Automated Cutting and Transcoding Guide Using Mencoder

[-stattik-]

I only found one instance of abr and I replaced it.
It would be great to be able to add subtitles and logo at the same time I convert to avi. Thanks

After replacing abr with cbr did the errors reoccur in virtualdub?

What do you mean when you you mention logo? Mencoder can encode subtitles but I don't know of any logo processing.

I downloaded the latest version of mplayer, etc and am trying to use the guided mode by dropping a file onto the script. I select option 2 then "Y" (because I don't know what that is) then option 7 to create a PSP file. After I press enter, the CMD window closes and nothing happens. If I turn off guided mode and drop the file on the script, it starts to decode it in standard mode. Is there something else I need to do to be able to create PSP compliant movie files? TIA

HI h00ch,

Make sure these paths are correct:

Code:

SET ffmpeg_path=C:\Progra~1\devnz\gbpvr\ThirdP~1\FFmpeg\ffmpeg.exe
SET PortableSavePath=C:\GBPVR\Portable\

If you still have problems, attach the output here.

Those paths are OK. I'm not sure if this is want you want to see, but here's the output with debug mode on.

What version of mencoder are you using? Some of the encoding arguments have changed recently for mp4 files. I'll have to update the script.

I thought I would share my current solution using ParallelProcessing.bat.

This .bat will start comskip analysis shortly after the recording starts in GBPVR. Once the recording is completed and the comskip data has been fully generated I next use the tool "addepisode" to rename the capture file. At this point my original recording is ready for viewing with comskip data. The last step is to cut and transcode the original recording, I include a 3 hour delay in this last step.

Code:

set RPPID=%RANDOM%
echo %DATE% %TIME% %RPPID% %2 PARALLEL-START %1 >>logs/parallelprocessing.log

"C:\Program Files\UnxUtils\usr\local\wbin\sleep.exe" "2m"
comskip79_98 "--ini=C:\Program Files\devnz\gbpvr\comskip79_98_gbpvr_v0.01.ini" "--verbose=0" "--playnice" "--ts" %1
echo %DATE% %TIME% %RPPID% %2 COMSKIP-COMPLETED %1 >>logs/parallelprocessing.log

"C:\Program Files\UnxUtils\usr\local\wbin\sleep.exe" "1m"
addepisode %1 "{show}-{yearshort}{month}{day}{[-]}{episode}">tmp/addepisode_%2_%RPPID%.tmp
"C:\Program Files\UnxUtils\usr\local\wbin\sleep.exe" "30s"
for /f "tokens=*" %%i in (tmp/addepisode_%2_%RPPID%.tmp) do set new=%%i
"C:\Program Files\UnxUtils\usr\local\wbin\sleep.exe" "30s"
del /Q /F tmp/addepisode_%2_%RPPID%.tmp
echo %DATE% %TIME% %RPPID% %2 ADDEPISODE %1 to %new% >>logs/parallelprocessing.log

"C:\Program Files\UnxUtils\usr\local\wbin\sleep.exe" "3h"
echo %DATE% %TIME% %RPPID% %2 TRANSCODE-START %new% >>logs/parallelprocessing.log
stattik_transcode_0.5.1f.bat "%new%" %2

echo %DATE% %TIME% %RPPID% %2 PARALLEL-DONE %new% >>logs/parallelprocessing.log

I have a question about the HDTV profile; how does one tweak the settings to balance encoding time and PQ. The resulting PQ is fair but it looks like it could use a bit more bitrate. Any suggestions for settings?

I use parallelprocessing.bat to run comskip as well. The test version of the script posted above also allows me to set the time when transcoding will occur. In addition I can also set an age threshold that will trigger when transcoding will happen (IE: transcode all shows older than 2 days.)

To increase biterate depends on the video encoder:

For xvid:

Code:

SET fixed_quant=3

2 would yield a higher bitrate recording


For x264:

Code:

SET x264_quality=21

Any lower number would yield a higher bitrate. 18 is about as low as I would recommend though.

Are you watching this on a hi-def tv or a standard def tv? You can also skip scaling of the source file.

I'm trying to come up with a solution to make better usage of the available drive space for recording without loosing quality with re-encoding unless the original source "old".

I'm looking to have stattik_transcode executed at the end of any recording from ParallelProcessing.bat or simply a scheduled job to look for any original recordings older than a definable number of days in addition to having logic that allows the trancoding of "old" recordings only if free drive space is below a defined value.

I'm recording network HDTV and displaying on a 1080p display. What kind of impact on encoding time and resulting size does it have if I skip scaling down?
