At present, this problem has not been solved. This situation is simply disastrous when doing sound effects and some work that requires very careful alignment of a certain frame, because the files sent always have a slight deviation from the editing software. If all DAWs were like this, I could tolerate Steinberg’s inaction, but I tried Logic and PT, and they all worked very well!!!
Thank you very much, but this is indulging Steinberg’s inaction. First of all, I cannot demand that every video producer export prores and pcm audio. Then, as I said, there is no problem placing the same video in another DAW, and the whole thing is undoubtedly Steinberg’s mistake.
Okay, thank you very much. I carefully read every word, understood the reason for this problem, and understood why Steinberg did not correct the “so-called error”. However, it was frustrating that I sent the same video to my friends using Logic, and they did not have this situation - the beginning and end of the video and audio were aligned, If possible, I really don’t want to know what caused this result, but the current situation is that in the opinion of the video producer, the software I am using has some issues in some aspects
Alas… I was really annoyed when posting the theme, and I sincerely apologize for the unreasonable title… But I hope to see experienced people say that setting something in Daw can avoid such a result. I mean, I don’t want to know why, I just want to know how to do it and it won’t be like this
Thank you again, Fredo. I think I understand the problem. What I need to do is ignore the audio that is imported with the video every time. In other words, there is no problem with the length of the video. The problem is the audio in the converted video, so I can still keep in sync with the video producer. My initial concern was that there was an issue with the video length in Nuendo, which would be very bad…
Well … I think even that is possible.
Video compression for dummies:
A full frame video is build out of frames: 1 2 3 4 5 6 7 8 9 10 11 …
An mp4 video has fewer frames: 1 . 3 . 5 . 7 .9 . 11 …
Compression drops frames which are later “recreated” by the computer upon playback. ( 2 4 6 8 10 …)
The more a video is compressed, the more frames are dropped and the more frames that have to be rebuild by the computer, based upon the remaining frames. That’s why the quality of the video gets worse and worse.
These recreated frames are (calculated) guesswork. Which means that if these dropped frames contain a doorslam or other sync-critical image, after calculating, it can be a frame off. Or more.
Same goes for the length of the video. If many frames are dropped at the end -or beginning- of the video, the computer might not be able to recreate the last one. The same issue happens with some mp3’s. (Last few frames are not played back)
I am confident that most video creaters, compressors and playback systems have the technology that prevents these artifacts. But as with the issue of the embedded audio, you never know.
And that’s why BITC is another important requirement in video delivery.
