AJA Video HD10AVA SD/HD Analog Composite or Component Video and 4-Channel Analog Audio to SD/HD-SDI with Embedded Audio
The
AJA HD10AVA is a miniature, high-quality, audio/video, HD/SD A/D converter. The HD10AVA automatically detects the video input format and embeds the audio inputs in the SDI/HD-SDI outputs. Perfect for HDV cameras and decks with an analog Component HD and Analog Audio output for conversion to HD-SDI with embedded audio. The HD10AVA uses a breakout cable for audio/video inputs and provides 3 SDI-HD-SDI on BNCs (breakout cable included).

Benefits of a Dual Rate Converter
The HD10AVA is a dual rate converter which means that it can convert analog SD to SD-SDI or analog HD to HD-SDI. An obvious benefit of the converter is that it can take analog SD video and analog audio outputs, such as those from a Betacam SP device, and convert these analog outputs to an SD-SDI signal with embedded audio.
A further benefit of the HD10AVA is using it for conversion of HDV signals. Cost effective HDV cameras can record a compressed Long GOP MPEG2 HD signal on inexpensive MiniDV tapes. What is often not advantageous about the HDV cameras and decks in a professional environment is their lack of HD-SDI connectivity. However, the cameras almost always have an analog component HD output. The AJA
HD10AVA converter can be used to convert component analog HD video and analog audio outputs of HDV devices to an HD-SDI signal with embedded audio. This offers advantages over IEEE1394 connectivity for post production and unique output capabilities from the camera on set.
Why Choose HD-SDI over IEEE1394 FireWire?
While the HDV cameras and decks always support a IEEE1394 (aka FireWire connection) not all non-linear editing systems can accept the HDV signal through such a connection. If a non-linear editing system can accept the IEEE1394 signal, the footage can be
ingested in its native, highly compressed state. While this seems like a simple solution for post-production, it means that the footage stays in the compressed Long GOP MPEG2 structure in which it was recorded and this structure can be incredibly processor intensive for most non-linear computers to negotiate. The first benefit when ingesting HDV material through an analog to HD-SDI conversion versus ingesting via IEEE1394 for post production is that the structure of the signal will be brought in as an I-Frame based structure common to the non-linear editor as opposed to the HDV's native Long GOP MPEG2 structure, which may prove more difficult to edit.
Additionally, what if the post-production process demands that the HDV acquisition be delivered as a finished product on HD formats such as Panasonic D5, DVCProHD or Sony HDCam? Working with the compressed HDV material would be akin to working
with DV natively for SD broadcast; less than ideal. Certain post-production processes would be better performed in a 10 bit (or even 8 bit) 4:2:2 color space than in the 8 bit 4:2:0 color space that is the domain of the compressed HDV format. If the non-linear
editing system could ingest via HD-SDI using the AJA HD10AVA converter's HD-SDI output, then digitizing to an uncompressed codec might be a better choice for tasks like color correction and compositing.
Why Choose HD-SDI over Component Analog HD Video and Analog Audio?
As already mentioned, most HDV cameras have a component analog HD output. The advantages of using HD-SDI over analog HD are threefold. HD-SDI can be run for much further distances than component analog video. HD-SDI, as output from the AJA HD10AVA, can support video and embedded audio, so cabling is minimized - one cable can carry the video and audio signal. And finally, if recording to an HD deck, HD-SDI is the standard connection for input, not component analog HD.
