In this video, our friend Dave Dugdale compares the time it took him to transcribe a typical three minute video by hand verses using an automatic transcription service. As you likely know, automated transcription services use speech-to-text recognition technologies that at this point, are no where near 100% accurate. But does using an automated transcription service save you time, even when you may need to make corrections?

For those of you who may be unaware, there are a few tools available to provide transcriptions and closed captions for your video files.  As we've written about in the past, providing closed captions and transcripts are a great way to add rich on-page text for your video landing pages which is a good practice for video SEO.  Additionally and arguably more important, using transcriptions and closed captions help with accessibility.

Also, you can take these transcripts and upload them to your YouTube account as YouTube will then use Google's speech-to-text recognition technologies to transform your plain text transcript into closed captions for your YouTube video.  There are some indications (which I will cover in a post to come) that YouTube is using these closed captions to help better understand video content - which makes perfect sense.

SubPly, is a service that provides free automatic transcription and closed captioning for videos.  Despite Dave's experience that only files were accepted, I believe that the issue is more so related to the fact that SubPly only accepts FLV files at this time.  Unfortunately, they can not do mp4s.  Additionally, the free service is only available for videos that are less than 5 minutes in duration.  That being said, they do have professional products and services as well as an API for those who need transcription, closed captioning and/or translation for their online videos.  They have also partnered with several online video platforms like Brightcove to provide these services.

I hate to transcribe my own videos and I am too cheap to hire it out.

Mark Robertson at ReelSEO told me about an free automatic transcription service called SubPly, so I thought I would share my experiences with it and compare SubPly to transcribing by hand.

Let's get started.

Assuming you already have your video uploaded to a host like or you have the flv file on your server. Place the path of your flv file on SubPly and then wait. With this video it took 46 minutes before I got the email that it was done, sometimes I seen it work as fast as 5 minutes.

Once you get the email from SubPly that its done, head on back to your account and save a local copy of the transcript.

Then make the corrections you need to the text file by listening to your video.

For this 3 minute video it took 10 minutes to do around 80 corrections to the text file, sometimes SubPly got entire sentences totally right and sometimes I had to rewrite entire sentence from scratch. Mostly the corrections consisted of replacing words that it got wrong.

OK, there are two things I do with the finished transcription. The obvious one is place the transcript on my site next to the video and the other is to upload it to YouTube's caption feature which may or may not help my video rank better on YouTube.

I also add the text file to the video's description which in my experience helps get more YouTube traffic because of the longtail of all the words that now become searchable.

So, is it faster to do it by hand or use Subply? Well if you don't count the 46 minutes I had to wait for SubPly to do it's thing, then it is faster because it only took me 10 minutes of corrections with SubPly and 23 minutes to do it all by hand.

Couple of quick things to know. is the only service I can get to work with SubPly with the flv extensions and SubPly only take videos shorter than 5 minutes.

That's it - happy transcribing!
