relink proxy media links wrong clips

Hello, using 18.1 build 18.
Whan I select several clips and do a Relink Porxy Media, then select the proxies folder.. it relinks many clips to the wrong proxy files. If I do it one by one, it works OK, Any help?

I think I've heard someone else report this in a past release of 18...

Can you post details of the file names that were linked incorrectly - would be interesting to see if there is a pattern. Sounds like a pretty bad bug.

Sure. I uploaded some screen captures, one with the proxies and the other with the originals, and one more as shown by the windows explorer.

Thank you very much

You mentioned that these were relinked to the 'proxies' folder - is that the folder located beside the source media or is that your own proxies folder located somewhere else?

I guess I should have asked first, were these proxies generated via the external proxy generator app? My guess is no because I don't believe that app can generate DNxHR proxy media - so these must have been generated internally, correct?

In that case, what is the path to your proxy folder for these proxies? I understand that you can setup the internal proxy generator to generate proxies located in a proxy subfolder to the source files or to some other path (I haven't tried setting up the internal proxy generator to place proxies in a proxy subfolder next to the source files).

Sorry I'm rambling but I'm sort of thinking this through as I type... lol

Hi..
1) proxies has their own folder, just for proxies, and the originales are stored in another disk.
2) These were generated by Resolve 18.1 build 18. the free version, as specified into project settings, proxy media resolution=choose automatocally, proxy media format=DNxHR LB
3) Proxy folder is D:\DVR\ProxyMedia\ARCHIVOS\FOOTAGE\100MEDIA
Originals are in C:\ARCHIVOS\FOOTAGE\100MEDIA

Great info, Ruben. I just gave this a try with my PC (see signature) running 18.1 (Studio, not that it matters, presumably). I used the same settings as you for proxy generation and performed this task with a series of seven source files. It seemed to work fine for me. Maybe the number of files is the issue?

I did the following:

1. Select all 7 files (in the media pool), right-click and select 'Generate Proxy Media...'

2. Check that each has the 'proxy' badge on the thumbnail. Also checked the proxy file path for each clip using the extra columns in the media page (the proxy path is not shown by default, you need to right-click the column header and select 'Proxy Media Path').

3. Select all 7 files, right-click and select 'Unlink Proxy Media'.

4. Check that the 'proxy' badge no longer appears on the clip thumbnails and that the 'Proxy Media Path' is now empty.

5. Select all 7 files, right-click and select 'Relink Proxy Media...'. A folder selection dialog appears. I selected the folder on my system equivalent to your D:\DVR\ProxyMedia folder (I presume that Resolve knows to look deeper into a folder structure that mimics the source file path, not sure exactly).

6. Checked that all 'proxy' badges and proxy media path were correctly restored.

I'm not sure what is happening in your case, Ruben. Sorry I can't be of more help.

Steve, the procedureyou described is correct. The same thing I did. I actually recreated the problem from scratch , and it happens again.

I'll send to you a link via PM for you to download the original footage.
Thanks for your time. Regards
Ruben

Hi Ruben - I sent you a couple of PM replies. I was able to reproduce this with your media. One thing I noticed is that all of your clips have the same starting timecode (00:00:00.00). I wonder if that is confusing Resolve. Tests with my own media worked but they each have time-of-day starting timecode and are unique.

Still seems like a bug in Resolve... Can you change the way your camera records to have it use a time-of-day timecode?

Assuming this is the reason, Resolve's algorithm for relinking proxy media is poor.

A starting TC of all zeroes can also mean that clips have no TC at all.
That will cause problems for sure.

I agree, however, if you relink proxies to each clip on its own (just pointing to the proxymedia folder location, not the specific file) then Resolve is able to relink to the correct file.

This indicates to me a defect (bug) in the multi-select relinking algorithm.

Thank you Ul and Steve.
I understand the timecode issue. However when you select all clips and generate proxy media it works fine. Also as Steve said, if you relink one by one it works as well. The issue happens when relinking the whole folder. Idk, may be the development team can review the relinking algorithm.
Thanks again

I had this issue the other day, Relinking all m proxies the files from my Drone would not work correctly.

If I went into the Drone sub folder and relink that folder on its on it worked fine but if I tried to relink multile folders in one go the drone folder always relinked it wrong.

It actually relinked the same drone shot across to all the drone shots. So I had a folder of the same drone shot x7 but all had their own unique file naming convention

I am having the same problem with DaVinci 18.1.3.

I recently had to change the location of the proxies and had to re-link them.
I noticed that the same clip was shown twice and realised that it was linked to the wrong proxy.

Problem is that I do not have 7 clips to relink but hundreds. Going one by one would be crazy.
I am worried that now many of the clips are showing the wrong proxies - quite a serious bug.

I read that someone tried to unlink and relink but the issue persisted.
To recap: I generated my proxies through Davinci with "Generate proxy media..." - all was good (I hope...) until I had to change the location of the proxies and then used "relink proxy media..." - It appears that some files are showing the wrong proxies.

Any idea about what to do?

Thanks.

I'm having this exact same issue. It doesn't matter if I generate proxies using DR or the Proxy Generator. If I unlink and relink the proxies, incorrect proxies will get matched to my clips.

