Hi all maclovers,hehe!
I was editing my HDV footage in FCP 6 and had terrible problems exporting. Basically it was impossible exporting the rendered sequence in any codec + exporting times flew up in the roof.
I posted around at different FCP forums but no answers. I experimented a lot and came up with a solution to what I realise now is a FCP 6.01 and 6.02 bug.
Here's a big warning for those of you editing HDV footage in FCP 6 in HDV native form:
When editing HDV material in an HDV sequence you get the choice of changing your rendering settings to Prores within the HDV sequence (Not the same thing as having a Prores sequence).
Why you would do this is because if you render as HDV, rendering times are much longer and this option permits you to work faster. So far all is well.
The problem arises once you have finished your editing and want to export it:
If you then have your whole timeline rendered with option to render as Prores and now try to export selfcontained file or reference file your exporting times go bonkers: 8hours for my 35min sequence.
Why? Because it doesn't just export referencing renderfiles but starts recompressing the whole thing once again.
Solution:
What you should do is this:
Edit HDV in HDV timeline with option render to Prores ticked. Now, once you are completely finished editing delete your Prores-rederfiles (use rendermanager).
You have now two options:
1 Rerender your hole timeline as HDV (change your rendering option to same as sequence codec).
This time rendering will of course take a while. But once your rendering is done and you try to export, exporting times go down to 5min for selfcontained and 2min for reference (on my system).
2. Your second option is to change your sequence settings or drop your edited clips into a Prores sequence. Rerender sequence again. And this time exporting times will be very short as well. Though maybe a bit longer since files are now bigger.
EXPLANATION:
I asume by all this that the Prores-rendering option in an HDV sequence is only a meant as a temporary-while-editing solution by apple to help you work on your editing much faster than if you had to render to HDV while you were editing. It is not intended that you export a sequence from these renderfiles and therefore problems arise when you try.
I hope this can help those of you that have had problems exporting.
P.S. When doing your final render it's very important that you have all your rendering options ticked: even FULL render. Otherwise, when exporting you will not only be exporting but compressing.
If you have any questions please post quickly as I will be off on a nice vacation for a few weeks.
