Project Burned to DVD: Jagged Lines?
Haven’t had this issue before but want to run it by you guys so I can better understand this.
I have a project, 1920×1080, I did a few color corrections and just wanted to burn to DVD to test my footage and see what it looked like on a TV. When I burned it to DVD I used the Share function on Final Cut and shared it to DVD. When I played the footage on my TV it had some jagged lines on some thin black lines that were in the shot. Also the widescreen bars I had put on had a tiny gap between the lower part of the top bar and then a very thin black line. Same with the bottom bar.
Just wondering what would cause this and if it can be fixed easily.
Thanks

ahh geez I think I just figured it out.. the Share function burns to 720×480 which is probably having an effect on the footage. Does this make sense?
-
Well ALL DVDs are standard definition so 720 is normal.
**Hindsight is always 1080p**

I would think that FCP doesn’t do a very good job at converting HD to SD. Use Compressor for the best results (or After Effects).

The share function is compressor.

Be sure to adjust your frame controls and data rate for best results.

For DVD compression from HD sources, I first do a conversion from HD-SD with the best settings. Then do the DVD m2v compression in a second pass. This is overall faster, as well as cleaner.
FCP Share or compressor are dog slow with HD-MPEG2 conversions and not clean either.

Fields. Plain and simple, it’s a field issue. HD is generally upper and SD is generally lower (based solely on standards, which it sounds to me you are doing). The best way is to export the HD to SD DVD, changing (in compressor) the fields from upper to progressive frame rate. For good quality settings, I’d recommend : (Under Frame Controls–turning it on) Resize Filter to better, output fields to progressive, Deinterlace to better, and going with the rate conversion on best. You can go higher or lower on these settings, (higher WILL be a lot longer) but I’ve found this to provide acceptable results.
But that’s just what works for me…. 🙂

Neil, when you say you convert from HD – SD first, how do you do that? In compressor? Or somewhere else?
-
Yes, convert from HD to SD first, in Compressor. You can make these settings as good as you need and have the time for. I usually do some small 5 min segments at various settings to arrive at the best settings. Also, by timing what it takes for 5 mins, one gets a sense of what the whole program will take.

My sequence has an aspect ratio set at HDTV1080i as that is the only thing that will give me my true 1080 that im shooting in. But my source footage is progressive. Does this have anything to do with the jagged lines? Maybe fields are being affected. Also which SD drag and drop setting should be used? DV NTSC?
