FAQ
To repair a corrupted video file online, you need to upload both the corrupted file and a working video sample to Clever Online Video Repair. The working sample must have exactly the same video settings and be recorded with the same camera in the same recording mode. Typically, this sample is the last successfully recorded file before the corrupted one.
Some devices write files to flash memory invisibly, and they appear in the file list only when recording is normally finished. If this is the case, you will need software like DiskDrill to restore the corrupted file from storage and then fix it online. This ensures that even hidden or partially saved files can be recovered and repaired with Clever Online Video Repair later.
Clever Online Video Repair does not reduce video quality because it does not re-encode the file. Instead, the tool searches for the original missing frames and restores them in their original quality. This ensures that the repaired video maintains the same quality as the original recording.
The service supports a wide range of file formats, including MP4, MOV, DAT, 3GP, 3G2, M4V, M4A, M4R, M4B, F4V, F4A, F4B, GIFV, and QT, with a maximum file size of 5GB. It can fix any corrupted video file that uses the ISOBMFF or QTFF container with the H.264 (AVC) or H.265 (HEVC) video codec. Clever Online Video Repair continually strives to expand the list of supported formats to meet our users' needs.
We specialize in repairing files that were damaged during recording on a camera or drone. If your video plays but has distortions or artifacts, it is best to re-encode the file using the free VLC media player.
Yes, files that use the MP4 container to store audio, such as M4A or F4A, can be repaired in the same way as video files. This feature ensures that not only video but also audio issues can be addressed effectively.
The most time-consuming steps involve uploading the broken file and the working sample, followed by downloading the repaired file. The actual repair process takes less than a minute. Therefore, the overall time to repair a video mainly depends on the size of the files and the quality of your internet connection.
If the video still doesn't play, try repairing the file using another working example. Often, these files are the last ones recorded before the corrupted file. You can also try recording a new file, but it's best to do this on a different memory card to avoid losing the corrupted file. Ensure you set the recording mode to match exactly: the same codec, resolution, frame rate, and bitrate.
When your repaired video still has playback issues, you may need to re-encode the video. You can try using VLC media player, which has some video repair capabilities. However, re-encoding can reduce video quality, so you might want to try a different video player, such as Elmedia Player, for better playback results.
However, if the video was recorded with Variable Frame Rate (VBR), unfortunately, no automatic video repair tool can help you. You might need to manually adjust the playback speed to sync with the audio or seek assistance from a specialist.

Yes, there is a file size limit of 5GB for both corrupted and working files on Clever Online Video Repair. You can perform multiple repairs in succession, and the service is completely free. This makes it easy to manage and repair large video files without incurring any costs.
Online video repair tools function by analyzing a working video sample recorded with the same settings as the corrupted file. The tool extracts decoding data from the sample and uses it to locate and reconstruct the video and audio streams in the damaged file. This process involves recording the identified data into a new file. Simply copying data from a good file to a bad one isn't feasible due to variations in how different sources create video files. Even with a perfect sample, repair success isn't guaranteed, but services like Clever Online Video Repair are designed to handle a wide range of issues effectively.
No video repair tool can guarantee complete restoration for every video. With thousands of unique camera models, each with different ways of writing video data, repair success can vary. However, Clever Online Video Repair is user-friendly and capable of handling large files at no cost, making it a reliable first option for attempting repairs.
Most online tools are designed to repair videos that stopped recording unexpectedly, where the frames are generally intact. However, if you recover a file from corrupted media, some frames might be missing. In such cases, re-encoding the video is necessary to make it playable again.
No, videos need to be downloaded to your device before uploading them to the repair server. This ensures the tool can access and process the video data correctly.
Video file corruption often occurs during the recording process of MP4 and its subtypes (.mov, dat, .m4v, .m4a, .m4p, .m4b, .m4r, .3gp, .3g2, .qt). When the recording is interrupted by power loss, memory card disconnection, or device freeze, the necessary decoding data is not written, making the file unplayable. These corrupted files can often be repaired using a working example file from the same camera in the same mode. For files corrupted due to hard drive failure or deletion, software like DiskDrill can help recover as much video data as possible before repair.
To prevent video file corruption, ensure your recording device is fully charged and the memory card is properly inserted. Regularly update your device's firmware to the latest version. Avoid physical damage by placing your camera in a stable position and practicing with your equipment, especially drones, to prevent accidents. Regular backups and properly stopping recordings before turning off the device or removing storage media are also essential practices.
No, batch processing is generally unavailable in online video repair services due to the extensive time required to upload and process each file individually.
When selecting an online video repair tool, consider features such as the maximum supported file size, transparent pricing policies, and the ability to detect and avoid charging for non-corrupted files. User-friendliness and platform compatibility are also important. Clever Online Video Repair offers a versatile solution with no cost for large files, making it a reliable choice.
Clever Online Video Repair offers a free service that supports a wide range of file formats, including MP4, MOV, DAT, 3GP, 3G2, M4V, M4A, M4R, F4V, F4A, F4B, GIFV, and QT. The tool detects file types, checks file integrity before repair, and uses chunked file uploads to ensure smooth processing. It works across all systems with a browser and internet access, providing a versatile and efficient solution for fixing corrupted video files.
Clever Online Video Repair is free because the developers need to test the product, fix bugs, and collect user reviews. It is a long-term project that started as a free service to build a user base and gather feedback before monetizing later.
If the online repair tool fails, it is often due to insufficient similarity between the settings of the broken file and the sample. Cameras use numerous parameters for video decoding, and even a slight difference can impede successful repair. Ensure the sample file matches the recording mode, resolution, and frame rate of the corrupted file. If issues persist, try a longer sample video. For playback issues like choppiness or seek problems, re-encoding with VLC might help, but each re-encoding slightly degrades quality. For files recorded with variable frame rate (VFR), manual synchronization of audio and video might be necessary.
There isn't a single program that can fix all broken files. Trying multiple methods is often necessary. Online video repair services may have access to specialized software not available to individual users, increasing the chances of successful repair.
There is completely free software available for video repair, but it requires using the command prompt and compiling for certain platforms, which can be challenging for the average user. Untrunc, for example, is such a free tool. However, for many users, this may not be the most convenient option.
Local programs work similarly to online services. You need a corrupted file and a working video sample to attempt a repair. However, online services might have better success rates due to access to specialized, non-redistributable software.
