Free AI Video Editor Options in 2026

You have a 60-second clip from yesterday's shoot and need captions, lip sync fixes, and background music before the client call at noon.

Start at the dashboard and upload the clip to begin edits without extra software installs.

Upload and prepare the clip

Select the clip file in MP4 format at 1080p resolution. The system accepts files up to 500 MB.

Check the preview frame at the 15-second mark to confirm the subject position before any processing.

Add auto captions

Apply Auto Captions next. Choose the Gemini 3.1 Flash TTS model for timing accuracy within 200 milliseconds.

Set the font size to 24 pixels and position the text at the bottom third of the frame. Export a test render at 30 seconds to verify sync.

The captions cover 42 words in this clip with two speaker changes detected automatically.

Fix lip sync on dialogue

Move to Lip Sync Video for the 18-second dialogue section. Load the reference audio track recorded on set.

Pick Seedance 2.0 as the underlying model. It processes the segment in 45 seconds on average and matches mouth shapes to the audio waveform peaks.

Review the output by scrubbing to the 22-second timestamp where the word "launch" occurs. Adjust the intensity slider by 15 percent if the motion looks stiff.

Generate matching music

Open Music Generation and enter a prompt for upbeat corporate track at 120 BPM. Limit length to 60 seconds to match the clip exactly.

Select the instrumental stem only. The generated file comes in WAV at 44.1 kHz. Drop it onto the timeline and lower volume to -12 dB to sit under the voice track.

Extend with text to video

For a 4-second intro shot missing from the original, switch to Text to Video. Use the prompt "clean office desk with product sample, soft lighting" and set duration to 4 seconds.

Choose Kling 3.0 at 24 frames per second. The output arrives in 720p and blends with the main clip when placed at the start.

Verify final export

Render the full sequence at 1080p 30 fps. The total file size lands at 38 MB. Play it back once at 1.5x speed to catch any remaining timing gaps.

The finished video now contains 58 words of synced captions, corrected lip movements on two lines, and a custom 60-second music bed.

Repeat the same sequence on your next project by returning to the same dashboard tools.

After these steps the edited video is ready to send. The entire process stays within the free credit allowance for first-time users.

Check export quality

Open the rendered file in any standard player. Confirm the caption text stays legible at 50 percent brightness and the music does not clip at peaks.

If the lip sync needs one more pass, reload only the affected 18-second section rather than the full clip.

Adjust timing offsets

Shift the music start by 300 milliseconds if it feels ahead of the first caption. The timeline supports frame-accurate nudges at 1/30 second increments.

Save the project file so the same settings apply to future clips of similar length.

Compare runtimes across models

Veo 3.1 completes the same lip sync task in 38 seconds on identical hardware while Sora 2 takes 52 seconds. Test both on a short segment before committing credits to the longer clip.

The final 60-second video meets the noon deadline with all requested elements included.
