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

[aliceh85535058]

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.

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!!!!

Um yeah. I need to know why an application suite I'm paying over $800 a year for can't handle a video clip that a freeware app has no problem with.

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.

I tried everything that you have said, but my clip is still glitching. The audio is fine, but the video itself is glitchy.

Veronicar75,

Cute name ... and if you transcoded in MediaEncoder and replaced the file and it didn't fix this, then use the free utility app HandBrake to do the transcode/conversion to CFR. In Handbrake you need to both set a specific frame-rate number (not auto) and check the CFR button, plus I normally set the quality/compression controls to "near placebo" if not placebo to keep from over-compressing the file.

I was struggling with this problem and nothing was working, including this solution. I found a fix for apple users! Open your raw footage in Quicktime, go to File -> Export As -> and select the highest resolution. Reimport this new clip and it will work!

[Forbes5oo]

Thank you so much for this @stephanier55760262 This seems to work for me! 🙏🏻

[jordanashsmith]

This worked for me!!

[Shadrack Booroff]

This is the last thing for me to try. I hope it works.

[Camilla5EFE]

This worked for me as well

So, I have a persistent issue with a particular user who sends me videos to edit, shot on her iPhone (1080p), and they always appear perfect in Quicktime and get glitchy in Premiere Pro. The odd thing is it isn't consistent--sometimes her videos work just fine. Here is everything I tried and ultimately the solution that worked for me...

1. Change GPU settings in Premiere (didn't work) 

2. Convert to H.264 .mp4 file in Adobe Encoder (didn't work)

3. Restart computer and install all updates, then restart again (didn't work)

4. Start a fresh project (didn't work)

5. Load clip into iMovie and export as a .mp4 that way. BINGO

No idea. I'm new to all this, so user error might be a factor. But somehow that silly iMovie trick worked. *shrug*

[fisofiz]

Encoder worked for me.. I'd then try using Handbrake to encode and see if that works.. 

[R Neil Haugen]

For any VFR, it's really more efficient to simply batch convert in HandBrake.   Make sure to both check the CFR circle, and to set a specific number for the frame-rate. Set the compression high enough it says "near placebo".

Do that while at lunch or over night, don't waste your time watching the encode.

Yeah, phone video shoots some of the worst media you can get from the standpoint of an editor or editing software.

1) It's in a bad editing codec: h264 (bad) or h265 (worse)

2) It's often heavily impacted by Variable Framerate.

The combination of these two things (especially when it's h265) creates a lot of playback issues in Premiere. The solution is to correct the Variable Framerate and ideally get it into a better editing codec in the process.

The reason exporting from iMovie fixes it is that the resulting file is constant framerate. The same should happen if you put it in Adobe Media Encoder and encoded it there (although you'd have the option to transcode it into a better editing codec while you were at it). The potential issue with these methods is that it's going to burn in the variable framerate issues like the audio going out of sync over time (unless iMovie happens to correct the audio drift, which would be an interesting thing to learn and wouldn't surprise me too much, since it's all proprietary apple stuff). Assuming that last bit isn't true, I'd approach it in two different ways:

- Do I need the audio in the clip to be perfect/sync'd? Use a solution listed in the link below to correct the VFR.

- Do I mostly just need the video from the phone? Use AME to transcode the footage to an intermediate codec like a lower level of ProRes.

Exporting the file as H.264 worked for me. Then I replaced the original video in premier with the repaired video as per the instructions above. Great work.

[defaultp89v5ovpgcjo]

On Iphone, if you go into the camera section in settings and then go into "format" you can force your device to film in "most compatible" which will only allow you to film in H.264, thereby allowing you to skip the process of converting your videos.

So helpful! Thank you alice for taking the time to write out the steps and your process!

Hi, did you solve this?
I have the same problem and have no clue what to do with this.

[Thiru5E5B]

I'm using 1080p mp4 footage from SONY A7iii + Panasonic GH4 + Sony A7R cameras and premier pro glitches. Super frustrating becuase i've been using adobe premier pro for years and have only recently, within the last month started having this issue. I'm editng on an 2016 Macbook Pro with 16GB Memory and a 2.7GHz quad-core intel i7 processor.

HELP!!! I have deadlines and I keep needing to restart the program after every 10 minutes!!!!

[Michael Grenadier]

did you upgrade recently?  If so, revert to the previous version that was working without issues.  Upgrades often make greater demands on your hardware and 16 gigs ram is not ideal although may be the maximum for your macbookpro.  Also, I strongly recommend you test a proxy workflow using an all iframe format like prores proxy.  It can be a little daunting figuring the proxy workflow but it's been rocksolid for me once I got over that hump.     I'm working on a 2012 macbookpro (with 16 gigs of ram) with  UHD material in a 1080 sequence with pretty smooth sailing using proxies.  

If you have any questions about the proxy workflow, might be an idea to start a new thread.   

And here are some mac troubleshooting suggestions

It's also possible that you're having issues with your storage.   It's important that you keep at least 20% free space on your boot drive and a minimum of 10% on all other drives.  You might run diskutility first aid on all your drives and if you have diskwarrior, running that would also be a good idea.  And you might do some drive speed tests to see if your drives are performing up to snuff.  

Try creating a new user account with administrator priviileges and logging in to the new account and see if that makes any difference to premiere performance.  It's possible some other program or setting is causing issues.   If you have any other peripherals connected besides your media drive, mouse and keyboard, try disconnecting them.  And try disconnecting from the internet either by turning wifi off or pulling the ethernet cable.

Hey i'v been having the same issue since january and tried all the above mentione soloutions and more and nothing seems to work. The glitches only get worse at this point

[Belen5DC4]

Hi! Im having the same problem with the glitching in preview and when exporting 😕 Im using pictures (not video) taken by my iphone but they are not in HEIC format, they are jpeg. My video starts well and after a couple seconds it starts to glitch and freeze. Already deleted cache and its (as i comprehend) not a problem of the format of mi images as the  pictures are jpeg.

CAN SOMEONE HELP ME WITH THIS PLEASE IM GONNA CRY, this is so frustrating. 

Also, I read on a forum that people downgraded to premier version 13 to fix this... Should I try that? idk, help me pleasee

[defaultjnqpgtaqz56k]

What if the file is not an iphone footage, but it's already in mp4?

[Finch1055]

I recently started having the same problem when editing several MP4 files exported from PowerPoint. All I was doing was adding music to the video. The video itself was not changed. However, each exported video seemed to have at least one glitch. Even if I cut the part of the video out that was glitching, it would still glitch. What's so disconcerting is that when playing it back in the Premiere Pro's preview window, no glitch occurs. So, you don't know it's there until after you export. Interestingly, the free version of DaVinci Resolve exports the video with no problem.

The solution seems to be to convert the MP4 PowerPoint video to another MP4 file using Any Video Converter (others will probably work as well) and then using that file in Premiere Pro. The more I use Premiere Pro, the more issues and limitations I find with it. Very disappointing for a professional tool.
