The Cisco MXE 3500 also interoperates with the Cisco TelePresence
®
Recording Server, which allows you to
take recorded video using the Cisco TelePresence system and repurpose the content so it can be played back
on a variety of devices with the appropriate postproduction services performed on the content.
Q.
What formats does it support as input and output for file-to-file transcoding?
A.
Input: MPEG-1, MPEG-2, MPEG-4, H.264/AVC, QuickTime, AVI, Windows Media (WM7, WM8, WM9), VC-1,
Flash (ON2-VP6, Sorenson Spark, H.264), DV (DV25, DVCPro25, DVCPro50), 3GP (H.264/AVC, MPEG-4,
H.263), MP4 (H.264/AVC, MPEG-4, XDCAM EX), MXF OP1a (MPEG-2, IMX, DV25, DVCPro25, DVCPro 50,
JPEG 2000), MOD, TOD, MTS, AVCHD
Output: MPEG-2 transport streams (standard definition [SD] and high definition [HD]), MPEG-4/H.264 transport
(SD and HD) streams, AC-3 Audio, Layer II Audio, Windows Media Proxy, MPEG1, and MPEG-2.
Q.
What formats does it support as input and output for live transcoding?
A.
Input: MPEG-2 codec in MPEG2-TS container, WMV.
Output: WMV, FLV, and H.264/AVC.
Q.
How much video expertise is required to be an administrator for the Cisco MXE 3500?
A.
The Cisco MXE 3500 includes predefined profiles that allow administrators to perform media transcodes and
postproduction activities without needing a high level of video expertise.
Q.
What level of automation is offered?
A.
The Cisco MXE 3500 includes predefined profiles that allow you to simply move files to a "watch folder" from
which "jobs" are initiated and completed without your intervention. With Release 3.3, the level of automated is
increased so the Cisco TelePresence Content Server can submit a video to be enhanced then published into
the Cisco Show and Share application without user intervention.
Q.
What are the critical parameters for capacity planning?
A.
The critical parameters include the amount of video content, the length of the video content, the percentage of
video content that needs to be transcoded, the types of endpoints targeted, turnaround time required for
processed content, and SD versus HD content.
Q.
Where are Cisco MXE 3500 media-processing devices typically deployed?
A.
Cisco MXE 3500 devices are typically deployed in the data center.
Q.
Does the Cisco MXE 3500 support live transcoding?
A.
The Cisco MXE 3500 performs real-time transcoding of IP streams, in addition to file-to-file transcoding.
Q.
Is the Cisco MXE 3500 just a transcoder?
A.
No. The Cisco MXE 3500 goes beyond the bounds of only transcoding video on demand (VoD) and live content.
In addition to transcoding, the Cisco MXE 3500 also allows you to do the following:
●
Perform complex video editing that includes the modification of visual attributes (for example, color and
contrast), stitching clips to form a single contiguous clip, adding bumpers/trailers, providing speech-to-text
transcripts, and more
●
Add graphic overlays including title slides, captions, logo insertions, watermarking, and more
Q.
How do graphics features complement the media-processing capabilities of the Cisco MXE 3500?
A.
Dynamic graphics updates occur during transcoding.
●
Multiple simultaneous transcoding sessions with customized graphics are supported.
●
You can add overlay graphics on all output formats, including logo insertion, watermarking, title overlays, and
more
