Scott Wilkinson

Scott was at the SMPTE Tech Conference this week and saw the new high dynamic range video displays. HDR video is the latest hot thing, and it creates some incredible high dynamic range of the image. Leo says our brains do HDR really well, but it's a challenge in video. Scott says that high dynamic range cameras are going to be needed and the latest generations of digital cinema cameras have over 14 stops of dynamic range. So they can do it. It requires 12 bit color, but the current video systems are only 8 bit.

Why does my internet connection stop when I'm uploading video?

Episode 1124

Vance from Florida
YouTube

Vance says that when uploading data, it completely hogs his bandwidth. Leo says that's usually true. If he saturates the upstream bandwidth with videos, the connection can't do any other internet activity as a result. Can he split the bandwidth to prevent that interruption? Leo says that's why bittorrent works better. There really isn't a way to do it unless his router supports it. Leo says it may be more practical to set the videos to upload as he gets ready to go to bed and let it run through the night.

How can I keep my videos from crashing my computer?

Episode 1111

Neil from Hermosa Beach, CA
Video

Dennis has a computer that crashes whenever he watches videos. Leo says to check for the latest video drivers. Leo also recommends using Google Chrome because it gets updated to the latest Flash drivers automatically. Dennis could also try closing tabs to reduce the memory footprint. He should also make sure that hardware acceleration is turned off. That can often fix the problem.

What's slowing down my computer while rendering?

Episode 1110

Tim from Cape Cod, CA
CPU

Tim uses Adobe Premiere CS6 for editing video and wants to decrease his rendering times. Leo says Tim needs to figure out what the weak link is in the chain that's causing the bottle neck, and it could either be the processor, the graphics processor, the RAM, or the hard drive. Boosting his video card will help. Since he's boosted his RAM and installed an SSD, Leo has a hunch it's the graphics processor. If it's slowing down while encoding, that could point to the CPU.

How can I record better audio for YouTube videos?

Episode 1106

Mark from Moorsville, NC
Beachtek adapter

Mark's son is doing YouTube recordings of his drumming. Leo says that kids using YouTube is all the rage now and a point and shoot camera does spectacular video. But the audio is another story. Leo says that a BeachTek adapter with a minJack out/XLR in will allow him to use a Sure SM57 mic. He'll want to sync the audio as well by making a loud clap at the beginning so he can align the audio and video tracks properly. He'll also want to think about lighting as well.

How can I get the best quality interviews on Skype?

Episode 1104

Don from Mission Viejo, CA
Skype

Don wants to create a video montage of testimonials that are high quality, but not intrusive. Leo says having them use the best camera they have or sending them a camera guarantees that the quality will be the best and consistent. Oprah, for instance, has a “Skype kit” which they send ahead of time to those they interview on Skype. Leo suggests the Canon Vixia, the Lowell Ego lights, and a tripod. Written instructions, and all into a Pelican case. The whole kit wouldn't be more than $1500. He can also hire a local videographer to produce it for him for a nominal freelance fee.
