Updated to AE v18.0 Build 39.... Now All My Mp4 Video Footage Imports Are Green?

[kermith85209306]

Since updating to AE v18 all my mp4 files now import as soild green footage?   They also export as green footage in Media Encoder.  These files all worked and previewed fine before updating.   If I rename the .mp4 file extension .mpg, the green goes away and the footage works fine and views  normally?  Having to change the file extension on all Mp4 footage is very inconvient, to say the least.

I have tried completely removeing  and reinstalling AE along with all  adobe products on the machine mulitple times.  Tried going back to previous AE versions with the same result.  All .mp4 files remain unusable without changing the file extension to .mpg?  You can see below the .mp4 file is green in the preview and the same file, with extension changed to .mpg becomes viewable?  Anyone see this issue before or have and idea how to fix? Any help will be appreciated.

I've been having this issue, as well. Rameez's answer did the trick.  Thank you!

today, I opened an AE Project im working on, recently. And all of my imported mp4 (H.264) Footgae wont show anything than a green frame:

(the orange part is a solid layer with an ramp effect. The green rectangles are the mentioned footage)

Last time I opened it up (like last week), everything worked fine. I´ve already updated my graphics drivers but it wont fix the problem. The only thing that changed since I last opened the project is, that I made an Windows update yesterday. 

Does anybody know how to fix this?

[timok71554424]

I think I found a workaround. I just encoded all of my mp4 Footage into .mov files und replaced them in the project. Seems to work. Not quite a solution (After effects should be able to work wit mp4 Footage) but at least I´m able to work on my project again.

Hi there,

Thanks for writing in and keeping us updated. Preview issues are usually related to the GPU. I appreciate that you have updated the GPU drivers first.

Could you share a sample file with us to test? We'll see if the issue is file specific.

Regards,

Shivangi

Hi, thanks for your reply.

Attached you'll find a mp4 file that I used and a screenshot of my preview in AE

[Rameez_Khan]

Thanks for attaching the file here. Can you please try these steps for your MP4 files?

- Go to Preferences > Import in After Effects

- Deselect "Enable hardware accelerated decoding" under Video Footage

- Then go to Preferences > Media & Disk Cache

- Click "Empty Disk Cache" and "Clean Database & Cache"

- Relaunch After Effects and import the files again

Best,

Rameez

Why it shows like this when iam trying to importing a video (mp4). can you tell me a solution.?

[Rameez_Khan]

What are your system specs? Which GPU is installed on your machine? If you could share the driver version, that will be very helpful.

I imported the file on my machine but don't see any green preview. Here is a screenshot:

[CCramm]

I experienced these green frames with imported MP4s as well since the latest update. I did a clean install (trashed my preferences) and the issue was probably caused because the setting "Enable hardware accelerated decoding" was turned back on.

It's probably an issue with NVidia GeForce cards and Hardware accelerated decoding.

[Rameez_Khan]

We're investigating this issue with hardware acceleration and I'm hopeful that the engineers will be able to fix this in a future release.

Best,

When i render out my project as a mp4 file on media encoder from after effects it flickers green on some places so much im almost getting a seizure from it. Im not using any green screen content in my project and it's random, ive tried rendering it out twice and the problem hits different spot of the video in both renders.

Im using after effects version 18.1 and media encoder version 15.1

[nishu_kush]

Hi Argoliz,

This is a known issue. Sorry about that. The product team is working on a fix. In the meantime, please try the following workaround:

1. Go to Media Encoder Preferences > Media.
2. Uncheck "H264/HEVC hardware accelerated decoding (required restart)".
3. Restart Media Encoder and export.

If it doesn't help, try exporting directly from After Effects.

Let us know the results.

Thanks,

Nishu

Hey, sorry for the late reply

Your solution worked, much appreciated

[Rameez_Khan]

This green preview glitch in After Effects 18.0 was related to a bad driver that got fixed.

If you're experiencing this issue in After Effects 23.0, it might also be due to a bad driver configuration. Please see this discussion for more details:
