Troubleshooting

Start with the two things that fix the most: use the latest Chrome or Edge, and reload the page (Ctrl+R). When the top bar says Saved, a reload loses nothing; if it says Not saved or Not stored, save a project file first (File, Save a project file).

Importing

A video will not import, or shows as unreadable. The browser cannot decode its codec. HEVC (H.265) needs a device and browser that support it; some screen recorders and older cameras use codecs no browser reads. Convert the file to MP4 with H.264 video in another app, then import it again.

An MKV plays without sound. Most MKV sound (including E-AC-3 from TV recordings) is supported. If one still plays silent, convert its sound to AAC.

Import is slow. A long 4K video takes a moment to read and to make its lighter playback copy. You can edit while it works.

Playback

Playback stutters. Make sure Proxy is on under the viewer: playback then uses lighter copies of your videos. Close other heavy tabs. Many effects and VFX at once ask a lot of the graphics card; the export is never affected by stutter in the preview.

The picture is black, or effects do not show. Reload. If it persists, the browser may have lost the graphics card (after the computer slept, for example): restart the browser. Check that hardware acceleration is on in the browser's settings.

Sound

The sound is out of sync. A video recorded with a variable frame rate (phones, screen recordings) can drift. Import it again; if it persists, convert it to a constant frame rate in another app.

No sound at all. Check that the track is not muted (M), that another track is not on solo (S), the clip's Volume in the Audio tab, and the device's volume. Browsers only play sound after you have clicked on the page once.

AI tools

What each model does, how big it is and when it downloads is in AI models on your device.

"The image model could not run." The model did not download completely, or the device could not run it.

• Check your connection and press the tool again: the files already downloaded are kept, and the rest come down.
• Close other tabs to free memory: the larger models need a few hundred megabytes.
• Update the browser and your graphics driver. DriftEdit runs a model in WebAssembly by itself when the graphics card refuses it, but a very old browser may not have what it needs.
• Try Chrome or Edge on a computer if you were on a phone.

An AI tool is slow. Without a graphics card that WebGPU can use, the models run on the processor. They work, more slowly. The first use also includes the download.

Captions from speech got words wrong. Choose the spoken language instead of letting it guess, and make sure the voice is clear: Clean up the voice first helps. Fix the rest under Lines.

Auto mode

The cuts are not on the beat. The tempo was read at half or double, or bar one is off. Under the song in the Auto panel, press Half the tempo, Double the tempo or Bar one at the playhead, then make the edit again. You can also drag kicks on the beats row to where they really are; the edit follows.

It used footage you did not want. Switch that clip off in the Auto panel's footage list, or press Choose parts to pick only the good stretches.

"The edit could not be applied to this sequence." A locked track, or a clip you placed by hand, is in the way. Unlock the track or move the clip, then make the edit again.

Export

The export is slow. Perfect quality (AI), Smooth motion and Enhance detail add work to every frame. Without them, an export is usually faster than real time on a computer with a graphics card.

The export stopped or failed. Keep the tab open and visible, and the device awake and plugged in: the export happens in the tab. Free some disk space. Try a lower resolution, or turn off Perfect quality to see whether the device runs out of memory.

The DriftEdit mark is on my video. The free plan adds a faint mark. Pro removes it.

Projects and files

My clips show as missing. The browser's data was cleared, or you opened the project on another device. Import the same files again: the clips come back.

My project is locked. On the free plan, a project locks 48 hours after its last edit. It is kept with its media: Pro opens it. Exported videos never expire.

"Not saved" in the top bar, with a red light. The device could not save: its storage is probably full. Remove videos you no longer need from the bin, delete old projects, or free space on the device. The next edit tries saving again.

A project has a copy named "(other device)". It was changed on two devices before they could sync: both versions are kept. Keep the one you want and delete the other.

Signing in and sync

Sign-in does not work. Allow the sign-in window (it may open as a pop-up). With email, check your spam folder for the link, and open it in the same browser.

My edits are not on my other device. Check that both devices are signed in to the same account, and that in Profile and settings, under Your edits on every device, the switch is on for both. Press Sync now. Remember that media is never synced: import the files on the other device.

Still stuck?

Write to info@driftedit.app with what you did, what you expected and what happened, your browser and your device. A screenshot helps. If the browser's console (F12) shows a red message, include it.
