Deinterlace #Canon HV20/HV30/HV40 #HDV 60i #Video to MOV 24p for FCE/FCP/Adobe Premiere

Canon HV20/HV30/HV40 is a great choice for HD-happy amateurs, but its low-light performance could have been better. HV20 and HV30 wrap in 60i. Some confusion on if HV40 does/did the same. When it was launched it was claimed to be different, but in practice is it? It’s still a single CMOS sensor, and still HDV. And still looks a bit washed out without color grading IMO.
HDV stores the video as 1440 horizontal pixels by 1080 vertical pixels. FULL HD is typically 1920 horizontal and 1080 vertical. Both are 16:9 aspect rations. HDV is an mpeg2 codec and FULL HD / AVCHD / AVC1 is an h264 codec.

No matter what, if you have a Canon HV20/HV30/HV40 for shooting HDV 60i footages, you will have a problem of displaying the video with many interlaces. So before sharing your HDV footages with family, or before editing the HDV files with FCE/FCP/Adobe Premiere Pro/iMovie, you need deinterlace/convert Canon HV20/HV30/HV40 HDV (60i) files to HDV 1080p24 (*.mov) or HDV 720p24 (*.mov).

Aunsoft Video Converter for Mac as the recommended Canon HV20/HV30/HV40 HDV (60i) files to Apple HDV 1080p24 (*.mov) or HDV 720p24 (*.mov) Converter on Mac. It does not only allow you to trim and crop HDV footage, but also deinterlaces/merge HV20/HV30/HV40 HDV 1080i videos, convert 1080i to 1080p.

Below is the simple guide about how to deinterlace/convert Canon HV20/HV30/HV40 HDV (60i) files to Apple HDV 1080p24 (*.mov) or HDV 720p24 (*.mov) for FCE/FCP/Adobe Premiere Pro/iMovie. It also works for iMovie 8/9 and even 11.

Step 1. Download Canon HV20/HV30/HV40 HDV videos to Aunsoft Video Converter for Mac. Click the “Add” button to download 1080i .hdv files from camcorder to the application.

Step 2. Choose HDV 1080p/24 MOV or HDV 720p24 MOV output format.

Click the “Format” option, and navigate to FCP > HDV 1080p/24 (*.mov) or HDV 720p24 (*.mov) as output format. The Mac HV20/HV30/HV40 HDV to MOV converter will convert HV20/HV30/HV40 HDV files to MOV for FCE/FCP/Adobe Premiere Pro/iMovie.

Step 3. Deinterlace Canon HV20/HV30/HV40 HDV 60i video.

Select a clip on the file list, and the “Editor” button will be activated. Click the “Editor” button and go to the Effect tab to tick the checkbox for deinterlacing. The apply to all button is to deinterlace all the videos on current file list.

Step 4. Convert Canon HV20/HV30/HV40 HDV video to HDV 1080p/24 or 720p24 MOV for Mac.

Click the convert button under the preview window, the Mac Canon HV20/HV30/HV40 video converter will start the conversion and deinterlace Canon HDV 60i video to 24p MOV for fast editing in Final Cut Express, iMovie, and other Mac applications.

Tips: Pros and cons of MPEG-2 HDV vs H.264 AVCHD


Mpeg2 doesn’t require a lot of thinking by the computer. H264 does require quite a bit of decoding to render (or convert). Let’s call that speed. So mpeg2 is faster. But mpeg2 (HDV) isn’t as efficient and relatively wastes bits. With a minor trade off of having more bits (25Mpbs CBR) and fewer pixels to represent with those bits (1440×1080). If it were h264, it would be better. But since it’s not and h264 is more efficient, h264 (AVCHD) is generally considered better. Relatively anyway. They’re both compressed and lossy.

