Pushing/Recording format
sdi:PORT(/FORMAT)
Example, output SDI on DeckLink SDI port 0 using autodetection
sdi:0
Example, output SDI at 1080p60 on Decklink SDI port 0
sdi:0/YUV 4:2:2@1080p60
Video format: UYVY (YUV 4:2:2). Resolutions/framerate dependant on card Audio format: PCM
Other video formats only as passthrough
tip
- In most cases not setting the format is best, let the auto-detection handle that.
- You will require a raw
UYVYandPCMtrack to push over SDI
