Premiere pro why render

Are you experiencing some strange playback issues or seeing an array of coloured lines above your timeline? Rendering is a workflow that allows you to playback at full speed and quality but it does take a little time to do. Select an area of your timeline you would like to render, either via the in and out shortcuts or by dragging a selection box around the area.

Alternatively you can hit Return on your keyboard to render any effects in the timeline straight away. This is what makes Premiere such a quick editing program to get started with. You can throw anything onto the timeline, from anywhere on your computer and get editing. This helps keep project file sizes small and manageable but the downside is that Premiere Pro is then very much dependent on your computers hardware specs and the media type you have given it to use rather than its own codec it knows it can playback properly.

This is where we start to see lagging during playback. When you start adding effects and transitions into the mix then Premiere Pro can have a difficult time keeping up with the task of playing back in real time. Rendering part or all of your timeline means that Premiere Pro will go and export a version of that clip or timeline in the background for its own use in playback. This is called a Preview file. When Premiere has rendered a preview file it will use this new file to playback with rather than referencing the original media file and un-rendered effects.

It will play this version of the clip every time thereafter so long as no changes are made to that clip, nest or adjustment layers. If changes are made Premiere will need to re-render to create a new Preview file. You will have noticed when adding a clip to the timeline that sometimes Premiere Pro will show a yellow or red line above it on the timeline.

Sometimes there may be no coloured line at all and then other times there will also be a green line there. When there is no color above a clip in the timeline it means that there is no rendered preview file that Premiere Pro is referencing but that the media type, codec or resolution is simple enough for Premiere to playback without rendering.

The better the hardware specs of your system the more often you will see no coloured lines above your timeline. The area in red is either a file format that is harder to playback, is a large resolution, has had a complex effect applied or multiple effects applied to it.

Green then, is when Premiere Pro has rendered a preview file and is going to use that file to reference while playing that section of the timeline. Rendering is a habit that you should really start getting used to as an editor. If you're editing a DV project, you can preview the sequence on a television monitor via your IEEE connection and camcorder or video deck.

Set these, instead, to DV or Auto mode. Desktop Video Display During Playback. Specifies whether or not to play back to the Program Monitor. Deselect this option to play back only through the external monitor specified in the External Device option. External Device. Aspect Ratio Conversion. Desktop Audio. External Device Audio. Export: External Device. Enables export to tape for the specified device. This option doesn't affect playback to an external device during export.

Disables video to the external monitor if Premiere Pro is not the active application on your desktop. Specifies the conversion method for 24p footage. See Set 24p playback options. If the video and audio seem out of sync, try to preview both video and audio through the same device. Adobe video applications can automatically insert a unique document ID into each imported file. These unique IDs ensure that each application accesses the same cached previews and conformed audio files, preventing additional rendering and conforming.

This setting is global—a change in one Adobe video application affects all the others. This setting also results in new file modification dates when IDs are initially inserted. To save rendering time when transferring a project to another computer, move both cached and original files. Legal Notices Online Privacy Policy. Buy now. Rendering and previewing sequences Search. In this Help article, learn how to render, preview, and playback sequences in Premiere Pro. Define the work area for rendering.

Do any of the following:. Define the area for rendering using In and Out points. You can mark In and Out points to define an area for rendering:. Mark In and Out points for the area of the sequence that you plan to render. Render a preview file for a section of a sequence. Render a preview file for a section of a sequence setting In and Out points:. Set In and Out points to mark the area you want to preview. Choose Sequence, and select one of the following:. Renders a preview file for the sections of the audio tracks lying within the work area.

The rendering time depends on your system resources and the complexity of the segment. These options are not available if the work area is enabled. Render audio when rendering video. Click OK. Work with preview files. When completely done with a project, delete preview files to save disk space. Use preview files when rendering.

This will mostly be handled by the video card GPU especially during rendering, which makes it an important piece of building the best high-speed video editing computer you can. The developer of Eevee recommended as much vRAM as possible. A: Redshift is a fully GPU-based rendering engine. This means that the video cards or GPUs in your system are what impacts how long renders take to complete, rather than the CPU.

But keep in mind that GPU rendering is only efficient with 2d applications. As such, there is no way to get a true apples-to-apples comparison of these two types of hardware. In other words there is a synergistic balancing act between those two processors and the motherboard RAM. The CPU needs to have a good clock speed to support the graphics card, so numbers of cores and multi-threading and performance are not that important.

So in terms of the graphics cards, clearly the GTX is preferred. RTX support for our other V-Ray products is in the works.
