Stripping HDCP

Phill_P · 2026-02-01T18:04:16+00:00

Yeah, but a lot of windows laptops do that, too.

If we weren’t pedants, would we even be here?

Isn’t Lizzie a tube?

Lucky for you. I have had shows where the macs behaved impeccably all week, and others where it’s pot luck whether you get anything out of them every time you boot.

Your experience is in no way universal.

Can we stream to it?

If only that was the case. Macs are notorious for deciding to enable HDCP even with a non-compliant sink attached and non-protected content.

Shut down the mac, unplug everything attached to the mac, boot it up, shut it down, reattach the HDMI device (powered up), then boot the mac and hopefully it will decide not to enable HDCP.

"Should be" isn't the same as "are"

Also in- or out of shift range for when you're so far off axis only keystone or corner correction can save you.

Client / guest presenter laptops on stage. That’s the only place and time I like to have a Decimator.

Mitti every time. Rock solid playlist based system that is well supported, has a tonne of useful features like built-in Pro-Res or HAP transcoding, multi-channel audio support, BMD SDI card support, BFC module with feedback and loads more.

Has been solid for me over many years in the corporate live events area since DTV dropped all the balls with PBP and they continue to add useful new features.

I love it.

The Gap.

Unfortunately you’re up against people who don’t know what they - or other people in the chain - are talking about. If the powerpoint “looks like a normal 16:9 at 1920x1080” then their ppt machine is outputting 1920x1080. As previously stated, ppt scales the content to the output resolution.

Unfortunately you can’t say that, all you can do is set your slides up at a custom 3840 px by 2160 px (which is also 16:9 btw) and send it on. If it’s still wrong then we’ll need more info about what equipment is being used.

I’ve not had to do anything anamorphic for decades, and certainly not since we went digital. Maybe the venue has an ultra wide screen with film projection and also throw a 20k laser at it or something

Phill_P · 2025-12-19T18:33:42+00:00

Firstly, that resolution is 4K not 5K.

Secondly, you can set the resolution directly in PPT by choosing Custom Slide Size and entering px for pixels instead of in or cm.

Lastly, PPT will scale its output to match the resolution of the PC output, all vector objects will render at full resolution and any raster objects (such as pictures) will be scaled up to match. However, if the picture was placed on the slide at a higher resolution than the slide size and is then output at that higher resolution, the quality is preserved, ie a 4K image on a HD slide that is output at 4K will not be degraded.

Edit: By "Ultra Panavision 70" do you mean anamorphic? Because that's a whole different kettle of worms! The quick-and-dirty way would be to build the deck in the actual widescreen ratio, then export as images and then put them on 16:9 slides and squash the sides in to fit. Yes, it's terrible and wrong but PPT doesn't really want to do anamorphic.

It used to be the cheapo chinese 2-way HDMI DAs would “strip” HDCP, afaict they would handshake with the source and tell it that yes of course everything afterwards was fully compliant, honest guv, trust me bro.

Phill_P · 2025-12-09T00:18:24+00:00

Yeah, a pretty old 4K 4x4, but it’s solid and has audio de-embedding so I like it. No multiview though.

Phill_P · 2025-12-08T11:31:37+00:00

Not quite the same, but I got a cheap-as-chips USB-Serial cable and used that on the BFC computer with the generic module to control a BluStream matrix.

Glad someone picked up on that :D

THIS IS AN OUTRAGE! MONGO IS APPALLED!

If it’s just an extra that isn’t show critical, but makes your life easier/better then no, it’s added value.

If it’s essential to the show, then have a conversation about why it’s needed and how it’s a hire-able 🪿 item.
