Will my subtitles look different after converting to ASS?

No. The conversion does not invent styling — it writes a single default style and puts every line under it, so playback looks essentially the same as the SRT did. What changes is that the file now has a style block you can edit, which SRT never had.

Why would I convert SRT to ASS in the first place?

To gain control SRT cannot give you: a specific font and size, a colour, an outline thick enough to stay readable over bright scenes, or a line moved to the top of the frame so it does not cover a caption. ASS is also the working format of editors like Aegisub.

Can I open the result in Aegisub?

Yes, and that is the usual reason to convert. Aegisub works natively in ASS, so afterwards you can restyle every line, reposition cues, add karaoke timing or run the timing post-processor. Saving from Aegisub keeps the file in ASS.

What resolution does the generated file assume?

The file carries PlayResX and PlayResY fields that tell the player which coordinate space the styling was designed for. Sensible defaults are written for you; if you plan to position anything precisely, set those two fields to your video resolution in the editor first.

Do the timings change?

They are rewritten into the ASS notation — hours become a single digit and fractions go to hundredths, so 00:00:04,500 reads as 0:00:04.50 — but the moments themselves are identical. Nothing is shifted, and that rounding is a formatting difference, not a retiming.

Will italics from the SRT carry over?

Yes. The i and b tags become the ASS override tags for italic and bold, so emphasis is preserved rather than dropped. Everything else in an SRT is plain text, so there is nothing further that needs translating.

Should I convert to ASS just to play the file?

Usually not. If the goal is simply to watch the video, SRT is the more compatible choice and ASS gains you nothing on a TV or set-top box. Convert when you intend to style or edit the subtitles, not when you only need them to display.
