Time base corrector
on Apr 28, 2008 at 1:19:00 pm

Hi there,

I'm about to embark on a project that uses a lot of source material that comes from VHS cassettes (ugh!). Anyway, I'll be digitizing the footage through my Kona LH and I'd better get my hands on a time base corrector before I even start. So...

Has anyone got any advice on buying a decent, yet inexpensive, TBC?

Thanks.

DATAVideo used to make an extremely cheap yet effective SVideo TBC.

You don't have an io or ioLA do you?

I'm afraid I don't have any of the io line, just the LH.

Thanks for the info, I'll look into it.

I would just dub the VHS tapes to Mini DV or Beta then digitize.

The LH does not have built in TBC? Surely the Kona3 does.
I guess thats one way to keep the price down.

You might look into "video clarifier" devices.
They are really low cost composite (some are s-video too)
tbc's perfect for such a thing. They usually have a 9-volt
battery for power and optional dc inputs.

The Kona 3 has no analog inputs. Therefore no TBC or proc amp features.

HI

ebay

If you have a pro deck which has connections on the back for a Drop Out Compensator aka DOC, which is usually an "off tape RF" connection, as well as advance sync, then you should look for Fortel, Hottronic, For-A, and Sony TBCs. The fortel turbo was one of the best, with these great chroma decoding circuits, and i have seen them on ebay for 500

the DOC and Advance sync are waht give you a true "Time Base Corrected" signal which is cleaner to capture or even bump to DV or BetaSP

Of course if you dont have those connections, and you are dealing with a consumer VHS deck, you might as well dub the material to DV, digitize it, and do any correction in FCP

its not the best but its better than trying to dump it straight in.

hope this helps

Howdy, in a pinch if you have a standalone DVD burner they have internal TBCs that work pretty well. Come out S-video and analog audio into the DVD player. Then if its a nice one take the component out for video and the analog out into the Kona. You will be capturing now so if you need repeatablity starting dubbing and go to lunch!

Re: Get a JVC SVHS Deck with Digipure (DNR plus TBC)
on Apr 29, 2008 at 11:42:34 pm

Hi,

As a minimum I would start with an S-Video deck with Y/C output.

They might all be discontinued but the more expensive (about $400) JVC consumer decks had built in Noise Reduction and TBC, called Digipure (I think if its called Digipure it has both DNR and TBC). We compared the playback of a JVC HR-S9911 (consumer SVHS deck - about $400) and we preferred the quality to a Panasonic AG7650 (multi thousand dollar professional deck).

If you can't find a JVC S-video deck this might do it (double check and make sure it has TBC):

JVC DH30000
http://support.jvc.com/consumer/product.jsp?modelId=MODL026758&pathId=15&pa...
# DigiPure Technology for high resolution analog recording and playback
# 1080i, 720P, 480P and 480i
# 2 Sets of AV inputs
# S-Video inputs
# 2 Sets of AV outputs
# 2 S-Video Outputs
# 1 Component Video Output (Y, Pb, Pr)
# 1 x Optical Digital Output
# 2 x I.Link Terminal (IEEE 1394), DV input only for camcorders
# Front Inputs ( AV, S-Video, i.Link)
# Frame Synchronizer for pristine analog-to-digital dubs

Its been discontinued but there are still a couple of companies that list it:

http://www.google.com/search?q=JVC%20DH30000&hl=en&sa=N&tab=fw
# Frame Synchronizer Eliminates Jitter & Noise From The Input Signal To Produce High Quality Dubs
# DigiPure Technology Helps Stabilize The Picture Of Old Tapes & Rental Cassettes
# Precision 3-D Color Circuit Provides Clear Color Separation & Sharpens Image Edges
# Precise Digital 3-D YNR/CNR Improves The S/N Ratio By Approximately 3dB
# Digital R3 Picture System & Digital 3-Dimensional Circuit With 4MB Frame Memory

http://www.electronicexpress.com/product?prod_id=2944&refer=6&cpc=6
Closeout Price: $299.50

If the playback quality is as good as our JVC HR-S9911 you will be very pleased.

Two units available on Ebay. If the S9911 is in good condition I highly recommend it:

Best Wishes,



Mitch

yeah no kiddin, its kind of a shame that D-VHS could
not have been utilized for broadcast, all it really
needed was a timecode track, it would have been
a great way to deliver TV spots in SD or HD.
