Syncing Audio With Video
All,
Does anyone know how to sync audio (recorded on a home studio system) with video recorded on say Hi8 tape? Any idea how pros do this for videos? Is there some type of marker that is put on both devices at the same time so that when they are lined up everything is in sync? I'm thinking about filming my home studio practice sessions (just in case a tune or two would produce a decent looking and sounding video) but I have no idea how I would ever connect the audio with the video.... Any help is appreciated! Thanks, Steven Dillon |

To be honest, unless you're recording equipment (for both audio and video) can lay down timecode, you could be in for problems. Timecode comes in two flavours, longitudinal timecode (LTC) (audio and video) or SMPTE timecode (video only), and its purpose its to give every video frame a unique timestamp. Almost all modern digital audio recorders lay down LTC as they record. Without the help of timecode, your audio and video sources will almost always run at *slightly* different speeds. You could then end up with lip sync problems that become progressively worse (depending on the length of time the two sources run together, and their speed difference). You could go back to the old clapper board concept to synchronise your start point, but unfortunately, this won't guarantee that slippage won't happen.

Is there some type of marker that is put on both devices at the same time so that when they are lined up everything is in sync? In prehistoric days (and still for film) they use a physical "slate" or "clap sticks" to establish a sync point for each shot. In video, however, timecode pretty much replaces the need for a physical sync point. Modern sound recording for both video and film use SMPTE timecode (or equivalent). Even equipment which is not physically connected is "jam-synced" once or twice a day to keep them aligned. (Note that for "film style" production, even when shot on video, uses a slate at the head of each shot to identify the scene/take, etc. to aid the post-production editing process.) I'm thinking about filming my home studio practice sessions (just in case a tune or two would produce a decent looking and sounding video) but I have no idea how I would ever connect the audio with the video.... Many of us do "music videos" or concert productions with several "consumer" or "pro-sumer" camcorders. At every shot change (cut, dissolve, etc.) you have an opportunity to bring the video and audio back in sync. This is essentially trivial to do with modern non-linear editing (NLE) apps (Adobe Premiere, etc.) However, shooting a long-form "scene" with a single camera has more potential of drifting out of sync. But even this can be overcome if you suck the video into a computer and edit it (with NLE) and lay the mixed audio track back into alignment. |

news:JLhEb.10507$WQ3.530@lakeread05... Thanks to all who have responded! This is excellent information!! Am I going to need a really beefed up computer (4 processors and 1G of memory) to be able to run this type of software? How "difficult" is it to lay the mixed audio track back into alignment with the video once both are inside the computer? Will Adobe Premiere allow me to do that? Should I consider any other software packages for accomplishing this? One final question, has anyone tried taking what the software produces and writing it to say a DVD? That would be pretty cool! Thanksgiving day, after installing my cakewalk upgrade, I wanted to try the video dubbing at least once. I downloaded a silent film clip from library of congress, sequenced midi audio over it, converted it to mpeg with some freeware I found on the internet and burned it to a video CD using Nero Express that came with my CDRW. Whole project took a half day. Worked fine on my old Pentium 500 and looked surprisingly good on the television. If you're not mixing for HDTV, the quality bar is set pretty low. If I'd wanted to edit the video, I'd need another program.-- or drag the old Mac out of the garage, I think. dtk |

No. I have produced 60 minute videos (including an instructional tape on choral conducting that is selling on most continents) on a 300 MHz Pentium 2 with 256Mb of RAM. and that was with old Premiere 5.1 How "difficult" is it to lay the mixed audio track back into alignment with the video once both are inside the computer? Will Adobe Premiere allow me to do that? Should I consider any other software packages for accomplishing this? It is quite simple with most NLE applications. Just grab the sound track and move it forward/back until the sound syncs with the picture. Takes longer to explain than to do it. One final question, has anyone tried taking what the software produces and writing it to say a DVD? People do it all the time. Note that video editing questions really belong on the newsgroup news:rec.video.desktop That would be pretty cool! That might depend on the content! :-) |

I was over at the Moviola company a few months back, and saw a storage room with about 150 old Moviola film-editing devices in them. I asked about them, and one of the employees laughed and said, "hey, if you wanna drag one away, you can take your pick for fifty bucks." You can't GIVE that stuff away any more. Some film stuff, yeah -- but not flatbed editors. They need a ton of maintenance, and the parts are just too hard to get. Steenbeck is even worse, because I believe those were made in Germany. Those have been gone for more than 10 years. --MFW |

But I gotta say, it ain't no Steenbeck... the image quality is pretty dreadful and it's definitely much more rough on film. You can't GIVE that stuff away any more.

In part because there are spare parts machines available for cheap all over. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Never saw a Steenbeck where I worked in Florida and LA. But my point is the same: virtually no one uses this stuff. There are some things for which there is no nostalgia and little or no value. I think one thing that qualifies is obsolete computers; another is old analog composite video gear (like 1" VTRs). And another is old film editing gear. They're footnotes in history now. Some things hold on to a value, though. Film splicers are plentiful, but still cost $100 or more. But flatbed editors? Uh-uh. Ten bucks is pretty much what they're worth in 2003. --MFW |

I still get two or three guys a year coming in and doing mix on magfilm, which is basically why I got the thing. I see films now and then, especially indy releases, which have "EDITED ON STEENBECK" in the credits, or "EDITED WITHOUT THE USE OF DIGITAL TECHNOLOGY." It's definitely a Luddite thing, but it's not totally gone. On the other hand, linear video editing is totally gone. Good riddance too. Some things hold on to a value, though. Film splicers are plentiful, but still cost $100 or more. But flatbed editors? Uh-uh. Ten bucks is pretty much what they're worth in 2003. Yup. I figure it it costs me ten bucks, I can get it running with ten or twenty hours and a few bearings, that one or two rentals a year will more than pay for the space it takes up. Melissa, who had to carry it into the house, may disagree. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
