00:00:03,359 --> 00:00:14,979
So, the first step to use this software is to log in and if you have just created a new account you will see here that you have 100 credits.

2
00:00:15,680 --> 00:00:22,920
So this is the demo mode, so the first thing we want to do is to add some credits for free.

3
00:00:22,920 --> 00:00:30,979
We can do that by clicking this button and then clicking on refresh credits.

4
00:00:32,819 --> 00:00:37,220
Now we have 600 credits and we can get started.

5
00:00:37,779 --> 00:00:48,319
So I will show you how to convert a university lecture into a polished video and in the support material.

6
00:00:51,000 --> 00:01:03,599
In the interest of keeping this tutorial short I have just taken a segment of the lecture but of course the procedure would be the same for a full lecture.

7
00:01:04,959 --> 00:01:19,180
The first step is to go here in video upload and drag and drop the file that you want to. In this case we are going to process a file about fuel cells.

8
00:01:26,379 --> 00:01:35,319
Once the file is loaded, if we want we can see the preview of the original file here, you can play this.

9
00:01:36,160 --> 00:01:47,000
But what you essentially have to do is to click run full processing and wait that the app does its job.

10
00:01:48,779 --> 00:02:03,019
Depending on the video duration the process can be longer or shorter but you will have an update on what is going on here and you can see this running icon that tells you that the app is working.

11
00:02:03,019 --> 00:02:09,020
So basically now we just have to wait this out and see what happens.

12
00:02:18,316 --> 00:04:13,637
Okay so now the processing has finished, we can see that there are no messages here and the running icon has disappeared, and we have here the preview of our revoiced video, which we can play. Okay, so today we are starting a new chapter in our course and this one is about fuel cells. Fuel cells share some characteristics with batteries. Obviously, you now hear it with the same voice that you are hearing for the tutorial because I have actually produced this tutorial using the Video Distilled software. Now let's look briefly at the interface. Here we have the preview of the revoiced video, here we have the transcript of each slide that has been identified in the video, and this is the text that is actually being pronounced by the AI-generated voice. If you want to change this text, there are two ways of doing that. The first one is automatic by changing these settings. Here, in the transcribe settings, we can modify, essentially, the slide detection settings that are used to identify the slide in our presentation, so each slide change is a peak on this graph, and you want to have this horizontal line to cross the peaks and not the noise.

13
00:04:14,597 --> 00:04:27,017
And then, you can change the style of the AI-generated text by changing these values in these menus.

14
00:04:27,677 --> 00:04:39,917
So, in this case, I didn't make any substantial change, the change level was moderate, and I have chosen to keep the style similar to the original.

15
00:04:39,917 --> 00:04:51,817
But, if I wanted, I could change the style in Academic and then decide, for example, for a semi-informal tone.

16
00:04:54,037 --> 00:05:00,377
Also, here, we can optimize for clarity and flow or optimize for lip-sync movement.

17
00:05:00,377 --> 00:05:10,197
Now, in this case, we optimize for clarity and flow because there is no visible speaker in this.

18
00:05:10,937 --> 00:05:18,957
If I was to hit transcribe now, all this text would be regenerated according to these settings.

19
00:05:19,557 --> 00:05:36,997
So, I would get a different text here and then, if I wanted to create a new video, I would go here in revoice, click revoice, and this would regenerate the new video with the new text.

20
00:05:39,237 --> 00:05:45,137
I'm not going to do that now because I want to show you what can be downloaded.

21
00:05:46,257 --> 00:05:52,037
We can download the transcriptions and the slides that we have detected.

22
00:05:57,015 --> 00:06:29,495
We can download the revoiced video, which is the one that we see in the preview, and finally we can download the supporting material that goes with this particular lecture and includes lecture notes, lecture summary, a script, if one wanted to re-record it with their own voice, and some essay-type questions and multiple-choice questions.

23
00:06:32,716 --> 00:06:48,876
There are also more things to look at, such as the audio review tab or the expert mode, but in this simple tutorial we are not going to look at it in great detail.

24
00:06:55,576 --> 00:06:55,716
Thank you for watching!
