Why Is Adobe Rush Slow at Rendering? – Fixes and Causes
Adobe Premiere Rush CC is an all-in-one video editing tool which provides basic video editing (when compared to the more advanced Adobe Premiere Pro). Like any video editor, video on Adobe Premiere Rush may sometimes render slow. In fact, a computer not set up correctly may not render the video at all or crash the system. You may ask “how do I speed up rendering?” Fortunately, Premiere Rush can render at faster rates when optimized changes are made to your hardware and software.
Consider Upgrading and Optimizing Your Hardware
Your computer hardware will determine the limitations of your rendering speed, with the CPU and available RAM being especially important. Hardware that is not ideal can be optimized to run at peak capacity as long as Adobe’s system requirements are met.
Meet the Minimum Requirements
Adobe Rush will not render well if the software minimum requirements are not met, as shown in the table:
|Minimum Requirements for Windows|
|Operating System||Windows 10 – version 1709 or newer|
|Processor||64-bit capable multicore CPU|
|Sound Card||Windows or ASIO protocol compatible|
|Hard Drive||8GB Hard-Disk|
|Device Driver||Intel Graphics Driver|
|Internet||Needed for subscription, registration and software activation|
|Resolution||1280×800 display or larger|
|Misc.||GPU for faster performance|
Note: The CPU, hard drive, and GPU tend to be the most common cause of why rendering is taking so long. Most slow performing hardware can be optimized to perform renderings more quickly.
If Your CPU Is Overloaded, Optimize It
Rendering is a CPU-intensive process that performs better by having a multicore CPU with a high clock rate. If you have a slower CPU, consider reducing the number of applications that run at start-up. Here’s how:
- At the Start menu, search for Task Manager or press Ctrl-Alt-Dlt
- Click the Startup Tab
- Disable all the programs possible from your system Startup
- Restart Your computer
Note: Instead of Processing Power, inactive applications often use more RAM. Click the task manager Processing tab to get a feel for the applications that are using more processing power.
Your Hard Drive Might Be Slowing You Down
If your render rate is still slow, you might consider upgrading your hard drive. It takes time for your computer to access and transfer data, and a slow drive will significantly reduce your render speed. A Solid-State Drive (SSD) has no moving parts and can access data the quickest. A second option, RAID arrays, are second to best and use multiple hard drives to retrieve and store different sections of the same file, which allows them to pull data more quickly.
If you are working with one drive, and it is not solid state, defragmenting your hard drive would probably be best for higher transfer gains. Disk Defragmentation pulls system files to the same area for faster retrieval. Here’s how to defragment your hard drive:
- Search Start for Defragment and Optimize Drives
- Select Optimize and your computer will begin performing the defragmentation process
Note: On the same menu, your Defragger can be scheduled to run automatically.
Your GPU Can Play a Factor
The GPU (Graphics Processing Unit) can assist the CPU and result in faster render times. The GPU will only process events it can handle, such as scaling (discussed in a section ahead), video rotations, or any other video effect that requires graphics processing. To get the most use from your GPU, its best to make sure that Drivers are updated (next section).
Update and Reinstall Your Drivers
In Premier Rush, outdated drivers are known to cause strange rendering issues like blurry green, pink lines, and yellow screens. We recommend automatic driver updates, to have your drivers processing data correctly or you can upgrade your drivers manually as well. Here’s how to update your drivers:
- From the Start menu, search for Device Manager -> Click Device Manager
- From the menu items, select Display adapters, then select your audio device
- Right-Click tab and select Update Driver
- Click Search automatically for updated driver software and follow the prompts
Note: Windows will not always grab the most updated drivers available. Sometimes it’s best to check the manufacturer’s website for more driver options or use specialized software to automatically get your driver updates.
Use software techniques to render videos more quickly. The goal is to reduce computer calculations, so that rendering speed improves. Media imported to Adobe Rush should closely resemble the format of your planned video to increase render speed. Common items affecting render times are frame rates, effects, and scale.
Scale Your Video Correctly
The sequence of clips will render more quickly when it’s scaled to the same size. Do this by:
- Select the Crop and Rotate icon from your left pane navigation bar.
- Scroll to Scale to adjust the Width and Height of the video. Scale your clips to the same size as the final video for the fastest render times.
Minimize Special Effects
Special effects will also increase the time taken to render a video. Special effects can include transitions, color effects, and third-party effects. Some examples are:
- Transition effects: These are the top 3 transition effects available on Adobe Rush.
- Color Effects: These are the top 4 color effects available on Adobe Rush.
- Title Effects: These are text effects that can be added to annotate Transitions within your video.
Tip: Save time on rendering effects by transcoding the video with the effect already added to it before importing to Adobe Rush.
Adjust the Frame rate
The frame rate of your video clip sequences should match the frame rate of the video that is being exported. Variable rate footage such as gameplay, webcams, and mobile applications should be uploaded to Adobe rush at the same frame rate to increase rendering speed. The output rendering speed is selected by:
- From the Adobe Rush home submenu, select
- From the Frame Rate submenu, select your targeted frame rate.
Tip: When in doubt, use the automatic frame rate.
Use Smart Rendering
Smart rendering can drastically cut down render time by processing more data up front. Here’s how:
- From the navigation toolbar, select Edit -> Preferences
- Checkmark Pre-render sequences for playback and select OK
Let’s Make Sure Adobe Rendering Stays Quick
After troubleshooting and optimizing your hardware and software, you may find that Adobe Premier Rush renders a bit faster, even with dated hardware. Just remember, if Rush starts to render slowly, be sure to verify that other programs are not in use. Adjust your software and media settings to keep rendering fast and keep driver updates in mind. Your outdated drivers can affect the render speed and should be updated regularly.
To save yourself a hassle and quickly render videos, we recommend Driver Support for all of your video driver needs. Driver Support automatically updates drivers to their most recent versions, so you can spend more time making videos and less time troubleshooting.
