Automated Cutting and Transcoding Guide Using Mencoder

[-stattik-]

Does the skript update the database of gbpvr?

No it doesn't but if GBPVR can't find a mpg file it looks for the same file with an AVI extension.

transcode 0.4 released

http://gbpvr.com/pmwiki/pmwiki.php/U...toTranscodeCut

The script was cleaned a bit more and it's been tweaked to try and automatically choose the best settings for more popular transcodes.

What's New:

0.4

* Video filter can be defined. Otherwise it's determined automatically.
* Fixed quant mode added. This will transcode a show at a certain quality level. A quant of 2-4 is recommended.
* Letterboxing (4/3 to 16/9) is automatically calcuated depending on input resolution.
* Output FPS is automatically determined. This can be overridden if desired.
* Test Mode has changed. Options are either no or the time (in seconds) for the test clip.
* Cutandcopy profile added(experimental). This will take mpeg and remove sections as per EDL file actions, leaving the audio/video quality untouched. This is also usefull for converting ts files to mpg.
* IVTC (inverse telecine) profile added. If you have content (mainly HiDef) that is skipping a great deal of frames on a consistant basis and output is jittery, try running under this profile.
* Twopass profile has been redone. There are two methods for twopass transcoding: size and bitrate. The twopass_15_min_size variable sets the target size of the transcode. By default, it's 350MB/hour. The bitrate option trys to create a file with a certain bitate.
* Channel patterns removed.

Feedback is appreciated.

Hi!

Transcode version 3 worked for me using drag and drop to drop a MPG recording on the .bat file, without any other configuration than entering the required program paths.

With version 4 the batchfile exits without doing anything. What can be wrong here?

Hi DrDDT,

Well first I would verify there's no typo's in the program paths since that's the only thing that you modified. If it still doesn't work, set debug=yes and start the script from the command line. (Open a DOS prompt, drag the script in the window, add a space, and then drag the video into the window and hit enter)
Proceed through the script until it's exits out, copy the output, and post it here.

I'm getting an error with mencoder:

According to the output the -fps and -ofps are set to null which is why mencoder is erroring out. My guess is that the script isn't getting the variables from mplayer. What is your mplayer_path= set to? if possible, post the output of the debug. I should easily find the issue then.

Thanks

See the attached debug output. Thanks!

Thanks for the debug. I think I've found the problem. Here's an updated script.
The PAL test file I used had a FPS of 25.048 while yours was 25.000. If it works for you I'll upload the script to the wiki.

Thanks.

Almost there!

I'm getting the 25, but somehow I get 'fps 25':

Ok, got it. This should fix it.

Thanks for working with me on this. Tell me how it works out.
