Issue with Loading Files in Sony Vegas (No video/Audio Issue)

[Francois Pénzes]

Hi Susie

First off, uninstall K-lite. Make sure everything is gone from K-Lite, including in the registry. It creates way more problems than it solves.

Can you post https://mediaarea.net/en/MediaInfo of your original file(s) ?

Cheers !

Thank you for the response. As far as I’m aware, I have removed all of the K-Lite Codec files using Revo Uninstaller and rebooted but Sony Vegas is still broken. I don’t have experience with MediaArea so correct me if I did it incorrectly:

Why didn’t you just uninstall K-Lite using their uninstaller? 3rd party uninstaller are guessing at best what to uninstall and should only be used if the regular uninstaller has failed to remove the software. K-Lite should NEVER be installed on a video editing computer. I guess you know that now. (most people learn the hard way so don’t feel bad).

Try these steps to recover until one of them works:

1. Reinstall Sony Vegas. That should hopefully re-establish the codecs that K-Lite over-wrote.
2. If you regularly backup your computer, (and why wouldn’t you?) try restoring from a recent backup. If you don’t back up your computer, now would be a good time to think about making that a habit. 😉
3. If you have no backup, see if you have a Windows Restore Point from before K-Lite got installed and restore your computer to that point. That might finally get rid of it.

Hopefully one of those will work and you won’t have to resort to re-installing Windows but some people have had to do that to get rid of K-Lite. (did I mention to never install K-Lite?) lol

Good Luck (you’re gonna need it)

Okay, so I tried to reinstall (and update) Sony Vegas and that did not work. I also restored windows to a few days before the K-Lite Codecs were installed, and that did not help. Eventually Sony Vegas could not read the files, and we resorted to the Codec Tweaker Tool (https://www.thewindowsclub.com/codec-tweak-tool) which detected and removed registry keys/broken codec files. The old problem with the audio persisted. I’m at a loss at what to do, and I’d really rather not re-install windows. If nobody has any ideas I may just give up on Sony Vegas and move on. If that is the case then thank you for the feedback and help thus far, it has been much appreciated.

Did you try Francois’ idea? He pointed you to a program called MediaInfo. You can open your video file with MediaInfo and it will tell you what codec it uses. Then you can try and get that codec fixed on your computer.

It is disturbing how little people here know about codecs and how Vegas works. This leads to a lot of bad advice.

Sony Vegas does NOT use DirectShow filters. This is the type of ‘codec’ that K-Lite and other codec packs use for playback. This means that K-Lite simply does not have any effect at all on Vegas. So it does NOT cause problems, but it also does not expand the import capabilities of Vegas.

Sony Vegas uses its own private plugins for importing MP4 files. These plugins are not registered globally (like normal codecs) and you do not need to worry about other programs replacing or removing them.

If you look at the file properties in Vegas, it should show which plugin it uses. This website describes how you can change which plugin it uses for MP4:
https://www.vegascreativesoftware.info/us/forum/faq-why-won-t-vegas-open-my-file-correctly-codecs-converters-etc–104572/

Sony Vegas uses/needs QuickTime for importing file formats such as MOV and 3GP. It might also help for certain MP4 files. So make sure QuickTime is properly installed.

The only external codecs that Vegas uses are ACM/VFW codecs, and that is only for AVI files.

Not according to the K-Lite web site: https://www.codecguide.com/about_kl.htm

The K-Lite Codec Pack is a collection of DirectShow filters, VFW/ACM codecs, and tools.

I’ve seen K-Lite mess up many installations of Vegas Pro and Movie Studio over the years and those that it has happened to will agree. It definitely has an effect.

[Andrew Blake] “Sony Vegas uses its own private plugins for importing MP4 files. These plugins are not registered globally (like normal codecs) and you do not need to worry about other programs replacing or removing them.”

This is not globally true and changed with different versions of Vegas Pro over the years so while some newer versions may use their own private plug-ins, the majority of older versions did not. I’ve been using Vegas since Vegas Video 3.0 and I’ve seen it all. Not just video codecs but audio codecs get messed up too.

Allow me to restate the claim made in the original post:

“Last night a friend installed the K-Lite Codec Pack and this issue started immediately afterwards.”

So the video worked one minute, they install K-Lite and now it doesn’t work. How do you explain that?

[John Rofrano]“The K-Lite Codec Pack is a collection of DirectShow filters, VFW/ACM codecs, and tools.”
Only the largest version contains VFW/ACM codecs, and those are all harmless. Furthermore, that type of codec is only used for AVI files.

[John Rofrano] “I’ve seen K-Lite mess up many installations of Vegas Pro and Movie Studio over the years and those that it has happened to will agree. It definitely has an effect.”
I only see topics like this one where it gets the blame without any factual evidence. I know its developers are eager to fix problems, or prove that a fault lies elsewhere. But that is impossible to do based on just anecdotes.

[John Rofrano] “This is not globally true and changed with different versions of Vegas Pro over the years so while some newer versions may use their own private plug-ins, the majority of older versions did not. I’ve been using Vegas since Vegas Video 3.0 and I’ve seen it all. Not just video codecs but audio codecs get messed up too.”
I am assuming that the topic starter is using a somewhat recent version. You will have to agree that those use internal plugins for MP4.

[John Rofrano] “So the video worked one minute, they install K-Lite and now it doesn’t work. How do you explain that?”
I think that this simply is a wrong observation from the user. Or at least the wrong conclusion. Other things might have been installed as well. It might be a different file. Or the cause might be totally unrelated. The same problem also occurred with a restore point from a time before K-Lite was even installed.

I know for a fact that K-Lite does not change/remove/touch anything related to Vegas. You can easily verify with SystemExplorer, which allows you to create (and compare) snapshots of the Registry and filesystem. This will also show you that it properly uninstalls and makes no permanent system changes. We have also concluded already that recent Vegas does not use external components for importing MP4. So how can K-Lite break anything? You blame it because that is the easiest way to say that you don’t actually know what is wrong?

[Andrew Blake] ” You blame it because that is the easiest way to say that you don’t actually know what is wrong?”

I blame it because I have seen it break things in the past. The K-Lite codec pack has had a history of causing problems for Sony Vegas and Movie Studio. It’s not that K-Lite itself is “trying” to break things, it’s that there can only be one “default” codec for a particular video type or 4CC so when K-Lite registers it’s codecs over the ones that Sony installed, Vegas doesn’t always work correctly. Then you uninstall K-Lite, and Vegas starts working again. You can call it coincidence… I call it “cause and effect”. I have seen it too many times and this is exactly what the original poster was describing. Very prevalent in the days of AVI files. I realize that recent versions of Vegas now ship it’s own MPEG4 codecs, so maybe not so much now with MPEG4.

If you are saying that newer versions of K-Lite do not affect Vegas negatively then I’ll take your word for it. I don’t use Vegas or Windows or anymore so I’ll refrain from commenting on the affects of K-Lite but in the past, it would mess Vegas and Movie Studio up. You could argue that it is Vegas’ fault for not working with alternate codecs, but it would definitely mess things up none the less.

It might be the audio stream causing the problem.

I used to record MP4s using OpenBroadcastSoftware once and I also had problems importing them to Vegas.
The issue in my experience was audio stream being in MP3, not AAC.
Vegas did not open MP4 files with MP3 (mp1 layer3) audio stream.
I switched to AAC (OBS/Settings/Encoding/Audio Encoding) and it all worked fine.

BTW, I have K-LITE installed in Full mode.
