Re-render everything after trimming the clip??
Posted: Mon Aug 19, 2013 11:55 pm
Hi there:
I am working on a project which has about 45min clip to go. I firstly applied NeatVideo to denoise, the render time took about 20 hours (meh, I am using my macbook pro retina, don't blame me). After that I tried to apply some subtitles and transitions onto the clip, OK it seemed fine, except for the calculation time has been much longer than usual and my computer even lags heavily when editing the text of subtitles while not rendering. These are all the small problems, and there comes a big one.
I then have seen that my video needs to be trimmed for a bit, so I trimmed the end of it, shortened it for a few seconds. The ruler on the timeline immediately turned fully amber indicating that the entire clip needs to be re-rendered, which makes me very surprised. Isn't it supposed to be none since I only have removed a few seconds of frames? I quickly selected to undo it, then it was back to rendered status. I tried the razor tool instead, and the entire clip needs to be rendered again, so I am confused.
And I wonder how the filter works. It looks like if there is a change of the clip, everything needs to be rendered again --- doesn't final cut save the denoised material somewhere, or everything was calculated on the fly?
Now I have learned the drill... do everything else and then apply the denoising filter at the last step before sending it into compressor or youtube. Is this a standard or there's some settings that I don't know?
Thanks... and I am back rendering the clip again...
