Handbrake does not Remux MKV or MP4. REMUX: A rip of Blu-ray or HD DVD disk to another container format or just stripping the disc of menus and bonus material while keeping the contents of its audio and video streams intact, guaranteeing the exact 1:1 movie quality as on original disk.
Besides, you can also use Mac version of HandBrake to convert FLV to MP4 Mac. HandBrake is a tool for converting video from nearly any format to a selection of modern, widely supported codecs. Its Mac version can act as a free FLV to MP4 converter Mac. It is an open source yet free video transcoder. Step 2 Choose the output format as MP4 for the free FLV to MP4 conversion. Click the drop-down icon to enter the Format panel, select Video MP4 and the resolution. Before the conversion, you can click the Settings icon to customize the output format with a special frame rate, bitrate, encoder, etc. How to Convert FLV to MP4? Click the 'Choose Files' button to select your FLV files. Click the 'Convert to MP4' button to start the conversion. When the status change to 'Done' click the 'Download MP4' button. Handbrake works fine as well but creates mp4 file size 30% larger w/same quality IMO. Strange issue when using VLC File (tab) method as opposed to DISK tab. Open VLC, Click Media, Convert/Save then add all TS files from within the TSVideo folder (the BUPs/Backups are not recognized or included).
FLVs and MP4s are actually very similar. They both are simply containers for an h.264/AVC video track and a AAC audio track. So the only difference is the container itself. Thus, you can very quickly and easily switch containers without needing to re-encode the video or audio!
Step 1: Download FFmpeg. You can get the latest Windows version from here. Extract it somewhere that you will remember.
Step 1a (Optional): Add the /bin folder where you extracted FFmpeg into your PATH environment variable to make it easy to access (Control Panel > System > Advanced System Settings > Advanced Tab > Environment Variables > System Variables > PATH > Edit, put a semicolon at the end and type the new path)
Step 2: Open a command prompt and navigate to where your video is stored.
Step 3: Run the following command (If ffmpeg.exe is not in your path, you will have to type out its full path):
Replace 'input.flv' with the name of your source FLV file.
Replace 'output.mp4' with what you want the name of your resulting MP4 should be.
The '-c copy' means it will just copy the audio and video tracks without re-encoding them.
The '-copyts' flag means it will copy timestamps, which should help with syncing audio and video.
Step 4: There is no step 4. You're done! That was fast.
Speaking of HandBrake, it should be no stranger to you. It is a popular tool for DVD/video conversion, but sometimes the Handbrake output video and audio is out of sync, like the case below:
' I just started using Handbrake to change the video format from .mkv to .mp4 so I can play them on my TV. But now some of them have the audio and the video out of sync. The original video is good (.mkv files), but when I change the format, the new video is out of sync with the audio. I have tried to change the resulting format as well, to .avi and .m4v with no luck. The problem happens just as the video starts, the audio kicks in like 1 or 2 seconds before the video and it is like that until the end. Thanks a lot for your help.'
