Interlacing Woes- CS3
Working on a video for our wedding. Just recently purchased a Sony HDR-HC9 miniDV high definition movie camera so that I can best work with footage in Premiere Pro CS3 without having AVCHD issues. This post is wordy but it’s an attempt to get across as much detailed information as I can.
The question at the end of all this is, how can I get best results for playback on my computer to be played through a VGA cable projector at our reception?
I’m working on a laptop that is not enabled for what Sony calls ‘Full HD’ or simply 1080p display.
I am no expert with settings for video but I’ve been lurking around and Googling enough to know basic terms and to dabble with settings. That said I chose the following at setup, stop me if I took a wrong step somewhere.
Editing Mode: HDV1080p
29.97fps
Pixel Aspect Ratio: HD Anamorphic 1080
Fields: No Fields Progressive Scan
Display Format:30fps Drop-Frame TimecodeThe preview footage looks smashing.
On advice from a friend from long ago whenever rendering I render as Microsoft AVI without any compressor. I then take that into Virtual Dub and compress it with Xvid. This could be totally wrong but it’s what I know. If anyone has any advice to this point I’m all ears.
Now, the ultimate playback looks horrific. I realize this is because my laptop monitor is not designed for 1080 display. However, I was a bit shocked when I plugged the laptop into my Full HD Bravia via a VGA cable and saw the same terrible quality in the final AVI.
I realize this has to do with interlacing and/or deinterlacing. From reading past threads I’ve gathered that in my case, deinterlacing would be a BAD thing. Understood. But what can I do to make this video look better?
Interestingly enough. I was working on a different but related project. I was doing some chroma key work where I imported footage from the camera into a project where the Editing Mode was DV not HDV. The HDR-HC9-shot footage looked remarkable. Really slick.
What gives?
In the end if this doesn’t work should I simply redo the project in a DV editing mode? Just a coincidence?
Thanks guys, you rock.

Have you tried a final output with PPro instead of Xvid?
The workflow where you use HDV in an uncompressed editing environment is optimal for production where you are trying to get HDV to hold up like a higher end format, but many people use a typical HDV workflow everyday and like he results…and of course just using the HDV material in an HDV project is less of a hassle than creating large uncompressed HD files and then relying on freeware for your master output.

Thank you for your reply! I would love to render final output through PPro, I’m simply not sure what options are best for the material I’m working with regarding File Type & Compressor (not to mention any other tweaks).
I’ve looked around for some advice and while much of it is way over my head, the most confusing part is that everyone seems to have a different say on what works best. Which is probably because of so many different kinds of projects.
That aside, if that isn’t the source of the ‘problem’ (if there actually is one and it’s not just a hardware limitation) I’m most curious as to how the video might be displayed properly, that is to say in similar quality to 1080i in which it was filmed. I expected the picture to look clear when viewed on a 1080p TV set but I was shocked when it looked exactly the same as on my laptop monitor. Is that a limitation of my laptop? Say for example, were I to play the exact same final output AVI file on a computer designed for 1080p display (which I assume would display 1080i ‘properly’) would those horrid lines vanish?
I apologize if this sounds naive but I’ve ‘learned’ PPro through trial and error over the past year with help from sites like this one so while I can whip something fancy together, I have no idea about the technical theory involved in output and until now it hasn’t been an issue. But for our wedding, I’d like something that really looks fancy.

>I plugged the laptop into my Full HD Bravia via a VGA cable and saw the same terrible quality in the final AVI.< You will get the same result as on the desktop display, using the VGA option is just using the Bravia as another computer display, if your laptop has a HDTV out like component or HDMI and you use a player it would improve

Fantastic! Thank you very much for that info! I will attempt it with an HDMI connection on my better half’s laptop when she’s back from Tokyo to test for future reference.
Incidently I sifted through posts here and elsewhere into the wee hours of the morning looking for other ways around the ‘problem’ and although I found some fascinating new info, I ultimately decided to be a loser avoid it completely. The footage looks smashing in NTSC/DV Widescreen and since I’ll most likely be using my own laptop to display the video through a projector anyway, I’ll go with that for now.
Next laptop is HDMI or bust!
