The batch panel shows:

Overall batch progress (percentage)
Individual file status
Estimated completion time
Credits consumed vs estimated
Error logs per file

Optimization Strategies

File Organization

Group files by project or topic
Use consistent naming conventions
Separate by language when necessary
Sort by priority

Recommended Settings

Use AssemblyAI for best cost-effectiveness (15 cycles/min)
Enable speaker identification only when needed
Choose the correct language for best accuracy
Set up webhooks for completion notifications

Check your credit balance before starting a large batch. The system calculates the estimated cost before starting, but individual transcriptions in progress cannot be canceled.

Troubleshooting

Some files failed in the batch

Possible causes: Unsupported format, corrupted file, insufficient credits.

Solutions: Check the formats of the failed files, try reprocessing individually, confirm your credit balance.

Processing is very slow

Possible causes: Many large files, peak hours, parallel processing limit.

Solutions: Split into smaller batches, submit during off-peak hours, consider upgrading your plan for more parallel slots.

Inconsistent results between files

Possible causes: Variable audio quality, different languages, incorrect settings.

Solutions: Normalize the audio before uploading, configure language per file when needed, review batch settings.

For very large batches (more than 50 files), split them into sub-batches of 20-30 files. This makes monitoring easier and allows you to identify issues more quickly.
