5D Mark ii — HDMI > AJA IoHD > Final Cut Pro

[Arthur Aldrich]

[August Miller] “1.) Am I correct in assuming that the Mark II delivers uncompressed video out through HDMI? “

That is not really true. The live video output is not 1920×1080 video. You can get a picture out, but it is at best 1320 x 700. Not a video friendly hd output.

If you are talking about playback, then yes 1080i video plays out.

It’s actually worse than that.

The “live view” video sent out the HDMI cable during 5dMkii recording is SEVERELY bandwidth and raster size limited. This is because the stock camera can’t write to CF and export full raster at the same time.

There’s been some talk of Tramm Hudson hacking the camera firmware to enable this – but as far as I know, it’s not been done yet.

The correct workflow is to take the Canon’s clips and transcode them to ProRes 422 inside either Compressor or directly as Quicktime Pro Export from within the FCP timeline.

Editing 5dMkii native files in FCP is possible if you have very ROBUST hardware setup – , but it’s NOT currently efficient.

FWIW.

August Miller has suggested a very interesting idea – taking the feed through HDMI to AJA box and sending Prores 422 directly into FCP, therefore avoiding h.264.

I have been consideringexactly the same thing, and made a simple test: I filmed a scene on the 5d, then, with HDMI linked to an external monitor, watched the filmed footage and the live feed and compared them visually. The live footage was clearly superior – bit depth seemed much higher, gradations more smoothly dithered, and banding substantially reduced. It all looked positive.

Then I read Arthur Aldrich’s post saying that the HDMI feed is 1320 x 700, not 1920 x 1080 , which was disappointing. Can I ask where this figure comes from? is it during filming? I am working on the assumption that for this method to work, we would not press the record button at all.

Of course the simplest solution is that Canon offer us a choice of Codecs….

Yeah you don’t want to bother with the 5D’s HDMI output- it’s much lower resolution than the recorded signal. Total catch-22- you either get the 1080p resolution with H.264 or without and lowered res.

HI,

I had the same idea, capturing the EOS 5DMKII HDMI Output through mi IO HD, but the first try was not successfull. Did you get your system running?
Somewhere i read, that during live view and NOT recording the hdmi output was full HD, so I guess somehow it mst be possible to capture that signal.
There might be another problem: The IO HD supports only 1080i30, but the EOS delivers 1080/30. Maybe the IO HD does not understand that incoming format.

Maybe it becomes neccessary to buy a AJA min Converter HDMI to SDI?

Hopefully you have a solution.

Thanks

Tim

p.s.

I am wondering, why there is only you and me who had this idea, or did you find anyone else in the world wide web, who has this problem?

i think with magic lantern your able to output full HD, but everyone here says it is still not a clean 4:2:2 output

im also interested in a 5Dmkii and ninja, to record with its large sensor

in fact any large sensor hdmi equipped camera will do with the ninja
