Providing a suitable Input File is important when using CaptionSync's Closed Captioning Video Encoding feature. This article details some troubleshooting tips for problems with the media files.
When you choose our Video Encoding service, the most relevant aspect of your submission is providing us with a suitable input file. The .mov, .m4v, .f4v, or .mp4 file needs to be properly encoded in the first place so that our automated system can appropriately encode the caption file into it.
If you receive a Video Encoding Failure Message, then please use one of the following methods to repair the input file and resubmit it.
Repairing Input Files using Any Video Converter (free software):
Learn here how to use Any Video Converter. Choose an MP4 output, and then customize it on the Options menus (bottom right-hand corner). Make sure the Video Codec (encoding) is H.264/MPEG-4 (Video Options menu), and the Audio Codec is AAC (Audio Options menu). You can change/select the other settings, and then generate different outputs until the results suit your needs. Then submit the media file to get Video Encoding performed.
Repairing Input Files using QuickTime Pro on a Mac:
If you're on a Mac and have QuickTime Pro, you can try to export it (Export option), and this will effectively re-encode the media file.
If Exporting the media file is successful, then it is likely that you'll get a properly encoded file from us, and you can resubmit the media file.
