How can I convert a TRUEHD stream in a .mkv file to .ac3?
Hi,
I have a .mkv file with a TRUEHD audio stream. I want to convert the audio to .ac3. Is there a program that will do this automatically? If not, I have managed to extract the audio and make a separate .ac3 file. How do I insert this into the now audioless .h64 file and rebuild the .mkv file and make sure it syncs up? thanks! BB |

The warning in MKVMerge you speak of is just some stupid error because the input can never detect the FPS of raw h.264 streams. You need to manually set the FPS in the "Format Specific Options" tab with your h.264 stream highlighted under the "Tracks, chapters and tags:" box. Otherwise it just blindly assumes the video is 25 FPS PAL.

=> You don't need to convert truehd to get 640 kbps ac3, you can just extract it from truehd. 2. You can mux the video + audio into an *.mkv file using mvktoolnix, just don't forget to manually add the framerate. It's 23.976 fps for most Blu-Ray videos.
