Limits

Starting point: HEVC - HEVC is the H.265 codec halving bitrates versus H.264. Raw streams lack timing, so set frame rate by hand. Seek indexes can be sparse, so verify duration after conversion. Encode F4V (H.264 / AAC) from HEVC at a bitrate near the source, and confirm the audio track before converting.
