I rendered 250 png images for an animation.
In QuickTime (10.5), I open these images as an Image Sequence and set the frame rate to 24 per second. This should give me a movie of around 10 seconds.

I get a 10 second movie, BUT all 250 images play within the first 4 seconds, and the remaining 6 seconds are just a still frame of my 250th image!

When I enter other frame rates, like 60 / second, I get a 4 second movie, but all the movement is in the first 40%, then only a still frame.

How can I create a movie from my 250 png images that actually plays at 24 or 25 fps?

    Hi. Welcome to GDSE. Video editing questions are off-topic here. Sorry about that. Maybe try Video Production Stack Exchange instead.

If you are using Windows, I would recommend that you use VirtualDub2 http://virtualdub2.com/. It is a very simple program.

  1. File > Open - your first frame, and if they are consecutive numbers it will be loaded as one clip.

  2. Video > Compression - And select the codec you want. If you want to export to Mp4 use x286 8 bit

  3. Video > Frame Rate > Change Frame Rate to - If you want exactly 10 seconds, use 25 FPS

  4. File > Save as - And choose your output file.

(You probably need to: Audio > No Audio)

You can even export to animated GIF. You do not have control over the generated palette or dither, but if your animation is flat enough it will compress well.

    QuickTime (10.5) says Mac through & through. QuickTime for Windows was discontinued in 2016.

  • Yeap, I would not use QT for this.
