Exporting a 2K sequence to DVD from FCP
Hi all, merry Christmas!
I’m new here and I hope I’m posting this in the right forum. I have just finished editing my 40 min short film shot on a SI-2K mini and I’m having huge problems exporting the movie, which is on an external 2TB harddrive. I’ve tried both compressor, quicktime conversion and quicktime movie, but since the former two caused my system to crash on every occasion, and since I found out that a quicktime reference movie is virtually lossless, I have a 450 MB sequence on my drive now.
The thing is, when I put this sequence into compressor to make a DVD (MPEG-2 file), it exports OK but the end result is completely PURPLE! I don’t know why, but I’ve tried three times now and every export turns completely purple. I have numerous titles (text) and a graphic (logo) running throughout the whole sequence in FCP because this DVD is a screener. I know I could make a watermark in DVD studio pro, but since I can only have one stream open at a time, I just opted to put everything of warning messages etc. hardcoded on the video.
Does this problem have something to do with the 10-bit YUV rendering? Is it because I don’t have a fully eligible (trial only) version of the Cineform codec? I need to know fast because I need to send this DVD to my tutor who’s across the Atlantic and time is vital.
All help appriciated!
Thanks!

Hi Sutharsan,
I would recommend you to the conversion in two steps.
First downscale your 2K movie to a SD QT movie. Then compress to MPG-2.

Thanks Rafael – I am trying to do the conversion in 2 steps, but the first step is the problematic one because the image turns purple through compressor (the mpeg-2 file) – even when I first do an SD (DV-Pal) conversion. I don’t understand why? I’m pretty sure though, that it must have something to do with the 10-bit rendering in YUV or something?

Hi Sutharsan,
You have a nice 2K picture in 10b. Don’t go to DV.
Put your 2K sequence in a SD sequence with the same tame base. Set 10b Unc or Proress as the codec and in Rendering Motion Effects: BEST.
Get a good quality SD master then the MPG-2 will be easy.

I tried to put the video rendering option to “render all YUV in high quality” and I put motion estimation to “best”. It took me 14 hours to render the whole film, the result was OK. I made a Quicktime reference movie which also worked fine. Then I opened up compressor and chose “DVD best quality 90 min” – the result is again purple. I don’t know what to do?
By telling me to put the time line in an SD sequence, do you mean I have to create a new sequence with SD settings? These would be 700x something by 576? And then render the whole project again using “high precision YUV” ? And then making a QT movie and then export via Compressor?
If I make a “self-contained” QT movie (which will probably take as long time as to render the whole film again) isn’t that better? Then I send that to compressor, will that solve my “purple” problems?
Thanks for your help!

Hi Sutharsan,
I don’t like working with reference movies.[Sutharsan Bala] “By telling me to put the time line in an SD sequence, do you mean I have to create a new sequence with SD settings? These would be 700x something by 576? And then render the whole project again using “high precision YUV” ? And then making a QT movie and then export via Compressor? “
If you have your 2K al ready rendered in FC, drop it in a SD sequence and render in High Precision, etc.
FC makes the downscaling faster than Compressor with no less quality.
If you go to a PAL DVD the size must be 720×576.
This is other good reason to do the downscaling in FC because going from 2k to SD (4×3 or 16×9) you have to resize and crop. To do that in FC is much easier
In the end you will have a high quality PAL master that you can play in any external monitor. If it works fine, you only need to transcode to MPG-2.

Thansk! I used the Prores codec and it looks quite nice! Don’t know if it’s the BEST quality but I’m happy for now. Thanks for your input! – and Happy New Year!
