How to Fix DaVinci Resolve Render Job Failed?

DaVinci Resolve can play a timeline normally, then stop the export with a Render job 1 failed message. The line underneath matters more than the job number: it identifies what Resolve could not process.

Playback can use proxies or cached frames that hide a problem with the originals. Export also requires Resolve to process the effects and write the output file.

1. Test the Failed Section, Not the Whole Timeline

The reported timecode identifies the frame. A percentage is only a rough location guide, especially for multi-output jobs.

1. Save and export a .drp copy through File > Export Project. It does not include source media.
2. Copy the full error and timecode. If only a percentage appears, watch the Deliver preview during the retry to locate the section.

   

3. In the Media Pool, right-click the timeline and select Duplicate Timeline. On the copy, mark a few seconds before and after the failure with I and O.
4. On Deliver, choose In/Out Range, keep the original export settings, and Add to Render Queue.

   

If the range fails, test one affected clip or effect at a time. If it passes, widen the range; a short success does not rule out a longer-render problem.

2. Check the Output Folder and Available Space

Even with room for the export, a full cache or temporary-files drive can stop the job. Check both locations.

1. In Deliver’s Render Settings, click Browse beside Location. Test a writable local folder outside cloud-sync folders.

   

2. Use a new output name, such as render-test-01, without overwriting an earlier export.
3. Check free space on both drives and that you can create a small file in the destination. Intermediate files can be much larger than MP4 exports.
4. Add a new job and retry the same range.

If an external drive is FAT32, its single-file limit is about 4 GB. Use another suitable drive; do not reformat a drive containing your footage.

If the local test works, check the original destination’s access and connection. External drives are not inherently unsupported.

3. Test Without Render Cache, Proxies or Optimized Media

A cached frame can fail after the underlying clip has been corrected. Test with the originals online; disabling proxies cannot recover missing source files.

Record the existing cache and media switches before changing them.

1. Choose Playback > Render Cache > None to stop background caching.
   
2. Choose Playback > Delete Render Cache > Selected Clips for suspect clips, or All for this project’s cache.

   

3. In Deliver’s Video Advanced Settings, uncheck Use render cached images. Also uncheck Use proxy media and Use optimized media for this comparison.
   

Delete only through the cache menu, not your media folders. Resolve will need to rebuild deleted cache. Leave the unrelated Force sizing/debayer controls shown above unchanged.

If the test still fails, restore your earlier settings. Otherwise, rebuild any editing cache before relying on it again.

4. Test Another Export Codec or Encoder

Changing MP4 to MOV changes the container, not necessarily the codec or encoder. Test those choices separately.

1. Choose Custom Export > Video. For an intermediate test, select Format: QuickTime and Codec: DNxHR, or ProRes if supported.
2. Keep the required resolution and frame rate. Choose a profile that preserves the footage’s bit depth and transparency where needed.

   

The image above shows Adobe Media Encoder. Use Resolve’s Deliver controls instead.

Check the Encode column in Blackmagic’s codec list for your installed version, OS and Free/Studio edition. Your edition’s resolution and frame-rate limits also apply.

For H.264 or H.265 Encoder Errors

If offered, compare Encoder: Native with the named NVIDIA, AMD or Intel encoder. The screenshot still has Auto selected; Auto can choose hardware. Native is not a guarantee of CPU-only processing on every platform.

Add a new job after changes. If the intermediate works, encode the delivery copy from it. Preserve required colour, audio and quality; an 8-bit test cannot replace a required HDR master.

5. Reduce GPU Load and Check the Driver

Heavy effects can exhaust GPU memory. Changing the encoder does not remove GPU processing for grading or Fusion.

1. Save, restart once, and close other GPU-heavy applications. Return any manual GPU tuning to stock for comparison.
2. Open DaVinci Resolve > Preferences > System > Memory and GPU. On a hybrid PC, check that the intended supported GPU is selected; save and restart after changes.

   

3. On Windows, use a compatible driver from your manufacturer, NVIDIA or AMD. NVIDIA Studio drivers target creative applications. Mac graphics updates come through macOS.

