Testing the Canon HV30 for Youtube Video
2 Comments Published by Matthew Jeppsen March 24th, 2008 in Cameras, Formats, Research, ReviewsCanon’s new HV30, the update to the revered HV20, is the only camera in this price range to offer three major framerate modes: 60i, 30P, and 24P. Canon has suggested that the 30P mode is ideal for online video creators, since most online video is cut to 15 frames per second and that allows the encoder to simply remove every other frame, resulting in better quality video. Or so goes the theory. Camcorderinfo recently tested this assumption with Youtube, and has provided side-by-side examples of their test footage so you can compare it in realtime. Check it out.
The HV30 is available at B&H, currently at $899 with the $100 instant rebate. Purchases made via that link help support FreshDV at no additional cost to you.
Sony Z7U vs Z1U vs EX1 Low Light Performance
0 Comments Published by Matthew Jeppsen March 21st, 2008 in Cameras, News, ResearchDavid Perry has posted several framegrab comparisons that show the low-light abilities of the PMW-EX1 and HVR-Z7U next to the venerable HVR-Z1U. Aperture and other settings are not stated, but it is implied that they would match across the cameras (it would be nice if we knew what gamma curves were engaged, if any). Update: For an alternate take on these images, read this post by a respected Sony HDVinfo member (full thread here).
B&H has the Z7U in stock at this time, listed at $6,299.95 and the EX1 listed at $6449. At this time you can also order the S270U, listed at $8,499.95. All purchases made via those links help support FreshDV at no additional cost to you.

Best Practices for Slow Motion in Final Cut Studio
0 Comments Published by Matthew Jeppsen March 18th, 2008 in Effects, NLE, News, Post-Production, Research, TutorialsEditing Organazized has two great posts up with tips and tricks for getting the best-quality slowmo footage out of Final Cut Studio using Compressor. The first outlines the basic workflow, post #2 delves deeper into Compressor’s behavior at various retiming percentages and provides examples of the sort of results you can expect. In the footage for this example, best results degraded past 1/4 speed. At 25%, Compressor’s Optical Flow appears to preserve much more detail than what you can expect directly out of Final Cut Pro. Very informative articles.
Using the iPhone as a Storyboarding Tool
3 Comments Published by Matthew Jeppsen March 17th, 2008 in DIY, News, Production, Research, Tutorials Kenn Bell has a post up that talks about how he used the iPhone to storyboard a recent music video shoot. His technique is quick and looks to be very effective…take digital images while location scouting, throw together a quick iMovie video slideshow, and use the video on-set with the iPhone.
“Basically, we’d arrive at a location, I’d play the movie and let everyone, including Baby Jay, see what shots and looks I was interested in. It only took a minute and everyone was on the same page. I can’t stress enough how much time I saved! The three days went incredibly smooth and I really believe it was because the movie on my iPhone. It actually got everyone excited to see how cool the music video would look and I gained a great deal of trust from it.”
This would also be a good time to check out Kenn’s interview on the Digital Production Buzz podcast.
MPAA Releases 2007 Stats, Useful For Indies?
0 Comments Published by Matthew Jeppsen March 10th, 2008 in News, Off Topic, Research The Motion Picture Association of America released it’s “2007 U.S. Theatrical Market Statistics Report” which indicates record-level domestic and worldwide box office receipts. Filmlinker suggests that the data can be used by independent filmmakers to market their own projects:
“So why would an indie filmmaker care about this report? Well, beyond having a positive financial result from the medium that you work in - you can use those stats for your business plan. When pitching your project to potential financiers, it is always good to present a positive outlook in the industry that seeks investment. It’s arguably more difficult to convince someone to invest in your low budget film if the overall marketplace is on a decline.”
I noted that the average cost to make and market a major MPAA member film has risen about 6 million dollars over 2006’s $100.3 million level. Ticket prices have also risen, about 5% over 2006. The total number of films released has not changed significantly in the past year. Read the whole enchilada here (PDF), and compare to 2006’s report here (PDF). Another opinion on this new data comes via Norman Hollyn in an article entitled The Dismal Future of the Film Business.
Sony Z1U Equivalent Zoom Percentage Scale on the FX1
2 Comments Published by Matthew Jeppsen February 25th, 2008 in Cameras, FreshDV, Lenses, News, Research
The Sony HVR-Z1U and HDR-FX1 HDV cameras are basically an identical camera with the exception of a few key features. They are built on the same 3-CCD system, tape transport, and 4.5mm to 54mm lens (32.5mm to 390mm equivalent 35mm FOV). Z1U is the “pro” model and adds XLR audio, a 50Hz mode, and a number of additional menu settings and firmware-related tools (addl. Cine gammas, etc). For a complete breakdown of the two models, check this chart.
The point of this post is not to address the featureset of two HDV cameras that are getting somewhat long in the tooth, it is to talk about something that I haven’t found anywhere online before. One of the differences between the two cameras is the fact that the Z1U shows a numeric zoom scale on the display. With the lens at full wide it displays Z00, shows Z50 at about half zoom, and Z99 at full telephoto. In contrast, the FX1 simply displays a visual zoom scale indicator on screen. The only way to accurately return to a certain focal length is to use the physical zoom ring, which has a limited scale of mm markings on it. This scale matches the markings on the Z1U’s ring, which can be correlated to the internal numerical percentage scale. In recent testing it became necessary to determine what that correlation was, so without further ado here are the equivalent Z-numbers that relate to the Z1U’s zoom ring markings (and therefore also correlate to the markings on the FX1).

