If you don't have the time or space to render a temporary lossless copy of your file on disk, you can use a frameserver instead.

If you only want to encode the first several seconds of a video, perhaps to compare it to another video, you can use ffmpeg -t 120s -i ....
@jeffward01 Best of luck. The output codecs I listed above are typically lossy (H.264 and H.265). If you want lossless, or at least very close to lossless, you may want something like Ut Video, Apple ProRes, or Avid DNxHD instead. The best explanation of this concept that I have found is Warren Young's comprehensive answer to "How to create an uncompressed AVI from a series of 1000's of PNG images using FFMPEG".
