A revolution in HDV video production? by Peter Garnish

With the advent of new technologies in DVD and digital video production, corporate production houses are poised to start creating much higher quality videos at a much lower cost. Recent HDV model releases from both Sony (HVR-Z1P) and JVC (GY-HD101) has seen high definition video production become available to smaller production companies. As a result we are now able to produce videos at full 1080i HD resolution, and with the release of Canon's hugely anticipated XL H1 get full HD-SDI uncompressed video straight from the camera.

The Canon XL H1 is long awaited follow up to the industry stalwarts the XL1/2 series. It is the company's first foray into HDV video and is also the first camera in this range to feature uncompressed HD-SDI output. What this means is that for the first time video producers can purchase a relatively cheap camera (less than US$9000) and edit full uncompressed video, without the disadvantages of using HDV and an intermediate codec to edit.

Whether you are in music video, corporate video, DVD or multimedia production, you now have the opportunity to compete with the larger companies with much higher overheads. This is great for freelancers and the industry in general as productions can be completed at more competitive rates and the huge investment in both camera gear and edit suites doesn't break the bank like it used to.

Remember the good old days when a BetaSP rig cost you $80-$100000 and about the same for an Avid setup? I for one am sure happy about the reduction in expenses and look forward to seeing some amazing work from everyone with all of this new gear.

High Definition Update by Cal Barton

HIGH DEFINITION UPDATE

High Definition Update - Paul Wheeler Interview

In July 2005, I wrote an E-Zine with the headline "High Definition - When?" At the time we saw little demand for HDCAM equipment aside from some clients in the U.S. Seven months later, the situation has changed dramatically. We added two Sony HDW-F900 HDCAM camcorders (Sony's top of the line HDCAM camera for television and/or cinema) to our stock in January 2006 because of growing demand and see this as the beginning of a trend. And we have just taken a booking for a multi-camera shoot in March with six HDW-F900s.

Interview With Paul Wheeler - Soon Available on DVD

With this increase in demand, we recently hired Paul Wheeler BSC, a highly experienced film and digital cinematographer who wrote the book, "High Definition & 24P Cinematography", to run some workshops for us. While he was here, I interviewed him. We are going to make available DVDs with an edit of the interview. If you'd like one, contact me at cal@procamtv.com.

BBC - Drama and High Definition

One of my first questions to Paul was about the apparently sudden leap in demand for HDCAM. Paul's response: "Five years ago the BBC was saying within two years everything they record will be on high definition. Three months ago they said everything we record in two years time will be on high definition so trying to predict what happens is very difficult. The BBC who wanted to move in that direction haven't moved as fast as they wanted to. But that's not a technical problem. That's a problem with persuading producers that using a new technology is safe. And I think this year (2005), we've just begun to see the confidence in the system and I'm very hopeful that we're now going to see a cascade effect. Where a couple of very expensive period dramas have been done on HD, they look exactly like very expensive period dramas. And that to me is a huge starting point that I was hopeful would have happened a couple of years ago."

Sky TV and High Definition

Sky TV has also said they are on track with plans to launch HDTV in 2006. BSkyB's Chief Operating Officer, Richard Freudenstein, said recently that the dramatic improvement in picture quality would help BSkyB achieve its target of ten million customers in 2010. "Innovation and technology leadership are at the core of the Sky brand," he said. "By introducing HDTV, our ambition is to raise the bar again." BSkyB expects that sales of "HD Ready" TV sets will accelerate as equipment prices continue to fall and the availability of HDTV programming grows.

Nonfiction and High Definition

Paul says the increased use of HD in documentary and factual programming has been stronger than in drama. "We have had more factual programmes made in HD than we have had fiction and I think the main drive there is this fact that you can sell it round the world. You can only really sell drama if you've made it in England to an English speaking nation but you can change the commentary of factual to any language very easily and I think there is more potential for international sales of documentary work or factual therefore those advantages of the transparency of moving from whatever you've shot it in to whatever you want to sell it in are an even bigger advantage."

Sony HVR-Z1 (HDV) vs Digital Betacam

The most popular high definition camcorder is the Sony HVR-Z1. This is meant for low budget shoots and the camera has replaced the Sony DSR-PD170P. The main advantage is the Z1 has a wide screen chip so shoots true wide screen. The PD170P does have a wide screen setting but because it has a 4:3 chip this setting produces inferior images to the Z1. Most of our clients record in the DVCAM rather than the HDV setting when they use the Z1 and get excellent results.

In some articles I have seen the Z1 compared to the Sony DVW-790WSP camcorder with the conclusion the quality of the image is similar. According to Paul: "If you take the output straight out of the Z-1 and stick it in a decent monitor and do the same on the B-channel with a Digi-Beta and you flick between the two you'll be fairly impressed. But there are other issues in why you choose a camera. One is the recording format and the Digi-Beta format is much more stable and robust than the M-Peg 2 compression used in the HDV process." This, Paul says, is particularly a concern in post production, especially if you're doing a "fair bit of post production."

The other issues to consider are the lens and the actual robustness of the camera. The lens on a Digi-Beta is far more versatile and quicker to respond than the lens on a Z1 and if you are shooting in even slightly adverse conditions the 790 is made of far sterner stuff.

