  1. Fastest way is to use ffmpeg http://www.ffmpeg.org/. It's free and works fast since it just copies out the segment of video you specify without re-encoding. http://askubuntu.com/questions/59383/extract-part-of-a-video-with-a-one-line-command
  2. I modded by Sony NEX-5n with a remote switch port over a year ago. I've learned that the safest way to make sure your pictures come out throughout the jump is to put it on sports mode and set it to continuous shooting mode. You'll get one photo about 0.7 seconds. It's slow, but that's because the camera is actually adjusting the exposure and focus so pretty much all the pictures come out. It sucks that you don't get to take advantage of the speed priority ability of the camera, however, there is one benefit that I've discovered in my opinion. I took an old bite switch, stripped the wires and twisted them together to close the circuit. When it's plugged in and I'm ready to take pictures, I just turn the camera on and it will start taking properly focused and exposed photos. I like this, because I really only freefly these days and this way I don't have a dirty bite switch in my mouth, and I don't have to keep remembering to take the shot. I just focus on my flying, and in the end I can just turn the camera off to stop taking photos. Sure I could do the same thing with my Hero3 (now), but I really like the photo quality of the NEX and the 16mm lens. It's also more dependable, since I can feel the shutter going off through my helmet. To be honest, I don't really recommend anyone follow my route, but since you're practically almost there.. I figure why not. Here's some NEX photos from about a year ago: http://www.facebook.com/media/set/?set=a.316165238467291.74295.100002214539052&type=1&l=065733b0ea
  3. It's doable, but the angle of the camera platform is pitched downward for freeflying. You'd have to come up with a way to pitch it upward to film tandems (perhaps with a custom bracket). This is from my experience though, perhaps it will not be an issue due to the way you fly when filming tandems.
  4. Latest firmware update adds 1080/60p support, better underwater white balance: Some info, plus press release: http://www.engadget.com/2013/04/30/sony-action-cam-software-update-1080p-recording-60fps/ Link to update: http://esupport.sony.com/news/466 I hardly use this camera, but at least Sony is still doing work on it.
  5. Actually, now that I think about it, the mirror was my favorite thing at Skyventure Colorado when I was tunnel training. If I had body position issues, I could always look at myself in the mirror and get sorted quickly. In some time, you may become the most awesome coach/freefall tool ever.
  6. Looks cool, but will it end up blinding people if they look at you while you happen to be facing towards the sun?
  7. Depends on what kind of jumps you are doing. If it's hop and pops, you might get 10 and those tickets are only $5 to 3k feet. However, full altitude jumps, you might get like 5 to 7 jumps in a day. They start about 9am and last load about 3:30pm.
  8. Hate to break it to you, but it's more likely they're referring to the end of the world, and not the beginning of the tunnel. End of the wait or end of the world... eh, either one works for me.
  9. This was just posted today on their facebook page:
  10. The YouTube video is blocked over copyright issues (in the US at least.) The only thing I really wish Sony would do for the HDR-AS15/AS10, is to increase the video bitrate. GoPro did this with the Hero2 through a firmware update. Here's a video that really shows how detail is lost when the scene is too complex: http://www.youtube.com/watch?v=sKUIYlqyRAc This shows up in the raw video, it's definitely not due to export process. The grass is just too detailed for the maximum bitrate that is allowed. Your wingsuit video is mostly blue sky, so the compression artifacts aren't really there, however, you can see the compression issue at the end when you are looking at your canopy on the grass. In your case, I think the camera does its job since it gets the wingsuiting footage pretty well and who really cares about looking at grass. If you were freeflying and were transitioning from headdown/headup with a few people on screen, you would definitely see the compression artifacts crop up.
  11. Would it be possible to take the lens from the Sony, and stick it on the GoPro? The Carl Zeiss lens is probably the only real good thing about the camera.
  12. Aside from the bitrate issues causing compression artifacts, the flaws (perhaps limitations is a better word) I was speaking about aren't dealbreakers. These are just issues I've encountered that others might run into as well. - No audio when recording at 60fps or 120fps. I want to be able to shoot at the higher framerate to have smoother slowmo capabilities when editing the skydive, but I'd also like to catch whatever the tandem might say on the way to the door. (Hero3 Black records audio at 120fps, so perhaps this could be changed on the Sony via a firmware upgrade.) - It's hard to hear the recording beep on the plane with the camera in it's waterproof case. I either have to have my cellphone on me with the Playmemories app working to make sure it was recording, or ask someone to look at the camera's rear recording light. It makes me appreciate the Hypeye, because I really don't want to have to carry my phone on me every skydive. - When I swap out the CX150 and place the HDR-AS15 on my top mounted camera bracket, the bracket ends up blocking the camera case latching. I have to remove the tripod screw that I use to mount it, so I can get the camera out of the case to change camera settings or copy data from the memory card. It's only a minor hassle, but it raises the chance that I accidently drop, and possibly lose my tripod screw. Not everyone is going to run into this issue, because it depends on how they choose to mount the action cam. On my Tonfly CX2, the HDR-AS15 mounted onto the zkulls using a tripod screw is actually pretty perfect; easy to flip the latching and get the camera out to adjust the settings. It definitely wouldn't be an issue if I used the sticky mount, but then I lose the flexibility of using my CX150 if the HDR-AS15 isn't working correctly. I'm sure if someone really wanted to lighten up their load, they could get this camera working well on their helmet setup and in their video editing workflow. My CX150 yields good quality while keeping things simple and reliable, so it's what I prefer/recommend for filming tandems.
  13. For fun jumping I plan on using the Hero3 Black, just because it was a lot easier to attach to my Cookie G2 and it's easier to change the camera angle for whatever type of jump I find myself on. I'd be careful of using the Hero3 for filming tandems though, because that battery drains pretty quick right now. It went from fully charged to dead in 2 or 3 days, despite being powered off and wifi disabled the entire time. The Sony's battery life has held up pretty well; when I turned it on, it had a strong charge despite being left off the charger for two weeks. I don't know if I'd recommend the HDR-AS15 for filming tandems either though, because it has its share of flaws as well. I'll probably stick with my trusty CX150 for tandems, or upgrade to a HDR-PJ710V if the price point is low enough after Sony releases next year's cameras.
  14. I shot some comparison video over the weekend, and I think the Sony Carl Zeiss lens delivers significantly sharper video than the GoPro Hero3 Black lens. That's based on my initial comparison though, the Hero3 was in Protune mode so I don't know if sharpening the footage would make them more comparable (I kinda doubt it). The thing that hurts the Sony though is the lower bitrate that it encodes at. At 120fps the Sony encodes around 24Mbps, whereas the GoPro in Protune mode is nearly double at 46Mbps. The Sony bitrate results in strong compression artifacts (evident in the youtube link below). http://www.youtube.com/watch?v=sKUIYlqyRAc Hopefully Sony updates its firmware to allow increased bitrate like GoPro did with the Hero2.
  15. They just released an updated version of the Playmemories Mobile app in the Google play store, and I was able to successfully connect the camera to my Samsung Galaxy Nexus and Asus Nexus 7.
