- Voxalike WebM to MP4: Video exports are prepared in your browser and saved as WebM, so MP4 needs one conversion step
- Export first: Finish the dub, keep the tab open during browser-side preparation, then download the file
- Best free tools: FFmpeg, HandBrake, and VLC all convert WebM to MP4 fully offline
- Quality rule: Re-encode with H.264 video and AAC audio at CRF 18 or lower for near-original results
- Recovery window: Recent Dubs data is temporary, so save every multiplayer result before it expires
Why Voxalike Saves Dubs as WebM
Voxalike is a free HTML5 browser dubbing game, so the entire export pipeline runs on your side of the screen. When you complete a session, the game prepares the finished dub in the browser and delivers the video as a WebM file. Converting your Voxalike WebM to MP4 is simply the final compatibility step before editing or posting the performance.
Browsers default to WebM for a reason: it is the native output of modern browser media engines, it keeps file sizes reasonable, and it requires no server-side processing. The trade-off is compatibility. Some mobile editors, older devices, and upload flows still expect MP4, which is why a quick conversion belongs in every player's routine.
| Export Option | Shape | Delivered As | Best For |
|---|---|---|---|
| Landscape video | 16:9 widescreen | WebM video | YouTube uploads, desktop editing |
| Vertical video | 9:16 portrait | WebM video | TikTok, YouTube Shorts, Reels |
| Audio only | No video | Audio file | Re-editing, podcast clips |
A note on screen recording: capturing the result screen with OBS or a phone camera looks like a shortcut, but it re-records audio through your speakers, loses the clean mix, and locks you to real-time capture. The export pipeline hands you the finished file directly, so export first and convert second.
MP4 containing H.264 video and AAC audio remains the most widely accepted combination across video editors and social platforms. WebM support varies by app and device, which is why the MP4 copy is the one you share.
Export Your Dub the Right Way First
A clean source file makes conversion painless. Before opening any converter, walk through the in-game export flow and make sure the WebM you download is complete. The same flow applies to Solo sessions and finished multiplayer rooms.
Complete the Dub
Finish every assigned character line and reach the completed result screen. Export options only become relevant once the session's required dialogue has been recorded.
Let the Browser Prepare the Video
Voxalike renders the finished dub on your side. Keep the tab in the foreground and stop your device from sleeping until preparation finishes.
Pick Landscape, Vertical, or Audio
Choose 16:9 for standard uploads, 9:16 for short-form platforms, or audio-only when you only need the dubbed track.
Download and Back Up the WebM
Save the file immediately and copy it to a permanent folder. Browser storage is not a long-term archive for finished dubs.
Retry Instead of Rerecording
If preparation or export is interrupted, use the built-in retry flow. The game keeps the current result available so you can try again without redoing your takes.
Since v1.4.0, supported multiplayer sessions can reopen recently completed results through Recent Dubs, but the recovery data is temporary. Reopen and export any result you want to keep before that browser-side data is removed. Details are in the official recovery guide at voxalike.com/guide/recover-recent-dubs.
Voxalike WebM to MP4 Conversion Methods
Every method below produces a valid MP4; they differ in speed, control, and convenience. Pick based on how many dubs you convert and how much tuning you want.
FFmpeg
- Full codec control from the command line
- Batch scripts convert dozens of dubs unattended
- Free and open source on Windows, macOS, and Linux
HandBrake
- Preset-driven desktop application
- Queue support for multiple files
- Free download from handbrake.fr
VLC
- Converts inside the player you may already have
- No extra install if VLC is on your device
- Best for quick one-off conversions
Online Converters
- Zero installation in any browser
- Fine for short clips and small files
- Watch file-size caps and privacy before uploading
| Method | Offline | Batch Support | Quality Control | Learning Curve | Best For |
|---|---|---|---|---|---|
| FFmpeg | Yes | Excellent | Full manual control | Steep | Large libraries, scripted workflows |
| HandBrake | Yes | Queue | Presets plus tuning | Moderate | Desktop users who want presets |
| VLC | Yes | Limited | Basic profile only | Easy | Quick single-file converts |
| Online tools | No | Limited | Often locked | Easiest | Small clips where installs are not allowed |
Install Your Tool
Get FFmpeg from ffmpeg.org, HandBrake from handbrake.fr, or VLC from videolan.org. All three are official, free sources.
