stuttering and jagged edged exported project problem
Beware, novice at work here!!,
Editing a hospital arts project in PAL DV anamorphic and we’ve used a combination of footage shot on a Sony Z1 and cheap sony minidvd cams, all at 16:9 though I know at least the handycams aren’t true 16:9!
We also have a lot! of jpegs in the timeline, I know this is frowned upon but I’d really like to avoid converting them all now.
Also in there are a few motion graphics (using layers of a PSD)
And I’ve probably commited another sin by using FCP titles and keying their scale for zoomed text.
Ideally I do not want to start from scratch with this thing as the deadline is fast approaching.
When I have exported through Quicktime conversion and then burnt to dvd through iDVD (for speed and simplicity…..I did say I was a novice!) the result on my oldy worldy non lcd tv is a juddering in places, some worse than others when FCP zoomed titles come up you get the jaggedy edged footage, even the simplest footage seems to be almost missing frames? if that makes any sense. But the weirdest is that even the simple scrolling text of FCP is stuttery!
I have also exported the project in sections through compressor with a standard set up 90 min compress but the look of that stuff is the same when viewed on my computer monitor in QT
Now I have considered the possible reasons for this and would really appreciate some advice on narrowing this down so I can get it sorted.
so here goes:
have I deinterlaced unnecessarily? (checked as standard in QT and compressor export)
is it because I’ve used jpegs (these are often used as backdrps to chroma keyed footage, though not on all of the stuttering fooage)
is it because I’ve used jpegs/ psd’s in motion?
is it because I’ve used FCP titles?I plan to do a number of tests but if anyone out there can narrow them down for me that would be great.
export a series of short ‘problematic’ clips without deinterlacing.
redo motion titles using tiffs
re do all FCP titles in motion
convert all jpegs to tiffs (that’ll take a long time)
try to send it all through compressor (not QT) without deinterlacing by deleting all render files (compressor fails to convert the whole file and having broken it down to find rogue files and deleted them deleting render files has been suggested)God that was longwinded.
any help much much appreciated!!!
thanks in advance
johnoh I’m working on an octo 3ghz with 4gb ram on leopard.

I would start with the deinterlacing. My guess is that’s what’s causing the jagged edges on your motion.
Also, what kind of file are you exporting when using quicktime conversion? And what was your reason for using quicktime conversion for export? The only reason I ask is that the conversion may be causeing the jumpiness in the video.
Just trying to get some more info…

Thanks Dan, I was advised to export via QT conversion as the vid file would file when exporting to compressor. I think (i’m not at the computer until early next week)I selected mpeg2 if this is possible? Of course then instead of converting that .mov file in compressor I naively just threw it into idvd to get a quick draft copy out to the client.
The motion files and FCP titles all stutter and when you have a zooming FCP title over a piece of footage you get the jagged lines.
any other thoughts very welcome, thanks again for responding

Hey John,
iDVD will automatically convert your dv quicktime to mpeg once you add it in the iDVD project. I would just use export>quicktime movie, use the current settings, and then put that into your iDVD project.
If you have an anamorphic sequence that you want to letterbox, just nest your anamorphic sequence into a regular dv sequence, do a full render with audio mixdown, then export that sequence using export>quicktime movie with “current setting”.
Good luck,
Dan

Thanks Dan, that makes sense I’ll try it on Tuesday. My intention is to trial exporting a number of smaller clips from the bigger project. Once I have a clean Mpeg2 version I’ll export the lot.
thanks again
