Thread: Something's wrong with my videos

    Default Something's wrong with my videos

    Long time lurker, first time poster. I'm really quite a newbie at the whole HV20 thing, despite owning it for about 4 or 5 months, and for some reason I do think something is wrong with the way I'm either shooting, or capturing video. I'm pretty sure it has something to do with shutter and some settings, as some scenes are fine, and others have a TON of motion blur.

    Is during daylight. It's not that bad, but the motion blur does irritate me as I'ma perfectionist. I'm importing through Cineform Prospect2K and editing with Sony Vegas. I am doing the 3-2 pulldown.

    I understand I'm walking, but for some reason I don't think it should be that bad. There has to be some settings.

    So does anyone have any suggestions for me? Settings? Different modes? Also, is all the hope for my captured videos gone? Are they destined to be this..blurry...or is there some sort of program that can take away even some of this?

    Thanks everyone! If you want sources, I'll upload the raw x264's later tonight.

    The first one looked fine. They are race cars, they're gonna blur a bit. Adjust the shutter to be faster if you need to, but it will sacrifice some light. The second video suffers from a combo of handheld+slowish shutter, and possibly image stabalizer being turned off(?). You can't expect much of that one.

    I would recommend you get a tripod; that will help you get closer to "perfection".

    second the tripod or monopod (if you don't plan your shots, a good monopod is hard to beat.)
    handheld with fast pans....nope. thats blur waiting to happen.
    if you do want to walk and film, i think some type of steady-cam or fig rig would be in order.

    unless a buildings on fire or something else i can't prepare for, i always carry my monopod (manfrotto 560b) and my little gorrillapod.(i say little but it's not that little)

    Good one.

    P.S. Did you shoot in interlaced? Did you deinterlace with "blend"? Or was it PF24? In this case Cineform is not doing the best job. I can see ghosting in some frames.

    P.P.S. Why would you use PF24 for car racing?

    With that much movement in the city shot, stick to HDV-30fps and maybe shoot in 'Cine' mode since that is just a color effect (to put it very simply).
    OR, put it in HDV-30fps and Night mode or App Prio or Shutter Prio and find the right settings. You were in the dark anyway and the LCD screen will show your changes well.

    I could follow what was going on in the city shot, I've seen and shot worse. The pans and moves were a little too radical for the 24p especially at night.

    I just got a Bogen tripod from a garage sale for $5, I had a buy to QR plate and the 3 adjusting handles ($20 + $20 = $40 additional cost). NOW... I'm a huge fan of the tripod. I love it!!!

    This has nothing to do with 24P workflow and has been moved. Please post to the proper subforum, thank you.

    Do a search on "CMOS rolling shutter." Part of the problem is the progressive scan nature of CMOS sensors. Part of the problem is you need either a tripod or much, much better hand held technique.

    It's an HV20 so 30FPS is out of the question. I'd be willing to move to 60 if the blurring disappeared. I do like to shoot in Cine mode and I have had some pretty nice shots with the setting.

    I'm glad to see you can at least decipher what's going on in the city one. When I actually stood still or wasn't running the shots I got were amazing. One video in the subway was a map that my girlfriend was holding at a slight angle and you could read every stop. If I could make some sort of steady-cam rig it'd be ideal, or would something like THIS be worth looking into?

    I think that's part of the problem, along with my shakey hand. I imported one video without the Cineform automatic deinterlace, and it looked fine, but when the same video was told to be imported and deinterlaced, the blurring occurred. I don't know if it'd be smarter to use Vegas or Finalcut/Aftereffects to deinterlace, or if anyone has any suggestions there.

    On the 2nd note, I'm a complete novice in HD shooting, and didn't know any better!

    I have heard of it, and it does seem like I'm kind of experiencing it as well. The only reason I came in with the somewhat stupid questions was I used to have an Elura 100 for a few years, and no matter what you did with that thing it was fine. Walks in low light, jogging, cars, racing, you name it, it could handle it, but I'm just not used to having a beast like this. There's so many settings and programs you can use, just checking in to see if anyone had any tips. Didn't mean to come off as a pro or arrogantly.

    In addition to the rolling shutter, you have also gone up in resolution considerably compared to the Elura, so things that may have escaped detection are now more easily revealed.

    The Elura is low-res CCD, the HV is high-res low-bitrate long-GOP CMOS. Extra care is needed. For PF24 do not use "deinterlace" in Cineform, use "remove pulldown".

    Do a search on youtube for zero cost steadicam. That guy came up with a way to find and use the balance point of a fairly small lightweight tripod as a steadicam.

    I tried it and have used the technique several times with some degree of success. The more practice you put into it, the better it becomes.

    And you can take a look at www.spiderbrace.com - I just ordered their Spiderbrace II and am trying to get into practice using it with Canon HF100's (with www.hoodmanusa.com Hoodloupe 3.0 and velcro secured strap to hold it onto the LCD screen) and a Canon T1i Digital Rebel with CAVISION viewfinder assembly over the LCD screen on the back.

    In your footage I saw no indication that "rolling shutter" was a problem for you.

    Good luck.
