I recorded some long format talks in 1080i5994 DNxHD via my atomos recorder. I do this all the time and never have any issues. I record in that format because thats what my switcher puts out and it always just works. This time though, I recorded some screens from the presenters laptop which look fine on the recording. The recordings are all 100gb or larger so I can't upload that directly to vimeo or youtube. So I edited them and rendered them them to h.264 10mb but the smaller text on the screen is now blocky and unreadable. Larger text is fine though. What's a better way to do this in the future and is there a way to convert these so that the smaller text is still sharp?

I'm using Adobe Media Encoder with the vimeo preset. I've tried a variety of different settings and can't seem to get better results on the smaller text.

Here is the captured image. Orginial Capture

Here is the rerendered image quality. This is still a 6gb file for 1 hour. Rerendered Still

  • Which encoder? Deinterlacer? Settings? – Gyan Aug 19 '16 at 13:34
  • @ahackney can you share a frame grab of the output file that has the issue? – Michael Liebman Aug 20 '16 at 18:35

  • That almost looks like a scan converter doing some poor down-sampling, except for it not being present on the source. It won't get you to a good size for uploading, but have you tried an MPEG2 to rule things out? – Michael Liebman Aug 22 '16 at 22:50
