Speaker 1: So I use Riverside as my main online platform to record my interview content whether it be audio or video and audio at the same time and record it in HD. It's a great tool that gives a lot of flexibility and quality in the edit that other tools like Zoom or Teams just don't provide us unfortunately. But here's a little tip to make sure that we have all the frequencies available to us when it comes to mixdown and maximising the quality of the content that we're recording. Okay so let's assume that we've recorded our interview and we're going to now go into the studio recordings. Let's open this tab and then on the right hand side you'll see here it gives us the option to download in high quality. So we can download the raw video, the raw synced video if it's an interview, the raw audio itself and then compressed audio in lower quality mp3. So first off if we download the raw video in mp4 that's great and it's recorded in HD but you'll see in a minute that the audio quality there isn't exactly what we need it to be. So then we can download the raw audio separately. I'm going to open up iZotope RX now and you can see in the spectrogram the difference. So this is the mp4 opened up in iZotope RX. So I've actually got the frequency scale set to linear here so you can really see the difference. I normally have it with extended log which actually gives us a lot more clarity in the lower end but just to show the point here of what we're missing I'm going to show you in linear. So this is the mp4 as I said. Everything from about 16.5kHz upwards is gone. It's just not there. In theory as dialogue we shouldn't be able to hear that but that extra 4.5kHz that we're losing actually gives us a lot of possibilities with the air. But you can also see the degrading of quality in the waveform as well in the spectrogram. So then if we open up the wave file it's exactly the same file but in wave format. And again versus the mp4 we can really see the difference. Everything above 16.5kHz is completely gone and here it's back. So what's great about that is if we want to add a lot of high end to our dialogue or top end we can add that air without really starting to hear synthetic frequencies or fake frequencies. The same applies for the bottom as well. So if we go back to the mp4 you'll see that degrading quality here. Then we'll open up the waveform. So we can see that the frequencies in the waveform are a lot cleaner than versus the mp4. So what we'll do from here is open up Premiere Pro, load in the mp4, mute the audio for the mp4 and then load in the waveform and only use that audio. So when it comes to mixdown we can export the OMF and make sure they've got the highest quality audio possible.
