True Hi-Data Rate Editing

[John Richard]

Have never been able to wrap my head around this concept.

With the wonderful Nano and XDR recorders,we have the capability to shoot video at up to 280mbps.

But it seems that when editing anything other than straight cuts (such as color correction, dissolves, etc), we end up with a final 50mbps data rate quality.

Both FCP7 and Premiere 5.52 put you back at the XDCAM 422HD 50mbps data rate if anything other than straight cuts was done.

Is this correct?
If so, are there any future plans for NLE's to actually let us use this higher quality video currently in our hands from the Nano and XDR (and upcoming Gemini)

Dear John,

FCP does put you back to 50 Mbps if you do color correction or cropping.

You can drag and drop our footage into a ProRes timeline and unless you do color correction or cropping, our 280 Mbps footage will be left intact (as I understand it).

For Adobe CS3, CS4, you can use the MainConcept codecs and output XDCam at 280 Mbps.

Also, I thought that with the latest versions of Adobe 5.5, you could also output at 280 Mbps.

I do not know, at this time, if the MainConcept codec can work with Adobe 5.5.

With FCP if you go to the timeline settings you can change the render effects settings to a different codec than the timeline codec. If you use ProRes HQ then any effects, colour corrections etc will be rendered at 220Mb/s ProRes which is a better match to 280Mb/s NanoFlash material than 50Mb/s XDCAM.

Thank you Dan and Alister so much for the response.

I am going to try to get an answer from Adobe re: how or if it is possible to maintain and output the high data rates we have available from these fantastic Convergent Design devices. So far the only Sequence Settings for XDCAM 422HD that I can find in Premiere 5.2.2 are 50Mbps.

Really liking PPro 5.5 by the way - the speed is very liberating with how easy it is to when you are editing/creating/taking chances with effects. 64 bit, Mercury, and Cuda take a lot of the wait away.

Thank you Alister for reminding me what Tommy of CD told us a long time ago - I had forgotten about the FCP setting of rendering for effects only and leaving the base un-effected file in it's CD high bit rate beauty.
