50 MB total input; at most five files. Video/GIF: 120 seconds and 1920×1080 maximum; audio: 300 seconds. GIF reversal: at most 10 seconds and one megapixel. A 31 MB engine loads from PasteZap on first use. Processing has a two-minute time limit per operation. Output limit: 50 MB; re-encoding can reduce quality.
Join audio files in the displayed order with standardized stereo resampling. Files are never sent to a conversion service. The single-thread FFmpeg engine runs in a local worker and can be cancelled. Numeric trimming, cropping and file-order controls are used. Video merging exports silent 640×360 clips; audio replacement uses the shorter duration. Center cancellation is not AI stem separation. Watermarks use the bundled Liberation Sans font; complex-script shaping and colored emoji are not guaranteed. Loudness normalization uses FFmpeg loudnorm, but very short clips may not reach the target precisely.
