Looping Video Without Lag?

Shotstack API
1

I have a video that is exactly 3 seconds long, I need to extend it to become 8 times longer, so I added 8 clips of the same video hoping for a perfect loop but each time the video would loop, there is a lag ruining the whole thing.

This is the result: https://shotstack-api-stage-output.s3-ap-southeast-2.amazonaws.com/xkphkx43ac/13c54878-ca58-4b3f-9e64-ad863d5766c7.mp4

Is there a way to achieve the perfect loop with shotstack?

This is my code:

        "tracks": [
            {

@dazzatron ??? Any ideas about making this work?

It looks like this file has expired or been removed:
https://s3.amazonaws.com/appforest_uf/f1679280737369x968962145952092000/infinit_zoom.mp4. Please can you share it at a permanent location so we can run some tests on it. I was able to test it earlier and noticed the frame rate was 20fps, which is not a standard frame rate which we support. That might be the issue, but if you can provide the source file I will take another look.

How is this source video created? Is it possible to repeat the last frame for about 1 second or are you not able to edit it?

Not able to edit unfortunately :frowning:

Any progress on this? @lucas.spielberg

Your video is just over 3 seconds long. 3.05 to be exact. If you start the video a frame earlier you can achieve this effect quite nicely across two tracks.
