PAL-M to NTSC conversion?

Hello.

I have a VCR that (it seems) only gives PAL-M (it was made for the Brazilian market, and Brazil has PAL-M only) on the composite (RCA) video and RF outputs.

The VCR doesn't have S-Video, so this isn't an option to consider.

I need to use it with a video capture card on my PC, that only does NTSC.

I know there are some converters available, but I can't find anybody selling them here in my city.

Q: How would I go to make a circuit to convert PAL-M to NTSC? Is there any specific IC that can do this?

Check out these folks:

That's not the hardest part - what about 50fps to 60fps? This question comes up very often and the answer is always "It is too difficult - buy a pre-made converter."

Double check software. Download software for PAL-M countries, and you might be able to set the capture card for PAL-M.

Not for PAL-M. You are forgetting that PAL is simply a colour encoding method, which rides upon a lines/FPS structure. PAL-M uses the same picture layout as North American 525 lines/30fps video, but with PAL encoding, therefore it would be as simple as getting component from that, and recoding the component to NTSC.

Both PAL-M tapes and VCR. (they're recordings of old TV programs)

So, does this means I just need to:

DECODE ENCODE PAL-M COMPONENT TO ------------> TO COMPONENT NTSC (YCbCr?)

If so, any specific IC's that can decode/encode video? (With those, it would be less difficult)

When I lived in RJ, I had a VCR modified for around 80$US. In SaoPaulo you will find these Video shops, probably also in any other bigger town. I doubt you will find anything outside Brasil, because it is the only country with PAL-M. A lot of quality got lost by the conversion. Later I bought a Panasonic NV-W1, which can do all kind of conversions in high quality. It is a legendary part and will be quite expensive on Ebay.

In theory, yes, if you cannot get the card to process PAL-M

I will have to look for those in a few video/electronics stores in Porto Alegre (my city, Canoas, has none).

I'm going there anyway (looking for a new PC), so it won't be a problem.
