Frequently Asked Questions

Will I lose video quality when converting from FLV to MP4?

Not with our converter. By using High-Efficiency Video Coding (HEVC) and bit-perfect transcoding, we ensure that your output file maintains the original resolution, frame rate, and clarity of the source FLV without introducing compression artifacts.

Does this converter fix the 'Audio-Sync' issues common in FLV files?

Yes. Legacy FLV files often use Variable Frame Rates (VFR) which cause audio to drift. Our engine automatically normalizes these to a Constant Frame Rate (CFR) during conversion, ensuring your audio and video stay perfectly in sync for the entire duration.

Can I convert FLV files into a format I can edit in Premiere Pro or Final Cut?

Absolutely. You can convert your FLVs directly into ProRes or high-bitrate MOV files. These are professional, 'edit-ready' formats that eliminate the playback lag and import errors often found when trying to use raw FLV footage in modern NLEs.

Is batch conversion supported for large video archives?

Yes. Our tool is built for industrial-scale workflows. You can drag and drop thousands of FLV files at once. Our Multi-Core Hardware Acceleration leverages your GPU to process multiple files simultaneously, finishing hours of work in minutes.

Will the converted files play on my iPhone, iPad, or Apple TV?

Guaranteed. We provide optimized device presets. Simply select your device from the menu, and the software will automatically choose the best settings (h.264/h.265) to ensure native playback across the entire Apple ecosystem.

Can I extract just the audio from an FLV file?

Yes. If you have a lecture or a music video in FLV format, you can choose to export only the audio. We support high-fidelity extraction to MP3, AAC, or lossless AIFF/WAV formats.

Do I need to be a tech expert to use this?

Not at all. While the backend is professional-grade, the interface is designed for a 'One-Click' workflow. Just drag your file in, select a preset, and hit convert. The software handles the complex codec settings for you.

Is there a file size limit for conversion?

Absolutely. Our industrial-grade engine is built for scale. You can batch-convert up to 100 FLV files simultaneously to save hours of manual work. To ensure peak performance and stability during the transcoding process, we support individual file sizes up to 2GB—perfect for long-form webcasts, legacy archives, and high-bitrate video recovery.
