Videos Exporting with black speckles and graininess?

[defaultgfjur6x5tq1l]

I've exported this a couple of times now, and I keep getting these random black and white pixels and some black, blurry smudges through the video. This is my first time using video footage from the DJI Osmo Action 5 (was previously using GoPro Hero 9), but the raw footage is nice and crisp and I can't understand why Premiere Pro is throwing these black smudges and grains around.

On the underwater screenshot, there's the black smudges throughout the footage. The water was far from clear, but these black smudges are being added. In the screenshot, you can see a blackness just off from the centre, up the top, and on the right. Hard to notice without watching the footage.

On the second screenshot, you can see all these little black and white pixel specks.

These specks and blurs dance throughout the video. I tried modifying the export settings, but keeps happening. Premiere Pro did update to 25.1 halfway through editing the video (and I had to make a new file for new version). Really hope it's not the new version that caused the issue, as I've spent most the day editing the new file version before noticing the corruption on export. I can't see the corruption in the preview pane while editing.

Export settings:

Format: H.264

Frame Size: UHD 3840 x 2160

Frame Rate 59.94

Field Order: Progressive

Aspect: Square Pixels

Turns out I can see these weird blips and pixels in the preview, I just have to enlarge it.

Have tried removing files from Premiere Pro, adding them back in, then re-inserting them into the project timeline, and the issues reappear. The original video files don't have these issues outside of Premiere Pro.

No matter what I do, these black shadows keep appearing in Premiere Pro on DJI videos. I tried importing an older GoPro file, and it seemed not to have the glitches. Tried another DJI clip from another day, and it seemed to have the glitches again.

My video filming setting on the DJI Osmo Action 5 is:
Resolution 4K 16:9
60FPS
Rocksteady+ Ultrawide
Auto Exposure
AWB
D-Log M 10bit

The video files made look amazing just loaded straight up on the computer, but get really glitchy in Premiere Pro. This is my first time using these videos in Premiere Pro, so can't confirm if it's just 25.1 that can't load them, or Premiere Pro in general.

I've since purchased a HEVC Video extension, cleared the cache a bunch of times, and tried a bunch of in app fixes that haven't helped with the issue.

Do you have a short original clip you can upload (to google drive, etc) for us to take a look at?

In the end, I couldn't get Premiere Pro to play nice with files from the DJI Osmo Action 5. No idea if this is poor connectivity with Adobe or DJI, or a bit of both.

After lots of Googling, I've noticed that DJI and Premiere Pro have had plenty of issues working together in the past and that a common work around is to convert the file to a different type without changing any of the parameters. Bit of a pain, but there is a free program called Shutter Encoder that, I believe, keeps the file quality high while letting Premiere Pro utilise them without glitching them up.

For anyone reading this with similar issues, I hope you find this before doing a bunch of editing to your work! If not, this is what I did that worked: Converted all the used video files as .MOV into a new folder, deleted the original video files, loaded the Premiere Pro File, it then showed the files as missing, so I located the new files, and everything seemed to fix itself.

I did notice I missed a single file. If anyone wants to look at the part that wasn't converted, its between 8 and 12 seconds on this video (ignore how dirty the water is, you'll notice the random black glitch blossoms that Premiere Pro added): https://youtu.be/MSda3oWQcqw Previously, those glitches were over the entire video, as well as random black and white pixels showing up randomly.

Hi,

The reason is that your computer is probably not powerful enough to handle these highly compressed files without transcoding or creating proxies. It sounds like they are 10-bit 4:2:2 files at 4K HEVC. Some of the newer computers from Apple can handle the Long GOP files, but standard PCs, even powerful ones will not be able to handle smooth playback of the native files. I hope the info helps. I recommend that you use ProRes to maintain the 10-bit 4:2:2 quality.

Thanks,
Kevin

Good solution. It's been mentioned on this forum to always transcode h.264/5 files into an better for editing codec like ProRes LT or even Proxy. You can easily experiment with this using https://www.shutterencoder.com/en/

Proxies also work well in PP, but if you are of the mind to transcode, that's going to be a very good solution. Well done, glad you got it all working. 

What format did you transcode into?

[defaultgfjur6x5tq1l]

I initially just put it through and kept it as .mp4, but I did read it's better to change to .mov. Regardless, putting it through Shutter Encoder seemed to please Premiere Pro.

Would be nice if Premiere Pro were to get an update to accept the DJI (Osmo Action 5) files without issue. It does seem absolutely bizarre that what's currently considered the best action cam right now and the best video editing program don't intergrate smoothly together.

Hello. I am having this exact issue as well. I had almost completed my 1 hr and a half project. Several clips I had used were from theDJI Osmo Action 5 Pro. I think this glitching should already disqualify the use of word "PRO" onthis camera.

I have footage from two GoPro cameras, I Phone (Raw), DJI Drone, some from a Sony mirorless, and about 20 minutes from the DJI Action 5 Pro.
The sequence settings are 4k - 30fps. I have differnet fps footage clips, which I have never had issues with before.

All is good when editing, and viewing before rendering.
When rendered, the clips from the DJI Action 5 display the glitching (Grainy frames)

I have been communicating with both Adobe and DJI team. After a few days of back and forth without success, I have stumbled on this exchange. 
I went a head and got the shutter encoder. I then selected one of the footage clips and converted it to different files. I tried MPRG, and MOV, but I am getting the same issue.

I don't know what else to do. I am so mad at trusting the camera and using it on a serious project. I am really surprised they did not use the same technology from the drone cameras witch is exceptional in both compressed and raw modes.
In any case, I will keep trying to convert to other extensions with different settings and see what happens. If anyone has an idea what I can convert to that footage, please let me know.
Also, another super annoying thing the DJi Action 5 did is splitting the video from the audio. After converting the footage, I think I am going to have to time every clip I have on the sequence manually to match the audio.

"defaultgfjur6x5tq1l", thanks for posting your comments.

Alright. I got it figured out now.
The conversion that worked on Shutter Encoder is: H.264 / .mov
I am have about 4 hours of footage worth converting, then I will replace the footage in the Source. the funny thing now is that the sequence segments with those clips don't seem to need rendering. They don't show the yellow line in Adobe Premiere and nothing happens when I render. I exported a clip just to make sure it is working fine and it looks good. I hope this helps.

The H.264 mov is exactly what I used. Apologies for not popping that into my comment before, but glad you figured it out and shared the answer.

If you get better answers from Adobe/DJI, please update us on this thread!
