Vampire Video Capture Through Elgato HD

Hello,
  I am following Vampire development since early NatAmi days.
  I also have a small Youtube Channel where I do in deep gameplays of both new and retro videogames.
 
  I would like, one day, to contribute to the Vampire community by purchasing a standalone model (when my wallet will afford it) and creating gameplay/tutorial videos specific for Vampire.
 
  I just have one doubt: I remember reading somewhere that there is some sort of incompatibility problem between Vampire DIGITAL-VIDEO output and the Elgato HD capture cards (Which I own and would like to use for capturing Vampire audio/video signals).
  Is that true? If yes, is something that will be addressed at some point?

When I used to stream vampire I had to use a video scaler to correct out put has a standard hd signal. Something like the ossc should do it.

Same as Matthew Langtry, I use an H.D.M.I scaler between the Vampire and El Gato capture card. It normalizes the video to a single stable output as the vampire can output odd resolutions in some applications and games.

It's more of an El Gato issue than anything, it only knows how to handle a few common resolutions pretty much only what a typical game console can output.

I use an elgato hd60s card directly on my vampire 1200 and I have no worries.

Mine works fine when it's running a standard 480p, 720p...etc resolutions, anything deviating from those seems to have the issue.
 
  I still prefer using my H.D.M.I.+SCART to H.D.M.I. scaler between the vamp and the el gato, it not only allows these odd resolutions to normalize to a steady output, but also allows RGB to be captured as well.

yeah i think some form of scaler where you can get a solid 720 or 1080p output is going to be - especially what my low end devices need

i got absolutely nothing out of an Elgato GamecaptureHD
i did manage to get a spark of a screen out of an Elgato Camlink 4K
the camlink did at least tell me what it was recieving signal wise, and seemed to temprementally cope with 720p@50hz.
neither liked 960x540.
The GamecaptureHD sure as heck didn't like outputting whatever it got from the IndivisionAGA. XD

i think if i was doing anything, just stick with the old school, "point a camera at the screen" and take the output off that :D

Tank you a lot for your feedback, much appreciated.

@Andy Hearn: nope, I'm not going to use the "Record screen with camera". I simply can't stand the quality of the result (Not that I'm a pro Youtuber, it's just a matter of personal tastes)

yeah i see your point though. guess if it was something i was doing, i'd want to "do it right" too :D

  I think the vampire 1200 has had fixes done from known issues from previous vampire cards in hardware

I'm sorry to say but I think its not a Vampire problem
but a "user" error problem.
 
The P96 Amiga video settings allow the users to define various video modes with all kinds of variations.
This means you can define a VGA mode with 640x480 pixel and 60 Hz.
But you could also define this mode with 50Hz or 58.5Hz or 64Hz.
And you can not only add variance to the refreshrate - the P96 config tools also allow you to change the borders and sync sizes of the video signal.
 
In short the user can define not just one video mode of 640x480
Instead the user can create hundreds of variants of this mode.
 
Not every display device likes all of the possible variations the same way.
 
So in short whether a monitor or recording device likes and shows you mode - depends a lot on the config-definition of the mode you use.
 
 
The way P96 work does give full freedom to the user to invent video modes and creatively adjust them.
I personally think that this is also a drawbacks as you can easily create modes which a monitor not likes or which a record device will not show.
 
I think you have to see the Vampire Video here maybe like a music instructions "e.g. like a flute" which allows you to play different notes and you as user have the full freedom to define whatever melody you want.
And I personally know if I play flute then I will sound awfully - not being the fault of the music instrument ... ;-)

@Gunnar

That is understood.
However, my concern is also about the OCS/ECS/AGA native modes "Upscaled" by Vampire through the H.D.M.I output.

I believe they will work well.
