No-Crash Guarantee: How We Ensure Stability
12+ AI models with intelligent fallback processing
Intelligent Fallback System
When you upload a large video, our system doesn't rely on a single AI model. We use a cascading fallback system with 12+ different AI transcription and translation models:
- RunPod Modern (8x faster): Primary model for quick processing
- Assembly AI: High accuracy backup for complex audio
- Deepgram Nova-2: Fastest processing for urgent jobs
- Legacy Models: Additional fallbacks ensure 99.2% success rate
Result: If one model fails or times out on your 2GB file, the system automatically retries with a different model. You never see the error - it just works.
Progress Tracking & Transparency
Unlike other tools that leave you wondering if your large file is processing or crashed, our system provides real-time status updates:
- Upload Progress: See real-time upload % for your 1-2GB file
- Processing Stages: Track transcription → translation → subtitle generation
- Email Notifications: Receive alerts when processing completes
- Dashboard Access: Check job status anytime from your account
Confidence: You always know your file is processing, not stuck or crashed. Average large file processing: 15-35 minutes depending on length.

Technical Specifications for Large Files
File Size Calculator: What is 2GB?
Video file size depends on resolution, bitrate, and length. Here's what fits in 2GB:
1080p HD Video (8 Mbps)
Approximately 33 minutes of footage
Typical YouTube/Vimeo HD quality
720p HD Video (5 Mbps)
Approximately 53 minutes of footage
Standard HD streaming quality
4K UHD Video (45 Mbps)
Approximately 5.9 minutes of footage
High bitrate 4K recording
Compressed 1080p (3 Mbps)
Approximately 88 minutes (feature film)
Efficient H.264 encoding
Pro Tip: Most feature-length movies are encoded at 3-5 Mbps for streaming, resulting in 1-1.5GB files for 90-120 minutes. This fits comfortably within our 2GB limit. Use HandBrake to compress 4K footage to 1080p if needed.
How to Compress Videos Over 2GB
If your video exceeds 2GB, you can compress it without significant quality loss using free tools:
- 1.
HandBrake (Free & Open Source)
Download from handbrake.fr. Use "Fast 1080p30" preset. Reduces 4K to 1080p with minimal quality loss. A 4GB 4K video becomes ~1.2GB 1080p.
- 2.
Adobe Media Encoder (Professional)
If you have Adobe Creative Cloud, use H.264 preset with target bitrate 3-5 Mbps. Balances quality and file size perfectly.
- 3.
FFmpeg (Command Line)
ffmpeg -i input.mp4 -vcodec h264 -crf 23 -preset medium -acodec aac output.mp4
Reduces file size by 40-60% while maintaining visual quality.

Large Video File Translation FAQs
What if my file is larger than 2GB?
If your video exceeds 2GB, we recommend using a video compression tool like HandBrake or Adobe Media Encoder to reduce file size while maintaining quality. Most 1080p videos can be compressed to under 2GB without noticeable quality loss. Alternatively, you can split your video into segments, translate each separately, and combine the subtitle files. Our support team can guide you through the compression process if needed.
Why do other subtitle tools have file size limits?
Most free subtitle generators use basic cloud infrastructure that cannot handle large file processing. They impose 250MB-500MB limits because larger files crash their servers or take too long to process. We use enterprise-grade AWS infrastructure with dedicated video processing pipelines designed specifically for large files up to 2GB, ensuring stable processing even for feature-length movies and long conference recordings.
How long does it take to process a large file (1-2GB)?
Processing time depends on video length, not file size. A 1.5GB file with 90 minutes of content typically takes 15-20 minutes. A 2GB file with 3 hours of content may take 25-35 minutes. Our system processes videos in parallel chunks, so even long videos complete faster than traditional sequential processing. You'll receive an email notification when your subtitles are ready.
What video quality do you support for large files?
We support all common video resolutions including 720p HD, 1080p Full HD, and 4K UHD. Higher resolution files are naturally larger - a 4K video will be bigger than 1080p for the same duration. Our AI transcription works on the audio track, so video resolution doesn't affect subtitle accuracy. The 2GB limit is based on total file size, regardless of resolution.
Will my video quality degrade during processing?
No. We extract only the audio track for transcription and translation. Your original video file remains untouched. If you choose hardcoded subtitles (subtitles burned into the video), we use high-quality encoding settings to preserve your original video quality. The output video will be similar in size and quality to your input file.
What happens if processing fails for my large file?
Our system uses intelligent fallback processing with 12+ AI models. If one model encounters an issue, the system automatically retries with a different model. We have a 99.2% success rate for large files. If processing fails (extremely rare), you receive a full automatic refund within 24 hours. No questions asked. Our money-back guarantee ensures zero risk when uploading large files.
Can I upload multiple large files at once?
Yes! Each video is processed independently as a separate $8 transaction. You can upload multiple large files simultaneously, and our system will process them in parallel. This is perfect if you have multiple conference recordings, training videos, or documentary episodes to translate. Each file gets its own set of subtitles (SRT, VTT, and optional hardcoded video).
