Accuracy and scope
Server processing. Temporary results expire after 15 minutes. Maximum 2 MB UTF-8 input and 20,000 cues. Styling, positions and karaoke effects may be lost in simpler formats. SUB means text MicroDVD subtitles, not VobSub bitmap files. Set the correct frame rate for MicroDVD. TTML/SAMI export covers supported cue text and timing, not every layout feature. Timing scale is applied before the offset. Adjustments that move cues before zero are rejected. Plain text removes inline formatting; richer positioning may be lost during export.
Is my data uploaded?
This tool uploads your supplied input to the FeuTex processing server. Input and output files are temporary and expire after 15 minutes.
Correct timing while converting
Use a positive offset to show captions later, or a negative offset to show them earlier. Timing scale stretches all timestamps: 100% keeps timing unchanged, 104.27% lengthens it. Scaling happens before the offset. Enable plain text to remove inline style tags. Adjustments that would place a cue before zero are rejected rather than silently clipping captions.
