Blackmagic Playback of Unsupported Frame Sizes is 2K and not 1080p

Previously when in a 3840x2160 23.976 timeline I would set "Unsupported frame sizes: Scale Down". I'm intentionally using an HD only output card from Blackmagic (UltraStudio HD Mini) and not a 4K card so the 4K timeline will be an "Unsupported frame size" I'm using a Flanders DM240 external monitor. Using this method the output signal used to be 1080p and all was well. Now that signal is 2K which makes the image on the monitor appear slightly wider as the image is being squeezed from top to bottom. The PC version of PP does not do this and previous versions of Premiere did not do this, they output 1080p when set to Scale Down.

There is no other way to monitor a 4K or larger timeline on an HD monitor. As an online editor it is critical to see the proper aspect ratio on an external monitor even when scaling down.

Mercury Transmit is great in that you can route video to multiple outputs at the same time.

However, this same capability does not exist for audio outputs.

The lack of multiple audio routing precludes the use of software based streaming encoders like Streambox Spectra to send out audio playback synced to its accompanying video, without completely disabling local audio playback/monitoring.

When I beta tested the Spectra plug-in with Premiere, I thought it was perfect for streaming editing sessions, but the lack of simultaneous audio routing ultimately rendered the plugin almost useless for anything other than MOS footage review or color-correction sessions.

I’m guessing this may be a more difficult problem to solve than it appears, since you probably need to have a way of reliably locking audio sync to the proper video output as well across multiple, simultaneous audio/video outputs. But having this feature would be very useful, especially now that remote workflows has become the norm.

When a project sequence gets round tripped from Premiere Pro to DaVince Resolve and back again (for mastering and final delivery), the graded files will usually be exported from Resolve with a suffix added to the file name. Same goes for in-camera generated proxies, they also often have additional characters added to the file name.

Premiere can then no longer automatically relink those files, because the file name doesn't match exactly. Relinking those files one by one is a pain. If not to say not feasible at all for longer projects.

So in the relink media dialogue, it would be perfect if we could check an option "ignore suffix/prefix". So Premiere would automatically check if the original filename is contained within the new file name and simply ignore the additional characters while batch relinking all footage. That would improve our workflows tremendously!

When I edit multicam it would be nice to have source window over transmit with all the camera angles. There is option for that now, but works on both, source and program window. If I want to see all the angles over transmit it works for the source window and i switch to program Window there are also all camera angles and program window as well. And i need to go and turn off option so i can have full screen program window over transmit. It would be nice to have option to show multicam angles only from Source window over transmit.

Dear Adobe,

I run a post-facility of six Premiere Pro edit suites, all iMac based, connecting once to a secondary working display and once again using TB2/TB3 Ultrastudio Mini Monitors to connect to a reference display.

I can see and feel a clear difference in playback latency when turning on or off the transmit playback monitoring to the reference display. With transmit enabled the latency when pressing play is measurably higher than if it is turned off. This is slowing down our work enough for me to just want to disable the reference monitor altogether.

We are running the latest driver release from Blackmagic Design on the latest Premiere Pro release right now. This problem however has been consistent over every version of the driver or Premiere Pro. I am not sure if it is the hardware, the drivers or Premiere causing the issues. It would however be fantastic to see it cleared up. Thanks!

I just updated all the programs through Creative Cloud into versión 2020. But Premiere Pro won't identify the installed version of After Effects as the 2020. The first 3 attempts I try to replace a clip for a comp in After Effects it did as intended but I couldn't do anything more, it was freezed. For the next attemps I reinstall both programs and now it shows me the message in the attached image "Adobe After Effects 2020 debe estar instalado para importar este archivo". I am curretly going back to the previous versions to try it.
I have all the creative suite programs installed in a diferent hardrive of the booting system. But they are in the same folder, as well as the Caché folder.

Found the issue but cant fix it. The issue is with how Premiere handles Arri Alexa Pro Res files. I dont have the issue with other media or once it has been rendered to ProRes HQ.
I have just confirmed that Adobe Premiere 2020 14.0.1 Does NOT work with Black Magic Designs products when working from Arri Alexa Pro Res Files. I tried other BMD devices and am getting the same results. Transmit to BMD devices creates flashes of green and playback that jumps forward and backwards rapidly. Repeatable.
Premiere 2019 does work without issue. Something was broken in the transition to 2020 in regards to Arri Alexa Pro Res playback via transmit to Black Magic Design Products.

This seems like a really arbitrary limitation -- what if I need to see overlays for stuff on V9 or A9 or above?! Currently I'm working on a sequence with 15 video tracks and 20 audio tracks, and that's tame for a workflow that often involves layers for storyboards, footage, graphics, adjustment layers, vfx, color, etc.

1. Should be able to read overlays from any existing track or all of them

2. Add a "Read From the Top Down" overlay option, that could function exactly like the "Selection Follows Playhead" feature when all the video selectors are turned on -- i.e. the overlay displayed is for whichever clip is under the playhead, highest up in the layer order, and has an active selector.

3. Allow better sizing and positioning options. The increments between font size options are waaaay too big, and because the size is also affected by the monitor it's transmitting to there's just not enough control to get it the right size sometimes. Let me just type in a number to choose my font size.

Also the positioning is difficult to adjust -- only having the three options of Top Alignment, Vertical Alignment, and Bottom Alignment is not enough, and often overlays are cut off because of sizing and positioning issues, especially with clips with long file names -- which are very common in post-production. Allow more control over sizing and positioning of overlays please!
