I wonder what according to you is the preferred choice of transcribing. Do you slow down the audio speed (for e.g. run at 50%) or do you run the video for a few seconds, pause for a few seconds and then rewind for a few seconds before playing again? I currently use Crowdsurf's newbie controls for transcribing and I have also transcribed videos by slowing down media files by 50% but that just seems too slow for me to understand very well. Any feedback will be much appreciated. Thanks.
