Rendering & Troubleshooting

Once you’ve finished editing, rendering compiles everything into a final downloadable video file. This page also covers the most common editor issues and how to fix them.

Rendering your video

When you’re satisfied with your edits, click Render Video in the editor. VidRush compiles all layers like visuals, narration, music, captions, animations, and transitions into a single video file.

Always save before rendering. While Auto-Save captures most changes, it’s good practice to confirm everything is saved before you commit to a render.

Re-rendering costs credits.

File naming: Rendered files use your Project Title as the filename.

Magic Reset

If you’ve made too many changes and want to start fresh, click Reset Timeline in the editor settings. This reverts the entire project to the initial AI-generated state, removing all manual edits. Your edit history is preserved in the History tab if you need to reference anything.

Common issues and fixes

Editor is buffering or freezing

This sometimes happens with longer projects (30+ min) or on slower connections.

• Refresh the page, Auto-Save preserves your work.
• Try Microsoft Edge instead of Chrome. Some users report better editor performance.
• Close the tab entirely and reopen the project from Projects.

Video won’t render or gets stuck

Usually caused by a “ghost clip”, an empty section on the timeline where no image or video is assigned.

1. Scroll through your timeline and look for any visual blocks that appear empty.
2. Delete the empty block.
3. Try rendering again. This resolves the issue in most cases.

Audio glitches in the preview

Slurring, cutting out, or garbled audio in the editor preview is almost always a browser buffering issue. It is not a permanent error in your video.

The fix: Click Render Video. Approximately 90% of preview audio glitches resolve automatically in the final rendered file. Always render before reporting an audio bug.

Can’t select small clips on the timeline

Zoom in. Use Ctrl + Mouse Wheel or the Zoom slider in the right panel to expand the timeline view for precision editing.

Voiceover quality drops mid-video

This is often a pre-render artifact. Render the video and check the final file. If the issue persists in the rendered output, report the Video ID to support through the Crisp chat widget.

Download is slow or filename looks wrong

Filenames are based on your Project Title. If the download hangs, refresh the page, your latest render is saved and won’t be lost. The download link remains available in the project.

My video suddenly looks plain or low quality, or things seem missing

Check your Brand Profile, Creative Assets first. Disabled animations, overlays, effects, or individual motion graphics and transitions are simply left out of the generation, which often reads as “low quality.” Re-enable what you turned off and generate again. This is the most common cause of a sudden quality drop.

Footage looks generic, repetitive, or no longer matches the narration

Check your Brand Profile, Compliance blacklist. Every blacklisted source shrinks the footage pool, and a long blacklist (or one that blocks major sources) leaves the footage agent with too little to work from, so it falls back to generic stock. Trim the blacklist.

Editor is slow on my machine

The new UI can be heavier on older or slower devices. Try Edge, close other tabs, and reduce timeline zoom. If it stays unusable, report it to support, ideally with a screen recording (via jam.dev) so the dev team can pinpoint the performance issue.
