Or, if your video records at 24 fps but the Camtasia project is set to 30 fps, then the video will play faster and end before the audio. As a result, your video plays slightly slower than when you recorded it and is 2 seconds longer than your audio. After ten seconds, you have not reached the end of your video because it has only shown 250 of the 300 recorded images - so there are still 50 images left over, which is another 2 seconds. What happens? For every second, your video now only plays 25 frames. But you still have those 300 single images!
You transfer your video to your computer and start editing it in your software - in this case Camtasia, but the Camtasia project is not set to 30 fps, but, maybe 25 fps or something else. You have recorded your audio at the same time, also 10 seconds long. These images are shown one after each other and make up the video. So, if you record 10 seconds, you will have 300 single images, also called frames. This means that for every second, your video records 30 images. Let's say you have recorded your original video with 30 frames per second (30 fps). The problem you are describing is exactly what happens when a video gets recorded with one framerate, but edited with a different framerate. I don't have Camtasia Studio, so I don't know if it can be done.Ĭan I just reiterate what hughconway was saying: Your original issue is most likely the videos framerate. This can be done in Audacity, for example, but if you can edit the audio track seperately in Camtasia Studio, then that's the best thing to do. How much does your audio track deviate from the video? One possibility would be to edit the audio track afterwards, by adding very short silences or removing a part, where the tracks start to deviate from another, considerably. That's the way I do it, and I've never had out-of-sync problems. In many video editors, you can unlink the audio and video, zoom in, then drag the audio track to match up with the video. Except I record directly to WAV on my piano, then sync the WAV file to the video, recorded seperately.įirst I used FFMPEG for the syncing, then I got Cyberlink PowerDirector. The piano videos I've posted on my YouTube channel (see below) have been made in a similar way, as you do. This is indeed strange, but I've read about problems like these before.
What might be the reason? This should not happen as this video was shooted simultaneously while recording the MIDI(for AUDIO) Please tell me how to fix it. I have also tried to adjust the clip speed but it didn't help.
In other words, if the audio and video is same, both start at the same time,then they should end at the same time too. When I sync the starting of the song, then the ending gets messed up. I've tried so much and there is no error done by me in the syncing process. However, it does not get synced properly. Then I take the audio file and try to sync it with the video file with the help of CAMTASIA STUDIO 8. After exporting the MIDI, I import the midi, use PIANO ONE VST and then export it as mp3 and wav in REAPER I then export the midi the midi from cubase.
Then, for recording my midi, I use CUBASE 5 while my Android phone's camera records the video simultaneously. It has a USB-MIDI port through which I connect the piano to computer. I have a Casio Privia px-760 digital piano. There is a BIG PROBLEM which face while recording a piano video.
