Transition Glitches after File Export

[jdm73256651]

Software:

Premiere Pro CC 2017

System/Processor/Memory:

Windows 7 Professional (I know)

Intel Core 2.60GHz

16GB RAM

Issue: Transition glitch (as seen in attached image) when using dip to black transition centered (between) cuts.

Where a clip ends and one begins but with a video transition applied. In my videos, most of the time, I typically have 3-5 video transitions. Usually it is only one of those transitions that produces a glitch. They are very inconsistent. The glitch only presents itself appears for a frame or two and at the end of the transition.

Please see the attached image examples that show the issue, settings and attempts to correct the issue. If you can offer help I would greatly appreciate it.

Image 1: Transition issue using dip to black between two cuts.

Image 2: Original Export Settings. It was suggested that I try a lower maximum data rate (6-8Mbps) and/or use two-pass variable bit rate. This did not resolve the issue. 

Image 3: Initially, I did not do this. It was suggested I render the clip before exporting using Sequence>Render Effects In to Out and choose Render Entire Work Area when exporting. Neither resolved the issue.

You say you are using CC2017. Is this 2017.0 or the bug fixed 2017.0.2 ? This may help to fix your problem.

Thanks for suggesting this. I am running 2017.02, V11.0.

One thing that concerns me is that you're shooting and delivering interlaced video for web or computer viewing.  I don't know that's at all related here, but I do recommend changing your production pipeline to 24p instead.  It's just better in every way over 30i.

Run a test as such and see if the issue still occurs.

[Andrew_S]

I've always shot 50i and then exported as 25p or more recently 50p for smooth movement.

[jdm73256651]

I am exporting at 24P at the moment and will update to see if this resolves the issue. Thanks to all who have replied.

Has anyone actually experienced the issue I am referring to?

[Andrew_S]

I'm no expert on NTSC but you shot 29.97i so you should export at 29.97p ? Exporting at 24p will mean premiere has to drop (almost) 6 frames every second.

Great point and the reason I have chosen "Match Source" when exporting.

[excited_Genie16B8]

Match Source is not a great idea.  It's a "big button" option for folks who don't know what they're doing.

Better to know what you're doing and choose the appropriate export settings manually.

You pin pointed me, Jim! I am comfortable knowing that I have a lot to learn which is the reason I am asking for help.

[jdm73256651]

This is interesting... I have discovered this issue/glitch is visible directly within Premiere.

Correction: I had initially described this glitch happening over a "dip to black" transition centered over to cuts.

This transition is actually centered over a title page (still) and the start of a clip and occurs at the end of the transition.

Perhaps this sheds new light.

I am also having a similar issue. Has anyone got any ideas why transition effects would be causing this strange colour glitch on still images? The images that I've applied the effect to have transparency (if that helps any further). I've tried using both png and psd versions for this - but neither makes a difference to the glitch.

Little late to the party, but make sure your sequence framerate is the same as your export. Mine did the same thing, then I noticed the sequence was set at 50+fps and export was 23.978. After changing it the glitches resolved
