![]() ![]() So use -0.15 to compensate for that!įor NicoNico Douga, there’s no delay at all if you use the output from HandBrake. It finally comes a time for me to produce a Twitter video, and it seems to delay an audio by 0.15 seconds. The audio is a little bit faster than what I viewed on PC. Note that a video from Android (which has .mp4 extension) is fine with Facebook. It seems to be 0.145 seconds if the video came straight from Premiere Pro with H264 encoding. From trial-and-error, I discovered that 0.18 seconds is a good value. So to counter that, you need to delay the audio on your video file. You can compare how this might matters in your video below.īefore compensation fix : (That is, in your computer it sounds correct but became wrong after uploading)Īfter the fix : (Now the clip in your computer have audio that is way too fast, but will be corrected in YouTube)Īlso, H.264 to Facebook seems to severely put the audio faster than expected. If yours match mine, probably the audio will be delayed by about 0.1 seconds in YouTube. Here is the metadata of that video, by the way. YouTube will delay back 0.1 seconds, resulting in the correct audio position like what you hear on your computer on your original file. This operation completes as soon after you press enter, because it does not re-render anything. You can use ffmpeg to fix it by make the audio come faster than the correct position with this command : ffmpeg -i input.mp4 -itsoffset -0.1 -i input.mp4 -map 0:v -map 1:a -vcodec copy -acodec copy delayed.mp4īasically this makes 2 streams, #0 is the original one and #1 is the modified one. Before uploading, I have really made sure that it is dead exact. For most video the 0.1 seconds delay is not that noticeable, but in these kind of clips, it became really apparent that the audio is off sync. I occasionally uploads YouTube videos of music games gameplay as a tribute to songs I like. Possible Reasons that Cause Handbrake Output Video/Audio out of Sync Did you happen to find the Handbrake audio sync problem after you convert DVD or convert video to MKV/MP4 In fact, it's not Handbrake but the following cases that makes output audio not match up with the video: 1. ![]() (Exported from Premiere Pro with H.264 preset, then run through Handbrake) ![]() Many DVDs rip fine, but certain ones are off no matter how many times I attempt it.It probably will depends on codecs and other video’s structures, but from my trial-and-error experiment the delay is +0.1 seconds (you hear audio way after the picture) for H.264 .mp4 file. It happens to the same specific DVDs and it's very consistent over and over on numerous attempts. I've tried many different features buttons and other options to try to solve this to no avail.Īny idea how/if I can adjust the speed of the video recording for the rip? It doesn't happen randomly. The video just seems to be in a sped up mode. During the playback for the last several mins the last frame of the movie will freeze until the audio ends. The video seems to be much faster than the sound, often ending 10 to 15 mins before the sound. With a number of DVDs of all ages, I'm running into an issue on some of them where after I check the rip to make sure it came out okay, I see that the sound is drastically off from the video. I've been ripping several DVDs to my hard drive to watch during traveling. I apologize if this is a repeat topic, but couldn't find anything in a forum search. ![]()
