When a change is made in the Timeline, that render file is no longer valid, is ignored, and a new render file would need to be written. It is only to make playback easier, that's it. Please explain Rendering 03 Aug Thank you everyone for all your posts - I now have a much better understanding about rendering.
My conclusion for best workflow is to switch off bg rendering - especially during the titles making process etc so as not to over work computer - then once I'm done render all and upload Please explain Rendering 04 Aug How to resolve AdBlock issue?

Posts: Karma: Thank you received: Don't bother to render and export Upload in two separate steps at this point, just export, that step renders as part of the export process. As BenB points out, render is only to make timeline playback easier. Since you'd be done editing, just let FCPX finish your export with one step.
Rendering is the process of converting a software model to a 2D or 3D image. When you invoke an effect that is a mathematical transformation that must be applied to every frame of the clip. Even though producing render files is a common practice, it is really unrelated to disks and caches since it could be entirely buffered in memory.
We often use the term loosely such as "render it out". If the timeline is not rendered, then exporting may require rendering as one phase but they are distinct actions.
Premiere is very good at using the GPU for accelerated rendering of effects. This is indicated in the timeline by a yellow bar which means GPU rendered. Since FCP X doesn't use that color coding it is tempting to say it's more dependent on background rendering.
However if you just turn off background rendering in FCP X it does pretty well. I thought that the more compressed files — such as ProRes LT — would render more quickly than larger formats.
In fact, every time I ran these tests, rendering took a different amount of time! This points out a key fact: render speed is dependent on what else your computer is doing at the time. The first time I ran this test, they were within eight seconds of each other.
Then, choose Delete Render Files. FCP will simply recreate them. I found this exercise fascinating, because the results were not what I expected. If you have plenty of storage space, render in whatever codec you prefer. If storage space is tight, render in ProRes or LT. All that work by you for so little diff in results! And thanks for the additional notes about getting rid of unneeded Render files. I use an iMac, 6 core, 3. There is not much else running in the b. Is there a preference setting or cache setting somewhere that may need expanding, or.
Thanks so much for your response. Your videos have been my go-to answers for several years now. Gratefully appreciated. Running Compressor 4. Is there a way to set up virtual clusters with the new Compressor to improve on this? I also noticed that H encoding exports are drastically improved if I need to do them in Compressor not typical but nice to know vs just exporting it in Final Cut X.

No worries, if it needs to render new files, FCP will recreate the folder Reply.
Thierry: While you are correct, I try to avoid going into the Library from the Finder. Larry Reply. Bill: I agree totally. Another keeper! Thank you Larry Reply. If you want to free up storage space, you can delete unused render files in selected events.
You can also delete all render files for projects, events, or libraries. Original media files are not deleted, so you can always regenerate render files from the original media. Note: The Delete Generated Files commands delete render, optimized, and proxy files only. See Create optimized and proxy files in Final Cut Pro. Note: The selection must be a clip selection, not a range selection.
