Why does it work?
 
I thought I'd try pan & scan reduction to DV without the extra step of editing in a Cineform preset outputing an HD avi and resizing in an SD project.

I captured HDV with OnLocation, transcoded with HDlink then brought the CFHD avis into CS3 in a standard resolution project. I edited, resized, pan & scanned frameserved to Tmpgenc express output files for Encore and burned my DVDs. It worked.

Shouldn't I have had problems with field order? or problems using the CFHD in a SD project? Waiting for the other shoe to drop.

Brad... please forgive me for sidetracking your thread.

Can you explain the function and advantages of the frameserve process you use?

A quick thought on your question at hand... did you output to a progressive or interlaced frame? If interlaced, on closer inspection, you may have an interlacing issue with your HDV content... but that may be difficult to spot after rescaling down to SD?

I've mixed SD and HDV materials in Premiere 2.0 without any problems...that's with a progressive output though... haven't tried the same to DVD.

No problems if you do it all correctly. Clearly you have.

I don't have my decoder ring... what does this mean?

It means he didn't have problems because he didn't screw up. ;)

David Newman December 19th, 2007 12:24 PM

Sorry about my cryptic response. :)

I find that Debugmode (free) framserves nicely to Tmpgenc using a form of YUV. It saves time and space. I see that Cineform has incorporated some of the Tsunami stuff so I guess I'll have to try that for encoding. CS3's media encoder just isn't good enough. Better than CS2, but not enough better.

I used to use Tmpgenc for resizing, but now I'm kinda hooked on pan & scan resizing in an SD project. I just thought you couldn't edit with CFHD in an SD project. I guess you can.

I'm still confused about the field order though. I take a upper first HDV, encode to a upper first CFHD, import it into a lower first DV timeline and it works. I think one of the programs is fixing it for me but I don't know which one. If I don't know, I'm afraid I'm going to mess up later.

That's what I thought too. I'm not using progressive so ???

Brad... probably the only way to reveal any field issues is to view a DVD on a CRT.

Have you tried reversing the field dominance of your HDV clip in your timeline... notice any change? Is there a lot of movement in the shot?

TMPGenc rules.... It's great for rescaling, deinterlacing, etc... I love it.

I still don't understand the frameserve process... I guess I need to do some research to learn about it.

For the pan and scan capability, After Effects is my first choice.

David: I love to harass your typing..... My theory is that you Think @ 300wpm, and Type @ 60wpm! Your presence here is invaluable, I hope you don't mind an occasional jab.

Actually, one of the nice things about editing HD in a DV timeline is that I can preview on a standard monitor with the 1394 out.

But, - what started all this was that I made a bunch of DVDs for a client. I previewed the DVDs on a standalone player and crt, didn't see any problems, and sent them out. It was later that I started thinking that something wasn't right and was going to come back and bite me.

Yep, It actually looks worse when I open in a upper first DV project, - well in preview anyway. No stuttering, but the resolution is down, - strange.

Agreed. Now I have to find out how much TMPGenc is in ApectHD It'd be nice to output to Encore from Premiere again.
