Audio too fast after encoding with Aften Encoder in "The Film Machine"

[Jackie79]

Hi,

I am currently trying to encode a mkv to DVD using The film machine, the source is 23.96fps, and I want to convert to 50Hz PAL. I use both the free encoders HCEncode for video and aften for audio. However, after conversion, the audio files are both way too fast, in fact it sounds like Mickey Mouse is speaking, so I guess the sound plays at double speed.

The WAV files before the Aften conversion starts are already affected, si I guess it's not an encoder problem, but the audio is extracted wrong!

Why? How can this be fixed?

Here is the mediainfo, below what's in my logfile (TFM.lg):

I think this is because of the tempo change, don't know why. You could try to do the audio conversion with my latest tool TFM Audio Tool (see my website). This has a better implementation of the tempo and audio conversion. When you have done that you can must rename the audio like the finished audio in the TFM output directory and then use the recover option in TFM starting with the muxing of the video and audio.
