  • Hi I wondered if anyone might help a 'video codec' noobie with a few questions? I try to do my own research thats what the internet is for but I think I need a few pointers. I am mixing footage taken with a Nikon SLR 1280 x 70 with various scenes…
  • @Triem23 Thanks - yes I intend to start experimenting with use of proxies.
  • @jsbarrett Thanks for the reply - nested composites! Yes I have previously successfully made a composite from untrimmed videos and then trimmed them in the composite. I am now roughing  out a sequence on the regular editor, this decision was a mi…
  • @Palacono Thanks for the tip, I took a look I could not easily find out but I am fairly confident that they would probably not support Nikon NEF raw format. My need for highest frame by frame quality probably means I am stuck with Nikon software, …
  • I tried looking at the screen (previous posted video) holding both hands to my face to view only a small area at a time. The jerkiness seems to be much more associated with the background. When I cup my hands with a small gap so as to visually iso…
  • A note on histogram. When I first started to even out exposure I was looking primarily at the frame itself, flipping frames back and forth looking for flicker and adjusting until I felt I had reduced fliker significantly. Later I paid more attenti…
  •  Latest attempt. https://youtu.be/NnEhYEK-s7g Shot at 4288 x 2848 Nikon D300s SLR exported at 1028p Youtube setting. Here I worked hard on equalizing out the image brightness on a frame by frame basis working on the Nikon RAW images. Nikon softw…
  • @JMcAllister Oh yes - sorry my mistake. "that filmmakers have (always?) taken liberties with physics" And lighting conditions ! Edit: I meant lighting conditions in deep space - would we really waste precious energy floodlighting the whole ship?
  • Today I tried to improve slider so that it moves with a little more ease, and I need a scale to measure distance, looking for really simple solutions so this ended up being a 1mm thick plastic sheet to minimise friction and a tape measure stretched …
  •  @dplester thanks! At the moment I am adjusting shutter speed not aperture control in manual mode. Whilst I have been working on this weather conditions mean that the light levels are varying - several stops between frames. I am rapidly coming t…
  •  @JMcAllister I would have to disagree DOF is an artifact of lenses, also film makers have taken liberties with physics for a long time https://en.wikipedia.org/wiki/Depth_of_field I suppose an argument in the other direction might be that after…
  • @Tddavis - comment from a newbie. The asteroid field looks great! I wonder if the next step might be to decide on a focus point, depth of focus and so on and to defocus specific elements by carefully judged amounts. Naturally being a video newbie…
  • Stabilization Software or Hardware? By hardware stabilization I mean a precision built rig perhaps using buggies and rails from the world of CNC* which was a possibiliy floating around in my mind but I believe it is not necessary. By software stab…
  •  Thanks - if I cannot remove all the flicker then I will call it an atmospheric effect. Read a few articles online from stop motion animators preferring some artifacts to keep it 'real'. I aim to repeat at half the step length for a smoother ride…
  • https://www.youtube.com/watch?v=zTt9kQn7gUg Same frames but this time processed from the Nikon RAW files (.nef) using viewNX which has very rudimentary adjustment capability - I tried to even out the uneven lighting by eye, I think I can do better …
  • Perhaps a half way solution between virtual and physical Construct a 'rocker' consisting of two sturdy plates at 90 degrees to one another and paint that green - literally what you would get if you took two adjacent faces of a cube and threw away t…
  •  Another known imperfection which does not concern me at this trial stage. The usual domestic distractions meant I took some frames more than once, I forgot where I was in the process. There is some stutter due to these duplicates which I should h…
  • First result https://youtu.be/LyRXDjnonAw Shot at 4288 x 2848 Nikon D300s SLR exported at 1028p Youtube setting. Camera exported RAW and jpg but for simplicity I just used the jpg with no adjustment out of the camera. Remember to view in HD and …
  • My first trial on Youtube. https://youtu.be/LyRXDjnonAw 24 fps - taken at 4288 x 2848 - video exported at 1080p HD I set my Nikon D300s to export both jpg and RAW (nef) but for a quick first result I just took the jpg's direct from the camera wit…
  • @Stargazer54 I have italicised background blurb which most will want to pass over "This might be help  others who seem to struggle with the software" I might have a slight advantage compared with some other newbies as when I had a "proper job" ( …
  • Hmm there seems to be a bug on this forum. It seems that if you re-edit a previous posting you can lose the posting you most recently added. I see a message along the lines that my posting is awaiting approval after multiple edits with the spurious…
  •  Another attempt to get the photos visible. The Bracket The Bracket On The Tripod Fixed To Saw Bench The Slider - two knobs to tighten. The scrap sheet I had lying around for the slider base fortuitously had an accurately bent 90 degree tu…
  • Interesting! First 'rough' attempt taking actual footage. 30 frames - little over a second. I will not be posting this very first attempt yet, it was done in a rush just as natural light was disapearing. Observations: 1. Positioning the slider …
  •  @JMcAllister Sorry about that - they are hosted on Google photos - I wanted to upload the photos directly to this forum but it seems to accept only URLs rather than allow upload of the photo itself from local disk which would have been my first pr…
  •  Today's progress. Mounted on saw bench The slider not yet painted, two screws to lock down Slider - two screws to tighten At the moment the camera and tripod would fall off if the two screws were loosened completely so I think a safety is in or…
  • I should add that I placed the post in 'users Gallery' because I hope to add footage taken using the rig at a later time.
  • @jsbarrett Hi thanks for that. So far it seems to be working out fine following your instructions, I edited a number of related clips almost as a 'project within a project' and the resultant composite seems to load into the 'main project' without …
  • @Axel and Triem23 Does the advice offered here not contradict what Axel wrote in https://hitfilm.com/forum/discussion/1360/when-to-use-composite-shot? Axel says in the current thread..".One is to place them both into a composite shot."  Triem23 …
  • Thanks Triem23  Yes PNG is my preferred 8bit choice. Yes I am sure it will be a lot of fun I am quite looking forwards to it - the biggest issue will be whether in natural lighting I can achieve 3x24 frames within  a stable light condition - howev…
  • @CedricBonnier yes its hard to know whether "yours to keep forever" can be guaranteed even if we dismiss the obvious issue of current version of OS or hardware simply being unable to run software anymore which is outside the  control of the app sof…
