Hi Laurance -

gurk...
so which codec do you use for fastest re-render w/o attendant loss.
I do a LOT of "pre-renders" as I edit and then re-render the entire show, before I once again render to MPEG for delivery.

Any thoughts?

(oh - I MISS that "No Recompression Necessary" screen.)

Did 9c not smart render AVCHD? Or does the 5D use a different flavour?

I'm a sort of "set it and forget it" kind of a guy.

Add that to the fact that I've been using Vegas since ver 3, and there's a lot to change, revise and forget.

I sort of remember using Cineform Neo (a paid for third party convertor) to convert my 5D footage for use in Vegas 9 or 10, and then it was no longer necessary.

Maybe that's where the No Re-compression was lost??

I have no recollection other than that I miss that part of the process.

To vicmilt:
I am not sure what you are attempting, but if you are editing with more than cuts of the original -in order to step to a final - you may need to render to intermediates. The question is what delivers the best edit (speed, etc.) at the least loss for an intermediate.

In my opinion the Cineform codec can not be beat in the tradeoff. Many others have differing opinions, but they are not able to argue best of all tradeoff .....IMHO>.

Which codec is the Cindform? Or is it one you have to buy and install?

Or where is it located on V Pro 11? And /or what is it called?

Many thanks in advance.

I own a two year old Cineform Neo - will that work in some way?

Cineform is the codec technology that you are speaking of...it is a third party license - the brand now owned bythe company GoPro. It has a specific license methodology that you must employ or get into a whole lot of trouble fundamentally and legally. So you must learn their method.

You may be able to use the license you already have, but upgrade the exact version in software of it...and mabe not.

I think your Cineform Neo is the current software (though probably it could use an updating if not an install). I stopped using Cineform a couple of years ago because of a random black frame problem. Officially it has been fixed, but there are still complaints of it here and there, so I haven't ventured back. The black frame problem is particularly bad because you have to kind of go through the project frame by frame to make sure it isn't there. It is so horribly time consuming that I just gave up.

XDCAM .mxf and XDCAM .mp4 are both great formats. XDCAM .mxf has an advantage in that you can use higher bitrates, but has a problem in re -smart-rendering parts that were already smart-rendered. XDCAM .mp4 is the same mpeg2 codec but in a .mp4 wrapper and limited to 35Mbps. It smart-renders nicely, including parts that were already smart-rendered. It also plays nicely in VLC and encodes in Handbrake with stereo audio. XDCAM .mxf will not encode both stereo channels in Handbrake.

If you are smart-rendering footage that is progressive, I have found it important to flag the video clips as interlaced. For some reason, Vegas has never been able to smart-render progressive flagged clips for me. Strange because others report that there is no such problem.

Thanx
