I have a need to create multiple snapshots with unique file names.

Currently I am using a shortcut that creates the unique name based on file date and time.

I used "C:\Users\myuser\pictures\snapshot {0:yyyy-MM-dd H-mm-ss.f}.png" as the value in the shortcut.

This works very well, creating file names like "snapshot 2018-12-26 21-36-47.1.png"
I am combining the snapshots into a time-lapse movie, so I need unique, sortable file names.

My question is whether there is a value that will increment a file name in much the same way that "new file every" does in recording capture.

I would like filenames to automatically increment as they are added... something like "snapshot00001.png", "snapshot00002.png"

Your thoughts are appreciated.

I would write a small script that renames all the files in a folder according to the creation time.

if all you want is it to be sortable the date you are using is already chronological not ?

and one could even simplify it say with just using the time , one can even omit the dashes like /snapshots {0: hhmmss tt}.png

else will need MartLeib's suggestion or use some (existing) mass file renamer

I use a very nice image management tool called ThumbsPlus. One of its many features is that it will auto-rename a sequence of pics, appending numbers after a prefix.

I appreciate the comments, but does someone know how to do what I asked?
The current naming does not pose a sorting issue for me... but I would prefer a simple sequence number without post processing of the files.
This way it could be easily turned into an image sequence when the capture is complete.

@ AlanZ

How are you creating your Image Sequences now?
The vMix Image Sequence Input does this automatically with sequential images in a folder, is it that the timestamp is not recognized as a sequence?

I was under the impression that vmix and some other programs expect sequentially named files when defining an image sequence. I don’t think they look at the file date/time to determine order.

I am creating the files by taking snapshots in vMix, as stated in my original post.

Pinging the group again with the original question: Is there a shortcut value for a snapshot that will increment a file name in much the same way that "new file every" does in recording capture?

Alan,
AFAIK it is not possible to add a sequence number field to file name templates in Snapshots, Recorder, etc.
I thought I made a Feature Request for that years ago, but can't find it.

If you code Python... or find a nice coder... you can probably get a script to capture your sequences as a timed delay if you do time-lapse.. and name your snapshots as you desire directly in Python...


I got SnapshotInput working as a weblink... cool!

For vMix 22!

Stored in C:\Users\YourUser\Documents\vMixStorage

http://localhost:8088/API/?Function=SnapshotInput&Input=1&Value=mysnapshot%20{0:yyyy-MM-dd%20H-mm-ss.f}.jpg

And this little Python 2.7 script ....

Code:
import socket
import time

s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

s.connect(("localhost",8088))

sleeper = 1 #Time to wait in seconds between snapshots!

SnapshotInput = "GET /API/?Function=SnapshotInput&Input=1&Value=mysnapshot%20{0:yyyy-MM-dd%20H-mm-ss.f}.jpg HTTP/1.0\n\n"


def your_function1():
		s.send(SnapshotInput)
		#s.close()

		
while True:
    your_function1()
    time.sleep(sleeper)

As I previously mentioned, I am not having any difficulty converting the capture images into a time-lapse file. I “simply” was looking for an alternative to the date/time naming convention (at create time, not via post processing)

For anyone interested, here is my possibly unique use of vMix with an X-key controller to capture 3D print progress

Just ran into this issue today.

I wanted to use sequential names like many other image programs offer.

So Image#####.png would give me a sequence starting Image00000.png Image00001.png Image00002.png.

But I was only able to come up with a date time stamped version.

What is that leading 0 in the name?

Quote:
0:yyyy-MM-dd H-mm-ss.f


I was thinking the 0 was for numbering except mine keep coming out with the same number to start.
Since this is a test right now I wonder if later today it will change or if tomorrow it will be a different number.

Honestly I have no idea I just copied from the example to make sure I didn't mess it up.
