Premiere Pro Glitching Videos in Preview and Export - Source Footage Fine

After being sat on 'thank you for your patience' all day on the Adobe live chat, I thought I'd try my luck here.

 

I'm having a recurring issue with Premiere Pro where it randomly decides to glitch my footage. The raw footage has no issues at all with it, completely smooth and no glitching, but when I try to put them into Premiere to edit random glitches start to occur.

 

There is no pattern to the glitches, but once it decides that this part of my footage is going to have a glitch there is no way to stop it, even deleting and re-inserting the footage.

 

I have had a look around online to try and find some form of answer or reason as to why this is happening, and that brought me to two resolutions: delete the media cache files and update Premiere Pro. Well, the cache files are gone and the software is all up to date, but the glitches remain.

 

Now, the oddest thing is that sometimes, in the playback editor, the glitches are gone, and I think the problem is solved. But as soon as i export the glitches are back, right where they randomly showed up. This is hugely frustrating and, after having lost nearly 24 hours on this stupid problem I'd really like some form of answer, solution, or just someone online who can help me sort this out.

 

To clarify: Premiere is up-to-date on my computer, the RAW files are clean, the media cache has been deleted, sometimes I can get rid of the glitches in preview playback, but they are always present in the exported file.

 

Any help on this would be gratefully appreciated.

 

[title edited by mod, raw files are a different format to iphone footage]

So after speaking with the Adobe team I finally got this sorted out. I, like you, am using iPhone footage and it is this that is causing the glitches. I was told that the format of the HEVC footage (iPhone footage) causes Premiere Pro to drop frames and put those glitches into the footage even though the raw footage is fine. These glitches, although you may be able to temporarily remove them from the timeline, remain in the export. Luckily the fix is simple. All you need to do is take all iPhone...

I'm having the same issue, except that I still the glitches on the playback and also as I exported the media out. What type of format are you video files?? .mpg, .mp4?? I still haven't solve my issue... I'm working with an .mov (iphone x footage) and converted to all kinds of formats and still glitching, not and idea what it may be I have also clean the media cache and I'm running the latest Premiere Pro software, restarted my computer and closed all the tabs I had open and nothing..

I was told that the format of the HEVC footage (iPhone footage) causes Premiere Pro to drop frames and put those glitches into the footage even though the raw footage is fine. These glitches, although you may be able to temporarily remove them from the timeline, remain in the export.

Luckily the fix is simple. All you need to do is take all iPhone footage (HEVC) into Adobe Media Encoder and export the file format to H.264 and preset to "Match Source - High Bitrate". The new .mp4 H.264 file should remove/avoid any glitches and solve your issue.

For a project that you've already built, you don't need to go through and redo the whole edit as you can replace the HEVC with the H.264 within Premiere Pro. Follow the steps below to do that:

In the project media panel:

Double click on the HEVC footage so it opens in the source preview panel.

Right click, and select replace footage.

Find the new H.264 .mp4 version of the video and press open.

The source HEVC file has now been replaced with the H.246 file.

In the timeline:

Select the clip(s) of the file that you have used in the edit and highlight them.

Right click, and select Render and Replace.

Don't change any of the settings and press OK.

Leave this for however long it takes (the longer the clips or the more effect editing you have done, the longer this will take).

This should relieve the issue. It worked for me on the one project I tried it on, so hopefully it's a permanent fix.

Another thing the Adobe team suggested I do is change the project settings so that Premiere does the encoding as soon as you load in HEVC files. To do that:

Go File > Project Settings > Ingest Settings

Click the tick box to activate Ingest

On the drop down, select Transcode.

Change the preset to Match Source - H.264 High Bitrate.

Then click OK.

From my experience of starting new projects, this doesn't look like a new setting so make sure you change it every time you start a new project. If that doesn't work, just go back through the steps above to encode the footage before you import it into the project. A bit long winded, but saves time doing it at the start rather than having to go back through at the end and render and replace all the footage post edit.

Hope this helps!

As mrgrenadier pointed out. This issue is related to variable framerate (and the horrid editing codec h265). Getting it out of h265 is great, but with a general transcode you run the risk of burning your variable framerate desync issues into the new file. If you don't need audio sync or if the clips are short it may not be a big deal or that noticeable, but if you are getting desync you're going to need to get your media into a constant framerate prior to any transcoding.

I just wanted to say that I've scoured the web countless times over the past year trying to solve this issue. This rendering glitch happens to me all the time and it drives me absolutely bonkers. I've tried all the tips I've seen everywhere else to no avail and up to now I've just lived with it. Until today. Today I needed to export a perfect, glitch-free video. I spent 6 hours looking through YouTube videos, Reddit posts, Adobe Communtiy, all kinds of other message boards that Google has directed me to, until I stubmled upon this post which I hadn't seen before.

 

And you, aliceh85535058, are the one who hit the nail on the head. I exported my iPhone footage to H.264 High Bitrate, reimported it back into Premiere and hallelujah - it worked.

 

Thank you so much for leaving your detailed tip and curing of my descent into insanity!

I think the optical flow was the problem. This looks like Optical Flow has been applied to the export. This could have happened on the timeline or on the export settings. Change the settings to Frame Sampling (if it's not already.) Otherwise right-click on the clip in your sequence and change it there. If you use optical flow on a 'pre-cut sequence then you will always get these artifacts: Premiere doesn't know about the cuts in the clip and so will attempt to smooth the outgoing and incoming frames by blending them together, giving you the result you see

the danger with this solution is that the transcode will sometimes (if not always) screw up the audio.  Use Handbrake to convert from variable frame rate to constant frame rate while maintaining audio synch.  Hankdbrake's for free.

Just a question about this as I had a similar problem and it was solved by transcoding it through media encoder.. What settings do i use in Handbrake to do this? Media encoder took around an hour to transcode just over an hours iphone footage in 4k, handbrake took a couple of hours.. But if there's less likely loss using handbrake, i'm happy to forgo the time.. Can I use one of the presets to transcode? I was thinking the 'production max' one?

Me doesn't always convert VFR to CFR, weirdly enough. So for that I always use Handbrake.

 

In the video tab in Handbrake, check the CFR circle and set a specific number in the frame-rate box. Then in the compression settings, set them pretty high until it's showing "near placebo".

 

That should do it. And as you can batch things in Handbrake, I typically set it running when I'm leaving the shop for the day or gonna be off the computer for a couple hours.

I had a similar issue. No glitches in Premier when editing, but whenever I export, I would double check the file that was exported and it would have random glitches. Finaly, whenever I export, I used Que, to let it be exported via media encoder, which solved the problem. Was working with Canon EOSR files.

When I transcode it in media encoder, the glitch then becomes engrained in the clip?

I'm having the same issue. Has anyone figured out how to transcode it so that the glitching doesn't become engrained in the clip?

Try updating your graphics card! I was stuck on this for about a week, with hours of scouring the internet and every configuration of settings available in Premiere, but what finally worked for me was just updating the ol' graphics card. Hope this helps!!!!

If you're working with phone footage that shoots h265(HEVC) and variable framerate, you're going to have trouble with it in many editors as they aren't really made to work with Variable framerate footage, and HEVC is the worst codec you can edit with right now. The type of media you work with has a large impact on your editing experience, and this combo may be the worst that exists right now - certainly that is being shot by many people.

 

I personally think of it like a car. You buy a car and then you put watered down gas in it and wonder why it's struggling to operate. For more info on VFR you can look here: https://www.reddit.com/r/VideoEditing/wiki/faq/vfr It talks about it, links to the Adobe article, and talks about solutions.
