Forgot to share this pic to here. My 15 seconds of fame as a +Reviews on the Run camera operator.

Behold, the Nikon D800 and NanoFlash and Zoom H5 franken-rig, with BP-U SWIT battery powering the light, H5 and the NanoFlash at the same time. Handheld only. H5 is held by a Noga Cinearm, Light is a modified Flolight Microbeam 128 that can take Sony BP-U batteries. That's a Sony ECM-XM1 I'm borrowing for this shoot.

The troubles of lacking a cost-effective DVE device for source scaling and picture in picture. (cc +Alex Lindsay)

So our current setup has us trying to scour for a software based DVE that can process native interlaced (1080i) and output back a Blackmagic card. Turns out, there are none that are available that do what we want cause they're hardware based (AND RARE for our budget range) or they lack native interlaced processing, OR if you do it via the graphics card, no control of vertical sync to eliminate screen tearing...

Our problem lies in that we currently have the lowest end model of the Blackmagic Production Studio 4K that lacks 2D DVE hardware inside, so the most cost efficient way is to do it through software, but passing it through Wirecast will remove the native interlaced processing and differentiate the motion.

The closest one that is under continued development is OBS studio. It has options to work in drop-frame formats and I already pitched to the developer our workaround for native interlaced workflow, being you de-interlace with Yadif2x on Blackmagic input, process in 1080p59.94 (60p) and then send back to another Blackmagic card as 1080i. The Blackmagic does the Vsync for you, or if you want to use the GPU in projector mode, there should be a "Alternate Vsync" option like in Media Player Classic - Home Cinema to get the Vsync to a proper spot.

This is for an upcoming convention which is happening in 2 weeks. I will have a very hard time to convince my team a hardware swap should be done and right now all solutions I've seen are all so close, yet so far. We may be unable to do DVE effects at all.

What's so easy in Xsplit and OBS to go to a stream is not so easy to do with SDI hardware in a cost efficient way. THERE HAS TO BE A SOLUTION that doesn't sacrifice native interlaced processing.

One of the few HoloLens prototypes Microsoft had has been destroyed trying to be sent into Space on the SpaceX Falcon, which disintegrated on launch: https://twitter.com/ShuttleAlmanac/status/615164705225637889

Disclaimer: They edited the video on a 60p timeline then sourced their footage in 24p. This is not a true demonstration yet.

4K 60p YouTube videos are coming. Since they want to force everyone on VP9, make sure your GPU or CPU has hardware VP9 decoding acceleration at 4K and 60 frames. (those are likely a year out, so for now, only software rendering can play it back properly on a high end system)

Another example of terrible video quality in the form of vertical video syndrome AND 240p combined. This went viral too. All TV stations had to crop the video further to lessen the vertical video syndrome effect and it made the quality worse.

LEARN TO HOLD IN LANDSCAPE FOR VIDEO!

Microsoft to slip user-tracking tools into Windows 7, 8

Worried about Windows 10's deep-reaching user tracking? Some of it's coming to Windows 7 and 8, too:

Here, have a speedgraded shot from the Nikon D800 (Cineflat profile) in low light (ISO 2000) from the NanoFlash @ 100mbps Long-GOP. Audio-wise, my rig has a Zoom H5 that pipes directly into the NanoFlash. (cause on-camera pre-amps are for the weak) #postchat

I may share a photo of the rig later if people are interested. It is unfortunately a handheld only franken-rig with a Manfrotto 492LCD and a Noga arm. (Noga takes the tripod hole spot)

Dated, but they do the job. Especially since the Blackmagic SDI converters have been on almost for a couple of years.
 
The TWiT Brick House is equipped with over three dozen video cameras--all Canon VIXIA, models HF G10 & HF G20.

I just signed this. If you care about your privacy, you should too. https://killc51.ca/?sid=1148989
The government has just rammed its reckless, dangerous, and ineffective Bill C-51 through Parliament. Tell Ottawa leaders they should promise to repeal this extreme legislation.
