Hi Martin, I understand you are responsible for OpalVision tech support. I am trying to combine Amiga on OpalVision graphics using the OVPlayer but I get a line of white pixels down the left side of the Amiga graphics. Is there a way I can get rid of that?

Hi Andrew, Just thought I would say hello as I see that you are "on the board' again. Happy New Year. By the way, I have a flyer (beta) which I expect to get in a week or so (they say) and would be glad to discuss any collaborations which might involve it. I am curious if you have the new OPAL card and what you think of it too! Michael

Hi Michael, Nice to hear from you. I just have the OpalMain Board and as I am not really in the video arena I problably won't be buying the VideoProcessor (although if an extra $1300 fell my way I would consider it <G>). Yes, please give me a call and we can discuss possible collaborations. I Hope to go to the next IICS meeting on Jan. 11 so perhaps I will see you there.

Hello Andrew, "Hi Martin, I understand you are responsible for OpalVision tech support. I am trying to combine Amiga on OpalVision graphics using the OVPlayer but I get a line of white pixels down the left side of the Amiga graphics. Is there a way I can get rid of that?" This is actually a quirk of the harware, basically what happens is that there is a slight delay (about 20ns) between when the OpalVision determines that it need to switch between the Opal/Amiga display and when the switch actually occurs, such delays are enevitable in hardware but to overcome this a much more expensive circuit would need to be used. In a lot of cases the impact of this can be reduced significantly by changing the Amiga background colour to black or to the same colour as the Amiga graphics themselves.

Martin, I thought it was a timing problem. I will try an play with the BG colours as you suggest. Thanks, Andrew ICAM — ActiveMedia Development / IICS "InforMedia" Newsletter Editor Gliding in from Toronto on AutoPilot…
