  • Input MKV video info: 4K MKV (3846*2160), H.264 codec, 4 min 29s in length, 497MB in size, 15.5.Mb/s(overall bit rate), 23.97 FPS
  • Output AVI video info: 4K AVI, DivX codec, 4 min 29s in length, 51.9MB in size, 15 Mb/s, 23.97 FPS, No watermark

In conclusion: The VLC converting time is not impressive, indeed. Mainly because it only supports GPU hardware decoding, no GPU hardware encoding. Of course, if your MKV input is short in length, it's not a big deal and the converting speed is acceptable. As for videos like 30mins or MKV movie with 90 mins, you'd better resort to a professional MKV to AVI video converter with both GPU hardware decoding and encoding supported. Luckily, Winxvideo AI fits the bill!
