The Sony α NEX-5 is a digital camera launched on 11 May 2010. It is a mirrorless interchangeable lens camera with the body size of a larger model fairly compact point-and-shoot camera with a larger sensor size ( APS-C ) comparable to that of some digital single-lens reflex cameras . Its major competitors in the market are the cameras based on the micro 4/3 standard created by Panasonic and Olympus , and a few low end Canon , Nikon , and even Sony α DSLRs. The NEX-5 shoots 14.2 megapixel stills and has a 7 frame/s continuous shotmode. It has the capability to shoot 1920×1080i at 60 frame/s in AVCHD or 1440×1080p at 30 frame/s in MPEG4 . The NEX-5 was replaced by the 16 megapixel NEX-5N in August 2011.
46-768: The α NEX-5 has features found in SLR cameras but also some that are normally found in point and shoots. The body of the α NEX-5 is made of magnesium alloy that separates the NEX-5 from the less expensive polymer NEX-3 . Also different from the NEX-3 is video quality. The NEX-5 can shoot in AVCHD 1080/60i HD. There is a 7 frame/s continuous shot mode, with autofocus disabled after the first frame. The APS-C sized sensor has an ISO sensitivity up to 12,800. The camera software has special features like twilight mode and sweep panorama. The latter lets

Secure Digital memory cards can be used in Sony XDCAM EX camcorders via the MEAD-SD01 adapter. JVC camcorders that record in XDCAM EX format use Secure Digital memory cards natively. XQD memory cards can be used in Sony XDCAM EX camcorders via
138-557: A Blu-ray Disc player without re-encoding. Interlaced video had been originally designed for watching on a cathode-ray tube television set. Material recorded for interlaced presentation may exhibit combing or ghosting when it is rescaled , filmed out or watched on a computer or another progressive-scan device without proper deinterlacing . Some AVCHD 1080i camcorders can capture progressive video and record it within interlaced stream borrowing techniques from television industry. In particular, Progressive segmented frame (PsF)
184-469: A Blu-ray Disc video title does not require re-encoding of AVCHD audio and video streams. The resultant disc plays in any Blu-ray Disc player, including those that do not explicitly support AVCHD. Many software vendors support AVCHD mastering. In particular: Although AVCHD shares many format similarities with Blu-ray Disc, it is not part of the Blu-ray Disc specification. Consequently, AVCHD-playback
230-788: A DVD. Such AVCHD discs are incompatible with regular DVD-Video players, but play in many Blu-ray Disc players. A conventional single-layer 12 cm DVD can store 35 minutes of video recorded at the maximum bitrate the AVCHD specification allows for DVD media—18 Mbit/s. A hard disk drive was added as an optional recording medium to AVCHD specification shortly after the new video standard had been announced. Presently, capacity of built-in HDDs ranges from 30 GB to 240 GB. Pros: Cons: Many AVCHD camcorders employ Secure Digital or " Memory Stick " memory cards as removable recording media. Solid-state memory cards offer rewritable storage in
276-812: A compact form factor with no moving parts. Panasonic and Sony chose removable flash memory as the sole type of recording media in their professional AVCHD lineups, specifically AVCCAM and NXCAM. Until 2010, Sony insisted on usage of its own memory card format - Memory Stick. Since 2010, Sony has allowed using both Memory Stick as well as Secure Digital cards in its consumer and professional camcorders. Panasonic as well as other manufacturers of AVCHD camcorders use Secure Digital cards as removable flash media. Most models accept Secure Digital High Capacity cards (SDHC), while some models are also compatible with Secure Digital Extended Capacity (SDXC) cards, which offer higher transfer speed and capacity. Pros: Cons: Some AVCHD camcorders come with built-in solid-state memory either as
322-579: A computer by connecting the camcorder via the USB connection. Removable media like SDHC and Memory Stick cards or DVDs can be read on a computer directly. Copying files from an AVCHD camcorder or from removable media can be performed faster than from a tape-based camcorder, because the transfer speed is not limited by realtime playback. Just as editing DVCPRO HD and HDV video once demanded an expensive high-end computer, AVCHD editing software requires powerful machines. Compared to HDV, AVCHD requires 2-4 times
