As we pan across a scene, some parts of the scene enter one side of the frame, and some parts leave the other side, but the section of the image in the middle just moves laterally. Motion vectors allow the encoder to describe movement within a frame. For example, most interframe formats use something called motion estimation and motion prediction. Interframe compression uses a variety of techniques to encode the changes from one frame to the next. Why would we go to all the trouble of sending a complete image each time when all we need to do is describe what changed? A panning shot primarily consists of the same image, just moving sideways. A talking head video primarily consists of a moving mouth, and perhaps some blinking eyes. Interframe compression is based on the assumption that any two sequential frames of video are unlikely to be all that different. And you need to hope that those miniDV tapes won’t spontaneously combust. Even worse, you need to engineer motors, write heads, and lots of other bits that work reliably at four times the speed. Suddenly your 60 minute tape is only good for about 12 minutes. Why not just put HD on those? Well, HD is more than four times the number of pixels, so we need to run the tape four times faster. The world already knows and loves cheap and cheerful miniDV tapes. Let’s say you want to implement a tape-based HD acquisition format. Hardware solutions don't really work for me at the moment.In our last post, we covered intraframe compression – easy to edit, high quality, and inexpensive to implement. I ment that none of my monitors had SDI inputs, not my decklink card. So I have SDI output, I just have no inputs.
PROGRAMS LIKE SCOPEBOX WINDOWS
I agree with you that the build-in scopes from Avid need to be in separate windows so that you can put them in whatever size wherever you want. I am still using the UltraScope and it suits me well. The UltraScope has a sharper view, and a real Tektronix is sticking even more further out I guess. I haven't used the Avid ones anymore since a couple of years because they reacted too slow, so I don't know how they respond and look right now in the latest version. Scopes all work the same, but the Avid ones are too soft to watch at with their low resolution. They come at £589, but you also need an SDI output from your Avid. All you need to do is take an SDI output from your Avid and feed it into the UltraScope.īlackmagic Design has SmartScope Duo 4K. It actually has nothing to do with Avid itself. Yes, you can run the discontinued UltraScope from Blackmagic Design with Avid Media Composer 2021. Most modern cheap PC's will run this card. You need a second computer with minimal specifications to run this card.
PROGRAMS LIKE SCOPEBOX INSTALL
I also forgot to mention that you cannot install this in your editing machine.
PROGRAMS LIKE SCOPEBOX DRIVERS
Yes, the UltraScope is just a PCIe card with drivers that you have to install. When you do not have an SDI output from you Avid system this is no solution. I'll try the NDI option though and get back to you I really wish we had a docking panel for scopes, that would solve this for me. Likewise, I don't have enough PCIe slots for a second I/O card. I don't think this would work as it has no inputs, only outputs. I have the blackmagic decklink IO monitor. I should add that I've never tried these methods myself (as I have a Leader external scope), so it's all theory on my part!Īh I see. If you right-click on the HD/SW icon in MC, you should see the NDI option. Decklink SDI 4K), you link an output to the input and set the Omniscope to use the SDI input as it's source.Īvid also supports NDI fuctionality (since 2018.7) and should have been automatically installed (unless deliberately excluded), so it's possible you could use this device interface to input into Omniscope. I'm reading this as if you have an input/output card (eg. Input card - to receive the signal back in Nobe OmniScope Output card - to send the signal out of DaVinci Resolve To make it work you will need 2 I/O cards (or 1 multi I/O card - see below): This can be achieved by looping the SDI/HDMI signal back to the same computer so that the signal is visible to Nobe OmniScope. OmniScope can be used on the same system as your DaVinci Resolve installation without using the OFX plugin but rather through SDI/HDMI signal. But I didn't find it to be compatible with Avid Media Composer.
