View Full Version : HD recording formats
Kevin Shaw February 6th, 2007, 02:10 PM It struck me today that the variety of available and proposed HD recording formats is expanding to a point which is becoming difficult to track, so I'm starting a list here which we can add to as new formats come along. Have I missed anything we currently know about?
HDV 720/30p: 1280x720 MPEG2-TS @ 19 Mbps, 4:2:0, MP2 audio
HDV 1080/50i-60i (PAL-NTSC): 1440x1080 MPEG2-TS @ 25 Mbps, 4:2:0, MP2 audio
HDV 1080/24f (Canon): 1440x1080 MPEG2-TS @ 25 Mbps, 4:2:0, MP2 audio
JVC "FHD" 1080/60i: 1920x1080 MPEG2-TS @ <30 Mbps, 4:2:0 (?), MP2 audio
JVC "SP" 1080/60i: 1440x1080 MPEG2-TS @ <22 Mbps, 4:2:0 (?), MP2 audio
JVC "CBR" 1080/60i: 1440x1080 MPEG2-TS @ 27 Mbps, 4:2:0 (?), MP2 audio
XDCAM HD: 1440x1080 MPEG2-TS @ 18-25-35 Mbps, 4:2:2, PCM audio
DVCProHD 720 (varying frame rates): 960x720 @ 40-100 Mbps, 4:2:2, PCM audio
DVCProHD 1080/50i: 1440x1080 @ 100 Mbps, 4:2:2, PCM audio
DVCProHD 1080/60i: 1280x1080 @ 100 Mbps, 4:2:2, PCM audio
AVCHD 720/24p-50p-60p: 1280x720 H.264 @ <24 Mbps, 4:2:0 (?), AC3 audio
AVCHD 1080/24p-50i-60i: 1440x1080 or 1920x1080 H.264 @ <24 Mbps, 4:2:0 (?), AC3 audio
AVC-intra (pending): expect 1920x1080 H.264 @ <50 Mbps, 4:2:2, PCM (?) audio, plus advanced version at higher bit rate
HDCAM: 1440x1080 @ 144 Mbps, 3:1:1, (?) audio
also HDCAM SR
Cineform Raw: 10-bit 1920x1080 @ ~ 80-100 Mbps, 5:1 Wavelet, (?) audio
MJPEG2000: 10-bit 4:2:2 - other details?

Ken Hodson February 7th, 2007, 06:36 AM My impression is this list is stricktly format/codecs that cams currently shoot, no? So that would leave Sheervideo out and I'm not too certain about the last two on Kevin's list. Probably some indie cam using an intermediate PC for recording. Can anyone tell me what shoots Cineform raw and Mjpeg2000 so I can be in the loop. ;>)
Etienne Botha February 7th, 2007, 06:47 AM Call it wishfull thinking on my part. :)
Lossless HD recording to a cheap RAID on a mac.
Hoping anyway

"DIGIC DV ll HD Image Processor
DIGIC DV II is the next generation of Canon's exclusive DIGIC DV signal processing technology. DIGIC DV II processes the HD signal at 1440 x 1080 with 4:2:2 color sampling. Designed specifically for processing the immense volume of information in 1080 HD signals, DIGIC DV II ensures optimal image quality for HD video."
**HD signal at 1440 x 1080 with 4:2:2 color sampling** is this true?
Paul Jefferies February 7th, 2007, 05:53 PM HDV 720/30p: 1280x720 MPEG2-TS @ 19 Mbps, 4:2:0, MP2 audio
HDV 1080/50i-60i (PAL-NTSC): 1440x1080 MPEG2-TS @ 25 Mbps, 4:2:0, MP2 audio
HDV 1080/24f (Canon): 1440x1080 MPEG2-TS @ 25 Mbps, 4:2:0, MP2 audio[/url]
What about HDV 720/24p and HDV 720/25p?

The SI 2K shoots Cineform RAW and the Thompson Infinity will do MJPEG 2000 as one of it's formats.

This is the first level of sampling. The data is then coded into 4:2:0 25mb/sec MPG2 "HDV" when it hits the tape compressor. However, the HD-SDI output does bypass the tape compressor, spitting out the 4:2:2 data at 1.5Gb/sec.

XDCAM HD is 4:2:0 when written to disc. However, if you use component (F330) or HDSDI (F350) output, you get 4:2:2 uncompressed..

HDCAM Records 1920x1080
HDCAM SR records 1920x1080 4:4:4
Greg Hartzell February 8th, 2007, 03:50 PM HDCAM indeed is 1440x1080 and then upsampled on output.
I found this post in another forum a while ago:

Ah, good point. Specs available here: http://www.avid.com/dnxhd/
Jemore Santos February 13th, 2007, 05:38 AM Greg We have over 8 F900/R's plus my manager is ex Sony engineer, and he says the F900's run native 1920x1080 chips
Kevin Shaw February 13th, 2007, 08:37 AM According to the HDCAM specifications on the SMPTE web site, source data from the sensor is subsampled to 1440 luma samples per line and 480 chroma samples per line, at 1080 horizontal lines per frame.
