Why won’t TikTok let me trim my video? Possible reasons include a video that’s too short, a trimming tool that's unavailable, or accumulated app cache issues. This post explores these reasons clearly and offers solutions. It also shows how to trim videos on TikTok and shorten a video for TikTok on PC using MiniTool MovieMaker, a Windows video editor.
Why Won’t TikTok Let Me Trim My Video
Quick answer:
- The video is shorter than 15 seconds.
- The trim tool is not available in the current TikTok app.
- Cache issues.
In this section, we will simply analyze the possible reasons why TikTok prevents you from trimming your video. In addition, we will provide some helpful suggestions to solve this problem.
1. The Length of Your Video Is Too Short
You should know that TikTok has its own limits and rules for trimming videos. The minimum video length is limited to 15 seconds on TikTok. Therefore, TikTok won’t allow you to trim a video that is less than 15 seconds long.
Fix: Try to add more video clips to your existing video or slow down your video to make it longer. Additionally, you should note that if your video is too long, it may be split into multiple parts to get more exposure.
2. Your TikTok App Has Been Updated
Why can’t I adjust my clips on TikTok through the option of Adjust Clips? Recently, some people have reported that they couldn’t find the Adjust Clips button on TikTok, which was previously located at the top right corner of their screen.
Actually, it’s probably because your TikTok app has been updated. The latest version of TikTok has replaced the Adjust Clips button with the Studio option. So, you can’t trim your videos through the Adjust Clips button.
Fix: You can continue to use the Adjust Clips button by downgrading your TikTok to the old version. However, it’s better to familiarize yourself with the trim tool on the latest version.
Besides, the second part of this article will guide you on how to find the trim tool on TikTok and how to adjust clips on TikTok’s latest version by using the trim tool.
3. Too Many Cache Files Make Your TikTok React Slowly
Why won’t TikTok let me trim my video? In addition to the two reasons mentioned above, lots of cache files accumulated on TikTok may prevent you from trimming your videos.
That’s because those files may result in temporary glitches and app bugs in TikTok. Plus, poor network signal may also lead to abnormal operation of the trim tool on TikTok.
Fix: When the trim tool on TikTok doesn’t work, you can try to clear the app cache or quit TikTok and restart it.
