HDV 1440 x 1080 Footage not Understood by Resolve

PostMon Nov 17, 2014 1:16 pm

I imported an XML from FCP of a 1920 x 1080 seq. The media is actually 1440 x 1080 and is displayed properly in FCP. But after bringing it into Resolve (11) it is displayed in a 16:9 pillar box (vertical) format, squeezing the footage and also throwing off size and position of other tracks. Nothing I've tried seem to affect it (settings, etc.). I'm sure it has to do with pixel ratio; but I'm at a loss at this point?

Please help. Thanx. :(

Hello,

Keep your TL in FullHD, but in your media pool, right click every HDV footage > clip attributes > Image scaling = DVCProHD
I remember having searched for a while too, only DVCProHD can fix your scaling pb... ;)

It's been years since I've dealt with nonsquare pixels, but I'm pretty sure you want a setting that specifies 1.333 pixels. Not at my workstation right now so I don't have Resolve in front of me, but I could find it for you later if you'd like.

Doh, I got bit with this a couple of months ago doing a free project for a friend, and it drove me mental. This is a goofy, goofy format. The Clip Attributes settings were eventually the thing that saved me.

I posted something yesterday; but I guess it didn't make it.

Changing the attributes in Media Pool did the trick. Also, after doing a few of them, I selected the rest of the clips (40 or so), right-clicked and changed the attribute, and it changed all of them. Nice job DaVinci! :D

There was a 1.3 aspect ratio choice; but it wasn't quite right. I believe Benjamin is right. It needs to be 1.333.
The DVCPRO HD choice did the trick. Thanks so much Sam. :P

Perfect: I had precisely the same problem with footage from two Sony cameras which are, nominally, PAL HD cameras but use the 1440 x 1080 aspect ratio with non-square pixels. I selected PAL 16:9 at first and wondered why one camera's footage had vars top and bottom. When I output to quicktime and loaded it into FCP to compare to the original timeline I saw that both cameras were being squished.

Just to clear things up. Resolve does have a 1.3 Anamorphic setting under Clip Attributes (right-click the clip in Media Pool). But it doesn't quite fill the 16:9 aspect (left and right). The DVCPROHD choice does, and the stretch is negligable. To do it properly though, without distortion, set the clip to 1.3 Anamorphic, and the Input Sizing, Zoom to 1.026. It will clip top and bottom slightly; but the aspect will be correct.

Anyway, that is my take on the issue. :)
