Voiceover recording in the timeline
The voiceover feature of Premiere Pro is supported to let you record audio directly in the timeline. It is based on ASIO driver
technology, which provides low latency. ASIO is a trademark and software of Steinberg Media Technologies GmbH.
Realtime mixed-format multi-cam
Matrox Axio LE supports the multi-cam feature of Adobe Premiere Pro and goes further to let you view four cameras
simultaneously in real time, even in HD, even if the formats are mixed, provided your Axio system has the proper storage and
system speed. For example, in a multi-cam sequence you could use one DV stream, one HDV stream, one DVCPRO HD stream,
and one uncompressed stream and switch among them in real time.
Closed captioning support in NTSC
Your Axio LE system can be used to edit NTSC video clips that contain closed captioning information on line 21 of active video.
You save time, because there is no need to re-create closed captioning information when you deliver your project.
Captioning information is maintained when capturing uncompressed video. It is also maintained when acquiring DV, DVCPRO,
and DV50 material over 1394. When capturing to DV using Axio LE’s analog and SDI inputs, it is encoded in the DV stream
according to the blue book specification. When capturing to Axio LE’s MPEG-2 I-frame codec, the captioning information is
encoded into the MPEG stream according to the ATSC standard.
You can see the closed captioning on your broadcast monitor as you play and scrub the timeline to accurately make your
edit decisions. You can even apply some effects such as color correction and fades while maintaining the closed captioning
information. Other effects such as cross dissolves and 3D DVEs, however, do affect the closed captioning information so care
must be taken when applying effects.
Because Axio LE maintains the captioning information according to the blue book and ATSC specifications, playout servers that
support these specifications, such as the Grass Valley iVDR, can be used to playout Axio files.
Cross-platform compatibility
If your post-production process involves the use of different offline and/or online suites, you can depend on Adobe Premiere Pro
for industry-standard EDL input and output, as well as more advanced exchange formats such as AAF.
All files and projects created on Axio HD, Axio SD, and Axio LE are compatible with all Matrox Axio platforms.
Matrox RT.X2 files and projects are compatible with Matrox Axio LE.
Realtime MPEG-2 IBP capture from analog SD and DV sources for direct DVD authoring
Matrox Axio LE lets you capture clips in realtime from analog and DV sources directly to MPEG-2 IBP (.m2v) files for immediate
use in your DVD authoring program. There is no need to capture video first, then place clips on the timeline to finally export them
into the MPEG-2 DVD format. This feature is an invaluable tool when archiving stock footage and projects on digital servers or
DVD disks.
