Before starting the operation, there is one thing we have to mention. Many people are expecting that HandBrake can help convert MKV to MP4 without quality damage, but we do not recommend this for the reason that video transcoding in HandBrake is a process of converting a video format to a different and compressed version and the compression is typically lossy to different degrees. Although HandBrake indeed gives lossless conversion option by setting constant quality value as zero in it, you will get an extremely large file, which is impractical in actual usage. But it is possible to minimize quality damage in HanBrake by applying the optimum setting for converting your videos. Here is how you can convert MKV to MP4 in good quality.

Step 1. Open HandBrake, select Folder to add a folder containing multiple MKV videos or select File to import a single MKV video for conversion.
Step 2. Click the Format button under Summary, select MP4.
You can also select the check boxes below for different usages. There are Web optimized, Align A/V start, and iPod 5G support. Hover your mouse over the corresponding options, it will display detailed information on these options.
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.
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.
Step 7. Click on Browse at the bottom and designate the output path.
Step 8. Click Start Encode on the top menu bar to start MKV to MP4 conversion.
