that will only delete the WTV file if the file size of the dvr-ms is greater than 1MB, that would work. If the conversion fails, the dvr-ms file has always been under 1 MB for me.

3) To add meta data and make the conversion more stable, change the todvrms syntax line:

system "todvrms.exe" ("\""+$file+"\"") ("\""+$converted_file+"\"") "-m -v"

jrwalte:

You are welcome. Thanks for the suggestions. All are excellent.

If the conversion fails, the dvr-ms file has always been under 1 MB for me.

One can use the af command to check the size of the converted file. The delete portion of the script can be changed as follows. Perhaps, instead of a fixed 1MB number, a number based on the size of the original file can be used ?

# Delete original file, but only if the converted file has at least 1MB bytes.
# Below 1 MB would indicate that the conversion failed.
af $converted_file
if ($fsize < 1000000)
    echo "Conversion failed for file " $file
else
    system del ("\""+$file+"\"")
endif

Please do post your better script - I think you have made several other changes. I think that a lot of readers can benefit.

Just a FYI. The latest videoredo beta apparent allows you to quickstream fix WTV to dvrms. I havent used it yet, so cant comment on its effectiveness ...

Re- WTV Conversion Conclusions:
After a few days of searching, fiddling and contemplation - I have tried everything, dvrmstb, mce buddy, videoredo beta... sure it can 'sorta work' ....but all CLUNKY and or cumbersome with oft dubious results. I hate that. I hate scripts even more

I have found this the most easy WTV>DVRMS conversion option from within an XP or vista pc >>> Im sure there might be a few who find this useful
1. Run a virtual W7 from your xp/vista whetaver desktop. (Im using MS virtual PC, VMware is nice but too bloated for such a simple use IMO)
2. Make sure the location where WTVs are stored are networked so you can access them from your virtual rig
3. Use W7s inbuilt dvrms converter(accesible from R click menu) >> Thats it!!

Now I have all those accumulating WTVs ready to accumulate as DVRMS until I can be arsed trimming and encoding them

Works as fast as your CPU/Allocated RAM to the virtual rig allows. Ive got 1.5GB to my virtual W7 and converting took same time as it did in a native win7 install environment. Good ole virtualistion eh I'll be happy to abandon this method once video redo etc are smooth an steady with WTVs

Excuse my ignorance but I have a growing list of .wtv files from W7 Media Center and I cannot seem to find the built-in dvrms converter to be able to convert them in VideoReDo. When I right-click on the wtv file there is no option to convert to dvr-ms.

Can anyone help?

[dgaust]

Right click on the file and there should be the option "Convert to DVR-MS". Apparently it will only appear if the wtv files are associated to open in Windows Media Centre.
