Automated Cutting and Transcoding Guide Using Mencoder

[erik]

Erik,
- regarding your recent post and how the program identifies the borders of active video,
does this calculation take into account the presence (or absence) of the logo?
I ask because I was transcoding an IFC channel video which was displayed in letterbox format, and maybe 1/4 to 1/6 of the logo was actually over the video and the rest was over the black bar widescreen area. So if the logo could effectively be ignored comskip would show widescreen dimentions.

Comskip ignores the logo area in determining the active video area

The wiki states that this script can be used from within postprocessing.bat file. Any hints on how to implement this? I assume that just renaming it to postprocessing.bat is not enough?

Assuming the Quick Start paths are correct, you would just need to set:

Code:

SET guide_mode=no

Then rename the file to postprocessing.bat.

You can test this out by dropping a video file on it. The script should automatically process the file.

Hi,

I'm using stattik_transcode_0.5.5b.bat

I've probably got some settings wrong.

Although I have a file there, it comes back saying nothing to transcode.

I've got one file in c:\videoT\Small Railway Journeys_20080414_11451200.dvr-ms

I've changed
SET ptl_ext_check=.avi .mp4 .mkv .dvr-ms

I think I've set the other variables as needed.

I've done a debug run which I've attached.

Thanks
Alan

Hi Firehorse,

I haven't gone though the entire debug yet but I would suggest you make sure you have this set:

Code:

SET transcode_extension=dvr-ms

By default it's set to mpg but since you have dvr-ms files, it will be needed.

See if that helps.

I've done that. It seems better but it still doesn't appear to be detecting the files.

I 'intend' to keep everything at the top level of c:\VideoT so I've set the following. I don't know if they are correct.

SET recordings_path=c:\VideoT

SET individual_transcode_directories=""
SET recursive_transcode_directory=c:\videoT

I've attached another debug run.

Thanks

Ok, I found the issue.

First set ptl_ext_check back to the original setting. This setting checks to see if a transcode is already done. (IE: If there already was a avi, mp4, or mkv file made) so you'll want to remove dvr-ms from that list or else nothing will transcode.

Code:

SET ptl_ext_check=.avi .mp4 .mkv

The part of the script that's dropping the dvr-ms file is the part where it looks for an associated EDL file. Most users run comskip on the file which creates an EDL file (by configuring comskip.ini). If you're not using comskip, you can set

Code:

SET target_extension=dvr-ms

The rest of your settings will be fine. One issue you'll run into in this situation is once the file is done processing, the script will run again, find the dvr-ms file again, and process it again, and again, etc. The solution to this is either to delete the original file after processing or have the script move it to a directory that doesn't get scanned. Obviously, I'd make a backup of the video file until you're happy with the output.


Hope this helps.

It's getting further. Now comes up with mplayer.exe not being able to find pthreadgc2.dll ???

I thought I downloaded the right version. I'm going back to check

Thanks

Hi,

I tried downloading the latest version
MPlayer-mingw32-1.0rc2.zip
from here
http://www.mplayerhq.hu/homepage/design7/dload.html

When I click on that, everything seems ok.

I copied that to the amd-64 directory, and then copied amd-64 back over it for the processor specific version.

When I click mplayer, still the same problem.

I'm going to just try it with the standard mplayer because I can't figure out why the amd-64 version doesn't work.

There's a few builds of mplayer/mencoder that require pthreadGC2.dll

There's a few places you can get it. Here is one:

ftp://sources.redhat.com/pub/pthreads-wi...eadGC2.dll

Drop it in the mplayer dir.
