we set audio bitrate to 64kb/s

"ffmpeg": {
        "vcodec": "libx264",
        "f": "mp4",
        "acodec": "libfaac",
        "ab": "64k",
        "ar": "48k",
        "threads": 3,
        "vpre": [
          "slow",
          "baseline"
        ],
        "level": 30,
        "r": 12.5,
        "b": "96k",
        "maxrate": "96k",
        "bufsize": "96k"

but if i run mediainfo on the output is just has 48kbit/s

anything else wrong in the settings?

Hello,

Are you sure you didn’t look at a file from a different step?

I’ve looked at a sample result file (http://tmp.transloadit.com.s3.amazonaws.com/REDACTED from “mp4_416px_160k_b30”, which matches the instructions in this support ticket) and it reports an audio bitrate of 64168.

Hey Ivo,

have you investigated on this yet?

Kind regards,
Tim