ProLost on Digital Cinema Dynamic Range
0 Comments Published by Matthew Jeppsen February 23rd, 2008 in Cameras, Formats, News, Research Stu Maschwitz has a in-depth post up where he talks about the latitude of current Digital Cinema cameras, and how the Rec709 colorspace (i.e. video) handles highlights vs film’s highlight handling. Where it gets sticky is how a clipped highlight in video maps to the highlights on film. If you are shooting with the Red One or another such camera and wish to output to film at some point, this is a must-read. Short on time? Read the compact summary. Here’s an excerpt:
“Shooting with RED One and monitoring Rec709, if you put 18% gray at 45% IRE, you’ll capture 2 stops over 18% gray, plus some headroom.
Want to match Panalog? Underexpose by 3 stops for 5 stops over 18% gray, plus headroom.”
For more experiences with the Red One from the field, read this Studio Daily article on the production of 3 Days Gone. Two interesting notes…they used a P2 recorder on set to capture and review dailies, and ProRes proxies of the 4K footage for editing.
ProRes Codec vs Uncompressed for SD Finishing
0 Comments Published by Matthew Jeppsen February 20th, 2008 in Formats, News, Research
Via Scott Simmons comes a link to one finishing company’s comparison test of Apple ProRes SD codec vs Uncompressed. This comparison was done on Standard Definition footage.
“When playing at speed, 1st Generation 10bit is indistinguishable from 3rd Generation ProResSD. I can’t see the edit…When paused on identical frames and quickly toggling between 1st generation Uncompressed and the 3rd generation ProResSD - levels and chroma are rock solid steady, but there is a oh-so-slight softening of the image. It’s slight enough that most my clients won’t be able to see it. Heck, I barely see it.ProsRes SD is an impressive codec. While only doubling the storage space of DV it gives 98% of the quality of Uncompressed. Good enough for finishing purposes? Yes. I would not use it for heavy compositing where every drop of detail is essential. Unlike the HD variant, which I’ve heard is rock-solid through (at least) 10 generations, the SD variant’s ‘lossy-ness’ does exist after 3 generations.”
XDCAM EX1 Hands-On - Camera Body and Controls Layout

