Why a TikTok Video Will Not Open in CapCut

Last updated:

A TikTok video will not open in CapCut when the codec inside the file is one that your version of CapCut cannot read. The file ends in .mp4, but the video inside it is often HEVC, also called H.265, and not H.264.

The fastest fix is to get the video as H.264 in the first place. A TikTok downloader that picks the H.264 version gives you a file CapCut imports without an error. This article explains the cause, shows how to check a file, and lists three fixes.

Why CapCut Rejects Some MP4 Files

MP4 is a container. It is a box that holds a video stream and an audio stream, and the video stream can be encoded with different codecs. Two files can both be named video.mp4 and still be very different inside.

CapCut's own help page says that an import failure is usually a file format compatibility problem. It adds that the actual format of a file may not match its extension, and that support differs by device, operating system and CapCut version.

That is why the same file can import on one phone and fail on an older computer.

What HEVC Is and Why It Causes Trouble

HEVC is a video codec standardized in 2013. H.264 is the older codec, standardized in 2003. HEVC makes smaller files at the same picture quality, which is why phones and video platforms use it.

The cost is compatibility. Apple's export menu describes the two choices plainly: Greater Compatibility (H.264) and Smaller File Size (HEVC). On Windows, HEVC playback needs the HEVC Video Extensions from the Microsoft Store.

TikTok stores each video in more than one codec. In our own testing, a TikTok video saved in HEVC made Windows ask for the HEVC Video Extensions before it would play. The same kind of file is the one editors refuse to import.

How to Check Which Codec a Video Uses

You can check the codec before you import the file. On Windows, Microsoft describes this method:

  1. Open the video in Windows Media Player.
  2. Right-click the file in the library and select Properties.
  3. On the File tab, read the line named Video codec.

If the line says HEVC or H.265, the codec is the cause of the import error. If it says H.264 or AVC, the cause is something else, and Fix 3 below is the one to try.

Fix 1: Download the TikTok Video as H.264

The simplest fix is to download the video again in the right codec. The downloader on this site reads the versions TikTok stores for a video and chooses the H.264 one whenever TikTok offers it.

Paste the link of the video, select Get video, then select Download HD video. The file is an H.264 MP4 without the watermark, and you do not need a converter.

This works for public videos. A video from a private account cannot be read by any link-based tool.

Fix 2: Convert the File to H.264

If you cannot download the video again, convert the file you have. CapCut's help page recommends a trusted conversion tool for a file it cannot import.

  • On a Mac: open the video in QuickTime Player, choose File, then Export As, and select Greater Compatibility (H.264).
  • On Windows or Mac: in the free program HandBrake, choose the MP4 container and set the video codec to H.264, then start the encode.

Converting re-encodes the video, so it takes time and can soften the picture slightly. That is the reason Fix 1 is better when the video is still online.

Fix 3: Clear the CapCut Cache and Check Permissions

Some import problems have nothing to do with the codec. CapCut's help page lists three causes for a black screen during import: a temporary glitch, cache issues and permission settings.

Close CapCut and open it again. Clear the cache in CapCut's settings. On a phone, check that CapCut has permission to read your photos and videos.

Does Renaming the File to .mp4 Help?

No. CapCut's help page states that renaming a file does not change its actual format. The codec stays the same, so the import fails again.

Frequently Asked Questions

Does CapCut support HEVC?

It depends on the device and the CapCut version. CapCut does not publish a simple list, and its help page says support differs by device, operating system and version. H.264 is the safe choice.

Why does Windows ask for the HEVC Video Extensions?

Windows needs that extension from the Microsoft Store to play HEVC video. An H.264 file plays without it.

Will the video lose quality if I convert it?

A little. Converting encodes the video a second time. Downloading the H.264 version directly avoids that step.

Why does my iPhone record HEVC video?

Apple devices from the iPhone 7 on, with iOS 11 or later, can record in HEVC. The setting is in Settings, Camera, Formats, where Most Compatible switches recording back to H.264.

How do I get the TikTok video onto my phone first?

The steps for getting a TikTok to camera roll cover both iPhone and Android.
