General guidelines
Caption frames within files intended for the import service should conform to a maximum of 32 characters per line and a maximum of 2 lines per frame. Please see examples below of caption files that are supported by the 3Play Media Caption Imports process. If you have files that do not conform to these standards, please contact your account manager to inquire about support for your caption library. We may be able to help!

The import service supports the following formats:
- SRT
- SBV
- VTT

If you would like to import a different format, please contact your account manager first.
Visual Examples of Supported Formats
SRT
SRT files should have consecutive frame number to start each frame, timestamps that are separated by a two-hash arrow (“-->”), and a space between frames.
1
00:00:00,000 --> 00:00:04,440
These are caption frames
from a sample file.
2
00:00:04,440 --> 00:00:06,570
They're timed well and
spelled wonderfully.
3
00:00:06,570 --> 00:00:08,540
Plus, it's rather short,
so examples are concise!
WebVTT
WebVTT is similar to SRT, though the format does support additional information such as frame placement.
1
00:00:00.000 --> 00:00:04.440 align:middle line:90%
These are caption frames
from a sample file.
2
00:00:04.440 --> 00:00:06.570 align:middle line:90%

3
00:00:06.570 --> 00:00:08.540 align:middle line:90%