Excellent Low Light Performance
Many compact camcorders struggle in low light, producing grainy images. A super sensitive Exmor R CMOS sensor reduces image noise for clearer images. In conjunction with the powerful BIONZ processor you'll get great results in low light, ideal for corporate and event videography where light conditions cannot necessarily be controlled.
Steady Shooting without Additional Grip Equipment
Documentary and video diary productions are often shot handheld by non-professional camera operators. New Optical SteadyShot Active Mode delivers best-ever '3-way' camera shake correction at all zoom settings, even when you're walking along. In wide angle position, you'll enjoy up to ten times improved anti-shake performance, ideal for delivering watchable content in different shooting conditions.
Wide Angle G-Lens
Experience Sony's latest lens technology with the professional-quality G Lens. Engineered for superior optical performance, Sony G lenses deliver brilliant, accurate color reproduction and sharp, amazingly detailed images. In addition, the 29.8mm lens offers a very wide angle of view. The six-bladed iris offers superb shallow depth of field videography.
10x Optical / 120x Digital Zoom
10x optical zoom helps to bring the action close up from far away. In addition, Digital Zoom Interpolation means that digital zooming (up to 120x) is clearer, with less distortion than previous types of digital zoom.
Optical SteadyShot Image Stabilization with Active Mode
SteadyShot image stabilization with Active Mode represents the next step forward in Sony image stabilization technology. Active Mode improves on existing SteadyShot image stabilization by allowing the camera to compensate for greater degrees of camera shake and deliver a stunning level of image smoothness.
1/2.88" Back-Illuminated "Exmor R" CMOS Sensor
Experience low-light sensitivity with improved image clarity and drastically reduced grain with the back-illuminated "Exmor R" sensor. "Exmor R" technology captures footage with high resolution and high sensitivity, while the advanced Sony BIONZ Image Processor improves camera response time and screens out noise to help ensure that the signal from each pixel is as pure as possible.
BIONZ Image Processor
The BIONZ Image Processor works in conjunction with the Exmor CMOS sensor with ClearVid array for pristine imaging. The BIONZ Image Processor provides Data Noise Reduction, Fast Image processing, and Data compression. In addition, the BIONZ Image Processor enables Sony's Dynamic Range Optimizer for both video and still image capture. The higher processing speed also allows Dual Recording to capture still images while recording video footage.
Dynamic Range Optimizer
The D-Range (Dynamic Range) Optimizer function adjusts the exposure and contrast of an image to counter the effects of high-contrast shooting conditions, allowing better picture reproduction. The D-Range Optimizer suppresses "blackout" in dark areas such as shadows and "whiteout" in bright areas such as skies. As a result, the footage appears more natural.
1920 x 1080 Full High Definition AVCHD Recording
1920 x 1080i full HD resolution gives your production exceptional high-definition quality.
64GB Internal Flash Memory
The built-in 64GB embedded flash memory can record and store up to 6 hours of high definition video footage (HD FX mode at 24Mbps), or up to 48 hours of standard definition footage (SD HQ mode).
Media Card Slot
The camcorder accepts a wide range of removable media, including: Memory Stick Duo / Memory Stick PRO Duo / Memory Stick PRO-HG Duo media and SD/SDHC media.
3.5" Wide Xtra Fine TruBlack LCD Plus Viewfinder
TruBlack technology brings remarkably higher contrast and brightness to the camcorder's 3.5" Wide Xtra Fine TruBlack LCD display, delivering more natural, realistic colors and easier viewing in bright conditions by reducing glare. An adjustable 0.27" color viewfinder (201k) allows you to capture video and frame your shots with the LCD closed.
Assignable Dial
Get the most out of your camcorder with enhanced manual controls. The assignable dial allows for control of focus, exposure, white balance, iris, and shutter speed. Adjusting the iris lets you control depth of field, while shutter speed allows control of motion blur. There are a total of 6 settings available: Focus, Exposure, AE Shift, WB Shift, Iris control, and Shutter speed control.
Geotagging with Built-In GPS Receiver and NAVTEQ Maps
A built-in GPS receiver gives you the ability to view your current location on the LCD map display, as well as "tag" your shooting locations with GPS metadata. This metadata can be viewed using the Map Index function on the camcorder or once downloaded to your PC using the supplied PMB (Picture Motion Browser) software. Additionally, the receiver automatically adjusts your camcorder's clock to the proper time zone.
Dedicated Shotgun Microphone and Headphone Inputs
The HXR-MC50U offers a supplied professional shotgun microphone and mount which, coupled with the headphone input, allows acquisition and monitoring of location sound. (Headphones not supplied.)
Golf Shot
Building on the slow-motion capture capabilities of Smooth Slow Record on models such as the HVR-Z5 and Z7, Golf Shot captures a few seconds of motion as a sequence of up to 22 still images, which can be viewed/printed individually or as a composite "sequence shot" image, great for analyzing the nuances of a golf swing, tennis serve, and other fast action for sports science teaching and sports tutoring applications.
2x Faster Quick AF
With the improved autofocus (AF) system, Quick AF, the focusing speed is twice as fast compared to other Sony compact camcorders. Whether in bright daylight or in a dimly lit environment, Quick AF ensures fast, accurate, and consistent focus lock, enabling users to shoot in a wide range of scenes without missing any important moments. When shooting night scenes, conventional AF might struggle to focus, but thanks to the much improved AF algorithm in Quick AF, you can get that all-important shot.
Intelligent Auto (10 iAuto modes)
Intelligent Auto mode goes a step beyond traditional auto modes by analyzing your shot and then automatically selecting the appropriate settings from 10 distinct scene modes: Portrait Mode, Smile Shutter, Backlight Control, Scenery, Night Scenery Mode, High Sensitivity Mode, Macro Mode, Baby Mode, Tripod, and Low Light Mode--ideal for corporate or video diary applications where non-camera operators are shooting.
Film Roll Index
Film Roll Index helps you easily find desired clips. When using this feature, the camcorder previews the beginning of clips and can create clip indexes set at specified display intervals (3, 6, or 12 seconds and 1 or 5 minutes)
Direct Copy to External HDD without a PC
Store your content in a whole new way with the ability to copy content from your camcorder directly to an external hard disk drive (optional), all without a PC or Mac. Your camcorder can also access content stored on the external hard drive for playback on an HDMI monitor or consumer TV, allowing you to use the camcorder's handy playback features--great for viewing full HD rushes.
Smooth Slow Record
The Smooth Slow Record mode increases the frame rate from 50 frames per second (fps) to 200 fps, allowing you to capture 3 seconds of fast motion and play the video back in 12 seconds. This is a great tool for analyzing a golf swing or natural history applications.
12MP Digital Still Capture
12 megapixel still image capture lets you take stunning, high resolution digital photos while the Dual Record capability lets you capture 8.3MP still images while shooting high definition video--so you can capture still images without having to switch recording modes.
Sony PMB (Picture Motion Browser) Software
Sony Picture Motion Browser software offers a simple, intuitive way to transfer, sort, and view your video and still images on your compatible PC. In addition, multiple output options let you burn your content to DVD (optional), as well as being able to upload your rushes with just one click to popular video sharing sites.
