First, 50 and 25 are compatible in the same project.

Second, are you sure what undersampling does and why you need it?

For most of us, it gets used once in a blue moon, not as a general editing tool.

Third, you would change your clip properties in Project Media, not on a multicam timeline.

Are you sure you need to do that? Vegas will conform all your clips to the project frame rate unless told other wise ( ie disable resample).

yes. Everyone needs that because if you don't change framerate in clip which have 50fps and u edit 50fps & 25fps so after rendering into 25fps ur clip with 50fps is more smoother. If you change it in properties it looks like it was shoot in 25fps

I've never experienced that result, sorry.

You can drop frames or blend frames using the Resample properties. If you can explain what Undersampling does that Resampling Off doesnt do in a 25p project, I'm open for a teachable moment. Oh the script will automate that too.

I've never experienced that result, sorry.

ohhh... you are lucky :(

Uh, I'm not sure I've ever had to experience that result. But best of luck finding your own solutions.

@Komaryt

Makes no sense to me to do this the way you are suggesting. Can you post a sample to prove your point?

There is some sample. The most difference has been seen on party, but I don't want to upload some party shots because I don't want to reveal faces and when I blur you won't see any difference ;)
You will mostly see difference at 1:13 when I was going with glide.
Clips with 50fps are different because they are from C100 Mark II but the difference is the same like this.

Please do not comment colours on footage because it was shooting in c-log so I will grade it after ;)

project settings

render settings

Ok, thanks for the example, it now makes sense: you are matching the footage and prefer to give the 50 fps footage more "cinemalike" cadence by under sampling.

So, just change one event, ctrl-c, shift select the others, then paste-event-attributes will do them all. I am using vegas 14, but is similar in v15.. I think... my trial expired :(

The OP is putting 50p in a 25p project if I understand.

One last time-- will some please explain what Media Undersampling accomplishes that Event Resample Off does not accomplish??

Inquiring minds want to know...

Yep. Because I dont like how 50p looks. I AM using it only for slowmo but unfornatelly c100 records in 50p only and I record with my 7d in 25p so I need to mach it somehow ;)

But when I edit movie in multicamera I need to change framerate on every cut from c100 so it takes me a lot of time and I am looking for some tips about how can I change it once for every cut.

Vegasaur helps but a little because I need to click on every cut.

Oh forget it. Best of luck.

@Musicvid

Would need to see a render of each method to see if there is a difference. Not sure.

@Komaryt

Just click the first event and shift click the last event to select them all; then paste-attributes. If that doesn't work for you then press D a couple of times to get the selection tool to select all the events (cuts). No problem, right?

@Kinvermark

I predict there will be no difference whatsoever, except possibly to save one or more extra steps. Sorry I'm not at my editing computer this week.

The OP originally asked for ways to save extra steps, did he not???

@Komaryt

1. Don't change the undersample rate for any media. Leave it all at 1.000.

2. Make your Project Properties like this:

3. Select all the video streams on your timeline (not the whole events including audio). Right click > Switches > Use Project Resample Mode. I think this is the default, so probably doesn't need changing.

The result should be exactly the same as undersampling to 0.5 with "Smart resample". At least it is the same when I test it with 59.95p > 29.97p footage.

If you're actually shooting an interlaced format on your C100 then it's a different story.

More info on resampling here.

Thanks for confirming I was temporarily, if partially sane yesterday, Nick!

Guys I figure it out how to make is simply.
I don't need to change framerate in properties of any clip (even after I edit in multicamera so I must change every cut) I found yesterday plugin in vegas FRAME RATE. I can add it as MEDIA FX, change it into 25fps and I have clip with 25fps (when it was before 50fps) !!

I am so happy!!

Do I miss something? When I put 50fps footage in a 25fps project, I just make sure (in V14 andV15) that in the project settings the resample mode is disabled. Vegas will automatically render the 50fps to 25fps by leaving every second frame out (that's the same what media FX framerate does). If resample mode stays active, Vegas will combine two 50fps frames into one 25fps frame, will will result in a ghosty and blurry image.

In my case it doesn't work look at it

Why do you think it didn't work?

Why do you think it didn't work?

Read all the topic. I gave there screenshots and example.

I see in your comments that you did not react on Nick's suggestion to change your projectsettings for the resample mode. In your reaction on the comment of 3POINT you say his (same) advice did't work. Did you try it and, as far all of us here think, its the only and the best solution for your suggested problem and you aske for a solution to improve the smooth rendering.
I hope you got it that a solution for this is not to change the framerate of the source.
Resampling yess or no, makes the difference if the renderframerate is different from some source framerates.
