No, it cannot be opened directly within Vegas. Nor can it be opened within After Effects. It has to be converted........Handbrake is what i easily use as a free solution.

Could you post Mediainfo report of one of your files and tell us which camera or capture device created the file?

As Webm is a Google project, most files are downloaded, often VP9 from Youtube.

I don't know why, but editors don't support Webm, but if Vegas did, it still wouldn't open due to the VP9 video within. A more realistic compromise would be if Vegas supported MKV containers containing VP9 video the way Davinci Resolve does, then instead of re-encoding you can quickly rewrap to MKV, or download the MKV version. In case of both editors the audio has to be re-encoded, but that's easier and less problematic as far as quality loss with re-encoding video

Why neither NLE's play Opus audio is another mystery

484 kb/s at 1080 fps

I looked at my oldest consumer camera that I ever used to shoot video. It recorded at 15 Mb/s

Frame Rate Mode: Variable

Another fly in the ointment for anyone who is serious about video.

You won't get any support from me for the Vegas Pro developers to implement webm decode or encode. If you really want to do it anyway. Happy Otter Scripts Import Assist and Render Plus allows you to do it within Vegas with no drama.

Yeah, but it'll get 8k to stream on the internet, which is no small trick. It will also be used (maybe a lot) when ATSC 3.0 is in every US market. HEVC (.h265) is at least as compressed, maybe a tad smaller in the bits-vs-quality game. And AV1? It's just plain ridiculous; maybe 2/3 the bandwidth.

@Musicvid

You've made the case for webm as a delivery format, not as acquisition or intermediate.

Absolutely agree. Unfortunately, much of what we call "acquisition" is done over the internet, not from devices or physical media. I've had a tough time getting used to it,

I have a very specific use case. I'm using a web-based, screen capture application to record work meetings. I then would like to edit them sometimes. I have no control over the bit-rate in this application. I can tell you though that the recorded Webm videos look exactly like the original video quality during the live meetings.

I've had a tough time getting used to it,

Yeah . . .

What is the application? It bears testing, as we're snowbound this weekend.

It's able to achieve this due to variable frame rate, if there is nothing that needs updating it doesn't update the frame, and VP9 has better compression than h.264.

But back to your problem, There's no easy fix for Vegas, you must keep doing the full re-encode if you wish to edit, if all you want to do it simple edits and cuts then you could use the free version of Davinci Resolve after rewrapping and converting audio(fast, and no reduction in video quality). To do that using Shutter encoder looks like this

It depends on what your motive is. If you're trying to do a quick edit in least possible time, use Resolve, but if time isn't the problem, you're just annoyed about having to do a full re-encode on hours of materials that's a different situation. You just want to be heard. I don't think NLE's will ever import webm, but maybe Vegas will import VP9 within MKV container in the future.

Webm sample files can be downloaded here.

VideoReDo TV Suite will open the .webm sample file. Since it is a non-destructive cutter, it may be an option if you just want to cut 5 minutes of content out of 5 hours of meetings.

It's a clever screen capture browser add-on called Screencastify. It uses Google Drive on the back-end to store captured files. It has limited built-in editing capability, but I wanted to use Vegas instead. It natively saves files in Webm codec but once saved, can export to mp4. I was an early adopter and now they've mostly got all the bugs worked out so it's very reliable. I realize I can just export the mp4 version and edit that in Vegas but I was hoping to save that step and edit directly in Vegas in Webm.

@stevefoobar2

Any chance you can upload a couple of minutes to Drive or Dropbox?

I'd like to compare the GOP structure to Zoom's now that we've had to bend our brains to edit it. Also a corresponding MP4 conversion if possible.

I explained to you how you can very quickly rewrap the WebM to Mp4, but that's not your problem. the VP9 encoded file is, Vegas does not support VP9. Interestingly when I used the free version of app the original is in webm format, but for me I get AVC video and Opus audio, meaning the rewrap would work just fine for editing in Vegas only needing to re-encode the audio

This is probably a limitation of the free version. which from what I've observed is 5min screen record and 1080P. For higher resolutions it would use VP9, and this may also be the case for paid users. Paid users get the higher quality VP9 encode. Good for file size and quality, but not good for easy editing in Vegas.

Why not just use OBS Studio and pick any codec and wrapper you want?

This is a company Windows 10 laptop. Installation of applications is restricted. Hence, my "clever" use of a Chrome add-on. Chrome is installed and I'm logged into Chrome with my personal google login, so I get around their restrictions. Oddly enough, this Screencastify app is to allow me to do my job better, but such is the nature of large corporations in the U.S.

I completely understand. I worked in corporate IT for 39 years, mostly inside a data center. I was frequently amazed at how much "help" I got to do my job.

Steve, got them, thanks. Your company needs to be thankful for the competence of its employees.
