Video Format for archiving
« on: October 09, 2007, 07:25:19 PM »

what format can we use for archiving the sermon.. we will be recording straight to harddrive but we want to then archive it for possible editing in later.
using dv avi is huge but if we use mpg i degrades the file...

Thanks!

We archive video with a DVD recorder.

You're right; uncompressed AVI files are huge, but there is no degradation. You could copy the AVI file to an external hard drive or possibly burn the AVI into a double-layer DVD (8.5GB) as a data file.

Another idea would be to record the video to DV, DVcam or DVCPRO videotape at the same time you record to hard drive, which would give you recording redundancy (in case the computer fails), and an edit-ready copy on tape. Some recorders give you a number of format choices in one unit.

You could render the video to a compressed format, such as MPEG2 or Windows Media, but there will be some degradation.  Arnold's point about recording straight to DVD makes sense, too; cheap, little storage space. I edit in Sony Vegas, and it accepts just about anything.

I agree, direct to DVD with a $200 stand alone recorder to archive.

Sorry to hijach the thread, but...  Greg, how easy is it to learn Sony Vegas?  I am using Womble Video Wizard to cut and trim our live-mixed Sunday service as it is fairly intuitive and accepts the .VRO files from our consumer grade Panasonic DVD recorder.

I use Vegas. Found it very intuitive. the training videos are supposed to be very good also.

+1 for Vegas.  Much easier to use than Premiere.

I use mediacoder to compress regular DVD movies onto a portable player. It has several codecs and you can select the quality too reduce the actual file size. I typically compress full length movies to around 1GB with good results when played on a standard television screen.

The only drawback is the time it takes to recode the original signal. It can be configured to recode several files sequentially so you can let that run at night.

I'm not sure if this is exactly what you were asking but it may be an option to consider.

I'm responsible only for sound but have been called in to help the video guys with a problem. My church has decided to provide DVDs of sermons straight after the service.  They have purchased a 1x10 duplicator.  

A consumer grade DVD recorder was also purchased to record the master DVD which is then rushed out to the bookstore for duplication.

However we have a lot of noise in the audio signal.  This may be a cable problem that we need to solve as the consumer unit uses unbalanced RCAs, and even despite connecting directly from unbalanced RCA outputs on our mixing desk, we get a kind of digital whining hum when listening to the outputs of the DVD recorder.  This we may solve with better cables and perhaps some balancing transformers.  The DVD recorder may also be faulty.

However even if I solve this problem, I have no idea how to match the levels so that the DVD is recorded with a decent quality audio signal.  The consumer unit has no input metering.  How can we know we are providing an optimal signal which is hot enough so people don't need to crank their TV volume controls, but will not be distorted?  We have no time to normalise the audio signal in post production since the DVD's are duplicated immediately.

Semi-pro CD-recorders are relatively easy to find and have good audio metering.  Any suggestions on semi-pro DVD recorders with input meters?

If you take a look the manual it will probably tell you what its max input level is. From there you should be able to devise a monitoring solution.

That said I would probably run to the unit with balanced audio and then go through something like a jensen PC-2XR http://www.jensen-transformers.com/datashts/pc2xr.pdf

Alternatively you can use a semi pro recordered such as the Datavideo MP-6000 http://www.datavideo.us/mp-6000.html
