This question applies to all video editing software. I am looking to buy an HD Gopro Helmet camera, and I already have a Canon Vixia HF10. Coming up in this winter, I am going to be filming and editing a very big video in my community of Extreme Pogoers (sounds lame, I know, haha) and we are going to have an additional 2 HD cameras and another HD Gopro. Editing will be done in Vegas 8, with some additional shots composed in After Effects for things Vegas can't do.</p> <p>All of the HD Video cams look crisp and clean, while the Gopro shots are sort of blurry and softer. I decided to render in 720P, rather then 1080. Will rendering in a lower resolution make the Gopro footage look any better, or is there any way to make it look better, Rather then just having it as blurry as it is, but smaller? (If that makes any since)</p> http://www.videomaker.com/community/forums/topic/24p-playback-of-24p-video#post-54351 Sat, 23 Jan 2010 17:04:51 +0000 Mocojez 54351@http://www.videomaker.com/community/forums/ <p>I just watched the tutorial on creating a 'film look' using 24P, and I felt there were some misleading statements. I'd also like to add a very big comment about PLAYBACK.</p> <p>If there's no way to display or present your material at 24fps, I challenge the whole concept of shooting at 24P. Most decent video editing software now has the option to work in 24P format, so the material can be encoded to 24P MPEG-2 and displayed using HD DVD and a 24P-capable LCD screen (at a multiple of 24hz, with 120hz and above being optimal). You can also play directly from many cameras in 24P direct to these screens.</p> <p>However, if you have to convert to an NTSC broadcast format to display the 24P, forget it. A lot of material is still produced on film for TV broadcast, and they generally shoot at 24fps. I've even seen digital video shot at 24P for television broadcast, which is perverse. The whole system for getting feature films onto North American TV is a horrible compromise. The 3:2 pulldown 'expansion' of film frames to interlaced video is not part of the 'film look', especially since that effect doesn't happen in places with 50hz systems, like the UK. They don't watch movies on TV with any 'mashing' of frames.</p> <p>The TV production world uses 24fps for no other reason than it saves money, particularly in post production. I've seen many TV commercials shot at 24fps where the advertising agency actually believed they were producing a 'film look', which is a testament to the disingenuous nature of advertising.</p> <p>A couple of other comments:</p> <p>Motion blur is not the same as strobe - it's the opposite. Strobe occurs when the brain cannot perceive continuous motion, and this happens when we use a slow display frame rate COMBINED with a fast shutter (or narrow shutter angle in a film camera). At 24fps we don't perceive the black phases between the projected images - that's what persistence of vision means. But a narrow shutter angle means that each frame only captures a small percentage of the motion, and we can't put that movement back together in a fluid way. The narrow (or fast) shutter also decreases the motion blur, making things crisper, and this INCREASES the strobe effect.</p> <p>I also totally challenge the idea that you should add film grain, unless you want a 'vintage' look. 35mm film has more than twice the detail resolution of HD video, and a modern feature film shot on film and transferred to digital video has no perceivable grain, unless it was intentional. Grain comes from degraded stored print, or from high speed stocks 'pushed' in exposure, printing or development.</p> <p>And lastly, I wanted to comment that the 24fps standard for film-making is not set in stone. I agree that it was introduced with costs in mind, and then became a standard which was difficult to alter for the same reason. But movies are increasingly shot on digital video, and displayed on digital projectors. There's no doubt that a higher frame rate would raise the quality, so I predict that 30fps might be introduced in the near future.</p> <p>Movies certainly produce the highest quality of image, being processed in post production and projected in theatres at about 4K resolution, but we can only display those images currently on a TV screen at 1920 x 1080, so I have to ask why we trying so hard for a 'film look' in video at 24P, when HD video at 30P arguably looks better on a TV screen?</p> <p>I look forward to getting some comments!</p> http://www.videomaker.com/community/forums/topic/canon-hf-s10-lines-of-resolution#post-46740 Wed, 13 May 2009 08:34:26 +0000 flogonojo 46740@http://www.videomaker.com/community/forums/ <p>I have a question about the latest Videomaker review of the Canon HF S10. The review says the camera can capture 900 lines of resolution and that it's on par with a professional broadcast camera. But, I thought when the camera shoots in 1080 HD the lines of resolution would be 1080. So, different HD cameras, even though they shoot at 1080 HD, have different quantities of lines of resolution? If someone could expound upon this, that would be great!</p> http://www.videomaker.com/community/forums/topic/picture-mushy-edges-jagged-when-i-view-on-pc-monitor#post-48214 Mon, 22 Jun 2009 07:29:36 +0000 astrbac 48214@http://www.videomaker.com/community/forums/ <p>Hello everyone! :-)</p> <p> </p> <p>I am new to the forums and even newer to the world of moving pictures. I come from a still photography world, so I understand wuite a few things (like sharpness, tripods etc) but theres a lot more that I dont know.</p> <p>Let me explain the problem Im having. Today I shot some footage on a friends DV cam (Sony TRV950), in the local woods, during light rain. Trees, leaves, a bit of the wind sounds etc. Nothing too tricky I suppose.</p> <p>When I came home, I hooked this camcorder to my PC monitor (HP 2475w, excellent for photos, h-ips matrix) via A/V cable that has chinch connectors at the monitor end. Lo and behold, picture was not 16:9 even though recorded in that format and camera LCD showing it in that format, ...picture was all "mushy" (not out of focus but lacking detail, resolution?), edges were jagged (depending on the shot) sort of like a slight Moire  but not really it... I cant describe it, can it be that the resolution of this camera is not enough for 1900x1200?</p> <p>Thank you all and excuse my ignorance! ;-)</p> <p>P.S. Looking to buy a HD camcorder- what is the first lowest price range and model of camera that would allow for photo-like depth of field blurred shots? I have a dSLR photo camera so looking for something that would allow me to produce such a video that I can now do in my stills</p> http://www.videomaker.com/community/forums/topic/best-format-for-straight-to-dvd-production#post-39414 Wed, 20 Aug 2008 10:04:55 +0000 ehine11 39414@http://www.videomaker.com/community/forums/ <p>What is the best format (24p, 30p, 60i, etc...) and resolution (1080i, 720p, etc...) for a production that will not be sent to film, but plan to be a blu-ray and standard DVD release?</p>
