MP4 Audio Sync Correction

@studiogo07

Hello, We can correct the consistent lip-sync issue by precisely identifying the affected speaker’s offset and applying the required global audio adjustment across the 10-minute MP4. Our experience in video editing, audio synchronization, Premiere Pro, DaVinci Resolve, and technical media processing is directly relevant. We will preserve the original resolution, frame rate, H.264/AAC quality, and avoid unnecessary re-encoding wherever technically possible. We will deliver the corrected MP4 along with the exact offset applied, ensuring the dialogue remains synchronized throughout the complete recording. Thanks

Hi, I can fix the **audio/video synchronization** in your 10-minute MP4 and apply the global offset needed to keep the affected speaker’s dialogue aligned throughout the video. Since the delay is consistent and the two speakers do not overlap, I can use the unaffected speaker as a reference and determine the precise offset for the affected speaker. I’ll handle: * Frame-accurate lip-sync correction * Precise global audio adjustment rather than scene-by-scene editing * Preservation of the original H.264/AAC quality wherever technically possible * Maintaining the original resolution and frame rate * Quality check across the full 10-minute video * Corrected MP4 ready for standard players * A brief note specifying the exact offset applied **Turnaround:** Same day / within 24 hours Send me the MP4, and I can analyze the timing and apply the correction. Best regards, Nabeel Akhtar

My decade-long experience has honed my attention to detail, framing each element in compositions such that it aligns seamlessly and conveys the intended message. This is especially valuable when it comes to sync correction like this where one second off can mean out-of-sync lip movements. I pride myself on delivering quality work that doesn't compromise or degrade original elements. Preparing visuals and footage for different platforms has taught me to optimize without losing anything essential—perfect for maintaining the existing resolution, frame rate, and overall quality you expect for this project. Moreover, I'm well-versed in explaining the changes I make which will be key to ensure continuity if you need this fix replicated again. For a reliable partner with an eye for precision and impeccable attention to detail who won't rest until both video and audio are running harmoniously throughout, look no further!

A sub-second, consistent lip-sync drift on one speaker only — that’s a clean, precise fix, not a guessing game, and precision is exactly what I bring to this kind of work. I’ll isolate the offset frame-by-frame, apply a global shift on just that speaker’s audio, and export back to H.264/AAC with zero quality loss — same resolution, same frame rate, no re-encoding artifacts. You’ll get the corrected MP4 plus the exact offset noted so it’s reproducible if you ever need it again. Send the file over — this is a fast, clean turnaround.

Send me a 30-second snippet of your MP4 right now in chat—I will fix the lip-sync and send back a free test sample within 15 minutes so you can verify the sync before hiring me. Since only one speaker's audio lags (and there is no overlap), applying a blanket global shift would ruin the second speaker. I will split the audio track at speaker transitions and apply the exact millisecond shift only to the affected speaker. What you will get ($60 USD): Frame-Accurate Lip Sync: Perfectly realigned speech for the full 10-minute video. Zero Quality Loss: Rendered using exact source settings (H.264/AAC) preserving the original resolution and bitrate. Offset Value Report: A brief note detailing the exact frame/millisecond offset applied for your reference. Drop a short clip in chat, and I’ll send the synced sample right back to you! Best, Vahid

One thing worth flagging before I quote: since only one of the two speakers lags and they alternate without overlap, this technically isn't a single global shift across the whole track, that would fix your affected speaker but push the other speaker out of sync in the opposite direction. The real fix is identifying that specific speaker's segments and shifting audio only within those windows, keeping the unaffected speaker's segments untouched. Quick check: does the source have separate audio channels per speaker (e.g., two mic inputs), or is it one combined mono/stereo track? That determines whether I can isolate the fix cleanly by channel or need to do it by timestamped segment matched to lip movement. My approach: identify every segment where the lagging speaker is talking, frame-match audio to lip movement for each one, apply the consistent sub-second offset precisely within those windows, and verify sync by eye across the full 10 minutes before export. I'd handle this without re-encoding the video stream, working with the existing H.264/AAC to preserve original resolution, frame rate, and quality exactly as specified, only touching what needs to move. Deliverable: corrected MP4 plus a short note detailing the exact offset applied and which segments it was applied to, so you can replicate it later if needed. Could you confirm whether the audio is on separate channels per speaker, or one combined track?

Sir, my rate is very cheap, and I can complete this cleanly without unnecessary quality loss.

@SaturnCube

Since only one speaker is out of sync, would you prefer I split the audio track per speaker and shift just the affected parts, or is a single global correction across the whole video acceptable to you? Looking forward to your reply so we can iron out the details and move ahead.

Hi there, Your MP4 has a consistent audio lag, so I can correct it with a clean global shift and keep the lips in sync throughout all 10 minutes. I have strong expertise in Video Production, Audio Engineering, and Video Services, and I’ll preserve the original H.264/AAC quality while matching the timing frame-accurately. I’ll measure the offset, apply the exact audio shift without unnecessary re-encoding, then export a smooth MP4 and include the applied delay so you can replicate it later. Best regards, Marko

@jodydupreez

A single-speaker sync issue that only shows up in alternating segments needs a careful frame-by-frame check even though the fix itself is a simple global shift, since misjudging the offset by even a couple frames is obvious on lip movement. We fix audio sync issues in video, applying precise frame-accurate offsets without touching resolution or quality. Isolating the segments where only one speaker's audio lags, then applying a clean global shift that stays frame-accurate throughout the runtime, is exactly the kind of precise, no-shortcuts sync fix we handle well. We keep the original H.264/AAC quality fully intact with no re-encoding degradation, and we don't just say we're precise, we have 75+ 5-star reviews on similar projects and rank in the top 1% among 75 million users! Ready to take a look at the file and get the offset locked in. Regards, Jody.

@mikaeelg1

I can correct the audio sync issue in your MP4 where the speaker’s lips move slightly ahead of the sound. I have worked on multiple video projects requiring precise audio-video synchronization to ensure perfect alignment. My approach would involve analyzing the audio and video tracks separately, then adjusting the timing to match lip movements without degrading quality. Do you already have the original video and audio files separately, or just the single MP4?
