How to Avoid Overwriting Clips When Rendering Output Media
Three of the options described previously, “Use unique filenames,” “Place clips in separate folders,” and “Use commercial workflow,” are all ways of organizing your rendered media to avoid overwriting rendered clips that happen to share the same file name. These options are necessary because each clip has one logical range of timecode, and because multiple clips often refer to a single source media file with one name.
When rendering a clip, DaVinci Resolve automatically overwrites any other media files that have the same name. So, in instances where you’re trying to preserve the previous filename of the source media file, or where you’re rendering out multiple versions of the same clip, it’s entirely likely that the clips you’re trying to output will overwrite one another, leaving you with the last clip you rendered.
The three options mentioned previously prevent this in different ways.
Defining a Range of Clips and Versions to Render
Once you’ve defined the Render Settings, now you need to decide how much of the Timeline you need to render. A Mini-Timeline and Thumbnail timeline are available to help you navigate your project’s clips in order to choose which ones you want to render. Track controls let you enable and disable whole tracks from being output; for example if you need to render a textless version of a timeline in which all the title clips are on track V4, you can disable track V4. Furthermore, you can also use these controls to choose which clip versions you want to render.
— Choose Entire Timeline from the Render drop-down in the Deliver page timeline. This option only appears if clips are not filtered.
— Click the Video or Audio Disable Track button for the tracks you want to exclude.
1 Open the Color timeline, if it’s not already shown, and choose an option from the Timeline Filter drop-down to the right of the Clips button in the Interface toolbar.
The contents of the Thumbnail timeline are restricted to show only the clips matching the selected criteria. For example, if you’ve already rendered a session, but you’ve since made some changes, you can use one of the “Show Modified Clips” options to display only the clips that have changed within a particular timeframe. Another possibility is to choose the “Show Unrendered Clips” option to show all clips that have not yet been rendered.
2 Choose “All Filtered Clips” from the Render drop-down in the Timeline toolbar.
Choose All Clips from the Timeline Filter drop-down to the right of the Clips button in the Interface toolbar.