368-533: A format acceptable for professional use. Both Panasonic and Sony released the first consumer AVCHD camcorders in spring of 2007. Panasonic released the first AVCHD camcorder aimed at the professional market in 2008, though it was nothing more than the (by then discontinued) FLASH card consumer model rebadged with a different model number. In 2011 the AVCHD specification was amended to include 1080-line 50-frame/s and 60-frame/s modes (AVCHD Progressive) and stereoscopic video (AVCHD 3D). The new video modes require double
414-531: A per unit sold basis ). Another difference is location of the BDMV directory, which contains media files. On a DVD-based camcorder the BDMV directory is placed at the root level, as on the Blu-ray Disc. On the HDD-based Canon HG10 camcorder the BDMV directory is located in the AVCHD directory, which is placed at the root level. Solid-state Panasonic and Canon camcorders nest the AVCHD directory inside
460-661: A sole media, or in addition to other media. Pros: Cons: Panasonic and Sony developed several brand names for their professional as well as simplified versions of AVCHD. AVCHD Lite is a subset of AVCHD format announced in January 2009, which is limited to 720p60, 720p50 and 720p24 and does not employ Multiview Video Coding . AVCHD Lite cameras duplicate each frame of 25fps/30fps video acquired by camera sensor, producing 720p50/720p60 bitstream compliant with AVCHD and Blu-ray Disc specifications. As of 2013, AVCHD Lite seems to have been all but replaced with other formats. For example,
506-421: A traditional videotape -based workflow. These decks can also serve as random access computer hard drives for easy import of the video data files into non-linear editing systems (NLE) via FireWire ( IEEE 1394 ) and Ethernet . In September 2008, JVC announced its alliance with Sony to support the XDCAM EX format. In August 2009, Convergent Design began shipping the nanoFlash Portable Recorder, which uses

#1732787536006552-798: A variety of ways: A DVD disc with AVCHD high-definition video recorded on it is sometimes called an AVCHD disc . AVCHD discs cannot be played in a standard DVD player, but can be played in many Blu-ray Disc players. Smooth playback is not guaranteed if overall data rate exceeds 18 Mbit/s. It is possible to create simple menus similar to menus used for DVD-video discs. AVCHD content can also be recorded on SDHC cards and played by many television sets, Blu-ray Disc players and media consoles. The AVCHD specification does not officially support Blu-ray Disc media, though some software packages allow authoring AVCHD content on Blu-ray Discs. For better compatibility with Blu-ray Disc players AVCHD video can be authored on Blu-ray Disc media as Blu-ray Disc video. Authoring
598-493: A very limited support. The Professional Disc was chosen by Sony as its medium for professional non-linear video acquisition for a number of reasons, outlined in their white-paper Why Sony Adopted Professional Disc . This disc is similar to Blu-ray Disc and holds either 23 GB of data (PFD23, single-layer, rewritable), 50 GB (PFD50, dual-layer, rewritable), 100 GB (PFD100TLA, triple-layer, rewritable) or 128 GB (PFD128QLW, quad-layer, write-once). Essentially,
644-531: A wide range 18–200 mm E-mount lens. With the post-November 2010 firmware version 3 installed, and by using the (roughly US$ 200) Sony LA-EA1 adapter, the NEX series of cameras is able to electronically control the aperture and autofocus of Sony SSM/SAM A-mount lenses, and control the aperture of the other Sony/Minolta A-mount lenses with manual focus only. The (roughly US$ 400) Sony LA-EA2 adapter also supports autofocus with screw-drive A-mount lenses, firmware version 5
690-593: Is a solid-state memory card implemented as an ExpressCard module. The first camera to use this media was the Sony PMW-EX1 professional video camera . In December 2009, Sony introduced the more affordable SxS-1. This unit is designed to have the same performance as the SxS Pro card however its life expectancy is shorter at an estimated 5 years of life when used every day to the card's full capacity. In early 2013, Sony has introduced SxS Pro+ cards. These have

782-588: Is a file-based format for the digital recording and playback of high-definition video . It is H.264 and Dolby AC-3 packaged into the MPEG transport stream , with a set of constraints designed around camcorders. Developed jointly by Sony and Panasonic , the format was introduced in 2006 primarily for use in high definition consumer camcorders . Related specifications include the professional variants AVCCAM and NXCAM . Favorable comparisons of AVCHD against HDV and XDCAM EX solidified perception of AVCHD as
