No bug here, worked as intended.
When I want to replace a file in VPro 17 I rightclick that file in Project Media and give the place on my hardware to replace it by an equal file with the same name.

For making proxies in VPro 17 the program has its own system that swaps by change of the preview. Read the manual.

@j-v It seems to be intermittent. I tried it again last night and it worked but without showing the dialog indicating which files were swapped

And it just happened again. No error messages, just doesn't swap the videos.

Changing the folder names (the original and proxy folders are at the same level) lets me work around this for now.

I'll have to see about filing a Magix support request.

@michael-harrison Are you swapping files where some are on an external drive? I'm having a terrible time with that. When I swap files that are on the local drive, there's no problem.

@Robert Johnston Hmmm. Yes, I *am* using an external drive. I'll give the internal drive a shot for a while and see what happens

@Robert Johnston Nope. Just flat out doesn't work. No error message. Just nothing.

@michael-harrison Sorry that didn't work. Maybe Vegas 15 isn't compatible with 17 in that regard. Did you try a new project in Vegas 17 and swap files on just the local drive.

Have you opened your Vegas 15 project in 17, and then saved the project in 17? Or have you only opened the 15 project in 17? Use a different filename when you save the 15 project in 17. Then close and then open the 17 project you just saved. Then try swapping on local drive.

@Robert Johnston I've had this happen with a brand new project, though I did start out by opening a 15 project in 17 and saving it back out as a 17 file. The current failure was with a fresh 17 project that I'd moved the media over to a local drive. I'll try renaming the usb media so it has to start local, which is something I didn't think of last night

One thing I've noticed that may be unrelated, I'm not sure, is that apparently the peak file format has changed in some way. I'm opening the same media files in 15 & 17 as I evaluate upgrading and every once in a random while, one or the other will decide that it has to create new peak files for all the media.

I've got a magix ticket open and will keep this thread updated on progress with that.

@Robert Johnston so far Magix hasn't been of any help. Their response was to ask for an msinfo log and then tell me to do a clean install of my intel and nvidia drivers. While that helped with VP randomly crashing at other times, they've gone silent on the replacement issue.

I'm using the Happy Otter scripts to handle switching between proxy and full res for now

@michael-harrison After the last time, I had Swap working very well. Then I ran into a problem when I tried to swap files where one file out of 20 didn't have a partner. After that, I couldn't get Swap to work in that project again, even when I added the matching file to the other folder. I think picking the wrong folder can cause a problem, and it could even be the cause of the problem I had and not the missing partner. Or could it be that I sneezed.

Whichever the cause, I have to be very careful that I pick the correct folders and that there's matched files, otherwise Swap could become bricked in that project.

I couldn't find Swap in Help. Did you?

@Robert Johnston No, I haven't seen anything in the help about Swap

Having this problem the last few days in two different projects.

I have a folder called DJI_4K. That has 6 clips in it. Inside that folder is a subfolder called 720p with the same-named clips.
DJI_4K
  DJI_4K\720p

I've dropped the 720p clips into my timeline for editing. Now in my finishing work, I'm selecting the media in the project media, right-click, Swap Video Files -- I select the DJI_4K folder... nothing happens, no error, no swapping. I've done this in the past without a problem. I've confirmed the filenames match 100%.

For shits and giggle I created a new subfolder under DJI_4K called "4K" and moved the 4K media from that parent folder into the subfolder...

DJI_4K
  4K
  720p

Made no difference. When I chose the 4K as the new folder and press OK, nothing happens.

External drive (J: is mapping).

This is non-critical as there are work-arounds (manually replacing, using Vegasaur feature to do the same thing, etc), but Definitely a bug in Vegas.

I have the same problem, when trying to swap files - nothing happens.

No error, no dialog window, nothing.

It was working in previous versions for sure - I used it a lot of times before.

Last version of Vegas 18 (build 373)

yes, this is so frustrating. just doesnt do anything and no warning. now i'm stuck with rendered proxies..

For speed reasons I decided to create my own proxies for my 4k video and use the media chooser option "swap video files" to go back and forth.

I'm trying out VP 17 (possibly upgrading from 15) and I've discovered that this apparently no longer works? At least with an existing VP 15 project it doesn't.

Even though the file names are the same between the two folders, it refuses to swap videos and doesn't give me any kind of error.
 

known bug?

@michael-harrison not known bug but it is for sure a bug in Vegas 18 because I had the exact same problem few days ago. Here is the post:

https://www.vegascreativesoftware.info/us/forum/fastest-way-to-swap-proxy-with-raw-version--125782/

Vegas V18 is very unpredictable with some tools where sometime it work and sometimes it stop working for no reason. I had to move my project and files to my laptop and do swap command there, save the project and return to my desktop to finish the editing.

V18 still has many other bugs that are not recognized by magix as bugs and my guess many of them are inherited from previous versions

@oskari-m Depending on the size of your project, if you have a lot of media this could be painful, try using the "replace.." menu option when you right-click on a file in the media list. You can manually swap files that way

doesn't work any better, just doesn't swap any file. it don't do anything, no error, no dialog. just pure "silence"
