Hi hi,
I hope I’m asking this question in a way that isn’t too redundant, or has been already answered. In anticipation of the memory palace’s arrival:

Are there any drawbacks to using a run of the mill dvi-d to HDMI adapter (link to example below) before going I to a recording device (like hyperdeck shuttle ssd) - and out to a monitor?

I 'm all about the high quality conversation from analog to sdi, but my wallet can’t take that big of a hit right now. At the same time, I’m trying to get a recording of a higher quality than can be achieved by USB dongles.

Interested to hear your thoughts on wheather something like this would play nice with memory palace:

DVI-D and HDMI carry the same information. They are just a different connector. HDMI is a more expensive connector. So, the adaptor should be fine. According to the MP page LZX will supply the MP with one.

“DVI-D/HDMI video output supporting 480p/576p SD progressive output. DVI-D to HDMI connector adapter included. [ Designer Note: We plan to enable other output video format options on the DVI-D connector.]”

About the Hyperdeck: At this point the MP looks to only output 480 progressive. So it is de-interlacing the incoming interlaced signal that you are feeding into the MP. It is not scaling to 1920 x 1080. So just confirm the Hyperdeck will accept that format.

If you want to upscale to 1080 you need the Hyperdeck to do that in your proposed signal-flow. You would need to confirm that it can do that as I am not too familiar with that particular product.

so I’ve just received a hyperdeck shuttle!

at first I tried simply sending it a feed from my switch via an ambery vga/component => HDMI transcoder (I don’t believe it is being sold anymore can’t find any info)

no luck :frowning: well some luck as you can see the whole image is green

at this point some of you probably already know what the issue was

so I tried the component out from the LZX rig through the ambery transcoder again just a green version of the lament configuration

I did some research and found that the hyperdeck is expecting the HDMI source to be YUV video not RGB so I had to start looking at all the manuals of my devices to see what would allow for going from RGB component to HDMI YUV

my first thought was to use the BMD intensity shuttle
while it isn’t a practical setup unless I was wanting redundant video recording (one to computer and one to SSD) I still wanted to see if it would work

and it did good news! (the source this time from a VHS player into a V440 mixer out via the s-video program output)

ultimately I’d like to be able to record to send video out from computer (intensity shuttle) and record straight onto a SSD (hyperdeck shuttle)

so I have a couple extron scaling boxes I bought for around $20 each off ebay and while looking back through the manual one stood out as it would happily change the colorspace from RGB to YUV via its on screen menu system

the one I ended up using first worked so I didn’t end up trying the others yet extron RGB-HDMI 300 A (i think “a” allows for 1/8 stereo audio input alongside the component/VGA input and even has some audio delay built in for proper lip syncing!)

so I went out with component from the LZX rig => a component to VGA adapter => the extron 300 HDMI box => the hyperdeck shuttle => the viewing monitor

I know this is a big rambly but I’m hoping that somebody will find it useful

If you have an old PC or MacBook, a cheap Video Capture device like the Digitnow (22.99€ from Amazon) seems to work fine.

Initially I was considering Blackmagic and Elgato, but I’ve read mixed reviews about the results using MacBook Pro and USB-C, and didn’t feel like throwing 150€ just to see if one of them works for me.

I doubt this Digitnow would run on my MacBook Pro, but for less than 25€… In any case, I was thinking in using the MacBook Pro for sending video, Lumen, etc., into the Visual Cortex, and the old Mac for recording.

The quality seems pretty good. If interested, I could list the codecs included and the maximum resolution. In any case, way better than my up-to-now attempts at recording from the TV (which included multiple unwanted reflections, knocking the camera off a few times, and the “textures” one gets from filming from TVs… though they also have their charm). Anyway, for now it’s just for fun, to record some experiments with the Visual Cortex. I have no illusions of becoming a Pro anytime soon.
