Automated Cutting and Transcoding Guide Using Mencoder

[-stattik-]

If you check the INFO file that is created by the script, you may see the following line:

Code:

VIDEO:  MPEG2  544x576  (aspect 3)  25.000 fps  10000.0 kbps (1250.0 kbyte/s)

Aspect 3 will be 16:9. Aspect 2 will be 4:3. Some files don't show that info so I have to guess by checking the resolution.

I'll try to straighten out the xvid/x264 issue.

Hi gEd,

I ran the script on some test PAL files in both xvid and x264 and they both were correctly identified as aspect 3 and so used 16:9 settings.

Would it be possible to either provide a small clip (a few seconds) or the output from the script?

[gEd]

All the recordings appear to have an aspect of 3.

It worked correctly for me. Here's the output.

Perhaps you're using different options?

[gEd]

I was using it non-interactively. I'll have to check when I get back home.

Post your copy of the script then and I'll run it with your config.

Every time I run the script as two pass my files are over compressed. I am trying to trans code 1 hour shows before commercials and it keeps reading in program lengths of 16 minutes instead of the 42 minutes they come out to be after it is done converting. Any suggestions on how to fix this problem?

[gEd]

I see when you ran 5.6br it only selected the hidef and not the Pillarbox profile. When I run 0.5.6br it says:-

Flagged as Pillarbox
Flagged as HiDef

IF %input_aspect% EQU 3 (
SET ID_VIDEO_ASPECT=1.7778
IF DEFINED comskip_aspect IF %comskip_aspect:~2% LSS 6100 SET pillarbox_pro=yes

My values:
true_aspect 12
input_aspect 3
comskip_aspect 1.2600
comskip_aspect:~2 2600

So based on my values, it "correctly" selects Pillarbox but it is this profile that results in the avi being 4:3 file instead of 16:9. Commenting out the above code to prevent Pillarbox profile results in a perfect 16:9 avi.

So I am guessing you get different values to me, possibly because your comskip file has different values to mine.

Attached is the script I ran and my comskip files for this recording.

I am still having trouble getting this to cut the commercials out. attached is the script that I am using. I was unable to capture the script output from the cmd becuase the script finished just need to put a pause in there to capture it. do you have to actually install mplayer and mencoder or can you just point to the appropriate exe files which is what I have done. Thanks for the help.

Thanks for the info gEd. I'll take a look at it.
