Here is the test in flat anaglyph HD format, 9 sec at 2fps. Your browser does not support the video tag. Here is a b/w anaglyph cubic stereo face from my test. Postprocessing the video is more work or not possible.ġ3f.jpg. Careful adjustment of the camera rotation would have given the dancers more space to move. Here in the forward cubic face, in red, is where movement will happen.ĥ_12_348.jpg. Also to show that ffmpeg can be a tool in projects like this.Įq5.jpg. I take 8x2 still images around and from the final fixed position, an extra sequence of 18x2 images when the dancers walk over the stage. The one-line commands here should work on Mac and Linux, and on PC with minor changes. Here with still image formats to the final movie. Using PTGui and a late version of FFMpeg ≥ 4.3. That's in one of the six cubic faces that makes the sphere stereo panorama. Finally, while the learning curve is a bit steep, see this Regular Expressions Tutorial if you wish to learn more about regular expressions (regex) there are many other freely available regex tutorials on the Internet.The idea is to make a 360° stereo panorama video (or timelapse in this case as the video is restricted to 16x9 format with these cameras) where there is movement in only one area. Once you are happy with the results and comfortable using the app, you can go and change the names of the original files. If you are happy with the preview in the Renamed Filename column, click on the Rename button at the top right in NameChanger and you are done!īefore making changes to a lot of files, I suggest making copies a few of them under a new folder and trying NameChanger on those extra copies. If the two or more the files to be renamed have the same new name, the latter names are automatically added a number starting with 1 by the app. A new file name appears in Renamed Filename column for a file only if its name is to be changed based on the instructions you just put in. Once you do these, check out the preview in the Renamed Filename column. Put exactly the following in the Original Text field (the one on the left):Īnd the next one in the New Text field (the one to the right) as shown below: Then, select the Regular Expression function through the drop-down menu in the middle at the top of the app. You can also select the files you wish to rename through NameChanger's Add button. After installing and launching the app, select the files you wish to rename in the Finder and drag and drop them into NameChanger or right-click on them and select "Rename with NameChanger" in the context menu. In your case, I suggest using the Regular Expression function in NameChanger. I have been using it for a while and have been quite happy with it. Try NameChanger, a free utility for macOS.
