![]() ![]() ![]() The Old version of iMovie worked fine for both video and audio. I am stuck and stumped as to why this is happening and what I can do to fix it, which appears to be nothing. I have turned on and turned off Variable Bit rate encoding thinking that would make a different and fix the problem. I have tried changing the format to a more iMovie compatible one, mp3, mp4 audio, AAC (both low profile and main profile) and m4a, and upping the bitrate to 256 rather than 192. However, when I try to import it into iMovie, delete the old audio *that came with the original video, and then try to add the audio I have ripped and save, it sounds robotic and horrible, and nothing like what I ripped at all. I ripped the audio from another movie (nothing copyrighted) and it plays just fine in VLC and iTunes. However, I have real problems importing audio into iMovie itself, and then into the timeline. Of course that's your call and largely depends on the use you intend to make of your final product.ĭistorted audio when importing I have upgraded to the latest version of iMovie (as of today, 10.1.11). I doubt that anyone's eye could detect a quality difference unless one zoomed in and examined the pixels. Pro res really isn't necessary unless you are doing some intricate professional editing. Also, you could try reimporting your present final product back into a new iMovie project, detach and split the audio as necessary, and correct the sync there.įinally, you might consider exporting with the Better Quality setting rather than the Best Quality (pro res) setting. ![]() You can do that by putting the audio clip into a new iMovie project and exporting it with the audio only setting in the iMovie export box, that will give you a drop down menu with codecs to choose from.īefore doing any of the above you might simply try running your present final product through Handbrake and see if that straightens everything out. See if that cures the sync issues.Īlso, you can try converting you. Then save and import the converted clip into iMovie and export again. Wait a couple of minutes for the conversion to complete. Navigate to your video and choose it as the source from the resulting screen. Re-rendering often cures issues.Ī simple way to do it is to open Handbrake and do a File/Open Source. Convert the clips even if the codec already is indicated to be Mp4/AAC. You may want to consider converting all of your original clips (or duplicates of them if you want to preserve your original formats) to Mp4/AAC with the free download Handbrake, to impart some uniformity to the various formats. It is best to have as much uniformity as possible with codecs, formats, and frame rates. In addition, your iMovie export with best quality (pro res) settings is exporting your original. The different codecs and formats may render slightly differently when exported. Maybe some have different frame rates as well. mov clips can contain different codecs from each other as well. MOV file.Ĭan I ask how should I go about resolving this?Ĭombining media from different cameras, and audio with different sample rates, plus different video formats, can cause sync issues. The audio has been trimmed here and there in iMovie to cut out small parts, but always lined up manually as close as possible to the video, and as I mentioned there is no noticeable lag anywhere in the iMovie preview, but it only becomes apparent in the exported. MP4 clips, and maybe a tiny number of the. I've read elsewhere that the difference between 44.1kHz in the audio and 48kHz from the video could cause this problem, but the strange thing is that I'm only seeing this happen with some clips and not others (mostly with the. MOV file additionally says 'Timecode' within the Codecs section, and has an additional section saying 'Colour profile: HD (1-1-1)' On the 'Get Info' for each type of file, both the. mov, under better quality compression, 720p (as this gives 26GB file), I noticed some of the shots are slightly out of sync with the audio, and only in the exported file. I've been lining up the audio to the video manually between edited shots, and it looks like everything is in sync within the iMovie preview playback.
