Before you start: note exactly what happens
Wondershare's feedback article asks you to record a short video or take a screenshot of the problem before submitting it. [11] Do that first: the exact wording of the error, the percentage where the progress bar stops and the export format are what separate the causes below.
Wondershare does not publish one master 'export failed' article. The steps below are assembled, in order, from its separate support and user-guide pages. Where Wondershare documents nothing for a cause, such as a corrupted project file, this guide says so instead of guessing.
| What you see | Start at step |
|---|---|
| Warning that cloud storage is full | 1 |
| Export finishes but file is missing or in the wrong place | 2 |
| Export stops partway or the app freezes during export | 3, then 4 |
| Red exclamation marks on clips | 5 |
| Content missing from the exported video | 6 |
| Nothing above applies | 7, then 8 |
Steps 1 and 2: cloud backup and the save location
Step 1. If export shows 'Cloud storage is full', Wondershare says the backup option is trying to upload a copy to Filmora Cloud while exporting to your device. Untick the cloud backup box and export again, or free up cloud space. The message relates only to the cloud backup and does not affect local export. [1]
Step 2. In the export window, the user guide says you can rename the video and change the location where it is saved, and tells you to check the output resolution, frame rate, size and duration before exporting. [2] Choose a folder on an internal drive you know has room. Filmora's specifications ask for at least 10 GB of free space just for installation, so a nearly full system drive is worth ruling out. [6]
Step 3: hardware acceleration and format
Filmora has two related switches. In File > Preference, Performance tab, the GPU section has 'Enable Hardware Acceleration for video rendering and playback' and an optional hardware decoding checkbox. [4] In the export window, Wondershare says some formats do not support hardware acceleration, recommends MP4, and notes that the Hardware Acceleration option and Advanced Compression cannot be enabled at the same time. [3]
Wondershare does not publish a rule for which setting fixes a failed export, so treat this as a controlled test: export to MP4 with Advanced Compression off, once with hardware acceleration on and once with it off, and note which works.
Step 4: update the graphics driver
Wondershare's GPU article identifies the card with the DirectX Diagnostic Tool (type dxdiag in Start search, then open the Display tab) and links driver downloads from NVIDIA, AMD and Intel, recommending the most recent version. Laptop owners should get drivers from the laptop maker's website. [5]
Check your hardware against the published minimums at the same time: Windows needs at least 8 GB of RAM (16 GB recommended for HD and 4K) and a GPU such as an NVIDIA GeForce GTX 1050 Ti or Intel UHD Graphics 630 with 2 GB of VRAM, with 4 GB of VRAM recommended for HD and 4K. [6]
Steps 5 and 6: problem clips and the timeline
Step 5. A red exclamation mark on a clip means its source file was moved or deleted. Click the mark or the prompt, browse to the original file and select it to relink. [7] Also check formats: Filmora's specifications list MKV import only when encoded with MPEG-4 or MJPEG, so an MKV recording in another codec is a candidate for trouble. [6] Converting such files to MP4 before importing is our suggestion, not a Wondershare instruction.
Step 6. If content is missing from the export, Wondershare says to confirm the correct project was saved and opened, and to switch back from a compound clip or sub-timeline to the main timeline. [8] If the render preview button is greyed out, a green line above the timeline means rendering is already complete; a red line with an unclickable button should be reported through Help > Feedback. [9]
Wondershare has no support article on corrupted project files among those we read. If a project fails every step, rebuilding a short test project from the same media helps tell a project problem from a media problem.
Step 7: update Filmora
The export guide carries a banner advising the latest version for best results, [2] and the pricing FAQ says you update by downloading from the Free Download button on the Filmora official website. [12] Update before contacting support; it is the first thing a ticket is likely to ask about.
Step 8: what to send Wondershare support
Wondershare documents two routes. Help > Fetch Log opens the log folder, which you compress whole and attach. Help > Feedback lets you describe the problem with logs attached automatically, which Wondershare recommends. [10] In the feedback form, choose the issue type, upload your video or screenshots, describe the steps you took and any warning messages, and check your email address is correct or support cannot reply. [11]
- Filmora version and operating system.
- Export format, resolution and frame rate, and whether hardware acceleration was on. [2][3]
- The percentage or timecode where export stops.
- Screen recording or screenshots of the error. [11]
- Log folder zip, or submit through Help > Feedback so logs attach automatically. [10]
- Your order number if the issue is linked to licence or watermark status.
Questions before you decide
Does 'Cloud storage is full' mean my Filmora export failed?
Not the local file. Wondershare says the message relates only to the cloud backup copy; untick cloud backup in the export settings or free cloud space, and local export to your device is unaffected.
Where is hardware acceleration in Filmora?
Wondershare's guide puts it under File > Preference, Performance tab, GPU section. In the export window the option only appears for supported formats such as MP4 and is hidden while Advanced Compression is on.
What should I send Filmora support about a failed export?
Use Help > Feedback, which attaches logs automatically, or Help > Fetch Log and zip the folder. Include a screen recording or screenshots, the steps you took, any warning text and a correct email address.
Can Filmora import OBS MKV recordings?
Filmora's technical specifications list MKV import only when encoded with MPEG-4 or MJPEG. Check your recording's codec, and consider remuxing or converting to MP4 before importing.
