custom size sequence render/export issues
we make content for a super wide screen projection screen and use custom sequence settings to acheive this. Our sequences are 2160×576 PAL DV. each piece is 3-4 minutes long. we are having several issues when it comes to exporting quicktime movies.
the first is that around a 3rd of the way through the export (typically 2 hour long exports from a G5 2.0g) the sequence shows the red bar over the entire sequence, if the export is successful then this seems to right itself after the export is done and the quicktime movie is ok in that it doesnt have any blue – unrendered slugs.
sometimes part way through the render it will just choke and give an out of memory dialog box. I though this could mean we have a corrupted file or clip – but its way too random for that – sometimes it works sometimes it doesnt.
the third issue is that the quality of the final quicktime movie is poor – looks like its been rendered to medium or preview quality – though after much checking all the render settings are set to full quality.
does anyone have experience in working in large custom sequence sizes? can anyone think whats going on with the sequence seemingly losing render files during export? and any ideas on why the QT movies looks crappy?
thanks

I’m curious about the “super-wide” projection. What kind of machines playback this huge sequence, anyway?

Which codec are you using? Animation at custom size?[nevo] “the third issue is that the quality of the final quicktime movie is poor – looks like its been rendered to medium or preview quality”
OH…you probably just need to enable the High Quality viewing option in QT. In QT, type CMD + J > Video Quality > High Quality. Try that.
I have experience with oversized sequences, but I usually use them to pan/scan them through an SD frame.

hey kevin
thanks for the response.
to answer your question on what monster machines can playout this huge sequence the answer is – dataton’s ‘watchout’ display software. it creates any sized canvas you want – each software key you add to your system allows you to control an individual screen.
we create place 3 screens side by side to create a 2160×576 canvas workspace in watchout. you simply drop the quicktime movie encoded to Mpeg 2 of your fcp 2160×576 sequence on the canvas in the watchout display interface and then that is replicated on your chosen display option – plasmas, LCDs or projection.
it’s a pretty cool system and works well for us you can check out a pic on our website at http://www.hillsong.co.uk – scroll down to the bottom of the page, there is a 5 picture slideshow one of the pictures is a wideshot of our stage set up.
the codec we are using is dv pal at custom size – what would be the benefit of using the animation codec?
i will try the command J option in quicktime pro tomorrow.
the whole oversized sequence thing is a bit taxing on the old brain at times…4:3 seems so much easier!!
