No, converting 3GP to SRT does not cause additional quality loss — SRT uses lossless compression. However, any artifacts already present in the original 3GP file will persist in the SRT output.
SRT files are typically 2-5x larger than equivalent 3GP files because SRT preserves all pixel data. This is expected and necessary for lossless quality.
