Editing Progressive vs Interlace

Thanks for the tip re uprezzing HDV to 1920. Since I have started shooting in EX1 1080HQ it is strikingly apparent that compressing the sq pix format produces siginificantly better looking m2v, h264, whatever.
So, for 2 cam shoot- EX1 + V1, the smart move would be to use Prospect 1080x1920 30p timeline, deinterlace all footage on capture with CF, and uprez the HDV to 1920 sq pix on capture.
Brilliant!

Ingesting everything to CFHD as 1920 30p seems to work great. Does take a little more time for HDV capture and convert, but working in 1920p, with the ability to export and compress to delivery formats directly from the timeline more than makes up for that.
Thanks for the tip.

Certainly our experience matches yours! I guess we just hit the sweet spot for the best final output (from tape or compression) you can squeeze out of Sony HDV cams?

The only way to better it, is to capture directly from the cam, using the HDMI or SDI output. Especially for greenscreen/bluescreen work, the lack of MPEG blocking and the direct CF compression can really smooth things out.

Now if we can just swing the $$ for a EX3, and get our new custom field recorder down here, we'll be flying high! It's a tiny little industrial quad computer that converts to CFHD in realtime from the HDMI or SDI cam outs. It's more pain to DC power it in the field, but the end results can be worth it.

We'd like to go to a RAW workflow in the future, but I guess that will have to wait a bit yet. Meanwhile, we took that CF Prospect 2K/4K upgrade route to assure the future at a lower price...

My problem is that right now the cameras and workflows are providing more quality than I can utilize with my modest skills. I'm suddenly pausing to learn how to be a better photographer so that I can actually deploy all of this amazing quality I now have at my fingertips. It's come a very long way from the DV world of just a couple of years ago. Amazing!!

hi,
would be it possible in a future release of HDlink to deinterlace a CF avi interlaced file to CF avi progressive ?
we can only deinterlace m2t to avi;

it seems to produce a good result than other methods and i would be usefull.

HDLink already has this capability - that's what the "convert" tab is for!

I'm trying to get a feel for a work flow here and after reading this thread several times, I came up with this, but I would appreciate it if you guys would comment. I have AspectHD and Premiere Pro CS3.
1. Capture 1080i footage with HDlink, automatically converting to AVI,
Cineform encoder - frame format - automatic , Check Deinterlace, and make resize video - none.
2. Import this footage into Prem pro project Cineform HDV 1080i and edit.
3. File - Exprt - Movie and use Cineform HD export with fields set as "no fields".
4. Import as timeline into Encore CS3 BluRay Project and let Encore encode into MPEG 2 file for the DVD.

Actually, this gives me pretty nice TV from the DVD, but is there anythng wrong with this? Thanks in advance,
John Rich