828-476: Is comparable to Digital Betacam MPEG IMX is not supported in the XDCAM ;EX product line. MPEG HD is used in all product lines except for XDCAM SD. This format supports multiple frame sizes, frame rates, scanning types and quality modes. Depending on product line or a particular model, not all modes of this format may be available. MPEG HD422 doubles the chroma horizontal resolution compared to
874-480: Is compatible with most editing systems. Some camcorders that allow DVCAM recording can record progressive-scan video. MPEG IMX allows recording in standard definition, using MPEG-2 encoding at data rate of 30, 40 or 50 megabits per second. Unlike most other MPEG-2 implementations, IMX uses intraframe compression with each frame having the same exact size in bytes to simplify recording onto video tape. Sony claims that at 50 Mbit/s it offers visual quality that
920-480: Is either repeated twice or a special flag in the video stream instructs a decoder to play every frame twice to adhere to output rate of 50 or 60 frames/s. Many of the digital compact cameras made by Panasonic, such as the DMC-ZS3/DMC-TZ7, DMC-FT1, DMC-FZ35/DMC-FZ38, and DMC-ZS-7/TZ-10 offer 720p video recording with effective frame rate of 25 or 30 frames/s in a format called AVCHD Lite (see below). Until
966-430: Is not universally supported across Blu-ray Disc players. Blu-ray Disc players with "AVCHD" logo play AVCHD discs authored either on 8 cm or 12 cm DVDs. Players without such a logo are not guaranteed to play AVCHD discs. XDCAM XDCAM is a series of products for digital recording using random access solid-state memory media, introduced by Sony in 2003. Four different product lines –

#17327875360061012-446: Is required for this adapter. Other third-party mechanical tube adapters are also available. These adapters enable the use of Canon FD-mount, Canon EF-mount (without aperture control), Contax G, M42 screw mount, Konica Hexanon AR-mount, Minolta SR-mount (MC/MD), Leica M and screw mount, Nikon F-mount (non-G), Pentax K-mount (non-DA), Olympus OM mount, T2 screw mount and Minolta/Konica Minolta/Sony A-mount lenses. The E-mount flange register
1058-440: Is similar to DVD-video, allowing access to individual videos from a common intro screen. Slide shows are prepared from a sequence of AVC still frames, and can be accompanied by a background audio track. Subtitles are used in some camcorders to timestamp the recordings. Audio, video, subtitle, and ancillary streams are multiplexed into an MPEG transport stream and stored on media as binary files. Usually, memory cards and HDDs use
1104-574: Is so short that it is possible to mount 45 mm or longer-focal-length non-focusing enlarging lenses on the NEX body, with the use of an intermediate focusing helicoid behind them. Certain third-party mechanical adapters also provide circular control rings that provide some mechanical control of the aperture of Nikon G, Pentax DA and Canon EF lenses, as these do not have a mechanical aperture control ring on their lens barrels. The incomplete model number of NEX-3/NEX-5 series may include letter(s) at end. The definitions are: For example, NEX-5CK/B 50i
1150-421: Is supported. Audio data rate can range from 64 kbit/s to 640 kbit/s. In practice, data rates of 256 kbit/s and 384 kbit/s have been observed. Some professional models allow recording uncompressed linear PCM audio . AVCHD specification allows using recordable DVDs, memory cards, non-removable solid-state memory and hard disk drives as recording media. When the AVCHD standard was first announced, recordable DVD
1196-673: Is used for proxy video. Audio is recorded in uncompressed PCM form for all formats except proxy video, which uses A-law compression. Equipment that uses Professional Disc as well as XDCAM 4:2:2 on SxS cards as recording media employs MXF container to store digital audio / digital video streams. Tapeless camcorders that record onto solid-state memory cards, use MP4 container for high definition audio/video, and DV-AVI container for DV video. JVC camcorders that use XDCAM EX recording format, are also capable of recording into QuickTime container besides using MP4 container. DVCAM uses standard DV encoding, which runs at 25 Mbit/s, and
