Need Post Processing help

[Withbothfeet]

What I am trying to do is have recorded live TV shows without commercials, start to finish, with an accurate timeline, renamed, etc...
I figure padding the recording by 1 min at the start and finish while recording, then using comskip, comclean, retime and rename would do the trick. But...

The doc's for retime show an example of:
move “%~dpn1.mpg” “%~dpn1_faulty.mpg”
retime “%~dpn1_faulty.mpg” “%~dpn1.mpg”
comskip %1
rectracker %1 > rectracker.log

Wouldn't this "retime" the video prior to removing commercials? That is fine as long as I can run it again after removing the commercials to again correct the timeline.

What I "think" will work is:
comskip %1
call comclean %1
move “%~dpn1.mpg” “%~dpn1_faulty.mpg”
retime “%~dpn1_faulty.mpg” “%~dpn1.mpg”
RenameRecording.exe -t %1 > rename.log

OR even

move “%~dpn1.mpg” “%~dpn1_faulty.mpg”
retime “%~dpn1_faulty.mpg” “%~dpn1.mpg”
comskip %1
call comclean %1
move “%~dpn1.mpg” “%~dpn1_faulty.mpg”
retime “%~dpn1_faulty.mpg” “%~dpn1.mpg”
RenameRecording.exe -t %1 > rename.log

The example's "%~dpn1.mpg" part confuses me, as the video files do not have "dpn1" in the file name. So I am not sure what that will do.

Any of you knowledgeable/guru's have an example for me to cut and paste?
Or direct me to a more favorable way to accomplish my desired results?
Or even direct me to a thread where this has been covered?

I am a GBPVR noob. Yes I did some searches but didn't really find what I was looking for.

Thanks in advance!

PS - I'm an infrastructure guy, not a programmer... be gentle with me.

I would start by running comskip during the recording in Parallelprocessing.bat
Then run comclean to remove the commercials. Next, retime it if necessary, then rename it.
Your parallelprocessing.bat will look like this:

Code:

comskip %1
CALL comclean %1
MOVE “%~dpn1.mpg” “%~dpn1_faulty.mpg”
RETIME “%~dpn1_faulty.mpg” “%~dpn1.mpg”
RENAMERECORDING.exe -t %1 > rename.log

This lets comskip finish almost immediately as the recording is finished, then comclean will remove the ads. You must have comclean outputting the file with the original gbpvr name, or the MOVE and RETIME won't find the file.
The %~dpn1 is the default original name of the show.
If comclean is renaming it, nothing will work, so the flow is like this:

Code:

comskip identifies commercials.
comclean cuts the commercials, renaming the uncut file to _original, and renaming the cut file to %~dpn1 (the original name).
You rename using the MOVE command.
retime does it's thing on the file, producing a retimed file, with the original name.
renamerecording gives it the actual show name.

Thanks reboot!
I'll give that a try.

Many Batch files with have a %1 or %2 etc

“%~dpn1.mpg” simply (or difficultly) breaks up the Files spec passed into a batch file from a %1, so that it can be modifiyed. (eyes glossed over yet)

d=Drive
p=Path
n=Filename without the extension

Let's say the when a Batch runs, the first parameter receieved in the %1 was:

"c:\tv\Recorded\television_show.mpg"

Well, if I wanted to rename just the extension from .mpg to .avi for example I could use: “%~dpn1.avi” because %~dpn1 is really c:\tv\Recorded\television_show

Thanks for that explanation and link zehd. That cleared things up.

Reboot (or anyone else), I manually ran the parallelprocessing.bat file on a recording to test it out, but got a file name error when it gets to the MOVE “%~dpn1.mpg” “%~dpn1_faulty.mpg” portion of the process.

I assume thats where it fails, because it happens right after comclean.
Here it is:

The "gbpvr\⌠C:\Documents.mpg" part is what bothers me. That doesn't exist, nor is it the name of the file being processed.

Is comclean doing something that I need to change, adjust or tweak?

Any ideas?

[K.S.]

seems like it's messing up with your "Documents and Settings" folder (that would be your current folder in the dos-box?). how did your manually run it? from a dos box? try to drag&drop your testfile on your batch file, that should do fine

[reboot]

The "%~dpn1.mpg" is the most recent recording done in gbpvr, thus your manual run fails, because you're running it on a file that doesn't exist according to the database.
Do a trial recording to test properly.
You can log everything by putting

Code:

> namehere.log

after each step.
eg. MOVE “%~dpn1.mpg” “%~dpn1_faulty.mpg” > move.log
Alternatively, you can change that line to read

Code:

RENAME “%~dpn1.mpg” “%~dpn1_faulty.mpg” /y

and it should also work.

In your failed example, it's looking for a recording named "DOCUMENTS.MPG" in your root C:/ folder.

[Withbothfeet]

Yeah K.S., I ran it from the "C:\Program Files\devnz\gbpvr" directory (in a DOS prompt).

Command syntax:
parallelprocessing.bat "C:\Documents and Settings\Username\My Documents\TV Shows\South Park\South Park_20070107_01000130.mpg"

And you are correct reboot... it wasn't the last thing I recorded. It was a randomly picked file for testing.

Any opinions between comskip and Show Analyzer? Is one better than the other?
I noticed that you (reboot) post to the SA forums. Is that your preference?
I am not having good luck (results) with comskip. Especially when trying to pre/post pad the recordings to make sure I get the show in it's entirety.
Partially because I just figured out it needs to be tuned in. :headslap:

Ok... time for test drive v7.3 build 233 SP9

parallelprocessing.bat v2.0:
comskip %1 > comskip.log
CALL comclean %1 > comclean.log
MOVE “%~dpn1.mpg” “%~dpn1_faulty.mpg” > move.log
RETIME “%~dpn1_faulty.mpg” “%~dpn1.mpg” > retime.log
RENAMERECORDING.exe -t %1 > rename.log

I prefer comskip, now that it's been developed and sooooo much easier to tune. Also runs seamlessly with gbpvr in parallel.
I use SA manually, on other stuff, but rarely.

You call THIS easy? :eek:
