Studio times captions from your voice, so they stay in sync after every cut.
The same amount throughout happens when an intro was added or removed: move everything by that many seconds. Right, then wrong happens when a scene or an advert was cut in the middle: shift from the first caption after the cut. Drifting, fine at the start and several seconds out by the end, means the video's speed changed: use the stretch option.
Play the video and note when a clearly spoken line is said. Compare with that caption's start time. If the line is spoken at 0:12 and its caption says 0:14, the captions are 2 seconds late.
Type the time the first caption should start and the time the last one should start. Every caption in between is moved in proportion, which corrects a speed difference and an offset together.
A caption that would end before the start of the video is removed, and one that would start before it is set to start at 0:00. The tool tells you how many.
Yes. The amount takes decimals, such as 0.35.
The frame rate converter applies a known speed change, such as 23.976 to 25 frames a second. The stretch option here works from two times you observed, whatever the cause.
Fix caption text and timing line by line, with your video playing alongside.
Fix captions that drift further out of sync as a video plays, after a frame rate change.
Check a caption file for lines that are too long, too fast, too short or overlapping, and fix them.
Burn an SRT or WebVTT caption file into a video so the captions show on every platform.
Upload the raw recording. Studio cuts the ums, retakes and long pauses, adds captions and makes short clips. 30 free minutes, no card.