1242-599: Is used in the shoulder-mount Panasonic HDC-MDH1, as well as on its North American AG-AC7 cousin. A successor model – the AG-AC8, is also capable of recording in AVCHD-SD mode. Several models from JVC like the consumer camcorders GZ-HM650, GZ-HM670 and GZ-HM690 as well as the professional camcorder JVC GY-HM70 can record AVCHD-SD video. AVCHD-SD is not compatible with consumer DVD players, because it employs AVC video encoding instead of MPEG-2 Part 2. AVCHD-SD can be played on
1288-453: Is utilized in some Panasonic (25p Digital Cinema), Canon (PF25, PF30) and Sony camcorders. The 2:3 pulldown technique is used in some 60 Hz versions of Canon (PF24) and Panasonic (24p Digital Cinema) camcorders for recording 24-frame/s progressive video. Most editing tools treat progressive video recorded within an interlaced stream as interlaced, though some editing systems and most standalone Blu-ray Disc players are capable of recognizing
1334-545: The FAT file system, while optical discs employ UDF or ISO 9660 . At the file system level, the structure of AVCHD is derived from the Blu-ray Disc specification, but is not identical to it. In particular, it uses legacy " 8.3 " file naming convention, while Blu-ray Discs utilize long filenames (this may be caused by the fact that FAT implementations utilizing long file names are patented by Microsoft and are licensed on
1380-552: The PRIVATE directory. Following a standard agreed upon by many still camera manufacturers, solid-state camcorders have a root-level DCIM directory for still images. AVCHD is compatible with the Blu-ray format and can be authored without re-encoding on Blu-rays or DVDs, though not all Blu-ray Disc players are compatible with AVCHD video authored on DVD media, a format known as AVCHD disc . AVCHD recordings can be transferred to
1426-586: The Panasonic DMC FZ-200 offers AVCHD Progressive recording mode (50fps/60fps acquisition and stream rate) as well as MP4 mode (25fps/30fps acquisition and stream rate). Formerly known as "AVCHD with professional features," AVCCAM is the name of professional AVCHD camcorders from Panasonic's Broadcast division. Some of these professional features listed in early Panasonic advertising materials included 1/3-inch progressive 3CCD sensor, XLR microphone input, solid-state media and capability of recording at

1472-503: The Professional Disc format was deemed to be a suitable, cost effective and easy step forward. The discs are reliable and robust, suitable for field work (something which has previously been a problem with many disc-based systems). Additionally, the cost of media is comparable to existing professional formats. In 2008, Sony introduced a new recording medium to their XDCAM range – SxS Pro (pronounced "S-by-S"). It
1518-584: The Sony XDCAM HD422 codec. In November 2012, VITEC began shipping the FS-T2001 Portable Recorder, which uses Sony XDCAM HD422 and XDCAM HD codec. The XDCAM format uses multiple video compression methods and media container formats. Video is recorded with DV , MPEG-2 Part 2 or MPEG-4 compression schemes. DV is used for standard-definition video , MPEG-2 is used both for standard and high definition video, while MPEG-4
1564-567: The XDCAM SD, XDCAM HD, XDCAM EX and XDCAM HD422 – differ in types of encoder used, frame size, container type and in recording media. None of the later products have made earlier product lines obsolete. Sony maintains that different formats within XDCAM family have been designed to meet different applications and budget constraints. The XDCAM range includes cameras and decks which act as drop-in replacements for traditional VTRs allowing XDCAM discs to be used within
1610-420: The advent of AVCHD Progressive mode, native progressive-scan video for 1080-line resolution had been available only in 24 frames/s variant. In 2010, Panasonic introduced a new lineup of consumer AVCHD camcorders with 1080-line 50p/60p progressive-scan mode (frame rate depending on region). Panasonic advised that not all players that support AVCHD playback could play 1080-line 50p/60p video. In 2011, this mode
1656-449: The bitrate to 85 Mbit/s. This format has never become widely used and a very limited set of devices support it. Proxy AV is used to record low resolution proxy videos. This format employs MPEG-4 video encoding at 1.5 Mbit/s ( CIF resolution) with 64 kbit/s (8 kHz A-law , ISDN-quality) for each audio channel. ^ 1 720p @ 19 Mbit/s is offered by JVC and is equivalent to HDV 720p XDCAM-SHD422 has
