Hi Carl,
I hope you’re well.
I did email you a while ago regarding encrypted DCPs but I’ve hit a new unrelated wall
I’m hoping you can help with.
So I’m hoping to rip this crappy 30fps NTSC DVD that’s 1:66:1 “floating” in a 16:9
container. I’ve done all the zoom ups, re-sized and re-edited the subs and my
master MOV file is free of deinterlacing errors. I’m very happy with it….well, as happy
as you can be from such a crappy source :-/
But here’s the very weird thing. DCP’ing “creates” visible deinterlacing errors?? Ones
not present (or atleast visible on the master file) but very pronounced on
the DCP. [IMAGE]
That is odd. I think the decoder in DoM must be doing something odd. Is
there any way you can send me a few seconds worth of the source file (just
enough to see the artefact)?
You can use carl(a)dcpomatic.com or cth(a)carlh.net to email me off-list.
I suspect it’s picking up on imperfections in the
image?? Never had this with DCP O’Matic before, it usually does the opposite and removes
the imperfections??
The obvious suggestion is to re-encode using one of your de-interlacing filters…the
trouble is that’s what you’re looking at above, the second pass with the first
filter enabled L All it seemed to do was smear the image.
Do you have any advice with this? I don’t want to keep doing multiple passes and hit the
same issues as sadly the film is feature length with no other masters
available L
Huge thanks as always. Feel free to add the Institute of Contemporary Arts in the UK to
your impressive roster of clients. We’re on the Mall, so you’re (rightly) a
stone’s throw away from royalty now and deservedly so J
Thanks a lot, I will add ICA now! Very cool!
All the best,
Carl
