  My stitched frames colors looks very different from my original video, causing my video to not be able to stitch it back properly [closed] - Wer Wer Newest 'ffmpeg' Questions - Stack Overflow
  I am trying to extract some frames off my video to do some form of steganography. I accidentally used a 120fps video, causing the files to be too big when i extract every single frame. To fix this, I decided to calculate how many frames is needed to hide the bits (LSB replacement for every 8 bit) and then extract only certain amount of frames. This means if i only need 1 frame, ill extract frame0.png ill remove frame0 from the original video encode my data into frame0.png stitch frame0 back into ffv1 video concatenate frame0 video to the rest of the video, frame0 (...) -- Frame0.mkv, original.mkv, results.mkv

  Moviepy not updating FFmpeg Version after FFmpeg Install? - The_ Game12 Newest 'ffmpeg' Questions - Stack Overflow
  I've been toying around with MoviePy, and recently switched a project to a new computer at home to continue messing around with it. However, I tried running what I had previously written (which ran perfectly fine on the other computer) and I get this: OSError: MoviePy error: failed to read the first frame of video file ./Gameplay/minecraft- gameplay2.mp4. That might mean that the file is corrupted. That may also mean that you are using a deprecated version of FFMPEG. On Ubuntu/Debian for instance the version in the repos is deprecated.

  How to check 'Output bit depth' of the libx264 library in ffmpeg? - Greg Newest 'ffmpeg' Questions - Stack Overflow
  According to the x264 Encoding Guide, the crf scale depends on whether x264 is 8-bit or 10-bit. Supposedly x264 --help shows the Output bit depth. But on Windows ffmpeg -h full doesn't say anything about Output bit depth and the crf scale option is described as from -1 to FLT_MAX. How can I check if my ffmpeg is using 8-bit or 10-bit version of the libx264 library? -- x264 Encoding Guide
