It's hard to find a tool that muxes h.264 and AC-3 streams to an MP4 container properly. Most all of them force you to use AAC, or some other audio format. Re-encoding the video would have lost quality and I wanted to keep the Dolby Digital 5.1 surround sound. Normally I wouldn't go near a beta program but I was out of options and when I read that the Yamb 2.1.0.0 beta supports AC3 in MP4 and Matroska input as well, I figured yeah right, so it says, but let me give it a try, I got nothing to lose. Yamb was easy to use, just click to add your video and audio streams (even chapters and subtitles if you want), select the output directory, click next, and it in a relatively short period of time, it muxed to an MP4 without re-encoding. I winced as I started to playback the resulting MP4 expecting like all the other programs I tried, stalled, unseekable, or warped looking video or missing or barely audiblle audio. To my surprise, it produced a flawless MP4 identical in quality to the original MKV. I also joined and split a couple of MP4's and extracted streams from an MKV just as a test and the results were also flawless. This new version of Yamb is superb. My compliments to kurtnoise on a job well done. |
