PlayStation 5 gameplay (.webm) Converted to .mp4 Has Flashing/Strobing Artifacts

[edepot]

Problem description:

PlayStation 5 has feature where it will capture gameplay if you press a button. The captured gameplay video is in .WEBM format. Converting the .webm video to default .mp4 using Handbrake shows flashing strobing artifacts in the converted video: https://youtu.be/kfla2im3Smo

HandBrake version (e.g., 1.3.0):

1.3.3

Operating system and version (e.g., Ubuntu 19.10, macOS 10.15 Catalina, Windows 10 1909):

macOS Big Sur (11.0.1) Intel CPU

Error message text and/or screenshot:

Converted handbrake video showing strobing, flashing problem uploaded to YouTube: https://youtu.be/kfla2im3Smo

HandBrake Activity Log:

It affects ALL PS5 .webm captured gameplay videos converted to .mp4 (using default settings).

[sr55]

We'd need a sample file from source to look into it and a full activity log.

None of us have PS5 so we have no way to replicate this.

[edepot]

Here is the activity log. The file converted is called ASTRO's PLAYROOM_20201124200740.webm That .webm files is huge, multi Gigabytes. Are you sure you want me to upload it?

You can make a small recording and then upload it.

[edepot]

Is there an option in Handbrake to just convert a few seconds of the video? If yes, how do I do it?

[sr55]

It's a sample of the input file we need to reproduce this. Not an encoded sample.

If you could record a few seconds of random gameplay that reproduces it, that would be ideal

[Shakil-Shahadat]

Devs need a sample of the input, apart from that, you can convert a few seconds of the video by selecting range to seconds.

[sr55]

We've not heard back in a while so we are closing this issue out. If you or anyone else can provide an input file (i.e. a short clip of what PS5 exports), we can look into it further.

Thanks

[edepot]

Why was this closed? Please at least allow time for people to respond. I figured out the problem that was causing the flashing... It was the default deinterlace filter being on. I turned it off and it no longer flashed in the final conversion. Please let the developers know that there is a problem with the deinterlace filter (the default settings when you run the program). The solution (and bug fix) is to turn it off for now until they get to the bottom of why it has a problem with PS5's default gameplay save format.

[bradleysepos]

It's no problem to reopen. Thanks for the feedback. It would really help if you could provide a very short sample so we can reproduce the issue here. Thanks again.

[sr55]

@edepot - Several weeks passed without a response and since we have no sample file and no evidence of any problem in HandBrake that we can track down the only thing we can do is close. As I stated above, "If you or anyone else can provide an input file (i.e. a short clip of what PS5 exports), we can look into it further." which we can do if a file is provided.

Either way, we still need a sample webm file from the PS5 otherwise there is nothing for us to look into. It could well be the PS5 is producing a non-complaint or broken file in some way but we can't know this without looking at it.

[sr55]

One final call for a sample file. If we don't have a recorded sample from the PS5 to check out, there is nothing more we can do here and I'll close this out again until such time a sample appears.

[ChadMaverick]

Hi, I have a raw .webm file that starts flickering when I convert it into mp4 with Handbrake, whats the prefered way of uploading the file to you?

[Edit] added it to easyupload.io https://easyupload.io/iezsly

Example of converted mp4 video https://easyupload.io/pi5a9z

Do tell if it should be uploaded somewhere else

[galad87]

Can you try a nightly build? https://handbrake.fr/nightly.php I can't reproduce it in the latest one.

[ChadMaverick]

Hi @galad87 there is no issue when I use the latest nightly build. used this one and the output looks fine
