Avi video files don't play

[F31911627hlee]

Yo, friends. I have a ton of MKV files. I used just rename the extension to avi and edit the files using Premiere Pro 2020. After I decided to upgrade my system to Msi z790-pro, 13900KF and RTX 4070 Ti (64 GB DDR5-6000), it simply does not work anymore. Files are imported, but videos don't play. Just sound works. I don't understand what changed. I can use MkvExtractGui in order to import just videos, but I feel like I just trashed my money away. I installed official Adobe Premiere Pro 2024, but it's the same. Videos play smoothly when I open it with Media Player Classic, but it's impossible visualize the same videos in timeline. I had a 11400F with Aorus B-560 m and RTX 3060 before. I still use the same Windows 10 64 and the same K-lite Pack. 1 week ago, I just had to rename the files extensions to avi and the video and the first audio stream would play perfectly... I tried several things, but now it's impossible here. Is there a way to make it works again?

Thank you very much in advance.

Premiere does not support mkv.

You can write a feature request for this.

Ann, I know Premiere does not support MKV. But renaming the extension to AVI always worked with Premiere 2020. After I did this system upgrade, he same videos thar used play smoothly with the older sysrem until 1 week ago don't play on the same Premiere anymore. Videos don't play on Premiere 2024 neither. I don't understand what changed. I think making a request is totally useless. Adobe does not care. I thought some expert friend here would know...

Make sure to use the latest Studio Driver from NVIDIA (NOT the Game Driver).

Using the latet version.

For sure you must know that renaming files was not a permanent fix. 

Try Shutter Encoder to convert the files (before editing). Maybe try ProRes LT or even ProRes PROXY format within Shutter Encoder for easy to edit formats with 'better' files size.

 It was working for the last 3 years. I just did an upgrade and it happned. I can't help thinking there is some new "element" (external to Adobe) that caused this problem. 1 week ago, I just had to rename the extension...

I know Shutter Encoder. Thank you very much. I would rather use MKVExtract Gui in order to use the exact same video file wihout reencode.

I can't accept this alteration without an explanation...

Has nothing to do with the gpu.

Premiere changes over time: It under the hood.

Thank you very much, Ann.

Did you manage to find a fix? I'm on the same boat, almost 3 years renaming .mkv's to .avi, and worked like a charm. Idk if my system got an update lately or something, on 2020 those files cause the program to freeze, and 2024 just looks black. I'm somehow desperate to edit something right now 😞

The latest beta 25.2.0.6 supports MKV.

I see this note on build 6: Enable support of H.264 streams in an MKV wrapper

So, webm / vp9, still do not work, right? I'm not sure I've seen mkv h.264
