14.0.0b029: wrong frames in timeline

Hi,

I noticed that I have sometimes a flickering in the timeline, which is caused by wrong frames.
Meaning a suddenly a frame from a different position in the timeline is shown. Only one frame, which produces flickering.
First I thought it may be a problem from the footage, but it is not.

When I close resolve and restart it again, the frame at the timecode is clean again. And others appear.

GTX1060 6GB
Win 8.1
i7 1st gen

Does anyone else have such a problem? Is there a workaround yet?
I havent't tried to render a video yet. So I don't know, if the problem is only in timeline or also in the export.

Thanks, Andreas

What format is the source material? What resolution is the timeline?

i am using mp4 in fullHD with 29.xx fps captured by mobile device.
When resolve asked me to concert project setting to Video Format i approved it. The Rest are default settings.

Can you park on the misplaced frame and do a match frame?

How do I do that?

Scrub through the timeline and park on the frame that doesn't belong.

Then press the F key.

That will load in the source viewer what Resolve believes is the source media for the frame and will also add in and out points to the source media to where Resolve believes are the first and last frames of the source media in the timeline.

I'm facing a similar problem with wrong frames (see viewtopic.php?f=21&t=60140). In my case it's already noticeable in the clips (which play fine outside Resolve) not only in the timeline.

I tested it.
By hitting F it was found. Resolve also shows the bad frame also in source or in media panel.
After restart of resolve, the bad frame is somewhere else.

It is also rendered, when rendering to mp4 (nothing else tested).
It does not matter if I select cuda or opencl. Same issue.

Two questions:

Is the misplaced frame always coming from the same source media clip?

Is the misplaced frame always coming from the same clip that is currently playing in the timeline?

i am using mp4 in fullHD with 29.xx fps captured by mobile device.

I'm betting the mobile device was not shooting at a constant frame rate, and this is causing Resolve to choke.

Convert it to another format like DNxHD or ProRes and see what happens.

can I convert in resolve vor do I need to convert externally?

Pinnavle 16 dies not habe these issues in the same input.
Also I notified that in one clip resolve shows 3 equal frames in a row (here allways in the same media, same Position, even after restart), but pinnavle shows different images at the same time code.

Dont know if this has some coincident.

I would say Bad frames occur in different clips.

Did you have any luck solving this issue? It seems I'm facing the same problem and don't know what to do about it.

Cheers,
Axel

unfortunately not

can I convert in resolve vor do I need to convert externally?

I would convert externally with a utility intended for that purpose.

Andreas and Axel,

If you want to dropbox one of the files, I'll gladly take a look at it.

Hi Peter,
thanks for the offer, here's one of the clips:
https://www.dropbox.com/s/2w0x5t3muvgny ... 7.MP4?dl=0

Frame 00:00:03:07 was just now wrong in Resolve. Strangely enough it's OK after a restart.

Cheers,
Axel

I can confirm I have the same issue.

At first I thought the Beta was having trouble playing back footage in real-time, but stepping through frame-by-frame it has the same issue - either entire frames are skipped, repeated, or I get frames from further back in the timeline.

I assume its a problem is decoding related. Either it has problems with the single clip itself or if different clips have slightly different fps.

I used eyeFrame converter to convert the mobile mp4 footage to DNxHD (dont remember which option in detail). Now all have another format and all have the same fps.

the problem seems not to occur any longer.

So this may be a workaround, but no solution.
Please fix this problem. This would make resolve much better

Andreas, sorry for getting back to you so late on this. Have you tried using a 25 fps project? Using the program GSpot, it says that the footage is 25 fps.

Hi all!
I'm having this same problem where I get "flash frames" in just about any clip. It means that suddenly just one frame from the same clip (but from another time) pops in. These change places. Suddenly they're gone. It's not just in the timeline, it's also in the source clips when viewed in Davinci Resolve 14.0.0b.037 not for instance in VLC media player. Downgrading is not an option since the project can't be opened in older versions. The clips where this happen have a small red exclamation mark in the left hand corner that dissapears if you tick the "Conform Media Clip".
Interestingly enough, if you add markers to where these wrong frames are and change the clip speed - the markers will be at another place in the clip, but the wrong frame will still be where the marker is.
If you change the framerate of the clip, the wrong frame will be at the same place as before, just in a different place on the timeline (since the clip is now shorter or longer).
The wrong frames will also be in the final rendered clip.
If you export an XML and open in Premiere Pro, it will also have these flash frames, but just a red frame, nothing else. This is a very tricky issue.

I used eyeFrame converter to convert the mobile mp4 footage to DNxHD (dont remember which option in detail). Now all have another format and all have the same fps. the problem seems not to occur any longer. So this may be a workaround, but no solution.

That is both the workaround and the solution: you can't use variable framerate material and expect it to work correctly in editing software designed to run at a single speed.

For me this didn't work. I convered the clip to H264 MP4 Profile High (the format you talked about weren't available), but I still have the wrong frames in the timeline with the new clip.

Where are the developers, shouldn't they have figured this out by now? Or at least how to downgrade the program without losing your project files. I didn't know updating to a beta would be such a gamble with all your hard work.

Hi folks,

I am facing exactly the same issue with the very latest DaVinci_Resolve_14.0b9_Windows.zip, and it is *very* annoying. Basically, I've imported a couple of clips, both are in the same format (AVC at 33.6 Mb/s, Aspect : 1920 x 1080 (1.778) at 23.976 fps), and I am getting thin annoying "frame flicker" here and there. When I stop at those moments, I see obviously wrong frame from other location of the clip.

Is there anything (except for re-coding all my video clips in other format) to fix that? How can I trust the software when it inserts random garbage here and there?

I have this issue as well, it looks like problem appears only when using .mov h264.. problem still present in Davinci R14 b9.

He folks, good news (it seems), with the official released version of DaVinci Resolve 14 I cannot reproduce this annoying problem with random out-of-place frames anymore!

Could anyone else who has this issue confirm?
