beatin the reds into the ground...

following a question i posed last week... dvcproHD project

ok. here is my problem. movie rendered out of AE lossless+alpha looks good. looks good also when imported into FCP (and seen in viewer) but when dropped onto a dvcproHD timeline and rendered it goes to hell.

see image:

Wayne, do a quick export of those frames from the Timeline and open in QT,
or check on an external monitor.

as you know, FCP canvas is no way to judge.

QT player is just as bad. and where the problem was first discovered in fact.

have been discussing with shane and one of his cohorts off line this evening and it seems it may possibly just be a "feature" of the dvcproHD codec. which is shocking considering how well its served me to date ... : (

id hate to have to tell exxonmobil "uh, you have to change your company colors because my codec cant handle red."

maybe it's time to switch to ProRes?


nick

may well be...

what would the workflow be if im shooting in dvcproHD?

Edit everthing as DVCPRO HD...when you lock picture, copy and paste thing into a ProREs sequence and render. Test to see.

Simliar post on DVXuser. 'milksac' suggested this;

The problem is that Adobe and Apple use the QT gamma tag differently.

Here's an article that should help.

The links don't work...

Wayne, anyway you can upload a frame from that?

Try this one;

If that doesn't work then go to
DVXUser
then scroll down to the AE forum
it's the thread titled "can someone explain this?"

This has the original link

Lol. Yea, there's a gamma shift between the 2 pictures. It's the pixelation on the reds, looks a little like rendering in DV, and worse.

Hmm... Have you noticed that if you pop the animation into a timeline set to a different compressor, there isn't a quality jump before and after rendering? DvcproHD seems to have it bad though. Perhaps it's the 7:1 compression ratio.
