FAQ

To repair a corrupted video file online, you need to upload it to Clever Online Video Repair. The analysis and repair process will start automatically as soon as the upload is complete. If the system cannot detect the video or audio parameters, you’ll need to upload a working sample file recorded with the same device or software using identical settings. Typically, such file is the last successfully recorded before the corrupted one.

Registration is optional, but without it, you’ll be limited to three broken files and only 24 hours of storage. We recommend registering to get more space and time for your repairs.
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.

However, if the original file plays poorly or an error occurs when importing it into a video editor, we recommend re-encoding it in high quality.
We specialize in repairing video files damaged during recording on video cameras, action cameras, smartphones, or drones. Clever Video Repair also repairs screen recordings and live streams that were unexpectedly interrupted.

The service fully supports a wide range of file formats, including MP4, MOV, Canon DAT, 3GP, 3GPP, 3G2, 3GPP2, 3GA, 3GPA, K3G, M4V, M4A, M4R, M4B, F4V, F4A, F4B, GIFV, QT, MQV, ISMV, and ISMA with a maximum file size of 20 GB. 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 and AAC or PCM audio codec.

Clever Online Video Repair continually strives to expand the list of supported formats to meet our users' needs. That’s why we have added experimental support for repairing almost 400 file formats: 3dostr, 4xm, a64, aa, aac, aax, ac3, ac4, ace, acm, act, adf, adp, ads, adts, adx, aea, afc, aiff, aix, alaw, alias_pix, alp, amr, amrnb, amrwb, amv, anm, apac, apc, ape, apm, apng, aptx, apv, aqtitle, argo_asf, argo_brp, argo_cvg, asf, ass, ast, au, av1, avi, avif, avm2, avr, avs, avs2, avs3, bethsoftvid, bfi, bfstm, bink, binka, bit, bmp, bmv, boa, bonk, brstm, c93, caf, cavsvideo, cdg, cdxl, chromaprint, cine, codec2, codec2raw, concat, crc, cri, dash, data, daud, dcstr, dds, derf, dfa, dfpwm, dhav, dirac, dnxhd, dpx, dsf, dsicin, dss, dts, dtshd, dv, dvbsub, dvbtxt, dvd, dxa, ea, eac3, epaf, evc, exr, film_cpk, filmstrip, fits, flac, flic, flv, frm, fsb, fwse, g722, g723, g726, g729, gdv, gem, genh, gif, gsm, gxf, h261, h263, hash, hca, hcom, hdr, hds, hls, hnm, iamf, ico, idcin, idf, iff, ifv, image2, imf, ingenient, ipmovie, ipod, ipu, ircam, iss, iv8, ivf, ivr, j2k, jpeg, jpegls, jpegxl_anim, jpegxl, jv, kux, kvag, laf, latm, lc3, libgme, libopenmpt, live_flv, lmlm4, loas, lrc, luodat, lvf, lxf, matroska, mca, mcc, mgsts, microdvd, mjpeg, mjpeg_2000, mkvtimestamp_v2, mlp, mlv, mm, mmf, mods, moflex, mp2, mp3, mpc, mpc8, mpeg, mpeg1video, mpeg2video, mpegts, mpegtsraw, mpegvideo, mpjpeg, mpl2, mpsub, msf, msnwctcp, msp, mtaf, mtv, mulaw, musx, mv, mvi, mxf, mxf_d10, mxf_opatom, mxg, nc, nistsphere, nsp, nsv, null, nut, nuv, obu, oga, ogg, ogv, oma, opus, osq, paf, pam, pbm, pcm, pcx, pdv, pfm, pgm, pgmyuv, pgx, phm, photocd, pictor, pjs, pmp, png, pp_bnk, ppm, psd, psp, psxstr, pva, pvf, qcp, qdraw, qoa, qoi, r3d, rawvideo, redspark, rka, rl2, rm, roq, rpl, rsd, rso, rtp, rtp_mpegts, s16be, s16le, s24be, s24le, s32be, s32le, s337m, s8, sbc, sbg, scc, scd, sdns, sdr2, sds, sdx, segment, ser, sga, sgi, shn, siff, simbiosis_imx, sln, smjpeg, smk, smoothstreaming, smush, sol, sox, spdif, spx, srt, stl, stream_segment,s, sunrast sunrast sequence, sup, svag, svcd, svg, svs, swf, tak, tedcaptions, tee, thp, tiertexseq, tiff, tmv, truehd, tta, ttml, tty, txd, ty, u16be, u16le, u24be, u24le, u32be, u32le, u8, uncodedframecrc, usm, v210, v210x, vag, vbn, vc1, vcd, vidc, vividas, vivo, vmd, vob, vobsub, voc, vpk, vplayer, vqf, vvc, w64, wady, wav, wavarc, wc3movie, webm, webp, webvtt, wsaud, wsd, wsvqa, wtv, wv, wve, xa, xbin, xbm, xmd, xmv, xpm, xvag, xwd, xwma, yop.

