Sony FS7 MXF drop out at cut in point

Hi.

I work now on TV show where some material is shot with subject.
I get on every delivery render at least 1-5 dropouts on cut points.

Local.GPUPinnedHost.Enable = 0 does not help much.

Here is the screenshot i usually see. Patern might be different but it still is broken.

Is there any way to fight it somehow ?

Win 10 Pro, i9, dual Titan Pascal, latest Resolve version 15.1.2.008
UHD timeline or HD timeline give the same results.

It happens to us occasionally, and has for a long time. I’ve been fighting the bug for years. I think it has something to do with how Resolve reads the XAVC-I footage.

I’ve seen it happen on an NVIDIA 9-series TITAN X on a MacPro5,1, dual AMD FirePros on a MacPro6,1, as well as a NVIDIA 1080 Tis on HP Z8s running either Windows or Linux.

Usually on the Z8s, if we’re still just scrubbing through the Color page, grabbing the playhead and scrubbing back over the problem area, forcing Resolve to read the file from disk again, we can get the correct frame.

However, if you’re running into the problem during renders, my bulletproof workaround is to just cache the source [now “Fusion page output” in 15] to a good DI format. On a Mac, use ProRes 4444, or on Windows or Linux, use DNxHR RGB 444, and check the option to used those render cached images on the Deliver page.

Yep, same thing here with FS7 footage; occasional green or purple flash frames. As Seth mentioned they can be got rid of fairly easily, but it is frustrating as we have to be constantly on the look out for them.

I do the cache render every time to be safe as it helps to eliminate those more.
Another way is to extend cut point under another shot and let cache re render that clip.

Loose so much time on long form work that is getting super annoying.
