is a constraint of the H.264 codec specified by Apple to ensure ease of consumer video editing.
It provides a square-pixel 16:9 image format of 960 horizontal by 540 vertical pixels, with progressive scanning at 30 frames per second and can be identified as the format "540p30". These parameters are one-half the spatial resolution of 1080p in each direction, one-quarter the total number of pixels. iFrame has 1.5 times the number of pixels in standard definition 4:3 720×480 CCIR 601 NTSC video. However, its progressive scanning increases the approximate perceived resolution advantage over 480i to roughly a factor of 2.
The 30 fps frame rate used for iFrame may result in increased "judder" with moving images, when compared to the nominal frame rate of 60 fields per second (30 fps interlaced with even and odd lines) used in North America for professional video.
The audio is AAC-encoded.
The video sub-sampling, bit-depth, and the video, audio and aggregate bit-rates are not yet publicly known.
At introduction in October of 2009, two camera models from Sanyo supported the format.
The most interesting about the iMovie update that dropped yesterday is that "improves compatibility" with camcorders using the iFrame video format. The iFrame video format, you say? Why yes, it's a new video format from Apple.
iFrame's based on industry-standard codecs H.264 and AAC, but it's got a standard res of 960x540 and it's designed by Apple "to speed up importing and editing by keeping the content in its native recorded format while editing."
Currently, the only two camcorders using iFrame are the Sanyo VPC-HD2000A and VPC-FH1A. The question is what other cameras are gonna be using it and how much of a real standard iFrame's going to be. We all know how much Apple loves setting standards.
SANYO has released its two new high-end digital camcorders – SANYO VPC-HD2000A (vertical form factor) and VPC-FH1A (horizontal), which the company claims as the world’s first camcorders that support new iFrame video format – the next generation computer-friendly video format (designed by Apple) which allows users to dramatically speed up the process of importing, editing and sharing movies by keeping the content in its native recorded format while editing, aiming to enhance your video editing and sharing experience.
Features Of SANYO VPC-HD2000A And SANYO VPC-FH1A:
3-inch wide LCD Monitor (SANYO FH1A); 2.7-inch wide screen display (SANYO HD2000A)
10x optical zoom for photos and 16x advanced zoom (includes more area than standard zooming) for video
Digital Image Stabilizer for video and stills shot
iFrame video format H.264 960 x 540 pixels (30 frames per second)

Three-Dimensional Noise Reduction (3D-DNR) technology offers a significant improvement in video clarity by reducing random signal noise
Super fast start-up and recording in as little as 1.7 seconds
Built-in SD/SDHC memory card slot
“SANYO is proud to be the first manufacturer to offer camcorders that are compatible with the iFrame video format. This format offers a major breakthrough in reducing the time it takes for consumers to import, edit and share high quality video,” said Tom Van Voy, General Manager for Consumer Products Group at SANYO North America. “In addition to this new video format, our Dual Cameras also offer the ability to shoot 8-Megapixel photos as well as a number of video modes, including Full HD 1080P/60fps, making them the perfect choice for sharing high quality movies with family and friends, for video bloggers or budding videographers.”
The new compact SANYO VPC-HD2000A and VPC-FH1A camcorders that offered in black color are now available for around $600 and $500, respectively.
