Video Output Scaling Issues

Hi, Resolve 9.03 lite on OSX 10.6.8 Macpro w/ a qualified BM Extreme HD card woke up this morning not wanting to send out full 1080, and is instead sending a scaled down 16:9 image, more like 720 inset on a black field. Only thing that partially remedies it, is switching from 1080 23.98 psf to 720 59.94, which plays everything at the correct 1080size, but twice as fast. Major problem for clients! Tested sending signals out of FCP, Color, AE at that same setting, all is ok.

I've opened other projects, they seem ok, unaffected, it's just this one project with 3 sequences. Tried restarting, repairing permissions, etc.

Is there a fix or reset?

Thanks

Something else to note, this happens in the Color page. In the conform page seems to be ok, half the time.

It sounds like you must have some sort of sizing adjustment on these clips, since other projects are working.

On the Conform and Media pages, if you select the clip in the timeline, or Media Pool, it will show you the native clip, with no color or sizing information applied. That likely explains why sometimes on the Conform page it looks different. You are probably selecting it on the timeline when it looks different.

Assuming this is the case, on the Color page, bring up the Sizing window, then in the Keyframes area, click on the PTZR enable box, to the left of the Lock icon. Do this with the sizing mode in both Input Sizing and Output Sizing modes. I suspect this will show you where the odd sizing is coming from.

Hi Dwaine, I appreciate your quick reply and the solution as we're under a deadline.

Yes, there's sizing changes through out the project, but there's no undone output /input sizing that's affecting it. Even resetting all sizing doesn't change the issue. It's throughout the whole project. Wish it was that simple!

Here's a shot of the odd interlace it adds. Seems like a pref/config hiccup.

The other odd behaviour is when scrubbing in the conform page, the scaling will jump from normal to shrunken, clip to clip. Then after a few seconds, it will resume the odd shrunkness as previously described.

You mentioned this was an issue in 3 sequences. Is this problem occurring in all the clips in the project? Or only 3 clips? Out of how many?

Do the source clip resolutions match your timeline resolution? If not, the Input Scaling selections come into play, in Project Settings / Image Scaling. If the entire project is messed up, it could be a scaling settings issue.

It's also possible to have input sizing PRESETS applied in the Media Pool, on a clip by clip basis.These changes are applied BEFORE the Input Sizing settings, and could confuse things.

It's also possible in the Media Pool to adjust the Pixel Aspect Ratio on a clip by clip basis. If only some clips in the project are affected, it could be a Media Pool Sizing Preset or PAR thing.

Doubt this would help, but you could try exporting the project, then import it back in with a new name, or in another user, to see if this might affect anything.

That's about all the things I can think of to suggest.

Occurs in all 3 sequences & all clips, most of which are full raster 1080 23.976 psf brought in via EDL & conformed. Been grading on them for 2 days fine until now.

Yes, most everything matches. This occurs randomly in the Conform page on full raster material that matches the EDL/timeline/config settings exactly. It occurs steadily w/in the Color page.

Good thinking, neither was done.

Could this be a database issue? My thought was to reinstall Resolve, but I'd definitely not want to lose my work to date. Can you advise?

[Dwaine Maggart]

It doesn't seem like a database issue. But if it was somehow related, then the export/import thing I mentioned might do something different.

Re-installing Resolve will not affect your existing work. Couldn't hurt to try it. A re-install will not affect the database.

Hi Dwaine,

Thanks for the suggestions. Re-exported project, same thing occurs. Now other simpler 1-timeline projects are inheriting the same issue. Would it help sending a console log output?

Thanks again.