Load the WebM Export
Open your saved Voxalike WebM in the application, or point a terminal command at the file path.
Target H.264 Video and AAC Audio
This pairing plays back reliably in phone editors and every major social uploader, which is exactly what you want from the MP4 copy.
Convert and Verify Playback
Check the start, middle, and end of the MP4 for audio sync before you delete the WebM original.
Run ffmpeg -i dub.webm -c:v libx264 -crf 18 -preset slow -c:a aac dub.mp4 for a near-original copy. Per the official FFmpeg documentation at ffmpeg.org (accessed August 2026), CRF 18 is visually close to lossless for most source material.
Platform-Ready Settings for TikTok, Shorts, and Reels
Short-form platforms re-encode everything you upload, so hand them a clean, high-quality MP4 to start from. Voxalike's vertical export already matches the 9:16 target shape, which means a straight conversion with no cropping is all you need.
| Platform | Container | Video Codec | Aspect | Safe Resolution | Audio |
|---|---|---|---|---|---|
| TikTok | MP4 | H.264 | 9:16 | 1080x1920 | AAC |
| YouTube Shorts | MP4 | H.264 | 9:16 | 1080x1920 | AAC |
| Instagram Reels | MP4 | H.264 | 9:16 | 1080x1920 | AAC |
| YouTube standard | MP4 | H.264 | 16:9 | 1920x1080 | AAC |
- Export vertical directly from Voxalike instead of cropping a landscape file later; cropping can cut captions baked into the frame.
- Keep the original resolution — upscaling a smaller WebM to 1080p adds no detail.
- Prefer quality-based encoding (CRF modes) over fixed bitrates when your converter offers both; for 1080x1920 output, a video bitrate in the 8-12 Mbps range keeps fast dialogue cuts clean.
Because the vertical export is already portrait, your converted MP4 drops straight into TikTok, Shorts, or Reels with no letterboxing, rotating, or reframing required.
Pre-Share Checklist and Common Fixes
Run through this list once and most export problems disappear before they reach your followers.
Before You Post:
- WebM original downloaded and backed up outside the browser
- MP4 copy encoded with H.264 video and AAC audio
- Audio sync checked at the start, middle, and end
- Vertical file confirmed at 9:16 with no cropped captions
- Recent Dubs reopened and saved before recovery data expires
| Problem | Likely Cause | Fix |
|---|---|---|
| Preparation stalls | Tab backgrounded or device slept | Keep the tab foreground, then retry the export |
| MP4 has no sound | Audio codec dropped in conversion | Re-convert with AAC explicitly enabled |
| Audio drifts out of sync | Variable frame rate source | Re-encode at a constant frame rate |
| WebM will not open | Missing codecs on the device | Open in VLC or update the browser |
| Recent dub disappeared | Recovery window expired | Reopen Recent Dubs sooner in the next session |
Avoid closing the Voxalike tab while the browser is still preparing a video. Background throttling can interrupt the render, forcing you into the retry flow instead of a finished file.
Frequently Asked Questions
The questions below cover the export and conversion issues Voxalike players search for most often.
Q: Does Voxalike export MP4 directly?
No. Video exports are prepared in the browser and delivered as WebM files. Download the WebM first, then use any free converter such as FFmpeg, HandBrake, or VLC to produce the MP4 copy.
Q: Will converting WebM to MP4 lower my quality?
Re-encoding rewrites the video data, but at CRF 18 or an equivalent high-quality preset the difference is practically invisible. Avoid low-bitrate defaults and online converters that compress aggressively.
Q: Which method handles many dubs at once?
FFmpeg scripts and HandBrake's queue convert entire folders unattended. Online converters usually cap file count and size, which makes them a poor fit for batch sessions.
Q: Can I recover a dub I forgot to export?
In supported multiplayer sessions, Recent Dubs added in v1.4.0 lets you reopen recently completed results for another export attempt. The recovery data is temporary, so reopen and save the file as soon as possible.
