Post the.mov file details.

https://www.vegascreativesoftware.info/us/forum/faq-how-to-post-mediainfo-and-vegas-pro-file-properties--104561/

To clarify, these are 2 separate issues. One is .mov files on 20 and 21, the other is that all files crash 21 which is the bigger issue.
But since you asked, here are the .mov deets. Had to do this in Vegas 14 since, yknow, 21 isn't working

That isn't what was asked for in the link. Download mediainfo, and post the report it generates when you run it on the file by right clicking on the file and selecting "mediainfo".

My bad, I skimmed it and thought it was an alternative option.
To clarify a bit further, the simple act of turning on the ability to use mov files breaks 20 and 21. I don't even get to add the file. Additionally, this is secondary to being straightup unable to use any video files in 21, even if I never activate .mov file compatibility

this is just an mpeg 4 file in a qt wrapper, which VEGAS is fully capable of running without the need of quicktime.

I'd reset VEGAS to get it working normally again. Leave QT off.

It seems like something is corrupt with the quicktime installation that is crashing VEGAS...

You can always rewrap the mpeg 4 video into a mp4 container... try this. Install VLC media player, then...

VLC allows you to switch containers.

Select Media->Convert/Save, select files, Convert->Save, click "Create New Profile" icon, change container, check "keep original video and audio tracks". It should re-save the video as an mp4 file without recompressing it.

Wouldn't that make it so that there's no transparency? I need the video to be transparent

MPEG-4 video doesn't support transparency anyway, and that's mpeg-4 in that .mov container.

Actually, my bad, I see it's encoded as RLE... What is the source of this video?

Me. I received a .mov file that vegas 14 refused to make transparent so I had to take every frame and rebuild it. It works perfectly in 14. I do want to re-emphasize that the issue isn't the video. I get problems even before adding this video into 21

You should be able to convert your video to a png sequence with alpha channel retained by first installing FFMPEG Here is a guide for installing FFMPEG. This is a great tool to have for video production, it can do all kinds of useful stuff.

https://phoenixnap.com/kb/ffmpeg-windows

Then open notepad, and type this in:

ffmpeg -i INSERT YOUR VIDEOS FILE NAME HERE.mov -r 24/1 output%03d.png

Make sure you change the 'insert your videos file name here' to match the name of your video file.

And save it into the same folder your video file is located in with a .bat extension, so like "convert.bat". Make sure afterwards windows doesn't add a ".txt" extension afterwards. If so, just rename it to delete the .txt at the end.

Now double clicking that file should convert the frames of your video to .png files, which you can then import into vegas by clicking on the first file in the png sequence, and selecting "open sequence" from the open dialog. You should get one video imported into vegas file that has the alpha channel preserved.

There's an alternate way to use ffmpeg other than using the .bat file, if that gives you trouble. After following the installation guide above to install ffmpeg on your system, open windows command prompt by searching for "cmd" or command prompt from the windows search bar. When command prompt opens, type "CD" and then whatever directory your video file is stored in, so let's assume I have the video file on my D:/ drive, in a folder called videos, and a sub-folder called my project. You'd type "cd d:/videos/my project". Upon doing so, you should see the command line update to "D:/videos/my project". Then type in that command I posted above,

ffmpeg -i INSERT YOUR VIDEOS FILE NAME HERE.mov -r 24/1 output%03d.png

and don't forget to edit that file name to whatever the name of your .mov file is. Hit enter, and ffmpeg will work its magic, converting the .mov file to a sequence of .png files that all have an alpha channel, and all of which can be imported as a png sequence into VEGAS using the method described in the post above.

Hope this helps!

It's advisable to avoid using the deprecated quicktime plugin when possible, as it poses a security threat to windows, because apple stopped supporting quicktime for windows and therefore no longer patches any security vulnerabilities it could pose. This gets around that. VEGAS natively supports most types of .mov files, but there's still a few that it doesn't, so we have to use tricks like this to get around it.

Thanks! This should definitely solve one of my problems
I do still have the issue with 21 not working at all. I'm sorry I keep repeating this, but I don't want people to misunderstand and think the vegas 21 issue is resolved

Are your video drivers up to date? The white screen crash suggest that they may not be. The driver update is in your Help menu.

General troubleshooting help begins here:

The nag screen you got is not a showstopper. It means you are importing media that is less than ideal for editing.

For the initial post, if media has long GOPs or otherwise will work poorly in VEGAS it shows that warning. Take the warning seriously as it can help you avoid stability issues. I'd run the media through ShutterEncoder or another program to constant framerates h264 or ProRes 422 and re-attempt the import.

If you'd like to try known-good projects with known-good media there are two in my signature you are welcome to test with 21. If they fail to open something is very wrong.

Finally if we can't resolve your issue you can file a support request- this is only a user forum.

Yup, drivers are all up to date. Using the "unoptimized" file makes the preview look like garbage, which wasn't an issue in 20. I ended up converting it and it is better now

I was under the impression that 21 broke when you enabled quicktime... if so, you should be able to reset vegas to factory settings (IIRC hold ctrl+shift when launching it) and that should fix the issue... Let me know if it's something beyond that.

As for converting the video to another format like it asks you to, use handbrake. It's a free app that will convert the file for you.

oh 21 definitely breaks when quicktime is enabled :P
Despite doing the factory settings trick numerous times, it seems the most recent one has resolved all my problems (I'm not even gonna touch quicktime anymore)
Handbrake is amazing and I use it all the time, was just hoping to avoid needing to convert all my files going forward

Yeah, hoping to avoid needing to do that in the future :/

Well I have checked enable the quicktime option in depreciated features and added MOV files to V21 trial and all is fine no issues at all. (maybe it is the MOV contents in your file which is the issue). Also V21 plays back MOV files without quicktime enabled.

Also V21 plays back MOV files without quicktime enabled.

"Well that just can't be right at all"
*adds the file in question*
"yeah, it doesn't even add the video track, just the audio"
*adds a different .mov file on a hunch*
"hey wait a second... this one opens normally... What If I tried the original file that didn't allow transparency in vegas 14..."
*it works perfectly*

I have no idea what the difference is between 14 and 20/21 in terms of how they process .mov files, but there clearly is some difference. the original file on 14 would have some frames where the background was a holdover from earlier frames (as seen in image 1) and for the few frames where the background IS transparent, it doesn't allow transparency. This same file works PERFECTLY on 21. I'm losing my mind over this fact.