The pictured Apple Silicon Mac uses unified memory. It does not need a separate graphics card, and the RAM sliders do not add GPU memory.

For moving failures, optionally lower Deliver > Render Settings > File > Render Speed below Maximum. This changes processing speed, not frame rate; an oversized effect may still exceed available memory.

If the range still fails with Error Code 5, check the specific GPU image-processing settings. A memory-full message instead calls for reducing the affected effect’s workload.

6. Isolate Heavy Effects Before Using Render in Place

For a named Fusion or Text+ failure, isolate that item rather than removing effects throughout the project.

1. On the duplicate timeline, bypass one suspect effect, title or transition and render the same range. Restore each ineffective change.
2. If that identifies the failing item, simplify or rebuild it. Right-click a suitable timeline clip and choose Render in Place for a separate intermediate render.

   

3. Choose DNxHR or supported ProRes at suitable quality. Include the required video, Fusion and colour effects, plus handles for transitions; select a writable folder.

Render in Place still processes the effects. If it fails too, repair the effect or source. Decompose to Original restores editable effects.

If Render in Place works, check the new clip’s frames, colour and transitions before export. Keep its rendered file while the timeline uses it.

7. Check and Repair the Failing Source Clip

A proxy can play without its original. A decoding error may also affect one recording while other clips with the same extension work.

1. Right-click the named Media Pool clip and choose Reveal in Media Storage or Finder/Explorer. Confirm the original is fully available, not a cloud placeholder.
2. Reconnect its drive or copy the source locally. For a moved file, use Relink Selected Clips; the Resolve media-access and format checks explain these controls.
3. Inspect the recording with MediaInfo; another player’s playback does not guarantee Resolve compatibility.

   

4. If the complete clip can be decoded, make a separate DNxHR or supported ProRes copy. Shutter Encoder’s documentation covers those conversions; use constant frame rate for a confirmed variable-frame-rate recording.
5. Import the copy into the Media Pool. Replace only the affected segment on the duplicate timeline, using the original source In/Out points.

Keep the original. Test the converted clip on the duplicate timeline, matching duration, source timecode, edit positions, colour and audio sync.

If the converter still fails to decode a frame, re-copy the recording or use a verified backup. Conversion cannot reconstruct missing frames.

8. Check Audio Without Changing the Required Mix

Fairlight or audio-plugin processing can stop a job even when the video looks correct.

1. In Deliver > Audio, temporarily uncheck Export Audio for a diagnostic range only. If video-only works, investigate the audio rather than delivering a silent file.
2. Re-enable audio. Check the intended output bus and supported codec: AAC for a compatible MP4, or PCM for an intermediate MOV.

   

3. Bypass suspect clip or bus audio effects individually and retry. Reconnect missing audio or test a clean PCM WAV copy of the affected source.

Linux AAC support differs; use the codec list for your version. Restore all required channels and effects, then check sync and the complete mix. Headphone or speaker routing is not the export bus.

If audio still fails after the video-only test works, include the affected bus, plugin and audio format in your support report.

9. Test a Fresh Timeline or Project

If checked media and effects still fail in one timeline, try a small section in a fresh timeline.

1. Create an empty timeline with matching frame rate, resolution and colour settings. Copy only the suspect section and retry the same export settings.
2. If necessary, copy the section and open Project Manager (house icon). Create a separate test project with a matching empty timeline, then paste the section.

   

Keep the original project. Importing its .drp restores that project, not a clean rebuild. Copying an edit may carry the faulty effect; project-level audio and colour settings can also differ.

If the test works, transfer and check additional sections before adopting it. Compare grades, titles, transitions and the mix; success alone does not prove timeline corruption.

Before the Final Export

Restore Entire Timeline, required resolution, frame rate, audio and quality settings. Keep error checking on. Watch the repaired sections and verify the finished file’s duration, titles, colour, channels and sync before delivery.

If the same error returns, send the diagnostics and failed-job settings to support instead of repeating a full render.
