Hi everyone, in this video we are going to look at something called Interpret Footage. What it's used for, it gets used for many things, but mainly in slow motion. That's why it's in this part of the course, let's dig in.
So the long way, and the painful way is, I've got this bit of footage here, it's slow motion, let's play it, it is 24-ish frames/second. So the slow motion is exposed, this one here, in Slow Motion 03 has all these frames, has four times the amount as this one-ish, but it plays back at a regular speed, you see, just like normal speed, 100 frames/second. "Ready for my flip?" There you go.
So it is, the slow motion is trapped inside of here, so it doesn't really matter which way is which, it's just the way it's been output, from either the camera, or the videographer's decided to kind of remap it afterwards. Either way, let's say you want Slow Motion 02, and you're like, "Okay, good," I want it to go to just regular speed, you right click it and you say, 'Speed/Duration', and then you guess what speed it should be.
It's either 50 frames, so you double it, so 200 times, it might be 60, it might be 100. I've worked out just by trial and error, that four times the amount of speed, which gives me roughly 100 frames/second, is what this was recorded at. I don't know for sure, because I don't have the details from the shoot, I wasn't involved with it, and I can't find anything for it, so there's a bit of guessing. If you do know a magic way of knowing what the frames/second is, let us know in the comments, but anyway we've done it, and we can happily go about our work.
The problem happens, is when you've got like the whole photo shoot. So in this case, you see these, that's, I've given you Slow Motion 02, from one of all of these. So every single one of them is a slow-mo. So if you're dumping and doing a cut, it's painfully slow. So what you do is you interpret the footage. I'm going to call this, actually I'm just going to delete that sequence, start again.
So 02 now, instead of dumping it in and changing it, what we do is we say, we right click it, we can say 'Modify', and we say, I want to interpret this footage. Now what is Interpret Footage? It was used originally when-- it was really, in the early days of digital video, lots of codecs and different extensions, Premiere Pro would sometimes get it wrong, it would say, "Hey, I've imported your mp4 as a square pixel," but it actually wasn't, the Aspect Ratio was something else, it was something like this, you could force it, you could just say, "Hey, Premiere Pro, good try, but can you reinterpret this footage for me, and I'm going to try these," and it ended up fixing it.
I find that happens less and less, Premiere Pro, super good at interpreting the footage on its own, but you can fake it, but if you do have problems, you might come in here and change with some of the parts. In this case I wanted to say, I want you to interpret this 23.9760 PAL, man, I hate that number. I want you to assume, just assume, it's 100 frames/second please, thank you very much, click 'OK'. You see, it's changed here, the Frame Rate is 100 frames/second. Now if I make a clip from it, it's used my sequence, is 100 frames/second, it's trapped in there still.
I can slow it down, like I did by going, right click and say 'Speed/Duration', and I can slow it down by 1/2 speed. So I've still got a bit of slo-mo in there, but it's my choice, I can do it later on. So I start with the regular real-life video, and I can slow it down if I need to, a lot-- I'll end up shooting high frame rates, because it kind of looks nicer, but with the idea that, especially B-roll, I'll just shoot everything in like 120 frames/second, even if I don't plan on using it, just so it's there. So I've got it, so the file size has ballooned, and my editor hates me, but it's in there in case we do want to slow things down.
So why is that quicker? It is mainly quicker when you have to do all of these, let's say we want to dump it all in, and it's just the beginning of a job, you're like, "Great." It's all slow motion, let's have a look, a couple of them, they're all slow motion, lots of shots, and instead of going through, dumping them on a Timeline and doing it all, you can just right click 'More', all in one big go and.say 'Interpret Footage', and let's pretend it's 100, give it a test, all done in once. Yeah, it's quicker, it's easier, if you are only doing one or two shots, it doesn't matter, but Interpret Footage is good for doing bulk stuff .
All right, that is it for Interpret Footage, let's jump into the next video.
