all articles in 'broadcast'

Let’s talk about mice teeth

We have had a lot of questions on our forums about interlaced video, so I thought I would write a series of articles to clear everything up once and for all! :-)

Where did interlacing come from?

Back in the day, when me and my buddies were developing broadcast television, we were going to model it on film, which took a sequence of photos of reality, so, if a blue circle was moving from left to right, two consecutive frames might look like this:

Instead of the 24 frame per second …

Monitoring your work in Final Cut Pro

When you’re EDITING, you can make good decisions just watching the Canvas Window on your laptop.

But for color grading, it’s critically important to watch your show on a monitor that’s displaying an accurate image. Monitoring is important because all your color grading work is going to be off if the monitor you’re watching while you work is not telling the truth.

Think of all the ways viewers might watch your project. If you’re delivering on DVD, your show might be watched on plasma or LCD TVs, projectors, or older CRT TVs - but they also might be watching the DVD on …



HD Monitoring ideas

You’re shooting with your new HDV or HD camcorder, and the footage looks amazing! But are you really seeing the full picture?

Not unless you’re looking at a high definition monitor. But professional HD monitors are still expensive.

So, here’s an idea:

You can buy a LCD TV/computer monitor (the lines are being blurred more every day) that can be used for three different purposes:

1. While shooting, you can run component (like from the Canon XL H1 or XH A1) out of your camera into component input on the LCD to monitor what you’re shooting in full, pixel-for-pixel …

Do I need a studio monitor?

If your projects are going to be delivered on DVD or broadcast, it’s important to have an accurate studio monitor on your desk so you can see your project as your viewers will see it while you’re editing.

Why?

First, many editing programs show you a low quality “proxy” of your timeline, so you can’t judge color correction, brightness, saturation, contrast, how titles or graphics will look, or any other aspect of the picture accurately.

Can I just enable a second computer monitor to show video and that will work?

With some editing programs, you can enable a second monitor to show a …

What is the best way to do multi-camera shoots?

I have shot multicam concerts locking up timecode by beaming wireless audio SMPTE timecode to all cameras and recording it on Ch 2, but I can tell you it was a big hassle and a waste of time.

My recommendation for multi-camera shoots is to either:

1. Use TOD (Free Run) Timecode

TOD (Time of Day) timecode is a switchable option on some recent camcorders. With this option, you can synchronize multiple cameras, then each camera can start or stop at will, and the timecode always reflects the current time, not the tape position, so the …

Chroma Key in HD

Click on the picture above to watch the movie!
We want to give you the opportunity to explore the art of keying. Taking the background out and dropping in something different is a special effects technique that has been around for years. However it was not until recently that we have been able to get broadcast quality results in both a fast and inexpensive manner. Quality Chroma keying is now for everyone.

Possibilities

Think about being able to shoot a background plate in Hawaii to use in the middle of a New York …



What are the legal issues about shooting in a public place?

You must obtain a model release from each person whose face is recognizable in the photo. Also, location releases are needed for many properties.

Bert P. Krages II has posted a PDF with some information here, mostly with your rights as a private photographer.



Fox’s “24″ tests HDV cameras

On the Canon H1, Rodney Charters says:

"We did manage to get footage out of the Canon and upload it to the D5 no problem. And it was this footage that we viewed at Level 3 post, where it made an amazing comparison against the 35mm dailies. The imagery was almost identical except for that nagging problem of almost infinite DOF. It confirmed our belief that this was the sharpest and best picture of the bunch."
