Hello everyone, new to BM forums and proud owner of now several BM products. I have a problem with my set up with respect to recording legacy retro computer output to digital (upscaled of course to 1080p) for my new soon-to-be-launched YouTube channel.
Set up - I have a SCART-to-Component signal converter (tried two different ones - same result) that converts the SCART output signal of the Amstrad CPC6128 to Component video. This is then connected via BNC cables on back of Teranex Analogue to 12G converter.
When I power on the Amstrad, I get what you see in the attached video. It seems to be a FRAME SYNC kind of issue. Picture quality is solid though. Suffice to say connection to old school TVs and legacy inputs on older LCD monitors is SOLID. Side note: I tried an Amstrad CPC464 and the signal was PERFECT.
Amiga 1200 is perfect.
I tried a BBC Micro computer and I get a similar problem to the Amstrad. I also see "purple" artifacting in the image of the BBC micro.
I tried a Commodore 128 and I can see the image trying to sync up but then drops it - aka no display / signal on the Teranex.
Long story short is I am kind of stuck. My journey so far: I have an OSSC but the HyperDeck 4K and ATEM Extreme ISO don't see the output from OSSC (this is a known issue with it and digitisers). I tried the RetroTink 5X and this works with the HyperDeck 4K and ATEM Extreme ISO but not always perfectly. For example with the Amstrad CPC6128 the screen is stable frame sync wise but the screen shakes and moves (that's down to RetroTink and I am sure it can be fixed by them). Tried the Elgato 4K60+ and it does not work with the OSSC. works ok with RetroTink. However regardless of all other "solutions", I like the idea of trying to keep it simple. It either goes to ATEM or hyperDeck via HDMI (RetroTink) or via Teranex. I thought given all the marketing fluff that his PRO device could handle anything from the PAL/NTSC era - but not it seems old-school microcomputers. I accept that their internal video encoding logic may not be modern but it's simple. I would love for BM to adapt / modify their Teranex software to "understand" older micro-computer video signals. Or at least put in the options/settings menus ways to modify the frame sync or other parameters, etc. I am not expert in video signals or what causes these kinds of artifacts or why one model of Amstrad works fine with the Teranex and the other not. Or the Commodore 128 just completely fails to invoke a signal.
Is there anything I can buy that will "clean" up the signal before it goes into the Teranex? Frame syncing or other devices that "correct" any inconsistencies in the signal?
Anyone have any advice / experience in digitising retro computer outputs for recording?
Thanks all.
