Straight to the point and very helpful! Much thanks!

Is there any settings within youtube to sync visual and audio? When using Bluetooth with devices and they don't match?

[almike]

Thanks for help however It did not solve my problem. I'm recording video from iPhone and once I'm trying to sync it with audio recorded from different source It is out of sync. For example I can sync them in first second (using your method) but after 10-20 minutes audio is completely out of sync. Could you help me with that ?

So I would be recording audio from USB mic in a closet to reduce all background noises and then plan to shoot video with a phone. I'm not clear how syncing would work? I would definitely need a detailed script and while shooting video, do a lip sync while reading it out and listening to the pre recorded audio in my headset. Will this small plan work?

Thanks very much. This was very helpful 👍🏼👍🏼

I use a dog training clicker for this because I find the small tight peaks it generates more precise (and easier on the hands 😀). I record my video via camcorder and my audio via Camtasia along with the screen, so I need to export the audio out of my screen recordings to properly EQ it in external software; when I bring it back I line things back up to the peaks so what I'm doing corresponds with what's happening on screen. :)

It would be great if you guys could implement audio synchronization. I use audio synchronization in software like MOVAVI and it's easy as 1, 2, 3.

Super helpful for new youtubers such as myself. Thank you!

Thank you Andy. Hugely useful in a very simple way.

Andy, thanks for the video...my issue is when I edit, all the video and audio are in sync, but when I export to an mp4 format they are out of sync. Any suggestions to avoid this? Should I try doing an upload to my YouTube channel instead of saving local?

[DavidJackson]

I'm having an issue where (and I've gone to view and turned off all snapping). I recorded the audio and video at the same time, I did the clap, but while I can get close, I get more of an Elvis 1950's slap back (maybe not that bad) but I've been able to drag and drop before. Where is the setting to let me go 100% freestyle?

[hopelessbrandi]

i love you thank you so much! this was helpful. it really isnt as stressful as i thought

[KingsBishopChess]

I recorded the Audio and the video on separate devices, and when I put the two files into my editing software, the video portion goes several minutes longer than the Audio, so even though I can sync the beginning, it is not long before they do not match up... any ideas as to why this happened?

[allaweya]

Sometimes when I wish to edit screencast recording created by Camtasia, I find the need to replace ONE SEGMENT of whole Audio by another by using Voice Narration, but the problem is how to get a smooth transmit between old audio and new audio created by Voice Narration option, so I ask if there is an ability in either Camtasia or may be another software like Audacity to accomplish this function so that I can export all segments from Camtasia to Audacity for instance

Recording my tablet screen with camtasia and using a bluetooth mic so I can move around the room, if necessary, while lecturing. Over the course of the 50 min class, the audio and video become unsynced for some reason. The video begins to noticeably lag the audio. Trying to determine the best way to resync. Is there an easy way to record audio and video on the same track?

[MatthiasHeil]

Wouldn't it be great to just let Camtasia do the sync automatically as an option?

[cpan]

Hi there! I made a video with my Logitech C922 Pro. The video play great in.my average laptops, but when I upload it to YouTube, it the video is lagging behind the audio. I'm stuck. Need that video.What to do?

[jetich]

Our wedding was filmed on magnetic tape and the audio was recorded at the sound board of the church. All I have is VLC and Audacity - is it possible to do the sync with free/open-source software or must I purchase something? I'm attempting to rip the DVD and audio disks today (our 15th anniversary was 2 days ago). Thanks for any help!

I record gameplay without a camera using shadowplay. The .mp4 it makes is synced but when I try to edit using Davinci Resolve the microphone and system sounds (two tracks) are both out of sync. I have to manually sync them up but I have a hard time figuring out if I need to move the audio ahead or back. For example I know the audio is playing ahead of the video and you would think that if I move the audio back it would then be closer but then it is even more out of sync. I really just have to spend maybe a half an hour per clip just moving the tracks back and forth, ahead and behind the video in an attempt to eventually get them synced. So my question is; Is there a trick that people can use to remember which direction to move the tracks to get them synced?

Yeah just recorded drums for a TikTok and used a video recorder and a separate audio interface. When a fellow drummer checked it out, at first he commented sounds good. Then he said in a separate post "NM I just saw the end- which was out of sync. I think he believed it wasn't me at all at that point. Frustrating, but I will see if I can see the audio track from the camcorder next time and try to line them up. Chopping the sections somewhat worked but when I rendered it to FB it fell out of sync again. Different resolutions etc.
