How to make frame duration less than one frame in video timeline mode?

[desktop.surgeon]

Unable to make the duration slider go under one frame, haven't found out another way. Really want to take a section of my animation and speed it up (make all the frames .75-.5 of a frame) to make it smoother, without affecting the frame rate of the whole timeline etc.

thanks!!

I have always found video editing confusing. While researching in attempts to help you, I found that duration is the first-to-last frame length, the length of the video clip.  Frame Rate is dependent on the type of output -- NTSC, 29.93 fps.

"When you create a new document, the default timeline duration is 10 seconds. The frame rate depends on the chosen document preset. For non-video presets (like International Paper), the default rate is 30 fps. For video presets, the rate is 25 fps for PAL and 29.97 for NTSC."

Near the bottom of that webpage are the instructions --

1. From the Animation panel menu, choose Document Settings.

2. Enter or choose values for Duration and Frame Rate.

From the Timeline panel, try setting Timeline Frame Rate to Custom. Ps let me set it to 1,000 fps!

I think you'll need to remove frames.

Unless you have After Effects.  I am pretty sure that could do it.

Or maybe Animate or other third party app.

I don't think Photoshop is going to work for you though, (but who knows? )

Aside friom the advice you already got could you please elaborate and post screenshots taken at View > 100% with the pertinent Panels (Toolbar, Layers, Timeline, Options Bar, …) visible? 

Because I am not completely sure I understand what you want to achieve.

Hi @desktop.surgeon,

In Video Timeline mode (like in Photoshop), frame durations are tied to the timeline's frame rate—so you can't set a duration shorter than one frame (e.g., 0.5 frame) directly.

To achieve smoother or faster animation:

• Increase the frame rate of your timeline (e.g., from 24fps to 48fps).

• Then re-time your animation using that higher frame rate to give the illusion of sub-frame timing.

• Alternatively, use a video editing tool like After Effects or Premiere Pro, which offers time remapping for more precise control.
  
  

Hope that helps! Let me know if you want help setting up the higher frame rate.

Hey @desktop.surgeon, 

I wanted to check in and see if the suggestions were helpful or if you needed additional assistance. If any specific post was particularly helpful, please be sure to mark it as correct. Thank you!

I think I ended up importing the animated sequence into premiere and
changing the duration there. The first couple answers didn't really speak
to me and then I forget to check back after! Whoops.
Thanks for checking in.

I'm sorry @desktop.surgeon . We didn't do a stand out job for you earlier.  

OK, this is an empty video layer/clip five seconds long.

Set the Play Head to the start of the section you want to change, and hit the scissor icon.

Move to the end and cut again.

Right click the section you want to change and adjust its Duration

AFAIK, Photoshop does not have a Ripple Delete feature to trim the empty part of the timline, so you'll need to select everything after the shortened clip and reposition manually.

BTW, if you have Premier Pro, I'm wondering if you have a full CC subscription, because Photoshop likes to fight you with video animation.  It's fine with frame by frame drawn or tweened animation, but I tried for ages to rotate multiple video layers with unlinked masks to do a kaleidoscope effect, and by heck it was a pain!  After Effects is orders of magnitude more capable, and the way to go in my experience to date. 

I have made frame animations for a good many years, but recently changed to video for the smoother motion (which is why I gave you a pants answer earlier) and while its fun to be on a new learning curve, that fun can fade away when Photoshop refuses to play nicely.
