Premiere pro sync audio and video8/11/2023 ![]() ![]() In the sequence copy, trim your two audio tracks back to a very short span where each picked up the same audio clearly (maybe just the clap in the beginning, or a section where a few loud bursts happen). Make a copy of the sequence (just in case)Ģ. If the two audio tracks are "different" enough for PP to not match them. ![]() maybe one mic was very close to a voice and picked it up clearly but the other mic was far enough away that it just didn't pick up. Like audio drift? (One device gradually slows down the audio, barely perceptible unless the file is really long.) Or. it could be that there actually is a slight discrepancy that is enough to throw the algorithm off. Waiting 15 minutes and no result must be super frustrating. I won't use the audio from the cameras in the final project, they will be used just to get all cameras in sync, so there is no point on moving their audio.So sorry the previous suggestion didn't work for you. I can get the professional audio in pefect sync with one of the cameras but the other two will look slightly off. And the camera 3 may be a little "late" from camera 2. The problem is: it's impossible to align the click tracks from the three cameras because camera 1 will be less than a frame "earlier" than camera 2 on my timeline. The clips will be synced using the click track that the cameras's mic picked up as a reference, so there shouldn't be an issue getting allin clips sync. Now, since the shooting was made with just one camera, but there are three different guitar takes, it's just like having three cameras, since there are three clips on my timeline. So, this process repeats with the third guitar part. Then I will record a second guitar part and I start shooting again, and like the first guitar part, there are multiple takes until I get the right one. I'm shooting myself while I'm recording guitar on a song, so there are multiple guitar takes until I get it right. Maybe I didn't make myself clear on my issue with the sync between the cameras. as both someone with years in camera work and now video post, and as a life-long musician. I did a video recording, and from that, told people I could prove the organ wasn't keeping up with the bells! Because naturally, with the bells right next to the camera, our sound arrived first most of the time. And got some comments that it was awesome, others that well it was nice but can't the bells keep up with the organ? After that, we never 'stuck the landing' for getting accurately "with" the organ. We hadn't been doing too bad before he added the antiphonal organ. ![]() Of course, we needed to play exactly with those pipes, but before and after, when he was using the main organ, play ahead of him. To the "antiphonal organ" stop of pipes that were also in the balcony with us. Then the organist decided to change "stops", the selection of pipes, for one section. So it took some practice on my part to keep my group directed. Timing when 'we' played against the organ was tricky enough, as if we played what sounded "with" the organ, our sound got to the audience in-between as as notably late. Including directing a hand-bell choir performing in a loft at the back of the sanctury while the organist and the main pipe installation were at the front, 200 feet away. Of course if you are sitting at the west end everything is even furthur out of sync.īesides this video/video-post thing, I'm also a musician and have performed in, directed, and recorded various music things. If using these pipes with the main organ the organist has to play the pipes a beat early so that their sound is in sync with the other stops. In St Paul's cathedral in London there is a rank of trumpet pipes over the west door, a couple of hundred feet from the rest of the organ. When we made the first dvd we tried various sync variations and the only one that looked right was to have the note heard as the key was pressed, this, in real life, never occurs. The recordist I work with mics the organ about 80 feet down the nave so that is 2 frames late. So just listening live at the console the sound is 2 or 3 frames late. The pipes themselves are often tens of feet away and some are closer than others. When the organist presses a key you expect to hear the note but with some stops there is a delay before the pipe speaks so the sound is late. I have made a dozen or so dvds of organ recitals, shot around the organ consoles. Try moving your 'wrong' pictures a frame earlier it might all heal up. ![]() If you have close sync in a video and it still looks 'wrong' there's a good chance the sound is before the pictures, the brain cannot cpoe with this. The human brain expects this and it looks natural. In the natural world sound is allways behind the picture, due to the fact that the speed of light is a lot faster than the speed of sound. ![]()
