Slow-mo Practice

OK, I've been noticing what's new here on DVXuser is 'Real Time Slow-Mo'. So I thought I'd try it. I seen it done in a Twista video where he was rapping at normal pace while his surrounding were moving VERY fast, which was done by him rapping very slow, but I reversed and it rapped very FAST, for the slow mo effect. All of the settings that I used for my cam show b4 the video begins....Tell me if I did it right, tell me if I did it wrong..I'd preffer to know what I did wrong

Cool man. There's probably other examples of this as well but the first I remember is the Police video of "wrapped Around Your Finger". You should find it somewhere if you haven't seen it, it's from 1984 or so. Anyway, I may try doing something like that of me playing drums. How much practice did you put in to get through the song at that tempo??

I actually picked this song because this and Nas's-One Mic are my favorite Hip-Hop trax and I know every word of them by heart. So turning this up to 2.0 from the normal 1.0 on my media player and reinacting it was NO problem.​
 
The only setting I would change is the line detail. you have it set to thick, I would set it to thin. Not only does shooting with thick line detail give you less resolution but when slowing down footage you are essentially deinterlacing the footage, thus giving you even lower resolution. You need to start with as much res as possible. Otherwise, nice work, I'm impressed that you could keep up with all the words with the song sped up that fast.
 
Ditto the impressiveness that you could keep up with the song at double speed. I was however extremely irritated at the lens flare that was there throughout the video. Uggh. Good job otherwise though

Define 'resolution'​
 
The resolution of the DVX camera is the standard 625 lines (PAL) or 576 active lines (PAL), im unsure of the total lines for NTSC but its aproximately 100 lines less than the number of total lines in PAL, with the number of NTSC active lines being 480. By interlacing the picture, you are sending two fields of data every 1/25th (PAL) or 1/30th (NTSC) of a second from the CCD's to the recording medium which means when slowing down the video in post, the video will loose half the resolution, meaning every field becomes one complete frame. Forgive me if im wrong but essentially, in NTSC terms, it means each frame is actually only using 240 lines of the original picture (50%) with the other 240 being duplicated to make up the missing field. Therefore, it is best to try and avoid degrading the picture in any way before it reaches post production, with line detail being one of the most important factors for keeping as much resolution as possible.

I hope this explains things abit clearer but to be honest i have only repeated alot of what has already been said.

Didn't understand any of it. Sorry if you feel as if you've watsed your time But, Me, I'm a STRAIGHT TO THE POINT type of guy. You tell me what to do to not get that 'liney, wavy' video and I'll do it to fix it. THAT'S what I know...What switch, what setting..​

You need to do some more research then. If you don't have a guy doing the tech stuff for you you need to understand it so you know how to shoot correctly for different scenes.

Example, say you are shooting a piece that you want to be to turn to black and white in post.

It'd be extremely foolish to shoot in an enironment where there is lots of red, or have characters wear red because the DVX chokes....Red is the worst color to shoot with miniDV in terms of quality, you get lots of banding.

Know your camera, know how it works, take the time to learn it even if there are lots of big words and you are really confused about what's being said.
