Is 5.1 sound in old movies worth keeping it?
Hi all!
I am encoding the dvd "Amadeus". This movie was in theathers in 1984. The dvd contains a ac3 audio stream with 5.1 sound and also a 2.0 stereo stream. I wonder how they made this stream. I dont think there were dolby digital theathers at this time so the movie must have been shot in stereo. Or did they recorded several raw channels and are able to produce real 5.1 sound? To make a long story short: Is it worth to rip the 5.1 sound of old movies or is synthetically produced and not better than the usuall stereo 2.0 stream. I dont mean what would be the best source for a mp3 stream altough this I would like to know too. I really want to know I its worth keeping the six channels.

If you look at the IMDB listing for Amadeus, it says the following about the audio:
Sound Mix: 70 mm 6-Track (70 mm prints) / Dolby This should help you make up your mind. |

To answer the general question, I think it's a question of taste. I personally always revert to the original sound. I might think different with a home cinema setup, who knows? Except for mono tracks, in which case I am a staunch supporter of keeping them mono.

I agree with niamh about this being about personal preferences. If you want and can enjoy a 5.1 soundtrack, keep it. Else convert it to MP3/OGG/AAC/Whatever. Simple. I also keep mono as such since converting it to stereo will output the same stream via 2 channels which does nothing to your listening experience. The movie in point 'Amadeus', was shot in 5.1 Dolby digital surround sound.

Although imdb says 5.1 I don't know if they refer to the DVD or the original movie like it was in theathers.

P.S: Shall I tell you simplest thing to end your confusion? Do both and see which sounds best to your ears. You cannot decide which is best for -you- just by listening to others. Last edited by unskinnyboy; 10th April 2005 at 00:44. |

Here is the Amazon listing for the R1 DVD and according to it:
Available Audio Tracks: English (Dolby Digital 5.1), French (Dolby Digital 2.0 Surround) Now why didn't I think of looking in Amazon before? :/ AND, the real way to find out if you are still skeptical is to actually play it on a surround/home theater system. |

IMDB lists the movie as 5.1 --> means the actual movie was shot in 5.1 Amazon lists the DVD as 5.1 --> means the DVD was authored with 5.1 I don't know how to explain this any more, any better. |

Sorry for my bad english.
Many old movies can keep the original tracks with the music/effects and dialogs separated (necessary for translation to other languages) then now is possible to make a 5.1 with a variable quality. If the original tracks are stereo and music and effects are separated, well remastered can obtain a good 5.1. I suggest, if you don't want to spend MB in ac3, to use the stream 5.1 with a downmix Dolby Surround Prologic to a stereo mp3. Many sound systems (actual receivers, ...) can decode this mp3 and return any kind of surround to your movies. |

so, these are the facts:
1) Many movies use the oringinal elements for 5.1 remixes 2) Some of the 5.1 remixes use the oringinal 4channel master from the dolby surround track, so it's 3/1 played over 3/2/1 with monoral surrounds. It's a diescret dolby surround tracks basically. 3) Other remixes, like the terminator, use very few original elements but have execlent remixes. My advice is, that if your going to use a surround set, use the 5.1, if a 2channel, use the dolby surround track format layouts: 70mm 5/1 70mm Dolby 3/1/2 70mm Dolby SS 3/2/2 35mm Mag 4track 3/1 35mm Mono 1/0 35mm Stereo 2/0 35mm Dolby NR 2/0 > Noise Reduction > 2/0 or 1/0 > Noise Reduction > 1/0 35mm Dolby Stereo 2/0 > Decoded > 3/1 35mm Dolby SR 2/0 > Noise Reduction > Decoded > 3/1 35mm Dolby Digital 3/2/1 35mm dts 3/2/1 or 2/0 > decoded > 3/1/ 35mm SDDS 3/2/1 or 5/2/1 35mm Dolby Digital EX 3/2/1 > decoded > 3/3/1 35mm dts es 3/2/1 > decoded > 3/3/1 sorry for the spelling, don't have a spellchecker. |
