Reply To: 480i Problem

The bob deinterlacing is fine on my monitor BENQ RL2755HM.
However, when I record on my game capture device (Startech USB3HDCAP) the picture jumps up and down a bit.
You notice it when there is some text and I know it is related to the bob deinterlacing method.

So that’s what bob deinterlacing does; it takes each interlaced frame and fills in the missing scanlines with blank data, so a 480i image image gets presented as 480p, but doing so creates a somewhat annoying bob effect (hence the name). What you see on your capture device is how it normally presents to people; it’s strange to me that your BenQ monitor handles it just fine.

Two things I would try:
* Passthrough for 480i sources: Your capture software can probably perform some good-quality deinterlacing (two-frame or whatever looks good to you), so sending it the original 480i, or even a line-doubled 960i, would be ideal. The downside is that your monitor may not appreciate the interlaced signal, especially over HDMI.
* Applying deinterlacing with your capture software to the 480p signal: I’m not sure if it’ll allow you to do this, but you might be able to have your capture software force deinterlacing to make the bob-deinterlaced 480p signal from the OSSC look a bit less bobby (or completely blank).

Fudoh said on AVS Forum that it’s an okay device (not bad, just okay). My concerns with it would be not being able to get proper TV resolutions out of it (it’s not clear from the product page that it actually supports normal TV resolutions for output, let alone proper 480p/720×480), and it’s also not clear if it will simply do deinterlacing without messing with the input resolution.

– GCHD from Eon gaming (for the gamecube) https://eongchd.wixsite.com/gchd-by-eon

Which of these you get will be to your preference. I understand the EON GCHD will be more stable, as it also plugs/anchors into the analogue AV port. I would be hesitant to purchase one of the zeldaxpro GCVideo plug-n-plays due to the drama related to his earlier designs.

I swear there was a plug-n-play module in development that was shaped like the EON GCHD, but also offered simultaneous analogue output, but I’m having trouble finding information about it at the moment.
