CaptionSync accepts a variety of media files for Closed Captioning. This article shows how to use Any Video Converter to transcode your files into a different format.
While the limit for uploads via our website is 2 GB, and there is technically no size limit for uploading via AST-Link, there's still a maximum amount of content we can store during the download of your files. In general, if your file is larger than a couple GB, it is probably not reasonable to try to upload it -- just create a small "proxy" of the video (that is, either a low-resolution video, or an audio-only version - mp3). A "proxy" ( a smaller version of the film) maintains the timeline of the video, so the caption files that come back are exactly the same as if you had uploaded the full video. For content where the transcriber does not need to see the video to transcribe it accurately we only need the audio of the media files, so in fact uploading an .mp3 audio file is all we need in many cases.
Any Video Converter is a reliable converter that comes in both PC and Mac versions, and it's free. You can download and install Any Video Converter from their website.
Video Tutorial (This video is an alternative to the Text Tutorial)
- Launch the Any Video Converter (AVC) application, then drag and drop your video file into AVC. You can also go to File menu -> Open, or click the Video button and browse to your video file. If your video is online, click the Download button and paste the URL to the video file.
You may add multiple video files of different formats that you wish to be converted at the same time.
- From the Output drop-down list, scroll to the Audio Formats section or click the music icon and then select MP3 Audio (*.mp3) from the list.
- In the Save to (Output Folder) field, enter the path to the location where the output file should be stored. Click Confirm to save the settings.
- Click Convert Now to start converting your videos.
Once the media has been converted to MP3 audio, you can submit it to CaptionSync.
You can use the process described above to convert a video into a smaller format to use on your Apple devices, like the iPhone. Choose the Apple iPhone MPEG-4 Movie format from the Output drop-down list (Apple Products section). On the right-hand side, under Basic Settings, set the size for the new output next to Video Size, e.g., 480 x 320. Then proceed with converting your video.
