You drive the recorder unit with Blackmagic's Media Express software which includes Sony-compatible RS422 deck control.
I didn't spend a lot of time analyzing quality, since the typical user will encode at high data rates that streaming will minimize any quality differences between different encoders.
The device might be quite handy in capturing good quality (even HD) video feed, and streaming compressing it.264 without loading the CPU on the capture PC too much.
After seeing these results, I captured a short HDV test clip at 24p, which Pro Recorder again captured.97, in comparison to Premiere Pro, which captured at 24p.Of course, you can fix the pixel aspect ratio issue in a video editor, but that again obviates the benefit of a real time archiving or distribution solution.On the encoding side, recorder there are four presets for Apple TV and iPad/iPhone 4 - both produced at 720p - and uploading to YouTube at 720p or 1080p.If you choose one recorder of these outputs, the Pro Recorder will render at these resolutions, though it won't scale SD footage up to 720p or 1080p, which is the right result.I was wondering if anyone on the list might have an idea if the upcoming Blackmagic.264 Pro Recorder would work with the lecture capture agent?Encoding parameters used by Pro Recorder.Compatibility was also perfect: video produced with the iPad/iPhone 4 preset loaded and played on both devices, while both YouTube clips uploaded and produced the correct number and resolution of files on YouTube.Even if you could produce at 640x360, you can't recorder change the.264 profile to Baseline, streaming so the files you produced wouldn't play on those devices anyway.So, if you want to produce HD footage at 640x360 resolution to play on older iOS devices that can't play 720p, you can't.Regards, otto J Wittner, on 12:35 PM, Sami Andberg wrote: Hello, Were laying out specs to set up a few Matterhorn lecture capture systems for a pilot in our university. The flexible Pro Recorder enables you to capture old or new video formats into the same file formats used on the web, iPad, streaming iPod, iPhone, Apple TV, and more, providing a gaga convenient solution to capture from professional broadcast decks directly to SD and.264.
Overall, I'm an unabashed supporter of Blackmagic capture cards, and have recommended Decklink cards many times and use them frequently in my work.The application was available in binary format only.Hi, At uninett we have managed to interface with recorder a Black Magic Intensive Pro capture card.Other Issues, getting back to the limited nature legends of the Pro Recorder's encoding controls, let me reiterate that you can't change the output resolution beyond choosing one of the four presets.Capture directly from SDI, hdmi and component analog video with embedded SDI, hdmi and balanced analog audio inputs.Key Features, professional Encoding, sD/hdmi Inputs Support SD/HD Formats, maximum Flexibility.For high bit rate tasks like archiving and production for all of the Recorder Pro's presets, quality should be fine.Media Express Software Included, the, software blackmagic Design.264 Pro Recorder is designed for the industry professionals who require sung professional encoding from SDI, hdmi, analog/component composite, and balanced audio.I don't have an Apple TV set-top box, but the Apple TV file played fine on my Roku, which has similar specs.You can see this in Figure 1, two screen shots from Adobe Premiere, with the top image showing the file Premiere captured from my source tape, with the correct aspect ratio and frame rate, and the bottom showing the Pro Recorder capture with both variables.Plus you get RS-422 deck control and Media Express software game for Mac and Windows!
With 16:9 footage, the encoded file was still 720x480 with a pixel aspect ratio.0, rather than.2121, making the video look too skinny.
Premiere captured h.264 pro recorder streaming my 16:9 DV 24p video at the right frame rate with the right aspect ratio; Pro Recorder didn't.
