Music Video is Extremely Out of Sync!

Post by The Wise 1 » Thu Dec 28, 2017 5:25 am

I am trying to compress a video down from 3 gb to be able to upload onto youtube. It is a music video for a song I've created, but once it is processed by Handbrake the audio and visuals are off. The audio starts at around 50 seconds from where it is supposed to start, but the visuals start at the correct time. No tinny-ness or loss of audio quality can be heard, just the audio-visuals being clearly out of sync.

I made the video with ZGameEditor Visualizer in Fl Studio 12, and rendered it into a 60 fps 1920 x 1080 mp4. I run it through handbrake on the "normal" preset and I get a video with the above-mentioned error.


Handbrake Version 1.0.7


I am using Windows 7.

When is the audio suppose to start? The first audio timestamp (which we can see in the log) says the audio starts about 52 seconds after the start of video.

That's exactly the problem. The audio is supposed to start at 0 seconds, yet it is starting at ~52 seconds

So, the source is an "MP4", eh? Look again...

We're proceeding on the basis that this Vista-era Media Foundation source is actually synced in the first place, yes?

There's a whole bunch of reasons why this might not be working, from absolutely using the wrong HB preset, to not using the HB Nightly, to using an inappropriate or incompatible export format from ZGameEditor.

I have my own suspicions, so please do the following:

1. Download FFMPEG from https://ffmpeg.zeranoe.com/builds/

2. Copy what's in the BIN\ directory to somewhere in your path (or into the dir with the source video)

3. Open a Command Line in the same directory as the source file

4. Enter: ffmpeg -i "Don't You Want Chinese Food.wmv" -c:a aac -c:v h264 SyncedOrNot.mp4

5. Tell me if SyncedOrNot.mp4 still lags the audio at the start.

This result will narrow all the possibilities down by at least half.
