![]() But I cannot ask everybody to follow this. In that case the 1-1.1 sec delay would not help in the whole video just a part of that, however in my case 1-1.1 delay on audio solved the issue during my test. I read somewhere the VBR could cause this issues. If I change it with constant 1 sec (or maybe 1.1) then there is no slip in the audio. Then I took the VLC player and tried to change the "audio track syncronization" paramter. There the video is behind the audio about 1-1.1 sec.įirst I thought I cannot check the exact delay as if I take the same rendered video (with audio slip) and try to play within DRS there is no such issue, everything is as per my plan. I even attempted to render with "bypass re-encode when possible" option cleared (so I expected to re-encode everything).Ĭhecked on the same linux and uploaded to youtube and watch on both linux and mobile phone. Rendering output QuickTime with MPEG codec, MPEG4 Video type, however I tried several such as DNxHD codec, without success as I have delay everywhere and only DRS is able to play the rendered file correctly. I have several videos together with a music from a different source. ![]() This audio/video sync problem looks like a DRS bug and not a video source file issue. Sources from mobile phone, music from a wav file. Convert to CFR.ġ7,4,3 Build 10, DaVinciResolve Studio (DRS), Linux. Avidemux does not support encoding with your graphics card due to license issues.Uli Plank wrote:It's all about your sources, not the Deliver settings. These are the only positions within the video, that allow Avidemux to export the video without reencoding. unless you only perform cuts on keyframes (I-frames). choose aac (lav) for Youtube projects or flac for the best quality (gets reencoded on most platforms). ![]() for video part choose copy - which does NOT reencode the video.import the audio track into the exported video by using Avidemux:.perform the same edits on the audio that was done on the video itself (therefore you want the Shotcut audio for comparison).export the audio from that video exported video (for example with Avidemux).In case this doesn't work there is another solution which is uncomfortable: Syncing audio and getting everything in shape was a bit of PITA and I'd prefer to finish everything in shotcut now.īit of a hail mary here, but maybe someone looks at the first few seconds and is like "ha, easy fix, you just do X!" (In audacity it it needs be.) ĭeadline is tuesday and already changed from Davinci Resolve to shotcut due to the ressource hunger of resolve. Maybe you could take a look and let me know what else I can try? I uploaded the clip to YT and the issue persists. Unfortunately the audio keeps stuttering/chopping as if it is clipping but the meters are all fine. I tried staying with the original bitrate and settings the audiofiles from the mic come with, variable bitrate, normalizing (2 pass), compressor, limiter etc. It sounds fine inside shotcut, but regardless of what settings I am using, the audio is stuttering/choppy in the end product (mp4 file basically encoded with the preset for YT). I edited everything together, removed the original camera audio, synched the mic audio and exported with numerous different settings, trying to figure out a solution by trial and error. We were filming a little movie for our uni and recorded the sound externally with a clip-on mic (the sound person did not know better, so it is in mono 22050 kHz, but it is clean, no chop).
