Oh.. I guess it's an algorithm.. But do you know of any mac apps that has this? AVIsynth is PC-only.
I'm not sure. But I heard that Compressor on Mac can use this nice resize-filter, best quality so far - no artifacts (like with lanczos) and damn sharp.


And to the PC users: It's worth the complex work :)

Do this article give some better perspectives for us with FCP (maybe doesn't solve interlaced vs progressive issue)? Don't have an EX1 to test with

Errrmmmm, as the guy who worked with Rick to bash out that workflow, I'd like to point out that we have NOT looked at NTSC (not enough hours in the day), and we're NOT out of the woods yet with interlace.

Shooting 720p50 for 576i50 seemed to be on the borderline of 'could work in FCP' but somehow doesn't. I want to try downscaling and reinterlacing through AfterEffects and Motion. But frankly this whole NTSC 24/29.97 thing scares me.

In fact the whole SD thing scares me. The time I save with wickedly fast HD transfers and almost DV-like editing speed is totally spent on downconverts. When there's a fluid edit-clientreview-edit thing going on, especially if you're doing web encodes then hoofing sequences to a web server or burning DVDs, the last thing you want is to sit through yet another render (or worse still, export and render).

And what if you're dubbing DVCAM rushes for the client and they want 50i/60i? For each 20 mins of rushes, am I signing up for up to an hour of faffing at my own expense (kit included)?

Alas I don't have access to Rick's EX-1 (I had it whilst he borrowed my Z1 for a mission critical shoot). I have a few clips (too embarrassing to share) to test with, but lack the time to follow through right now. Sorry.

Hi,

for me exist only one acceptable way to SD Downconvert. For best you must have HDV compatible 1080i footage. And when downconverting over HDV camcorder (record to tape in HDV mode and then downconvert over camcorder to DV AVI file), so this is HW way not software, but best result without flickering line or soft image. I try many many software, but this way is best and simple

all problem in software downconvert is resize filter mode. Only in one software i can change resize mod, is freeware virtualdub, precise bicubic or lancoz3 is best for interlace footage. I dont know why pro cut software like vegas, premiere, fcp dont use change resize metod, when we have problem with line problem and soft image..

btw: Converting over virtualdub with lancoz3 resize mode is best software downconverting but not good like from HW HDV downconverting way.
