Amiga RGB to YUV and capture
« on: February 22, 2009, 08:34:57 PM »
Hello community,

I have the following problem:

I want to capture all intros and slideshows of my Amiga-group in highest quality to video. Therefore I bought a SCART-RGB to YUV adapter. For recording I have a AVID-MOJO-BOX with YUV inputs. But the signal looks noisy, is jittering and also the colors were slightly wrong. If I connect the adapter to other recording devices, which also can handle YUV, the picture scrolls through (missing H-SYNC???) or is flickering like a stroboscope. The strange thing is if I connect it to a broadcast tv monitor the YUV picture looks very good and stable. Why its not possible to capture Amigas output in this quality too?

Thanks for your hints, thomas aka d!RT!E/ moodsplateau.net

It seems no one has an idea how to solve this :( I tried also the capture box of avid liquid (ex pinnacle) but this wont work too. Its a pity...

Its a component converter from SCART RGB to YUV.
I fear its not the problem of converting (the video is shown correct on a pal monitor with yuv input) its because Amigas output is not really PAL conform... f.e. in some cases the resolution is 320x256 instead of 720x576. The video is non-interlaced instead of interlaced. Thats why the recording devices go crazy. Probably I need a good time base corrector to record the output... or is there a possibility to use a genlock?

Thanks, d!RT!E

Heya, thank you Skippy, bloodline and Iggy_Drougge. I tested recording the intros using winuae and it worked in low resolution. It looks better than via cvbs and if the other ways (pc-grafic-card-capture, standalone dvd-recorder) will not work I´ll do it that way. Now I have to find the hardware to test the other two possibilities :D

Thank you, d!RT!E
