Good job with large files
GoTranscript did a great job of transcribing three .mp4 files. They were able to decipher some areas of hard to understand voices as well as the technical terms used. Had a problem with the transmission of the original files to them (two were over 3 GB in size), but they were very cooperative in figuring out how to get the the files to them via an alternate method. My advice is to send them as small a file as you can (by degrading the video quality). The smaller files do not adversely affect the audio.