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 files, followed by downloading the repaired file. The actual repair time depends heavily on the file size and can take anywhere from a few seconds to up to an hour for very large files. 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, using online services like Clever Online Video Repair is generally safer than installing software from untrustworthy sources. Our platform ensures secure sessions where you can monitor which devices access your account. Be cautious of sites that claim to repair videos online but require you to download and install software, as this can be a potential security risk.
No, creating an account is not required to repair or upload a file. However, please note that without registration, you can perform only up to three repairs, and your files will be deleted from our server after 24 hours.

By registering, you’ll be able to perform up to 10 repairs without deletion, store files for more than three days, view your repair history, delete repair tasks, upload and access repaired files from different devices, protect your tasks with a password, manage sessions, and delete your account.
Yes, Clever Online Video Repair is fully optimized for use on modern smartphones. This allows you to repair videos directly from your mobile device. With an account, you can access your repaired files anytime from any device, ensuring convenience and flexibility.
Yes, there is a file size limit of 20 GB on Clever Online Video Repair. You can repair up to three files of this size without registration, and up to ten similar files after creating an account. Delete previous repairs to free up space if you need to repair more files.
Clever Online Video Repair first analyzes the integrity of the uploaded file, collects technical data about its structure, and selects the most suitable repair method for the detected issue. In most cases, no sample file is required, as we automatically detect the codec settings. However, if detection fails, you’ll need to provide a sample file recorded with exactly the same settings as the corrupted one.
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, f4v, f4a, .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 sample from the same camera and recording mode; however, Clever Online Video Repair is capable of repairing files without a sample.

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 choosing a video repair service, pay attention to whether it can repair files without a sample, doesn’t require mandatory registration, is easy to use, and provides a high-quality preview of the repaired file so you can verify its functionality before making a payment.
Clever Online Video Repair uses dynamic pricing, so the exact cost is determined only after you upload the file.

Please note we have a strict no-refund policy. We can only recover data that exists in the file but is unreadable; if parts are missing, there is nothing to recover. Carefully check the video/audio duration and the preview quality before paying to avoid losing money.

We do our best to analyze a file’s playability. You can check the file locally with VLC media player. If the uploaded file does not match the preview, please contact our support team.
If you haven’t registered on the website, your temporary files will be automatically deleted after 24 hours.

To delete your account along with your repair history and temporary user files used during repairs, you first need to log in to your account at repair.cleverfiles.com. If you signed up using your email instead of a Google or Apple account, your password can be found in your registration email.

Logging into your account is required to confirm that you are the account owner and to protect your data from unauthorized access.

Go to Dashboard → Settings → Profile. There, you will see a large red Delete account button. Click it and confirm that you really want to delete your account.
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 are completely free tools available for video repair, such as Untrunc, but they require using the command line and compiling for certain platforms, which can be challenging for most users. In addition, Untrunc needs a working sample file from the same video source.

Clever Online Video Repair, on the other hand, can repair both video and audio files without a sample and achieves a much higher success rate than free tools.
Most video repair programs cannot fix a corrupted file without a working sample of video or audio recorded with identical settings. This is the key difference from Clever Online Video Repair, which usually doesn’t require a sample thanks to its automatic parameter detection.

Additionally, most desktop repair tools lack a user-friendly interface, making them difficult to use. You have a higher chance of successfully repairing your media files online, as online services are updated more frequently than traditional computer programs.
