![]() ![]() Yeah, the order of most options doesn’t really matter (unless they are related). Lets be more explicit about our preferences: We’ve just set the encoder of the first audio track ( #0) of output.mp4 to libmp3lame. But, what if we want to transcode the dubbed track only and keep the others intact? They do refer to the streams, but are options of the file, not the streams. In other words, you have to set the options in-between different inputs and outputs, and repeat the options where necessary.Īpplies to the output file output.mp4. ![]() options apply to the next input/output only (except global options) and are reset between files.You can have multiple outputs in a single command. anything found on the command line that is not an option is considered an output filename.They should all be specified before specifying outputs using the -i option. Also, notice that I’ve extracted the codec settings in a separate line (this might not work if there is some stream meta-data that override this order). In order to make the dubbed track the default one, I’ve placed it prior to the original one. You can even have both of the audio tracks if you want: Create a new file with the video taken from the high quality video and the audio from dubbed one.Extract the audio from the poor quality video using the above procedure and play it side-by-side with the high-quality video.And you have to keep the poor quality video even though you don’t need it. Play them side-by-side (use Open Multiple Files in VLC).If the original and dubbed videos are of the same length (not belonging to different television systems, like PAL and NTSC, which usually have like 5 minutes difference in full-length movies), and happen to be perfectly synchronized, you have three options: However, better looking videos of the original language are everywhere. But alas, the video quality is awful, and you can’t find a better looking dubbed video. Lets say you have a video dubbed in your native language. That’s why I usually nudge the mp3 bit-rate up a little (but that’s totally my thing and I have no evidence whatsoever about its usefulness). ![]()
