Or, Womble and VideoRe-Do have tools to fix “time code errors” and sometimes that will fix sync problems. (If you want to keep the same audio/video format you can just use a slightly-lower or slightly-higher bitrate.) …And sometimes editing or re-encoding the file will cause it to go out-of-sync. Sometimes, simply re-encoding with your video editor or with a free tool like XMedia Recode will fix sync problems, but re-compressing may reduce the audio/video quality. Then you can calculate the necessary speed change (which you’ll probably have to do with Audacity).
Besides converting, XMedia Recode also has basic editing abilities Output to 'Video and Audio', 'Video only' or 'Audio only' Copy video and/or audio tracks from input file (to avoid conversion) Presets (called Profiles) for various media devices (e.g. You can also convert format in Avidemux, though XMediarecode 's presets make it convenient. XMedia Recode can only convert unprotected DVDs. Combine first using Avidemux save to a new AVI using 'copy' for video and audio. You should be able to do that with just your video editor. Is there a way to combine multiple videos (Part01.avi, Part02.avi, etc) into a single video H.264/m4v. If the drift is constant you can trim a some time off the beginning (or add silence to the beginning) until it’s in sync at the end.
The tricky part is figuring-out how far off it is. So, it may take several tries to get it fixed.ĭo you think the drift is constant? That is, do you think it gets worse over time so you start to notice it half way through, then it gets worse by the end? XMedia Recode covers all major file formats, and FFmpeg and profiles have been updated with version upgrades, so it is recommended to use the latest version. I don’t know exactly what causes that, but it tends to be more of a problem with the more-compressed video formats (MPEG4, etc.). 108 subscribers Subscribe Like 7.1K views 5 years ago There are times when a video geek needs to merge a silent video with its proper audio track.

Audacity is an audio editor and it can take the audio out of the video (you’ll probably need to install FFmpeg) but it can’t put it back.Īnd sometimes, just extracting and re-multiplexing (re-combining) the audio can cause it to go out-of-sync. at to another, compressing the files in the. You’ll need a video editor (or other tool) to re-combine the audio & video. HandBrake HandBrake is an open-source, multithreaded video transcoder- it converts digital media from one form.
