sharpen vhs capture

[maxwell3]

Just finished my first vhs cap using iuvcr/huffy encode w/tmpgnec dvd source creator came out great al;though without sound (capture issues) . Question is I notice a definite softening of the video vs the vhs tape .Is there some way I can correct this

Most of the time it's due low data rate. Who's codec are you using?

I have Prosumer and broadcast VHS/SVHS decks. They have a setting for transfer. Baiclly it turns off the hi freq roll off in the VCR. You may say that is looks a little grainy, but when the clip is played back it should look like the tape.

You could also use a video proc-amp in series with the vcr output to give a little boost. It all comes down to, does the input of the capture device load down and drop the hi-freq responce.

Some capture software have a sharping control. I always turn it to MAX!

If all else fails, use either xsharping or general convolution 3d filter to sharpen things up.

Im captureing from a jvc svhs-s2901u using svideo out to an MSI tv@nywhere and Im using iuvcr w/huffy then encodijg to mpeg 2 w/tmpdenc dvd source . I did notice that iuvcr has a sharpness control Ill try plating with that . You mention a video proc amp . Im not familiar with this can you recommend a source to get one or perhaps a model to lokk at . I wonder if using a digital camcorder with analog to digital passthru would give better resulsts . Have you ever tried this ? Thanks

Back when VHS came out there was a whole bunch to choose from. I have two made by VideoCraft. From time to time you will see them on E-Bay. I don't know know if they made a PAL model or NOT, but a NTSC unit can be made to work with PAL by a cable modication.

What to look for is one that does Video sharping and apeture correction sometimes called Conture. These circuits can be made by a video hobbist as well. There are many circuit designs on the web.

A pass through would be nice, but do they inhance, I don't know.

However analog is always better than digital when it comes to this, and it happens in real time. You can control it while capturing.

are those broadcast VHS/SVHS available to buy somewhere?

which company & model are them?

I really need a really good VHS Recorder...

my cheap Grundig VCR doesn't give the best picture.
most time haloing and smeared low-contrast detail :(
