are a decent match to the original encoding. cut out the broken OP and replace it with the newly encoded gop (this will only work if the settings found in a. replace the corrupt frame with a copy of the intact frame. MP4 file) for video and audio chunks, tries to guess if a chunk is video or audio and so extracts all video and audio chunks for a new repaired movie. The video repair utility we developed, scans the movie (e.g. If the knowledge if there it's probably not really hard to do this, but from my point of view it's mainly a question of 'is it worth the effort' since doing the stuff I mentioned above isn't totally trivial and reencoding the source is probably less time consuming. open the file in an avisynth script, trim the source to the gop which includes the broken frame. The overall problem to be solved is finding the video and audio chunks in damaged and corrupt movie files. I don't know if your knowledge of video editing is broad enough to do this. are a decent match to the original encoding parameters) replace the corrupt frame with a copy of the intact frameĮ. open the file in an avisynth script, trim the source to the gop which includes the broken frameĬ. ReadMNGImage out-of-order CloseBlob call. detect the GOP structure of the file and the settings the first file was created withī. A memory corruption issue was addressed with improved memory handling. you can't fix this without reencoding at least the gop in which the broken frame isĪ. you now want to know if there's a way to replace the broken frame with a copy of the non-broken frameĪssuming that is what the first sentence was ment to say: this file has a corrupt Frame at around 2m 46s and the exact same Frame appears intact at 2m 56sĬ. you have an mp4 file which is 1h 40m long (with probably MPEG-4 AVC video content, since you mentioned h264encoder)ī.
