Can Handbrake Convert MKV to MP4 without Losing Quality?

Before anything else, there is one thing we have to mention. Many people are expecting that HandBrake can help convert videos from .mkv to .mp4 without quality damage, but they are most likely to get disappointed because video conversion in HandBrake is a process of converting one encoding method to another method, which involves quality drop to some degree.

Though HandBrake gives a “lossless conversion” option by setting constant quality value as zero, you will get an extremely large file that is impractical in actual usage. Yet, if you know how to set the best settings for converting your videos, you can minimize the quality damage. The next part will show you how to achieve that. Just read on and follow.

Step 3: Move to Dimensions where you can resize the video by typing in desires values into the Width box and Heigh box if you don’t want to keep the original display size.  Leave the other options at their default value if you don’t have particular needs.

Adjust Handbrake Settings

Step 4: Go to the Video tab, select H.264 (x264) or H.265 (x265). These two codecs are advanced standards for efficient video compression and can greatly reduce video file size with the same video quality. At present, H.264 is the standard for streaming.

Step 5: Next, move to Quality section, drag the Constant Quality slide bar to the right to set an appropriately lower RF value. The lower the RF value is, the higher quality the converted video will be yet the bigger the file size you will get. Quality scale ranging from 18RF to 23 RF is sound.

Step 6: Head to Optimise Video section under Video tab and set the Encoder Profile as High.
