Ghosting or Fields Error on Pro Res Export

[Guest]

Hi,

I am trying to export using Apple Pro res HQ or LT and am currently seeing ghosting/field issues on the export.

I've turned Max depth and Render off and tried it but same problem. I've made sure all settings are the same on the sequence and the export.

I've even changed it from CUDA to software only encoding and its still there.

I've watched the exports through VLC and Quicktime and I'm seeing the issue.

If I re-import the exported files into premiere, they look great, no issue.

Any thoughts?

Specs:

Intel(R) Core i7 - 7700K, 4.20 Ghz, 4 cores

NVIDIA GeForce GTX 1070

Thanks

Ghosting and or field issues can be caused by problems with video drivers, improperly interpreted footage and many other issues across both hardware and software. A few questions for you:

• Is all your footage from one source (camera) or are you mixing footage?
• What is the original camera format(s)?
• Does your sequence look good before the export?
• Would it be possible to take a screenshot of the issue you are talking about?
• Also, would it be possible to take a snapshot of your export settings?

Camera Footage Issue: Whether you are working in an SD project or an HD one, and are using footage from a ripped DVD, or footage from cameras like Sony/JVC HDV, P2, Varicam, HDV100, etc--you can be running into field issues. Field issues can happen while you are editing or just appear on export if the footage hasn't been processed correctly. Before editing, you can RIGHT-CLICK on your camera media in the PROJECT WINDOW and go to MODIFY > INTERPRET FOOTAGE. Click on CONFORM TO and then choose your FIELD ORDER. For typical SD (Standard Def) footage you would choose LOWER FIELD FIRST under FIELD ORDER. High Definition interlaced footage like 1080i generally uses UPPER FIELD FIRST. For everything else, like graphics and progressive HD, UHD and DCI footage--you would choose NO FIELDS or PROGRESSIVE.

If you aren't using any type of interlaced footage, it's possible there are some weird settings or encoding issues causing this. Corrupted display or codec drivers, etc.

Hi,

So

• Is all your footage from one source (camera) or are you mixing footage?  Same camera footage. Its all shot on Canon 5D Mark 4 and 3. Same settings on all of them.
• What is the original camera format(s)? I believe it as 50fps 1920 x 1080 ALL-I on the cameras. Or it was 25fps...
• Does your sequence look good before the export? Yes
• Would it be possible to take a screenshot of the issue you are talking about? See Below
• Also, would it be possible to take a snapshot of your export settings? See Below

It also has the 8 -bc checked, but i couldnt get it in the screenshot.

Please post screenshot export settings with left tab open to output with visible image and

screenshot clip properties taken with MediaInfo windows / MediaInfo Mac in treeview.

Ok so I'm pretty sure the issue is that the clips causing the ghosting are sped up.

My only though in regards to that though, is that this doesnt usually happen. I speed clips up all the time, and never see this ghosting effect.

Thoughts?

MathewT,

Your sequence settings are set up for interlaced video. You have progressive source media. Match your clips settings to the sequence settings by dragging a representative clip to the New Item icon. You can also switch sequence settings to a progressive frame rate.

Please try one of those things. Let us know if you need help.

I changed the settings but the issue continued.

As I said in a previous post, I think the issue was basically the sped up footage.

I changed all settings to optical flow, and it appears to have lessened/solved the issue.

Thanks for the help!

I see the interlaced lines. I see the incorrect settings. Try deleting preview files and then take another look.

That's me right now.

I deleted the render files, and BAM! Success!

Thanks so much for all the help.

[Kevin-Monahan]

YES!!! Nice work, sir.

Uncheck max depth, max render and composite in linear color.

Did you set the VLC player to de-interlaced because you are watching it on a computer screen which is progressive.
