why my exported video is glitching at some scenes???

[nabila5EA5]

I'm trying to export a video and this is the third export try..

This video is made from videos that has different fps (24-60) and the sequence settings timebase is 30 fps, and I want to export it to 60 fps so I used these settings below.

Export Settings:

-Format: H.264

-Basic Video Settings: Frame Rate: 60 (unchecked box)

                                     Field Order: Progressive (checked box)

                                     Aspect: Square Pixels(1.0) (checked box)

-Render at Maximum Depth (checked)

Encoding Settings:

-Performance: Software Encoding

-Profile: Main (checked)

-Level: 4.2 (grayed,locked and checked)

Bitrate Settings:

-Bitrate Encoding: VBR, 2 pass

-Target Bitrate: 18

-Maximum Bitrate: 20

-Use Maximum Render Quality (checked)

-Time Interpolation: Frame Sampling

SYSTEM:

I have HP pavilion x360 convertible:

OS: Windows 10 Home 64-bit

Processor: Intel Core i7-8550U CPU @ 1.80GHz (8CPUs), ~ 2.0GHz

Ram: 12288MB

GPU: - Intel UHD Graphics 620 (128MB)

          - NVIDIA GeForce MX130 (4055MB)

note: I did export videos with these settings and I succeed with no problems at all ! But in that video and maybe two other videos I faced the same problem at some scenes..

help me guys please

thank you!

This looks like an issue with optical flow. Are you using optical flow on any clips in your sequence? Namely, the ones showing these?

[nabila5EA5]

No I just downloaded this trailer of super mario and I used frame sampling..

maybe because the videos that I'm using have different frame rate?

[Michael Grenadier · Accepted solution]

any clips that are from screen captures or from smart phones.  than the problem may be variable frame rate clips which are problematic in premiere

use mediainfo to determine whether your source is variable or constant frame rate

if it's variable use handbrake to convert to constant frame rate

and here's a tutorial on how to use handbrake

hello, yeah I'm trying your way now..

I just convert all the videos to 60 fps then relocate them into premiere pro and I'm about to export it.

but I have a question.. should I change the sequence settings to 60 fps too? because I checked and found that it's 30

I'm confused

THANKS!

Problem solved!

Interesting @Michael Grenadier, while I've seen lots of VFR issues I don't recall ever seeing visual glitches like that from it. I'll need to keep that in mind!

[Michael Grenadier]

honestly, so many premiere users are working with screen captures and smart phone footage that it always seems like a good idea to have people who are having problems to check to see if they're working with vfr.    And the screen grab looked to me that it could have come from a screen recording...  elementary my dear watson.
