But since you say you've been managing so far, I may be wrong about that. I probably would've questioned whether OpenShot is well-suited to your needs, for that reason. I wouldn't have thought that's enough accuracy to do the kind of exact positioning you're talking about, period. (And half-frames, if you use the somewhat-hidden "nudge" feature.)īut even if you could zoom in closer, the audio waveform wouldn't have any additional detail, its resolution is also capped at roughly the video frame rate. Even if you were to zoom in more closely, you don't have the ability to position clips any more precisely than at exact frame intervals. The thing about the zoom level is, as I've said before, it's geared towards showing you exactly how much information you can make use of.
Maybe the above could be emulated by manually adjusting the Start-End parameters of the audio clip tracks in OpenShot, however I don't know is it precise up to 0.01 or 0.001, that pretty much covers it. That audio has to be unlocked for change by other programs (unlike the usual open files in the project), and only read, not written by OpenShot. (It is similar in VirtualDub)įeature suggestion: Linking audio to external audio tracks and time-sync shifts (as explicit parameters and high precision, not frames). The track is edited outside and is exported to say the same filename, which is linked to the video editor - the editor has a parameter "audio track".ĭuring the preview in the video editor, the editor plays that WAV, with a "Sync" option which shifts the audio clip (one for the whole project), it could be + or - and the precision is in seconds, floating point (not video frames), so such a sync could be done without re-exporting the audio. could be nasty when cutting and concatenating).
One separate audio track in WAV (in order to allow synchronising up to 1 audio sample, 1/48000 sec etc. The suggestion to edit the sound separately in the explanation of the problem redirects me to my self-developed video editor (used only in-house), where I used the same technique:
If I'm not mistaken ffmpeg has been discussed as not guaranted to produce frame-precise cuts.īy the way, do you use the option to show the waveform of the video (if it has audio), maybe it would help a bit. "Shift+← and Shift+→" for adjusting the frames ferdnyc gives an explanation though, technical reasons: #286 (comment)
