Cant trim clips after music added?!

Hope you can help:

I have added and trimmed some clips on the timeline, about 10 minuts all in all.

Then I added four musicfiles to the timeline.

But now it suddenly no longer possible to trim the length/fix enhance/acces tools/edit audio of the majority of the clips on the timeline. I'm not sure when this change occurred, or if it is linked to the added music, but it is really annoying... since I cant edit the movie from now on.

If I unlink the individual clips from its audio I can trim and modify the movieclips - but I'm not interessed in that, since it just leaves me with a problem about the remaining audio.

Anyone who can help? It would be greatly appreciated :

Hi FNUSNU, welcome.

I know this might not solve your problem, but I had a similar problem a few weeks ago.
The problem disappeared by itself within two days. I had not either updated anything or installed anything new that might have influence.

The only thing I did was I removed all music files both from the time line /- lines and from the Project Library - saving the project - rebooted the PC - opened project - imported music files to the library - saved the project - placed the music files on the timeline /- linies.

The above, I did twice.

And, waw, now all worked as it should.

Hello, FNUSNU!

Another way of tackling the problem might be to render(that is, produce) the clip you have put together then make your edits on that new clip you've just produced. If you've spaced out your music sufficiently that no overlapping occurs between each music track, you can make your edits in the spaces in between the music-backed segments.

Cheers!

Neil.

Thank you for your replies!:

Anja: Tried your idea, but unfortunately with no effect.
Neil: Wont that effect the resolution-quality, that I re-edit after the produce? It is also a bit hard, if I want to sync specific moments in the clip with specific beats in the music, i think. But perhaps I'm just not getting it, Neil :
bonagege: It is standard MP4 taken with Gopro.

It is a bit weird that I kan unlink video and audio, and then edit both separately, but when I link them it is not possible...

I'm quite convinced that it is because I cant re-link them again proberly, because the clips that I can edit has a small dotted line between audio and video, but the clips I can't edit, has a hard black line dividing them.

Hello, FNUSNU!

Firstly, Bonagege was referring to audio files rather than video file types when he asked about MP3, he was asking what type of audio file your music was recorded in.

As for resolution or quality, because you're working in digital media, there's no loss in either. It doesn't matter how often you re-render, the only thing that may shrink is the file size of your clip(by a few megabytes) Re-editing will not affect picture quality either, for the same reason, you're working in digital media.

Cheers!

Neil.

I'm afraid that's not correct. Unless you are working with lossless codecs (like MagicYUV), there is the potential for a loss in quality each time you produce. AVC and HEVC are lossy codecs and when you produce to them your content is encoded slightly differently than it was when it was recorded. If you produce using SVRT, then all unchanged frames are simply copied to the output clip and no rendering is done.

FNUSNU, can you attach a screenshot of your timeline so we can see why you can't edit your clips? Please use the Attachments button from the main text editor so we can see a full-size image.

Neil, I should clarify that you are correct that when making copies of digital media, whether audio or video files, there is no loss no matter how many times a copy is copied.

However, when it comes to producing/rendering media, the content changes every time a clip is rendered UNLESS you are using SVRT or a (mathematically) lossless codec. Most of the changes will not be noticeable, but the goal is to keep the number of renderings to a minimum so you don't get the digital equivalent of xeroxed copies of copies.

Hi, Optodata!

Well, that's one on me! I thought, because we're working with digital media there would be no drop in quality regardless of how often an item is "rendered". It's natural for losses in editing(chopping out unwanted bits) but the picture quality should stay constant. That's supposed to be the attraction of using digital media in the first instance. It was vastly different when all we had was analogue videotape.... any more than one generation away from the "master" and the image became unwatchable.

Cheers!

Neil.

P.S. Something I have noticed in rendering with SVRT is that the overall length of a finished clip is shortened, as against hardware rendering or viewing the image while rendering. The SVRT method causes a shortening, not by much, just a frame or two, but enough to throw out the work I do in editing where I count off frames before splitting the clip so that I can make a video that is meant to run for an exact number of minutes and seconds with no "spare" frames.

Thank you for your responses. Well, as mentioned, I identified the unlinked audio from video as the problem. It is probably extremely simple to fix it, most likely a feature or function that I just havent been able to locate due to lack of experience.

I have attached a picture of the timeline. The clips I cant seem to link again is marked red. The clips marked blue are linked, and I have no problem with editing those.

Can you guide my to the (I'm sure very simple feature) where the audio and video can be linked together again? :

FNUSNU Your clip and explanation show very clearly what you're experiencing.

This is very similar to a bug in PD12 that took a long time to understand and fix, but if you watch this *video* you should be able to fix the issue. If you are in a hurry, you can skip to about 2:20 to see how to tell if this is the same problem, or go right to 3:45 to see how to fix the split clips.

Please ignore all the technical details onscreen regarding PD12. The main point is to learn how to restore your broken clip. Please post back and let us know if that helps or not!

OPTODATA: Thank you for the link! It seems like I have a similar problem. But I can tell from the video, compared to my problem, that when I try to re-link the audio and video, as shown in the video, the two parts just does'nt fully merge (shown with the dotted line between them, and not the fully dividing black line). They can be marked blue as one, but just not fully merged...
Strange!

Two suggestions: Try aligning the start of the clips. Sometimes the problem is at that end instead/as well.

Second, make sure that you select both the audio and video sections of one clip at a time and try the Link audio and video tool as shown in the video. It will not work if you have sections from multiple clips selected, and it won't work if either end of the A and V are sections are not perfectly aligned...

Problem solved. But pretty demanding work. It was, as you said, optodata, the right way to start with the beginning, unlinking audio and video in every clip, adjusting audio and linking back together. Quite time consuming. Hope it does'nt happen again! Thanks for your advice.

I have attached a picture of before and after the procedure.
