When converting MP4 files, retaining subtitles can be tricky due to the varying ways they're handled. Tools like Handbrake, designed for general video manipulation, offer straightforward interfaces for destination selection when dealing with subtitles in MKV to MP4 conversions, though careful attention to settings is crucial.

On the other hand, FFmpeg's command-line nature offers flexibility but necessitates a deeper understanding of its parameters to ensure subtitle retention. Basic copy commands may not suffice, and specific options like `-c:s mov_text` might be required for embedding SRT subtitles. Interestingly, "hard" subtitles need to be re-encoded during conversion, while "soft" subtitles, if managed correctly, can avoid this step and potentially maintain quality.

The choice between embedding subtitles within the MP4 or keeping them as separate files can impact the workflow and outcome. If retaining multiple languages or formats is necessary, using MKV or MP4 as the output format within conversion tools might be more suitable. Tools like Wondershare UniConverter demonstrate how user-friendly interfaces can help simplify this process. However, it is important to manually verify that the correct subtitle track is selected in the interface during conversion to ensure preservation.

Batch conversion with FFmpeg is possible and can maintain audio and subtitles when carefully constructed. Using the `-map 0` flag combined with other copy settings can potentially simplify converting large batches of MKV files. But, remember that navigating multiple subtitle tracks during FFmpeg conversions might need specific filters and options as specified in the documentation, ensuring you're selecting the intended track for the output.

It seems that in some cases, achieving perfect subtitle retention and ensuring playback across various players and devices can be a difficult balance due to file size increase, timing sensitivity, and the need for correct encoding parameters during the conversion process. Overall, ensuring proper conversion parameters and careful selection of tools remains critical for subtitle retention and optimal video playback.
