Limits
Starting point: AMV - AMV is the low-resolution player format for portable media devices. Odd frame dimensions get padded, so check borders after conversion. HEVC decoding needs newer hardware and encodes more slowly. Encode MP4 (H.265) (H.265 / AAC) from AMV at a bitrate near the source, and confirm the audio track before converting.
