Davinci is pointing media offline, but they are there! Don't find them!
on Oct 1, 2019 at 2:14:05 am

Hello guys!
I have an offline media issue with Davinci Resolve.
I synchronized the files in Plural Eyes 3.5 and exported it to Final Cut Pro 7 XML.
In Davinci Resolve, I imported an XML timeline.
OK, most of the files were imported and placed correctly in the timeline, but some files from my Canon 6D were also placed correctly in the timeline, but are showing as Offline. These files are 1min or less in length. However files with longer duration appear normally.
All are in the same folder.
The other cameras and audio files are all showing up and being imported normally and correctly.
What do you think it can be?
In the screenshot, in red, are the missing files.
(Apparently Davinci is importing the video file as an audio file....)

Is this free Resolve or Resolve Studio? The latter supports more formats than the former.

Generally, all the DSLRs out there shoot H.264 files, which is not a great format for post. My general advice for DSLR workflows is:

1) organize all the files by shoot date and camera card number, so each file folder would be A1_03112019 [and so on]

2) add a unique prefix to the heads of every file to create easy-to-understand file names (like "A1_03112019_C0001," "A1_03112019_C0002," etc.)..

3) transcode all of these Long-GOP H.264/H.265 files to a high-quality codec like ProRes 422HQ or DNxHR, and keep the file names and folder structure exactly the same

4) archive the original files somewhere safe, just in case

5) do the entire edit with the transcoded files and consider them "the new masters"

6) now, when you do the conform in Resolve, every file will have a unique file name and even though the camera timecodes will still start at 00:00:00:00, there will be no conflicts because of the file names.

7) it helps greatly to have the editor create a reference file that has visible timecode and filenames for source files, as well as record timecode for the project itself.

Variable speed changes are a problem for all edit systems and cameras, because there is no simple provision for variable framerates in XML (plus different playback methods like frame-blending or optical flow produce different results). One way around this would be to just export the variable frame-rate clips and consider them a self-contained VFX shot. The alternative (which I have done) is just to manually varispeed the clip within Resolve and eyematch it to the reference video created by the editor.

This is a proven workflow that can work. I'm not a fan at all of productions using cheap cameras that have no internal jam-sync timecode, because inevitably there's also other problems like exposure issues, sound problems, and other things that basically come with the territory. But I get that not everybody can use an Alexa or a Red camera, and sometimes you have to deal with what's there.

There is more to it, but I I would point to the following books as fairly thorough references on the subject:

Thanks for reply Mark
It's the free version.
I really don't have enough resources for better cameras and complex systems. Until a few months ago I was using Sony Vegas to edit my events.
Now I bought a 2019 Macbook Pro and decided to install DaVinci Resolve. I really liked the software, but I'm just having this problem. See, the files from all the other cameras I've used, even simpler than 6d, worked fine. even other 6d files worked fine. I really don't know what's going wrong that he's not considering/finding these files when importing the XML project.
It says that could not be found more than 100 files in the folder, but they are there.
and I can't select to have the offline file replaced with another one.
The Offline files, although video, is appearing as audio.
The topics 1 and 2 I already use that.
Should I use DaVinci to trancode the files? (Topic 3)

are the 6d files the same frame rate that you edited at, or was a frame rate conversion being done during the edit?
