I have a 20-minute video in Portuguese, fully edited, currently playing as an MP4. The visuals are synchronized, but I need the speech to be in Spanish. I need every spoken word to be perfectly aligned with the mouth movements. Your only task is to lip-sync this across the entire timeline—no additional color corrections, cuts, or audio adjustments are necessary. You will receive: • The rendered MP4 file and the separate Spanish audio track. What I would like to receive: • An MP4 file with the Spanish audio. Acceptance criteria: • Speech and lip movements must be perfectly synchronized from beginning to end in standard players. • No new glitches, problems, or artifacts. • The duration, edits, and overall structure must remain exactly as delivered. Please let me know which software you prefer and an estimated deadline. Once the synchronization is working perfectly, we're done!

Lip-sync dubbing across a full 20-minute timeline is one of the most technically demanding post-production tasks precisely because a single frame of drift compounds across the entire video, and the difference between passable and convincing comes down to how carefully the Spanish audio was paced to match the original mouth movements before the sync work even begins. I will process the MP4 and the separate Spanish audio track using AI-assisted lip-sync tools combined with manual frame-level adjustments where the automated pass needs tightening, which is the only reliable way to handle a full 20-minute piece without drift accumulating mid-video. The output will be a clean MP4 with Spanish audio synchronized to mouth movements from start to finish, matching your original duration, cuts, and structure exactly with no added corrections or artifacts. Before I confirm the timeline, one question: was the Spanish audio recorded with the lip-sync pacing already matched to the original Portuguese delivery, or was it translated and recorded naturally, because that significantly affects how much correction work the synchronization will require?

Please let me know which software you prefer and an estimated deadline. Once the synchronization is working perfectly, we're done! The challenge here isn't syncing a few lines, it's maintaining flawless lip-sync for 20 uninterrupted minutes. Small timing errors accumulate over longer videos, so every section has to be checked to ensure the Spanish dialogue matches the speaker naturally from beginning to end. I'd use an AI-assisted lip-sync workflow together with Adobe Premiere Pro to align the Spanish audio while preserving the original edit, pacing, and video quality. I've handled long-form dialogue synchronization projects before where the priority was frame-accurate lip movement without introducing artifacts or changing the structure of the video. You'll receive an MP4 with the Spanish audio perfectly synchronized, keeping the exact duration, cuts, and overall edit intact. My estimated turnaround is 2–3 days, depending on dialogue density and the number of on-screen speakers. Before I begin, I'll also review the entire timeline to catch any sections where manual adjustments are needed beyond the AI pass, ensuring the final result looks consistent throughout. Does the video feature a single speaker for most of the 20 minutes, or are there multiple speakers with frequent close-up shots??

✅ Ready to jump in and get this done the right way—clean, fast, and reliable. ✅ I understand you need a 10-minute VSL where the lip sync is corrected and the final video looks smooth, natural, and professionally edited. The key here is making sure the voice and mouth movements feel aligned without distracting timing issues, while keeping the overall video flow intact. I’ve worked on video editing projects involving timing corrections, audio-sync alignment, and post-production cleanup where precision and attention to frame-level detail were important. Lip sync fixes require careful frame matching and sometimes subtle adjustments to maintain realism. My approach is to first analyze the existing sync issues, align audio with visual cues frame by frame, and make adjustments without affecting the natural motion or pacing of the video. I ensure the final output is clean, consistent, and ready for publishing. Let’s get your VSL polished and professionally synced.

Perfect lip-sync across a full 20-minute timeline only works when the alignment is handled frame-by-frame against the new Spanish audio, not just replacing the track and hoping timing holds. A workflow in Adobe After Effects or DaVinci Resolve Studio is usually best for this kind of precise mouth-to-speech matching, especially when the original edit already exists and must not be altered in structure or duration. With the MP4 and Spanish audio, I would keep the visuals locked, rebuild the audio sync curve, and adjust phoneme timing so the mouth movement matches naturally from start to finish without introducing jitter or drift. Once I have the files, this typically takes around 1–3 days depending on how tightly the original Portuguese timing was animated. Do you already have any existing face tracking or is this purely a re-sync on a standard video edit? Best regards, Fizza Nadeem K
