Audio and Subtitle Options



HDConvertToX can either re-encode or copy audio from your source. It can also copy subtitles without re-encoding to avoid a lossy conversion.

To Convert or Not To Convert

When video encoding was commonly done to fit an entire movie on a single 700MB CD compressing audio files to a more efficient format like MP3 and keeping only 2 channel audio were important parts of saving bits to retain video quality. With the rise of HD video, traditional AC3 (Dolby Digital) audio and other surround formats amount to an almost trivial percentage of the disc space used by a video file.

If space is still a big issue for you or surround sound isn't important this is still a valid approach. But if you want to retain the highest quality audio possible consider keeping the source audio as-is.


Select Audio & Subtitles



On the Audio & Subs Selection tab you will find a list of audio and subtitle streams available for your encode. Select the ones you want and whether you want them encoded into the video stream (permanent subtitles) or muxed into the video file as separate streams. Even if you want a default subtitle, you can set that option in the container and still be able to disable it or see a different subtitle. In most cases you should select Mux Subtitles in MP4/MKV/AVI Container.



Audio Encoding Options


1. Format & Encoder

There is an extensive list of encoders to give you many different types of audio file. Use the Copy Audio option to keep the original audio from your source file.

2. Normalize Audio

Normalizing attempts to minimize the amount of volume change in a movie. This is generally done to make it more "living room friendly." You can turn it off if you prefer.