One thing to note: I have clips from 3 different cameras in 3 different folders. Two of the cameras' clips seem to work just fine. It's only the 3rd camera's files that are having the issue.

Also, when I relink in DR, it shows the correct files linked for a split second, and then replaces the list with the incorrect files.

Finally, I'm having an issue where synced audio doesn't line up when I use proxies, but that's a different issue. (The original camera audio is fine, but my auto synced audio is off whenever I generate a proxy).

The issue with the incorrect proxies is preventing me from doing a cloud collaboration on my current project, since my editor won't be able to link the proxies correctly.

If the problem shows with one camera only, can it be that camera is not writing proper timecode?
Check if the original clips all start with zero.

Yes, it appears that, by default, batch relinking matches only on timecode, ignoring filenames.

I don't know why this is the way it works. Perhaps a "fix" from when file extensions changed from originals to proxies thus preventing relinking. Perhaps again, ignoring the whole filespec rather than just the extension was adopted as the fix. That might not be noticed if the media had timecode.

Hopefully this will be revisited and addressed, as it's a frequent cause of problems.

Well then, give those clips TC from the start with one of the third-party tools, like EditReady.
Sorry, but clips without TC are really amateur stuff. A Pro would always add TC or even transcode those.

If I were king all media would come with timecode.

I’m not king.

People other than professionals use Resolve. That’s by BMD’s choice. It’s their intention to be in the non-professional market. So why be hostile - either in the program or in the forum - to non-professionals and their very reasonable expectations?

Resolve SHOULD be using the filename to assist with the relink. It’s unreasonable to do otherwise unless the user specifically asks for the filename to be ignored.

Agreed, Joe. Just like you can manually re-conform based solely on file name (ignoring time code).

I didn’t intend to come across hostile, I gave the solutions.
And then, DR is already doing pretty well, reading even the non-standard TC from mp4, if there’s any.
How can the NLE identify clips by name only, if many cameras generate the same names after you change batteries or cards? OTOH, in some cameras you only need to activate TC and proper naming.
A bit of preparation is not asking too much. One day we may have AI that will check the images, but then it may do the editing and grading too

Dumb question, but are there duplicate DJI filenames in media folders?

like DJI_001 in multiple folders?

I don't think this is the issue, but I didn't see this mentioned in the discussion.

Just brining it up just in case someone else reading this thread might be experiencing this.

Yes it’s possible to have duplicate filenames. It’s also possible to have overlapping timecode. Less likely but possible. But we don’t discard timecode because it’s not bombproof.

Plus- matching on filename AND things like clip length make it pretty bombproof. Other NLEs do it and don’t run into these frequent problems.

Just had this today when I relinked 15 DJI clips. Proxies are sitting in a temporary work folder I point all my Davinci proxies to. All the DJI clips are sitting in a single folder. Did all the edits and then went to colour correct which is where I turned off proxies to get maximum res, and boom...all the clips changed.

I activated the extra proxy-path column in the media library and there I saw it...

Clip_0001 Proxy was incorrectly linked to a bunch of clips. They don't even match the length of that proxy so no idea how there is no fail safe that stops a length-mismatched proxy from linking to wrong source media, let alone the difference in name.

Now I have the fun job of re-editing the entire thing

Running into the same issue with clips from my DJI Air2S. Really making my workflow between PC and iPad a challenge. Will keep an eye on this thread for any future solutions

Wow, you're brave to be jumping back and forth between iPad and desktop. That was my goal but the iPad version of Resolve isn't looking very good from my perspective, with no Edit tab, etc.

What's your experience? Shouldn't you just get a Macbook instead of iPad?

Hello,

I am on 18.1.4. build 9 and it seems that this issue still exists.
Has this been raised to BM for attention? Or does somebody has found a solution?
I work with clips from consumer drones, smart phones and small actions cams which usually do not provide a time code.

kind regards
Alexander

They know about it. Hopefully they’ll fix it soon. They don’t tell us of their plans - even bug fixing plans - so all we can do is +1 and hope!

Has this been fixed on 18.5?
I just noticed this bug when starting to use proxies from DJI today...

I haven’t tried it but there was a release note that claimed it was fixed.

Ah, yes I saw that now.
I will wait for stable release and link manually in the meantime
Thanks a lot!

If it's listed as fixed but you find it isn't then it's definitely a good idea to report such! And hopefully keep trying it each time they release a new build.

Just want to answer to this.

How can the NLE identify clips by name only, if many cameras generate the same names after you change batteries or cards? OTOH, in some cameras you only need to activate TC and proper naming.

I personally rename manually (automated, actually) the clips when I import them on the computers. A relink is the easiest of the things, a simple bash script can do that. But Resolve is unable to.. If you are in need of help, any programmer can solve this problem, even for free (pun intended.), just ask.

a very rough sample for the sake of explanation:

for video in <selection>; do ln -sf </new/path/>${video%.*}.<ext> $video; done

In my case,
Resolve fails to relink

SMT-penna-c1-01.mov to SMT-penna-c1-01.mxf

and

SMT-penna-c1-02.mov to SMT-penna-c1-02.mxf

Both get instead re-linked to SMT-penna-c1-00.mxf.
