Automated Cutting and Transcoding Guide Using Mencoder

[5%NationofCasiotone]

Is there a way to have comskip not cut the credits at the end of a show? With some shows (Seinfeld) there is a content while the credits are playing and I don't want comskip to skip that. How can I fix this?

stattik,

First of all....THANK YOU FOR YOUR HELP!!

Wheeee!! Between you, erik, sub and zalkwaik (sp?) my GB-PVR is working in its basic functions I want it to do.
Record straight to MPG (thanks for the patch sub! and zalkwaik's input, correct muxer guidance from stattik, et al)
comskip is working (thanks erik)
and a few other tid bits.

So I can now watch the shows from GB-PVR and it automatically skips over the commercials! (grin, feel like a kid in a candy store!)

My next challenge has been creating a commercial free mpg file for file storage and/or DVD burning for later use on other software players or set-top DVD players.

AFAIK I have the following:
NTSC and ATSC (focus is on ATSC) signaling from my FusionHDTV 5 USB Gold
AC3 audio that gets resolved to 2 channel or 5.1 channel dependent upon the show being broadcast.

I understand some of the option in the stattik_transcode.bat file, but not most of them.

Is there a wiki or manual that outlines each option and the capabilities of each option in your batch file?

Right now, I want to have a straight copy of the mpg files without commercials. No compressing or anything. I would like to look at that later, but right now I just want to have my current mpg file with the comskip files turned into a mpg file with no commercials and smooth play.

At the moment, the original file plays fine. After processing using the mpeg profile, I get a smaller file (no commmercials), but it is stuttering and the audio is sometimes out of sync.

Help?

That depends.

First find out why comskip decides the credits are not part of the show.
No logo and a blackframe before the credits?
No logo and a AR change?
Then decide what decision method to change such that the credits are not deleted. This can be either difficult or simple.

That sounds easy enough, I'll give that a try. Just out of curiosity though, I have a pvr150 and it records into mpeg2, so does postprocessing.bat even run since I'm not processing anything after the show is recorded?

Or should I try renaming to a different batch file? Thanks

Just rename the script postprocessing.bat after setting it up. It will work fine.

I'm working on the target-size script that unixdude wrote. I hope to finish it soon.

Postprocessing.bat will run after every show is recorded. Postconversion.bat will run after any processing is don'e be GBPVR as configured in the processing tab in the cofig app.

Postprocessing.bat should work for you. Run the script in test mode if you want to verify quick.

Is the original file an atsc stream?

Hi guys - I've found this forum a great help so thought I might contribute something back.

Like a few others here, I also had a lot of problems with this script producing jerky clips which I thought might be PAL related.

Stattik replied with this:

Steen I believe I've found a fix to the avsynch issues.

Replace the tandard config line with this:

start /low /wait %mencoder_path% %name% -edl "%~dpn1.edl" -ovc xvid -xvidencopts bitrate=900:me_quality=6:chroma_me:noqpel:chroma_opt:vhq=4:bvhq=1:trellis:hq_ac:gmc:quant_type=mpeg:max_key_interval=240%turbo% -oac mp3lame -lameopts mode=2:cbr:br=128 -vf filmdint,softskip,scale=512:384,hqdn3d=3:2:3:3 -ofps 24000/1001 %test% -mc 0 -o "%~dpn1.avi"

This fixed the synch isues for me when testing your file. If it works for you I'll release an update to the script.

I tried this but the "-mc 0" didn't help me.

What I did try though was replacing "filmdint" with "pullup" and this at least produced a smooth clip BUT the deinterlacing wasn't that great. It was quite noticable with fast motion clips. I kept digging around and have now got something that works very well for me.

Replace "filmdint" with "pullup,pp=md" and I'm a happy chap!

I hope it helps someone else out there having similar problems.

Does anyone know the best way to setup dirmon2 with this script?

I am completely missing something, but it just doesn't seem to work for me.

Any screenshots?

Thanks!

stattik,

Yes, the original file was from an ATSC broadcast.

stattik,

Any ideas or assistance with my question with mencoder and ATSC broadcasts with AC3 audio and options/parameters to cut remux to mpg?

Thanks!
Greg
