How to Capture TGM PCB Video

Thread in 'Hardware' started by Soulvirtue, 16 Mar 2015.

  1. I want to be able to record and capture videos. I believe a good way to improve would be to identify mistakes after matches.

    How do I do so?
  2. If you're only doing it for self improvement, just use whatever camera you have available.
    Though I'm also interested in a solution similar to the amazing capture cards @Muf displayed at our event this weekend, but those cards were crazy expensive. Maybe there are cheaper, more consumer friendly variations?

    Yes you can try the PEXHDCAP ! Very good for TGM, TAP & TGM3

  5. Off-topic: That YouTube video with you performing was amazing.

    You're really good.
  6. Heya cheers. It's okay I guess, terrible time for a 20G Gm though. I made that vid over 2 years ago after a 3 year break, I recently started playing it again on and off the end of last year. Looking back at it now I made some pretty bizzare placements :/ But that's the thing with Tetris, you're always learning new stuff all the time :)

  7. I think I'm going for the PEXHDCAP.

    It's not like the budget options aren't plausible in any way, but I want to get my ugly, distracting body out of the way when I watch replays.

    Besides. I don't even know where I can get my hands on a Yankee candle D:

    If you use the PEXHDCAP, you'll need this:


    And if you want a direct audio feed, this:

  9. is it possible to play off the feed this provides? or way too much lag?

    Too much lag. You're pretty much going to have to play on a CRT if you want to be(come) competitive. Not sure what country you're in but in the EU you can get a simple supergun like the Smallcab Supergun to play via SCART, or in the US you could get a JROK Video Encoder for S-Video / Component.
  11. I'm probably going to go the line doubler or sony pvm since I'm in NTSC land. or a candy cab if I can ever find one. I don't have any hopes for competitive, but I kinda need the GM (in TGM1 at least) at this point in my life
  12. How much lag does PEXHDCAP have? Are we talking frames or seconds? I'm not curious about using it for playing, but audio/video sync.
  13. Muf


    Frames. Total round trip from source to display is probably like 3-10 frames depending on what you're using to display. Something like OBS will lag more than something like Media Player Classic (and again, that depends on the renderer you use, and the amount of buffers chained). Source frames will be timestamped though, so OBS should sync up the audio stream (in other words, delay it) to match the video.
  14. My... Brain...

    So I want certain pins to go not only into my JAMMA HARNESS LOOM, but also come back out, and enter a VGA thingy which is in a specific order?

    Okay, that makes sense.

    Solderless strats. Just put it together, works fine with my pexhdcap. though colors still slightly strong, might try a higher value resistor.

  17. I thought I was able to tackle this question, but it would be a lot of "the squiggle is this"

    I'll try anyways,

    The wavy line with an arrow pointed to it is a potentiometer (in other words, a dial) value 10k ohms
    the wave lines without the arrow are resistors, like the ones in the VGA picture. with their values listed as well

    and the half circles with lines are capacitors, ( I could never figure out if they are electrolytic, or ceramic, my guess here would be ceramic )

    so you connect a wire to pin 10 of the jamma, which goes to a resistor and a capacitor(now refereed to as CAP1) ,
    connect the other end of CAP1 to one leg of the POT and the other leg of the resistor to ground.
    connect the middle leg of the POT to another capacitor(now refereed to as CAP2), and the last leg to the negative side of the audio jack.
    the other end of CAP2 to the positive side of the audio jack.
    connect ground to the ground side of the audio jack and boom.

    either a literal boom or a subwooffer boom will happen, and it should be obvious if you were successful

    I hope that helps,
    I'm not very good at reading schema's myself, but it's something I'm trying to learn

    a soldering iron or a breadboard like Burbruee posted will be required.

    personally I like protoboards for something that's gonna stay put for a long time.

  18. My tgm1 board just arrived. So I'll need to be figuring all this stuff out. Probably not until April though when I move to my new house. I still need to buy the jamma harness and all the misc stuff.
  19. Ooooooh. That's not as bad as I previously thought!
    It seems a bit more straight forward now.

    So for this project, I will need.

    1. Protoboard - - BOUGHT
    2. Wire - - What kind of wire?
    3. Capacitors 10 u - - BOUGHT
    4. Resistors 47k u - - BOUGHT
    5. Resistors 220 u - - BOUGHT
    6. Potentiometer 10k - BOUGHT
    7. Audio jack thingie - - BOUGHT
    8. VGA thingie - - BOUGHT
    9. The damn capture card - - BOUGHT
    10. Soldering Iron - - HAVE IT.
    11. DVI-A to VGA adapter - - BOUGHT
    12. Aux 6ft - - BOUGHT
    13. Yankee Candle
    Is that correct? I probably need some stuff to connect wires together, right? How would I do that?

    I am COMPLETELY new to this. Mind is blown.

    I feel "ballsy" as hell just trying this. It's going to happen.
