Audio out of sync AFTER importing

try the workaround given in this video

Its fairly simple.

How to Fix Out of Sync Imports in Adobe Premiere Pro (Mp4 video problems) - YouTube

I had the same problem as others with the audio out of sync.

I have now read 20 such posts, what worked for me was combining some information found in a couple of answer posts.

1. Download the freeware HandBrake

2. Enter the file name as the Source File (it also allows batch processing of multiple files)

3. In the Video tab, change the setting from "Variable" to "Constant". According to one post I read somewhere today, this is the chief cause of the out of sync in Premiere.

4. I left the RF setting at 20 (Nope, I have no clue what it means, but it was on another post) Also, one post said to update QF setting, but I couldn't find it.

5. Set the Container to "MP4" and then Type in your Destination file and hit - Run

6. Import into Premier and I think I told it to "Keep Existing Settings" when I imported it. The other way dropped out some audio at the end.

I hope it works for you. I would rather Adobe buy HandBrake and make it a part of their program, but for my problem importing webcam *.wmv this works.

I take no credit for the solution, I wish I had saved all the links from my searching, but alas I didn't ...Good luck.

My problem is a bit different, though just as irritating.  I can't believe Adobe hasn't fixed this given how long since the original post has been up here.  I capture satellite programming from a professional c-band satellite every week.  I use good old fashion Quicktime to capture 30 minute programs for later broadcast.  Our job is to capture the video from the satellite, clip the commercials at the beginning and end of the program and then export a clean version as an MPEG2 file.  Quicktime provides two capture settings: high (which provides a very large ProRes file in 16bit stereo) or medium (which provides a manageable H264 file in AAC stereo).  Both are Quicktime files. 

While I don't have sync issues with the ProRes file, the file that is captured using H264 and the AAC stereo gets pushed out of sync by just enough frames to make it necessary to fix. This is adding about 2 to 3 hours of studio time each week to our production given we have to process about a dozen of these files. Viewing the original quicklime files using the newest version of quicklime or the old Quicktime program and most other video players yields a perfectly in-sync experience; it's just when it's imported into Premier Pro CC 2014 that the sync. problem appears.  One solution that has worked is taking the master file and exporting it again as a .dv file, but this actually takes longer than fixing the sync issue within Premiere. My guess is it may be the AAC audio process that may be the problem.

We only started using Premiere a few months ago and are already re-evaluating whether we should return to FCP.  We were really like most of the Adobe apps within Creative Cloud, but we use Premiere to much to put up with such a major flaw. I do wish Adobe would monitor some of these forums; they have no idea how customer service plays a key role for future software purchases.

Okay Tricaster users.  After YEARS of trying to find a solution that works, we've finally found one!

Instead of taking your long captured files from the Tricaster (mpeg2) after a recording, go into SpeedEdit on the Tricaster and render the file. Grab that rendered file instead.  For some reason Premiere will use the Tricaster M2p file without throwing the audio out of sync as it does with the Tricaster Mpeg2 files.

So glad we figured this out. Hope it works for all of you as well!

Cheers!

+1 for Handbreak! Very fast transcoder!

-100 for Adobe that they're not able to handle a file correctly where a simple windows media player is able to handle it correctly. This is not acceptable for such an expensive software.

It's 2014 and the problem still persists with Adobe Premiere 2014 - audio / video sync on videos over 5 minutes. Here's what I understand after spending too much time with Adobe and Apple tech support. I shoot video using the Ipad Air and MoviePro or FILMiC PRO. Bottom line is that the IPAd, Iphone and many cameras shoot in variable framerate. Premiere needs constant framerate. I have 2 choices. Use another video editor that accepts variable - SonyVegas or a free download like Lightworks. Or convert from variable to constant using Handbrake (or similar product). Handbrake allows you to convert one format to the other. Tons of video's on YouTube, I'll probably spring for SonyVegas because I have too many videos that need to be converted and once I convert with HandBrake I still have to import to Premiere to edit. Conversion takes as long as rendering so it doubles the time to edit and render videos. This is a well known issue with Premiere but Adobe likes to play dumb. They blame it on lack of processor speed, problems with the Ipad not being a professional video camera - but at the end of the day the only issue is variable versus constant framrate. Come on Adobe get your act together and accept variable frame rates.

This was exactly what I needed to straighten out footage taken on my iPad gen 2. Handbrake is awesome. thanks!

The issue is clearly PP not handling variable frame rate video. I also do webcam video and even bought QT Pro for the "reference movie" but that failed (as did the strange suggestion of changing the file extension.

My workaround: Install Handbrake, transcode to a lossless video as constant bitrate and then import that.

This is not so much a fix as a workaround but it is simple. Open file in Quicktime, Save file as and select Save as ref movie. All fixed

Adding my two cents for those that might still be seeking an answer. I eventually gave up and opened the movie file in Windows Movie Maker, edited it, then saved it. Lo and behold, turns out it loses the sync issues once opened in Premiere.

So, if you're having issues with sync issues from a device, open it in WMM or iMovie, save it as a new file, then open it in Premiere.

Sorted.
