re-rendering a quicktime, instead of re-rendering an entire comp?
hello – – I have just rendered a 5 minute quicktime movie that took 43 hours to render. I now have changes to make to my original comp, however it is only at the very end of the comp (credits).
I was hoping that rather than render out the entire comp again that took 43 hours, that i could import the quicktime and match it up to the frames at the end that needed to be changed and that perhaps it may speed up the rendering process?
I don’t want to loose quality and not sure if by re-rendering a quicktime will infact loose quality or if it will even speed the process?
Any light on this issue would be a great help!
Thanks

the loss of quality depends on the codec you used to render the qt. this is why I always render things that will take a long time to render using animation at best. this is a losless codec and doing what you suggest will not change any of the pixels. sometimes you can get away with rerendering dv footage once or twice before it starts to fall apart

Can you just render the credits in AE, then join the two clips together in an editing application, in a timeline that uses your codec so there’s no recompression?

You can also copy-paste the new movie over or behind your existing render in Quicktime Player if you have Pro,
this way, you can even mix different codecs if you want.
Be sure to save the new version as a self-contained movie
I use the editing facilities of Quicktime Pro all the time, you can even do compositing of multiple layers that have alpha’s etc.
