The following technical constraints require special attention to ensure optimal use:
- platform-specific: Currently, only public YouTube videos are supported, platforms such as Vimeo and private videos cannot be processed.
- Duration impact::
- Video up to 5 minutes: subtitle generation approx. 30 seconds, dubbing approx. 2 minutes
- 30-minute video: processing time may be extended to 15-20 minutes
- Content requirements::
- Recommended to use a clear audio source with background noise <40dB
- Videos with a lot of jargon are recommended to provide a glossary of terms first
- Speech rate over 180 words/minute may affect recognition accuracy
- format compatibility::
- Output subtitle supports SRT/VTT/TXT formats.
- Voiceover audio is currently available in MP3 format only.
Optimization Suggestion: For long videos, you can first process 2 minutes of samples to test the effect, and then submit the complete video after confirming that there is no error.