XDCAM EX1 Hands-On - Depth of Field Examples
5 Comments Published by Matthew Jeppsen January 13th, 2008 in Cameras, Formats, FreshDV, News, ResearchThis article is part of a series of tests FreshDV conducted with the Sony XDCAM PMW-EX1. Thanks to Miami rental house and Sony dealer Midtown Video for providing a XDCAM EX camera. And thanks to DSC Labs for providing test chart patterns. You can read more about ours and others experiences with this camera here.
The Sony XDCAM PMW-EX1 is equipped with three half-inch CMOS image sensors, which not only perform well in low light but also deliver surprising depth-of-field. The EX’s Fujinon fully-manual lens can be adjusted down to f/1.9 and sustains that aperture throughout the entire range of the zoom. Bear in mind that shallow DOF is either a blessing or a curse, depending on what you wish to accomplish. For dramatic filmmaking, it can be a very effective tool at drawing focus to specific areas of the frame and de-cluttering backgrounds. Your focus puller may have to work hard, but the results can be brilliant. But for fast action and sports applications shallow DOF can be a curse. This footage from the EX1 shows exactly how shallow that DOF can be. For a very detailed explanation on the mechanics of DOF, watch this tutorial.

After shooting with the XDCAM EX1 for a few days and reviewing gigs of footage, Kendal and I have a lot to talk about. This audio podcast is a discussion about my personal experiences and tests with the Sony XDCAM PMW-EX1 camcorder. We open with a discussion about the evolution of shooters and how they tend to seek upgrades as they evolve in their craft and hit the ceilings and limitations of their gear. We then cover the EX1’s ergonomics and layout, menus and image control, lens and handling, the SxS workflow with FCP, transfer software and metadata, codec and compression (and how it fares against DVCPRO HD in initial comparisons), and finally CMOS sensors and all the good and bad that comes with this variety of imager.

XDCAM EX1 Hands-On - Night Footage Compression Examples
2 Comments Published by Matthew Jeppsen January 8th, 2008 in Cameras, Formats, FreshDV, News, ResearchThis article is part of a series of tests FreshDV conducted with the Sony XDCAM PMW-EX1.

One of the areas that the new Sony XDCAM PMW-EX1 really excels is in native light sensitivity. Night shooting with the EX is relatively simple, as the camera seems to find illumination and color saturation in even the darkest of scenes. Here are a few examples of night footage shot with the EX1, including a 60p overcranked shot. I have included a half-resolution H.264 version to show the context of the “full scene.” Each H.264 version is paired with a clip excerpt that has been preserved in it’s native XDCAM format. This gives you a short native-format full-resolution clip that you can drop in your editing software of choice and tweak, push, destroy, whatever. The only compression difference between these full-rez excerpts and what came directly off the camera is the addition of a text overlay to document camera settings. I have confirmed this by overlaying them over the source clips with a composite difference mode applied. So here’s a chance to analyze how the XDCAM SP and HQ codec performs at night in both slow and fast motion scenes. Note how the vertical lines in closeups of the overcranked shot seem to distort/lean…we’ll have more on the EX’s vertical skew in a article coming soon.

XDCAM EX1 Hands-On - Gamma and Color Matrix Presets
10 Comments Published by Matthew Jeppsen January 7th, 2008 in Cameras, FreshDV, News, Research, TutorialsThis article is part of a series of tests FreshDV conducted with the Sony XDCAM PMW-EX1. Thanks to Miami rental house and Sony dealer Midtown Video for providing a XDCAM EX camera. And thanks to DSC Labs for providing test chart patterns. You can read more about ours and others experiences with this camera here.
For this color reproduction comparison the XDCAM EX was shot in a studio environment using a DSC Labs ChromaDuMonde chart. The test pattern was evenly lit at 45-degree angles by two soft light sources, aperture on the EX1 was adjusted on each shot to ensure the center gray chips were exposed at 50%. Picture Profile Matrix and Gamma presets were shot individually, and then mixed in typical configurations (Cinema Matrix + Cine1 Gamma, etc). All footage was shot at 1080/24p HQ-mode. Other Picture Profile settings like Black levels and Detail enhancement were at 0 or factory defaults. The following 40MB zip archive contains 16 full-resolution uncompressed TIF frames exported directly from the FCP 6.0.2 timeline.
