question

Will this scaler installed at a projector allow for smooth HDMI switching further up the stream? Does it send a constant native res to the display source? Currently running a 4x1 HDMI switcher into a projector but the HDCP handshake creates a very clunky switch between the sources.

Using a Powered HDMI Switch gets you where you are... What you need will be a Blackmagic Design ATEM 4K Switcher. Worth every penny!

question

Our church sends HDMI signal to 4 screens with an HDMI matrix splitter over CAT5/6 HDMI extender. Would this be able to take the signal from the CAT5/6 - HDMI receiver then convert it to the BlackMagic Production Studio 4k resolution and keep it synchronized wherever the input change in the matrix?Does it convert to PAL - 576i standard? (for the time we still need SD resolutions)
Asked by: Anonymous
According to the PDF Manual, available PAL settings include: EDID 1 - PAL Resolutions - 720 x 576p 4:3 & 720 x 576p 16:9, both 50 Hz. EDID 2 - PAL Resolutions - 720 x 576p 4:3 - 59.94 / 60 Hz. Yes we have it. No we don't use it. Why: Short Term expenditure. Very rudimentary device. Interface looks like Windows 3.0 and Non Upgradeable Firmware! The Native Resolution of Device: 1920 x 1080i 16:9, 50 Hz & 59.94 / 60 Hz. We used with an HDMI Powered Switch. Never tried to use it with BMD ATEM 4K. Why? Awkward space requirements. HDMI Cables are face mounted, not edge connected. Cannot Rack Mount unless mounted on Face of Rack. For the Money... & Long Term Investment: Look seriously at Decimator MD-HX Up / Down / Cross Converter or DataVideo DAC-70 Converter. We have and use the Blackmagic Design ATEM 2 M/E Production Studio 4K. The Two aforementioned Converters work well with BMD gear. Hope this helps.

question

Please describe the audio delay feature, what is the granularity of the adjustments ?I need to add about 50ms of audio delay from HDMI in to HDMI out.
Asked by: Chris
I do not think it has an audio delay feature. It would be nice if it did!

question

does it accept 720p24, 720p30 and frame rate convert up to 720p60 or 1080p60?
Asked by: Anonymous
Hi,I have not tested 720p24, 720p30 myself. But i am pretty sure that it will upscale any source you give to your desire format.Its the best i have experienced in the cases of upscale or downscale in professional video.I use this in a TV station to convert appleTV to blackmagic SDI conversation. Hope this helpsRegards.

question

I want to use with blackmaguc atem 1 m/e production switcher, my atem is set to 1080/50i, will it work ?
Asked by: Karan
We are using the Toolbox to scale the video from an Imac into the Atem Production Studio 4K. It works well at 720p. I have not tried 1080i as I would probably go to 1080P to overcome the interlace issues. If you are using it for live video you would notice a delay in the video. We are using it with video presentations so the delay is not noticeable.
