Rephrase, first choice
A long compound can usually be said as two shorter words. That is an editorial change, made where the caption text is still editable, and it costs nothing in timing.

Generate an editable Malayalam caption track, then deal with the thing that makes Malayalam captions distinctive: the words themselves are long enough to break both recognition and line length.
Malayalam builds words by agglutination and compounding, and there is no fixed ceiling on how far that goes. A speaker can form a word on the spot that has never been written down, and it will be perfectly ordinary Malayalam. The vocabulary is open-ended rather than a list.
That creates the first problem. Research on Malayalam speech recognition points out that covering every possible wordform is impractical for exactly this reason, so a transcription draft is working against a harder target than it would be in a language with a settled vocabulary. When it gets a long compound wrong, the result is usually a plausible-looking word rather than obvious nonsense, which is what makes it slip past a quick read.
The second problem is physical. A caption line cannot break inside a word, so the longest word in a cue sets a floor on how short that line can possibly be. In Malayalam that floor is sometimes higher than the line limit you are working to, and when that happens no amount of clever re-breaking helps.
A long compound can usually be said as two shorter words. That is an editorial change, made where the caption text is still editable, and it costs nothing in timing.
It works, but it invents a cue boundary and redistributes duration. Do it somewhere you can watch the result against the video rather than in a batch operation.
Rather than reading the whole file looking for overflow, let a check find it. The subtitle validator reports every cue whose lines exceed the limit, along with reading speed, so you can see the scale of the problem before deciding how to handle it.
Then the subtitle line breaker will re-break everything that can be re-broken, without touching the timing. What it cannot fit, it reports and leaves alone rather than breaking mid-word or splitting the cue behind your back. In Malayalam that list is the shortlist of cues genuinely needing a rewrite, which is a much smaller job than reviewing the file line by line.
Start with the long compounds, since that is where a recognition error hides best. Then names of people, places and channels. Then English words spoken inside Malayalam sentences, which usually belong exactly as they were said.
Malayalam also uses conjunct forms, so a font without proper support can render them incorrectly while leaving every character present, the same shape of fault Bengali runs into. Confirm the file is UTF-8 using the subtitle encoding guide, then check it in the player your audience will actually open. The Bengali subtitle generator covers how to tell a shaping fault from an encoding one.

Because Malayalam builds words by agglutination and compounding, with no fixed limit on how long a word can get. Speakers routinely form words that have never been written down before, so the effective vocabulary is open-ended rather than a fixed list. Research on Malayalam speech recognition notes that this makes covering every wordform impractical, which is why drafts need a closer read than a language with a settled vocabulary.
Because one word can be longer than the whole line budget. Nothing can break a word across two lines, so the longest word in a cue decides the shortest that cue can be made. Where that single word already exceeds the limit, re-breaking is arithmetic with no solution and the answer has to come from the wording instead.
Rephrase rather than re-break. A long compound can usually be expressed as two shorter words, and that is an editorial change made where the caption text is still editable. Splitting the cue is the other option, but it changes timing, so do it somewhere you can check the result against the video.
Start with the compounds. A mistake buried inside one still looks like a real word, so it survives a quick read in a way obvious nonsense would not. After that, proper nouns, then any English spoken mid-sentence, choosing one treatment and holding it so the file does not read as though two people wrote it.
Sometimes, and it is worth telling apart from a transcription mistake. Every character can be correct in the file and still display wrongly if the player falls back to a font that cannot shape the script. Rule out encoding first by confirming UTF-8, then judge it on a phone in the app your viewers actually use.
Reviewed Malayalam captions export as SRT or VTT subtitle files, plain text, or a captioned video. Keep the subtitle file even when you ship a captioned video, since it is the version you can still correct. Open the caption generator.
Transcribe, check the long compounds and the overflowing cues, then export SRT, VTT, text, or a captioned video.
