ATEM Switcher: Upstream & Downstream Keys

This obtuse 1976 terminology is just ludicrous in 2023.

THANKS for that perfect explanation!! I now really understand the difference and when to use which one 👍🏼

Thank you for this video! You're an excellent teacher

This video is so informative. Found exactly what I needed without scrubbing through a 45 minute vid. BUT... how to create a pre-multiplied graphic by exporting directly to the ATEM from within Photoshop was worth the price of admission!! Thank you.

This file doesnt give transparency on my DSK with the PS TOOL; what goes wrong?

You said there is only one media player, but you can load multiple files onto that media player, correct? Like if I had 4 presenters who all had their own animated gif to display upon walkon, how would I go about cycling through those gifs? Is there a shortcut on the controller or would I have to manually load each file from the software?

Excellent !! I learned something on this video I should have learned 10 years ago !! Bravo !!!!!!!

The Atem option was not available in my export menu on Photoshop, reinstalling ATEM software now to see if that fixes it.

Very good tutorial!

Is good to under stand. Down stream key means we use input

One of the clearest explanations of this topic! Thanks!

bravo! great from Cote d'ivoire Africa

Fantastic Explanation. Well done.

Hello do you have any tutorials for the ATEm 1 M/E Production Studio 4K

Good 👍👍👍 your explanation is very simple and straight,l like this

Such a great explanation of these key elements! Thank you so much for sharing!

Thanks!

Thanks for this, now got a better understanding of the differences! :)

This is great information to have when first starting out with lower thirds. The presenter is very easy to listen to and made understanding upstream and downstream easy. Thanks and keep up the awesome training videos.

We produce live streams of high school sports. We used to have a Tricaster Mini (until it died) and it was easy to update a score while we recording due to the built-in software. It looks like the ATEM software here does not allow that. I've found a way to update a graphic using Preview (of all apps) but it still requires a LOT more steps than the Tricaster software did. What is the best practices workflow to do this with the ATEM software? There's got to be a simpler way to do this. Bare in mind, this is for high school students to operate, not professionals.

how do you connect the atem to the computer to remote it with the software, via network or via usb?
I have problems if I control it via Usb C and I also take the video stream as a webcam, the Atem jumps as if it had no synchronisms.
If, on the other hand, I only use Atem without the software, or if I control it via the networ, I have no problems. Thanks.

Very good explaining the difference in up and downstream keys. Thank You! Clear screen and no BGM!!

How to make L-band graphics in different size in black magic switcher

Kindly tel me how play 2 macro same time

Kindly make a video and upload

Hi I want to know how to make a macro in atem one me black magic switcher.

Is there a way that you can select which image is picked from the media pool? Say if you wanted lower thirds for multiple presenters?

Thanks for sharing!

This was a super helpful tutorial. Even though I’ve been a TD for a long time, the ATEM is different and your approach is spot on. Thanks for taking the time to make such good, informative content. I very much appreciate it!

I must say this is the best Explanation I have heard for the longest time-clear and precise.A+A+A+

How can I configure a key, either up or down, to use an external input as the video source? We have side third graphics during our presentations where the graphic middle and right is transparent but the graphic on the left is not keying correctly. Should I use up or down?

Great overview! Thank you! Is there a way to "preview" the DSK like you can with the upstream key?

I watched the whole thing and never heard a definition of upstream vs. downstream key. Still confused.

Really helpful - we were using the luma key for church Sunday and kept going off between transitions and couldn’t understand. You’ve just saved me a lot of work - thank you 😊

Thanks ! That's great explaination for something i didn't understand until now

You have the ability of explaining complex things, simply!. 2DaPoint, I'd say! Thank you.

thanks, wholesome and very clear explanation.

Thanks for the Tutorial, you gave me some new ideas, however the Lego Modulars in the background made my day :)

great video so, helpful!

Thanks mate that helped a lot

Thank you so much for this incredibly detailed info, I have looked around at other videos trying to get this knowledge and couldn't find it, but here it is! I'm pretty sure everyone feels the same, great job!

My question finally got answered. Thank you so much!

this is so helpful thank you

Thx for the easy explanation!!! Just great!!!

Nicely done!

This is really good. Just the perfect level for explanations :-) Thanks. I suscribe

Very helpful video. But can you demonstrate what will happen if the "Pre Multiplied Key" is not checked? I'm a visual person and it would explain why we should and should not check it.

I have watched your vid 20 times and still dont understand how to use downstream key
