So after a lot of online searching, I did find an answer to fix this problem, but not in Blender. I also found ShotCut to be less stable than Blender. I also experienced similar out-of-sync issues in ShotCut a year ago while working with cheap action cam H.265 files. I believe the issue continues to be with the way H.264 rendering in Blender is implemented. The time required to get to final file more than triples though.

This workaround is relatively painless and produces good-quality results because there's only a single lossy compression step. End result produces a smallish-size file with A/V that is in sync. Use HandBrake open source video transcoder to convert FFmpeg file into H.264 (or H.265).However, the audio remains in sync all the way through. This produces a lossless file that is about 27 times bigger (13.8GB for 10mins) than H.264 codec file (0.5GB). Change Video Codec to "FFmpeg video codec #1".What worked better for me is the following: Very frustrating, and a lot of wasted time. Rendered result still didn't match what GUI showed. I tried running rendering after a clean boot, gave Blender highest resource priority in Win10, allocated more memory to caching, etc. I didn't even cut or merged any segments of the source video. Audio and Video tracks are of the same length. In Blender's preview mode everything looks in-sync.

Source was as-is (3.6GB, 10mins) file from Canon EOS 5DMKII, which is an old camera, so pretty much any software can handle the encoding. Blender v2.92.0 - I experienced the same as described out-of-sync problem with rendered videos that were over five minutes long. I am a noob in video/audio codecs so please forgive me if I used some incorrect nomenclature above. So if anyone figured this out please let me know. This lag (audio is a few frames ahead of the video) is noticeable only in longer videos (>12 mins, my video is 1 hr long) suggesting a very small rendered rate difference between the video and the audio.Īlso, note that the animation plays absolutely fine in Blender, so all I could figure out was that this was a rendering issue.

Someone online suggested exporting the video and audio separately and then combining them using a command-line tool like FFMPEG, this also failed.

Initially, I was combining videos with different frame rates and thought that might have been an issue (although animation played as expected in Blender), so I recreated the source videos to ensure all videos I was using in my project had the same frame rate, but this also did not work. Then I thought that my scene audio frequency might have been an issue since it was initially 48kHz and my videos were at 24kHz, so I changed the scene audio frequency to 24kHz, this still failed to solve the issue.

I used the 'Audio-Sync' option in the sequencer but that made no difference.

Until, I created this awesome project composition and when I exported the animation as a video file, the audio was out of sync :(.Īudio is in-sync with video when the animation is played in Blender but is out-of-sync in the rendered video.

Ok, so I found out that Blender has this really cool video-editing interface and I was beginning to love it.