Paul's view is to "think of (the Z1) as a replacement for your PD170 but don't think of it as a replacement for the highly professional, very robust, very strong recording process of the Digi-Beta. It's not."

More on the Paul Wheeler Interview DVD

The DVD with an edit of the interview with Paul will include a discussion of the following:

* Growing use of High Definition camcorders * Z1 vs Digital Betacam * Brief summary of the different camcorders: 730, 750 and F900 * Progressive scan and interlaced recording * 720 vs 1080 * Setting the camera correctly for post production

Summary

High definition is definitely here. I have never seen a format take off so quickly. We experienced a marked increase in demand in January and interest and inquiries are growing. I recommend you learn as much as you can about the High Definition cameras available, the range of settings you can shoot in and what accessories are commonly needed. The July E-Zine covered much of this, the Paul Wheeler DVD covers more and the next E-Zine will cover commonly needed accessories.

Until then, happy shooting!

An interesting trend indeed. It's about time the industry got serious about pushing HD. The trend has swung HD's way increasingly over the past few years, but the consumers are still in the grey area when it comes to fully committing to the standard. The trend of buying HD sets and not having HD content for them is more prevolent today than ever. HD support will increase the market's demand for it, hence giving more work to the people who provide it. NAB will reveal new trends and show us all where the industry will be focusing it's attention. Let's hope the quality of the products that are released are as inventive as they have been in recent years.

AVCHD will be making a strong push this year. The format totes higher quality with higher compression via the MPEG-4 standard

Arqiva installs Zandar multiviewers for European HD trucks

Arqiva, a provider of transmission services for broadcasters and end-to-end media solutions for content and channel providers, has acquired 48 Zandar Predator HD8 MultiViewers to help produce live HD broadcasts of Championship Football for Sky Sports and its Sky HD channel.

The compact Predator units are installed inside two UK-based mobile production (OB) trucks, 24 for each, making it one of the largest single HD8 OB projects completed. Sony Professional Services installed the systems on both trucks.

On each truck, 10 multiviewers are installed in the production area, 12 in the videotape recording area and two for the audio mixing section. The Predator HD MultiViewers feature native HD input processing to display HD images up to 1080p. The multiviewer also offers low frame delays (less than one frame) from source to output.

The Predator HD8 accepts and auto-detects up to eight SDI or HD-SDI inputs with a high quality DVI output to the LCD displays up to 1080p resolution. The systems feature Zandar Dual Head (ZdH) display to drive one or two displays independently or configured as a virtual monitor wall, with spanning capability. ZdH is particularly ideal in space-restrictive OB vehicles because the system saves on rack space by combining two MultiViewers in a compact 1RU enclosure.

Miniature HD video cameras in Daytona race

The WW20000BA H.264 HD encoder from W and W Communications was suc cessfully used by Broadcast Sports inside its onboard wireless HD cameras for transmission of live video feeds from racecars in this month's Daytona 500 race. The race was the first ever Daytona 500 race broadcasted in HD. Broadcast Sports, a wholly owned subsidiary of L-3 Communications/WESCAM, delivered the compact, wireless HD broadcast camera systems that were mounted in the cockpits of several cars in the race.

A COFDM microwave transmission link provided non line-of-sight transmission of the AV bit stream to production and satellite uplink units.

The WW20000BA video encoder was used in these camera systems to compress the video in HD broadcast quality at bit rates low enough and with very low latency, to make live coverage in HD over wireless links possible from cameras within the racecars.

'The successful broadcast in HD of this month's Daytona 500 race was a major milestone for the live broadcast industry'.

'Without the WW20000BA H.264 HD encoder from W and W Communications and their commitment in supporting us, we would not have been able to achieve this milestone'.

'This first success is opening the door for BSI to bring viewers world wide live sports coverage in HD', says Adam Toner, Engineering Manager at Broadcast Sports.

The H.264 standard produces superior results at lower bit rates compared to the older MPEG-2 and MPEG-4 video compression standards.

However, the significantly higher computational complexity of H.264 poses a major challenge in terms of power and footprint.

BSI found the solution to this dilemma in the WW20000BA encoder from W and W Communications, which runs at 110MHz only and comes in a single chip implementation.

The WW20000BA encoder compresses 1080i/p HD video at 2x lower bit rates and 15% better PSNR than MPEG-2 HD encoders.

'The combination of our video encoder expertise for low delay applications, combined with BSI's HD camera and microwave transmission expertise made it possible to achieve this milestone'.

'W and W Communications is proud to be partners with Broadcast Sports and to supply the company with the industry's best H.264 HD broadcast quality encoders', says Kishan Jainandunsing, Vice President Marketing at W and W Communications.

The WW20K H.264 codec chipset from W and W Communications consists of the WW20000BA encoder and the WW200001BA decoder.

Encode-decode tandem delay is less than 35ms or about 1 frame at 30frame/s with performance very close to the H.264 Joint Model.

The W20000BA encoder integrates an advanced context-adaptive noise reduction filter.

This not only reduces noise in the source video, but also improves the encoder's compression efficiency significantly depending on the video content.

Accurate constant bit rate control guarantees video quality versus available channel bandwidth over broadband wireless transmission links.

Software upgradeability of the chipset makes it easy to apply field upgrades.
