Regularity of pictures. Trying to show pictures to match beat/rhythm of a song but they display themselves irregularly

Issue is pretty much the title. Trying to get the photos to show up on the beat of the song and have set durations at 1 and 0.5 seconds but they don't show at the same rate and are offbeat.

are you referring to display in Camtasia editor canvas, or in produced video?

can you do a short screencast, host on screencast.com, that shows the issue your are trying to resolve

some details about the photo dimensions, your project dimensions would help; maybe a screenshot of the project at ctl-shift-7 max zoomed out

I work extensively with projects made entirely from photos, and do not experience what you're describing?

Here's a recording on Screencast. You'll note how some images pop up irregularly; some slightly quicker and some slower

thanks for the recording; loaded it in Camtasia 2018; now see what you're referring to

looks like your images have different dimensions, but durations on timeline look the same?

Yeah the durations are all set the same but watch the video and see how they pop up as the video plays. Do their dimensions affect that?

As I described below, the music is out of time with images because the beat is not timed to seconds on a clock.
The images are all the same duration.
Heres proof of that. Videos are split into frames per second whereas music follows no such rule book.
With the timeline indicator placed between 2 images. As per your recording, the frame rate at the split/timeline fps rate. Matches exactly from one end of a large string of images to the other.
Heres a 1 second image comparison.

And your 0.5 second images comparison.


Timing the music using beats per second.Isn't  going to work. Please read post below for clarity.

I understand it won't match the rhythm but look how quickly it cycles from picture 4 to picture 5. That is less than a second. Then picture 11 seems to have a longer duration than 1 second. The durations don't seem to be consistent

You can set image duration in preferences. That will add all your images to the timeline at the same duration automatically. But you can only set the duration in tenths of a second.


However, most songs don't have a beat that syncs to time in terms of exact timing/beats per split second. Unless someone used a synthesizer to created an artificial/computer generated beat. I'm not sure a synthesizer  keeps a perfect beat either.

If a duration setting were all that's required, to sync Images,callouts, titles etc to music. That would be great and everyone would be doing it. Unfortunately, that's not the case.
You need a program or plugin that detects beats and places markers or aids you in some way.
Like beat editor for After Effects. https://aescripts.com/beatedit-for-after-effects/

my last above post got chopped off; this site giving me grief today; again ...

looks like your images have different dimensions, but durations on timeline look the same?

the images seem to have different dimensions?

what you are seeing might be the editor struggling to scale the photos in real time

does the issue happen in a produced project?

if you use same dimension photos, does it still happen?

looks like you're making photo slide show music videos

I've made many thousands of them myself over the past 12 years

in many cases, I've reasonably matched the music cadence to the photos; typically the photos all have same duration on timeline, and all are pre-processed to have the same dimensions before importing into Camtasia

I use Adobe Lightroom to manage my photos, and to export photos for use in Camtasia projects

I take photos with a digital SLR Cannon; saved as JPGs at native dimensions [4752x3168]

these are exported at 1620x1080 [or 1080x1620 if portrait orientation] , which gives me optimum fidelity when produced at 1080p HD

the pre-processing of the photos really helps when in the editor

I've made many such productions with up to 500 photos in a video

I added several images of different resolutions to the timeline in 1019.0.3 at 1fps and then at 0.5 fps.
My results are consistent and perfectly timed.
A screen recording like a .trec is not 100% accurate in terms of fps and what's actually occurring on the screen in fps. And I'm going by your recording.
If you can demonstrate to tech support inconsistent duration's being generated, you should contact them.
