Is 'H.264 dvd studio pro' 720x576 from compressor (pal) compatible for SD dvd.

Hopefully an easy one....
Im creating dvd files in compressor for a 120mins sd dvd. Im not happy with the mpeg2 quality as it seems to add jagged lines. Ive noticed H.264 for DVD Studio Pro option seems to be best. If I change the Video Format to pal setting (720x576) will this be fine for sd dvd in studio pro? Im conceded as the compressor Inspector description still states: DVD type: HD DVD but at 720x576.
thanks in advance :)

DVDs use MPEG2 Elementary Streams.
HD DVD is a format the died years back.

Please read the sticky at the top of this forum and provide complete information.

I can guess the jaggies are from downscaling but without giving complete information you're just going to get guesses which may be wrong.

Filmed on 60D, edited a 90min 3 camera concert. Exported from FCP as QT with 'recompress all files' clicked. Using Compressor to build / format in Dvd STudio Pro.

The initial problem was I was new to DSLR editing and I wasn't aware of app pro res converting. It edited ok and played fine in fcp timeline. However, the only way I could get a clean export was by clicking 'recompress all frames'. Long story! Anyway I am now using compressor to make sd dvd files. I have used trial and error and the only dvd setting (without jaggedy lines) seems to be 'h.264 to dvd studio pro'.

If I choose this setting and change the frame size to 720x576 16 pal, will studio pro accept it as though it was sd. It needs to be good quality as it's being mass produced.

I'm hoping theres a simple answer, I can't seem to find a similar situation on the help forums as it's quite specific.

Thanks again

[Leon Willis] "Filmed on 60D"

Which has a plethora of frame sizes and frame rates. What did you use?

[Leon Willis] "Exported from FCP as QT with 'recompress all files' clicked. Using Compressor to build / format in Dvd STudio Pro."

Version numbers?
QT is a container. What is your exported codec, frame size and frame rate?

[Leon Willis] "I have used trial and error and the only dvd setting (without jaggedy lines) seems to be 'h.264 to dvd studio pro'. "

You're probably having downconvert issues which is creating the jagged lines.
There's no H.264 to DVD Studio Pro setting. In Compressor 3.x there was HD DVD: H.264 preset. HD DVD is a dead format. There are no jagged lines because you are not downconverting.

I've changed 'field dom' to 'progressive' which seems to have done the trick so far.

That would get rid of issues around interlacing.

I'd have thought your source is progressive given you're shooting with a DSLR.
These days I rarely shoot interlace. The only reason I can think of is for 1080i broadcast.

If it's exporting H.264 that might exacerbate the problem. Try setting the timeline to Apple ProRes 1920x1080 25fps (PAL) and rendering and exporting that.

spoke to soon, its still jaggedy. I'd avoiding going back to FCP as 'recompres' export takes hours. I don't think this will help as it exports fine in compressor as hd. no jaggy edges. It just seems to be when i click Mpeg2.
cheers

Right. After a lot of trail and error. Ive re-named it something entirely different, highlighted the 'Dolby Digital ac3' audio file (as opposed to MPEG-2.6 .mv2 video file) just before I click submit, this seems to have done the trick. WHY this works I have no idea.
Hope this saves someone else a lot of time if they ever have the same pridiciment.

You should not be recompressing all frame i n the QT export. Uncheck that box.

Just to update anyone who may be stuck with this problem. It turned out that this didn't work for all parts, the only success was to:
export SD version from FCP
then
export as SD from compressor.

This was my original question & I tried to find alternatives to save the quality but to no avail. thanks
