Stuttering image after export. tried it all

[Frederik358456614jjz]

Hi everyone,

I'm having trouble getting a smooth export on my new laptop, which has high-end specs:
RTX 4080, fast NVMe SSD, and a powerful CPU. The source footage is 4K, and I've applied some Lumetri color correction and opacity effects, along with an MP3 audio track.

The Problem:

The exported video stutters, with images freezing—almost like a slideshow—while the audio seems fine. This issue persists across various export formats and settings.

In premiere the sequence plays smoothly.

What I’ve Tried So Far:

• Exported to H.264 at different bitrates (down to 720p) and also tried AVI uncompressed and MOV.
• Played back the exported video in VLC, Windows Media Player, and transcoded it using HandBrake.
• Tried software encoding only, and disabled hardware acceleration in Premiere's preferences.
• Updated to the latest NVIDIA Studio driver.
• Exported only a small part of the video, without audio or effects (issue still persists).

Despite all of this, the problem remains. Does anyone have any other suggestions or has experienced something similar?

Thanks in advance for any help you can offer!

Convert the mp3 to wave and replace the mp3 with the wav file.

Hi Peru Bob, Thanks for the reply, it improved a bit. The images are not still now. But it the export not fluent at all. It is still stuttering.

Please post screenshot mediainfo

avi uncompressed is not suited for export 

mov is just a wrapper

post screenshot export settings

[Frederik358456614jjz]

Thanks. I know the other exports are not suited, but i tried anyway.

I did the same kind of editing with my previous laptop with a less advanced graphic card and that video worked well. , same source content.

[Frederik358456614jjz]

I thought maybe the HDD is not fast enough to write the speed of the graphics card? The export process is super fast. But even software rendering bugs (without graphics card)

Dont use dropbox but a local drive instead.

It seems that you export to a Dropbox folder. What happens if you render out to your Desktop instead?

[Frederik358456614jjz]

Hi, i exported to desktop and then manually put it on dropbox to share it with you 😉

[Averdahl]

You don´t need to share it with us, you need to playback that file while it still is on the Desktop and see if it works as expected or not. 🙂

Rendering to a cloud folder is often an issue, and in your case the file is being uploaded to Dropbox while you at the same time trying to play it back. That causes issues such as stuttering playback.

Not sure if this only affects the timeline playback (and not export) but have you made sure the Audio Hardware input is set to 'None' in the Audio Hardware settings . Edit/Prefs/Audio Hardware see screenshot.

This solved some stuttering issues I had a while back, but can't remember if it was only on timeline playback or export now.

Worth checking though

[Frederik358456614jjz]

Thanks, I am getting quite desperate, so any tip is very welcome. Turned it off. Stuttering is still there. I tried another part of the scene: https://www.dropbox.com/s/4cgakm72rczylmb/Poetsen%20topshot%20hoog.mp4?dl=0

For all the people thinking i exported to dropbox and this was the issue: no! I copied it after export.

Like I said: i tried almost everything. Next step is to open one source video, trying to export that video without editing . 

Help please!

My thoughts ...

If your source material worked on your previous editing setup on your old laptop then you are going to have to go through step by step trying to eliminate the cause. Its painful but the only way.

1. What processor is the laptop using?. If Intel with an onboard GPU as well, is that enabled in BIOS or not?. Are you using NVidia 4080 for decoding and encoding video?. (Settings in Prefs)

2. Are you able to gain access to your old laptop to run tests on that again or has that gone?. That might help identify an issue with your new laptop, probably drivers or installation maybe. Your NVMe hard disk is unlilkely be the bottleneck as that can write at 2 to 3GB bits per sec.

You could try a complete clean de-install of NVidia Drivers and re-installation if not already done so.

I just checked and confirmed Clean Up tool to remove all traces for new clean install is here

https://developer.nvidia.com/cleanup-tool

Does the Laptop playback other H264 4K videos OK? (not from Premiere Pro)

3. Try 1 video clip unedited then exported. What device did you use to capture the footage?. Ensure it is Constant Bit rate. There is a related thread where Peru Bob suggests using Handbrake to convert variable frame rate footage to Constant frame rate. If you are using a specific Video camera (eg Sony/Canon/Panasonic) then its likely to be CBR.

4. I assume you have done the usual 'Clear Media Cache', Reset Preferences, not using the same project file but start with a new project. Reset Workspace.

5. Try Media encoder to encode the timeline instead

6. Have you carried out a clean re-install of Premiere Pro?

To add ..

Try using Handbrake to encode video using NVidia Hardware (just as a test) to see if that works OK

Also - check drivers on Laptop are all updated to latest. Use Manufacturers website to see if a tool exists to help do that. Most have a utility to check all drivers and update the hardware drivers.

I have found the most obscure faults by trying what might sound like crazy things on my desktop editing platform over the years.
