Even if you encoded it at 320 Kbps, all you'd achieve is lower sound quality, Media players are capable of down-mixing 5.1 AAC to stereo. If the original audio was AAC 5.1 212 Kbps, I would simply copy that over, I would not re-encode it to stereo. An increase of 73 MB or 0.07 GB, which is roughly the difference in size between your two files.Īs to how you encode the audio, it depends on the source.

In your example, a 94 minute 212 Kbps AAC = 143 MB file size, encoded at 320 Kbps the file size would become 216 MB. If you look carefully at the Media Info details for each file, it will show you the actual file size of each element (video track, audio track(s), subtitles etc.) along with its actual bit rate. Original file prior to converting the audio:įormat/Info : Advanced Audio Codec Low Complexity with Spectral Band ReplicationįILE AFTER CONVERTING THE AUDIO (File is Now Larger than prior to converting the 5.1 audio)įormat/Info : Advanced Audio Codec Low Complexity Would I change the bitrate in XMedia lower than 320 in this case? The rate control mode is set to average bit rate (that's the only option) When I look at the original file in media info, I see Sampling rate : 48.0 kHz Bit rate : 212 kb/s. Generally, the AAC / 320 kbps works great, however there are times when the resulting file turns out larger than the original file that has 5.1 audio.įor example my video went from being 1.26 gb to 1.34 gb. I use this to convert my files (copy the video, only change the audio to accommodate my soundbar). The process takes on average 90 seconds per 1 GB of file size, it's very quick. Press the encode button at the top and XMedia will copy over the video track (untouched), convert the audio track (and copy over your DTS if set up), copy over any subtitles and create a new MKV file. Click the Tag tab and give the video a title, then click the Queue tab and click the large blue cross at the top to add your task to the list. If there are subtitles, go to the Subtitle tab and add those.

You can also copy over the original DTS track, if you want, so you've got your basic stereo AAC track now, without losing the 5.1 DTS track, if you upgrade your setup in the future. Click the blue arrow to move your track to the right-hand window, and check its codec and quality settings match what you want.
In the Audio tab, select your DTS track, ensure Mode is set to Convert, Codec is AAC, Channels is set to Stereo, and Bitrate is set to 320kbps.
You often need to clear the track, then add it back in to ensure it's in copy mode. In the Video tab, change the Mode from Convert to Copy, check the output window shows your video track with Copy under the Modus heading. In XMedia Recode set your output format to Profile, Custom and Format, Matroska, file extension will be MKV.
