Hi,

I have using Resolume 1.51 and it's great in soo many aspects... But the biggest reason I moved to Resolume was to get DV In. I bought Resolume first (to do it before 1st of September) and then a notebook (my old PC didn't have firewire). What a dissapointment when I realized the Firewire In produces and image full of horizontal lines. Progressive mode on camera or Peter Warden's Deinterlace plug-in doesn't resolve anything.

DV In as it is now, is unusable and I think it's a pity. Firewire is an elegant solution to transport video, working for several years now, driverless. It seems really un-practical to buy a Video>>USB capture device, with drivers, without knowing if it will work, which quality, etc.

I hope DV In will be well implemented and resolved soon. I have two ideas:

1) The easiest is to implement a 720x576 resolution. This way every pixel goes to every pixel and no strange lines should appear. It's easy and it's elegant.

Has the dissavantage you need a fast computer, but fast computers are here and are cheap now!

2) To create a plug-in which deals with the layer's size and how they are mapped to the resolution Resolume is working. I explain better...

Resolume resizes any video/flash source to the resolution is working on. Passing from 576 lines to 480 creates strange artifacts.

Maybe a Size/Crop plug-in in which you can decide to resize, not resize your video could resolve the issue. Imagine you have a DV In (720x576) and work at 400x300. Maybe you don't want the image to be resized, you may want to crop the image and just use the center of the DV In image...

I hope I have explained myself!

How about DV in working at 720x288 scaled to 576? ie line doubling, it would sort out the interlace scaling and presumably halve the data rate for only a modest decrease in quality?

yes we know that live input is buggy at the mo. we are working on it but it,s not as easy as we hoped ... have you tried not using petes deinterlace plugin but his liveinput plugin?

Hi Bart!

I am happy you are considering this! I haven't tried pete's live input because I thought was for USB, I will try. I have a DV camcorder...

I know it's not easy to solve this thing, going from 576 lines to 480 is not easy even in Premiere or After Effects...
