Hi folx.

The Situation:
You have a MKV-File with 23.976 FPS, 24.000 FPS or 29.970 FPS and want to convert it to PAL 25 FPS (30 FPS at a FPS of 29.970) to see the movie totaly smooth on your tv which is not supporting 24p correct. If you Speedup the Movie to 25FPS (or 30 FPS) you have the problem that the Audio-Track must be edited. There are 2 Ways:

1. Timestretch (that keeps the original Pitch but has the big disadvantage of creating Audio-Artefacts which doesn´t sounds well)
2. Speedup (The Audio-Track plays with approx. 4% more Speed. This method is used by Pal-DVDs because orig. Film-Material is ever in 23.976 FPS)

I want to go the 2nd way. Unfortunately for OSX doesnt exists a tool which can Speedup AC3 and DTS on thy fly. We will use eac3to from Windows-World.

Now i build a post-process-script the extracts the whole MKV-File (if it´s not already in 25 FPS) in his elementary streams. After that the script runs eac3to via Wine.

The script looks if the movie is in 23.976, 24.000 or 29.970 FPS and start to convert it to 25 FPS (30 FPS at a FPS of 29.970). If the File has 25 FPS the script do nothing.

For my script you need additional programs which i have bundled:

And here is my Script:

Sorry - just deleted my last post - didn't intend to threadjack.

Nice work.

Hello,

Thanks for the scripts, I have the reverse question. I get some content from the UK and they are encoded in 25 fps mkv, how do I switch it to 30 fps mkv to play in my tv here in the US.

I will play with the settings in the script and see whether I can sort it, but if you know it right off the hand, please share it.

Greatly appreciate your work.

Thanks,

Hi Folx.

Hm my old account don´t work. Created a new one.

I have a bigger update. I enhanced the Script.

The biggest news: Now you can encode with the Surcode DTS Encoder completely automatic. The script searches if the audio is dts and initiate the needed steps. Macros for the Mouse are managing the push of the needed buttons in Surcode DTS Encoder (which is completely GUI-Only .. suxx

)

You need this stuff:

- Wine (use Darwin Ports or search for a precompiled Package)
- eac3to ( http://forum.doom9.org/showthread.php?t=125966 )
- mediainfo CLI Version ( http://x7.to/hjb4w7 )
- mkvextract ( http://x7.to/tr77g2 )
- Surcode DTS Encoder DVD (look for it in the world wiiiiiiiide web (-; )
- For DTS-Encoding you need this too ( http://www.bluem.net/de/mac/cliclick/ ) .. copy this file at /opt/local/bin or if u want another path for this you must change the path in the surcode.sh too.

This 2 files you need to record again with Recorder (because you probably will have other coordinates of the buttons from Surcode Encoder (depends on the Display-Resolutionand place it inside the sabnzbd script folder too.

Ok now let´s show the updated script. U will need a 2nd script which depends on the first "big" script. Here is the big first.

Filename: As you want

OK guys. I hope i could help a little bit. The Development of this thing needs a lot of hours. Have fun with that.

Test at what Coordinates your "Encode-Button" is. Press shift+cmd+4 and move the mouse in the middel of the Encode-Button of Surcode DTS and replace ist with my 770 696 in this script. 770x696 is at a Screen-Resolution of 1920x1080.