1702-473: The camcorder is "shaped for Pro-Style shooting in Full-HD" with shoulder-mount type body being "preferred by professionals". NXCAM is the name of Sony's professional video lineup employing the AVCHD format. NXCAM camcorders offer 1080i, 1080p and 720p recording modes. Unlike AVCCAM, not all NXCAM camcorders offer film-like frame rates—24p, 25p, 30p—in 720p mode. Recorded AVCHD video can be played back in
1748-609: The data rate of previous modes. AVCHD and its logo are trademarks of Sony and Panasonic. For video compression, AVCHD uses the H.264/MPEG-4 AVC standard, supporting a variety of standard, high definition, and stereoscopic (3D) video resolutions. For audio compression, it supports both Dolby AC-3 (Dolby Digital) and uncompressed linear PCM audio. Stereo and multichannel surround (5.1) are both supported. Aside from recorded audio and video, AVCHD includes many user-friendly features to improve media presentation: menu navigation, simple slide shows and subtitles. The menu navigation system
1794-537: The maximum AVCHD bitrate – 24 Mbit/s. The aforementioned features are not exclusive to AVCCAM. Moreover, some of these features like CCD sensor technology have been dropped by Panasonic, while 24 Mbit/s recording rate is widely available from rival manufacturers even on consumer models. Panasonic uses "AVCHD Pro" moniker to describe camcorders like the HDC-MDH1, which combines consumer internal parts and controls with shoulder-mount type body. Panasonic touts that

The NEX-5 along with its sister, the NEX-3, and also the Sony Handycam NEX-VG10 use a new lens mount system developed by Sony for NEX series and known as the Sony E-mount . Initially, there were three available lenses: an all-purpose 18–55 mm lens, an ultra wide pancake 16 mm lens, and
1886-490: The previous generations of high-definition video XDCAM formats. To accommodate the improved chroma detail, video bitrate has been increased to 50 Mbit/s. This format is used only in XDCAM HD422 products. MPEG SHD422 XDCAM-SHD422 stands for "Super HD" and has been introduced later on to preserve more details. It maintains the 4:2:2 planar chroma sampling as well as the same resolution of MPEG HD422, but it increases

1932-406: The processing power for realtime playback, placing a greater burden on the computer's CPU and graphics card. Improvements in multi-core computing and graphics processor acceleration bring AVCHD playback to mainstream desktops and laptops. AVCHD supports a variety of video resolutions and scanning methods, which was further extended with the 2011 amendment of the specification. The licensing body of
1978-442: The pulldown pattern to recover the original frames using the process known as inverse telecine . Since the very beginning, the AVCHD specification had supported 720-line progressive recording mode at frame rates of 24 and 60 frames/s for 60 Hz models and 50 frames/s for 50 Hz models. Frame rates of 25 frames/s and 30 frames/s are not directly available in 720p mode, but can be simulated with frame repeating, when every frame
2024-439: The specification defines a variety of labels for products compliant with specific features. Most AVCHD camcorders support only a handful of the video and audio formats allowed in the AVCHD standard. AVCHD supports both standard definition (AVCHD-SD) and high definition (AVCHD 1080i ) interlaced video. AVCHD 1080i is available on most AVCHD camcorders. For some models this is the only recording mode offered. AVCHD-SD
2070-624: Was officially included into the AVCHD specification as part of 2.0 addendum, and has been called AVCHD Progressive. This mode uses the same AVCHD folder structure and container files for storing video, with the maximum bitrate of 28 Mbit/s. In 2011, Sony introduced consumer and professional AVCHD models capable of AVCHD Progressive recording. In 2012 JVC announced the GY-HMQ10 model, which also can record AVCHD Progressive video. Most AVCHD camcorders record audio using Dolby Digital (AC-3) compression scheme. Stereo and multichannel audio
2116-638: Was the only recording medium. To reduce camcorder size, manufacturers opted for an 8 cm disc, sometimes called miniDVD . Recording capacity of an 8 cm disc ranges from 1.4 GB for a single-sided single layer disc to 5.2 GB for a double-sided double layer disc. Pros: Cons: As the capacity of memory cards grew and their price dropped, DVDs use for recordable media declined. No DVD-based AVCHD camcorders have been produced since 2008. While DVDs are no longer used for acquisition, they remain popular as distribution media. Many authoring programs offer "AVCHD" profile for recording high definition video on
