Frequently Asked Questions

Why convert MOV to FLV?

FLV (Flash Video) is needed for legacy Flash-based platforms, older video players, and RTMP streaming workflows. While Flash is deprecated, many archival and enterprise systems still use FLV.

Does FLV support the high quality of MOV files?

FLV with H.264 encoding delivers good quality, though MOV files (especially ProRes) are often higher quality. Expect some quality reduction due to the compression change.

Is QuickTime MOV the same as MP4?

MOV and MP4 share similar codec support but use different container structures. MOV is Apple's proprietary container and is optimized for the Apple ecosystem.

How do I play the FLV file without Flash Player?

VLC Media Player, Windows Media Player with codecs, and many other modern players support FLV playback without requiring Adobe Flash Player.

Will the audio from my MOV file transfer to FLV?

Yes. FFmpeg transcodes both the video and audio streams. The audio is re-encoded as AAC in the FLV container.

Is there a file size limit?

Files up to 50MB are supported. For larger MOV files, compress or trim the video first before uploading to ChangeThisFile.

Is the MOV file deleted after conversion?

Yes, your uploaded MOV and the resulting FLV are both automatically removed from our servers after you download the converted file.

Can I convert MOV files exported from Final Cut Pro?

Yes. MOV files from Final Cut Pro, iMovie, or any QuickTime-compatible export are supported. Make sure the file is within the 50MB size limit.

Does the FLV support the same frame rate as the MOV?

Yes, FFmpeg preserves the source frame rate during conversion unless the source rate exceeds FLV container limits.

Is this tool free to use?

Yes. ChangeThisFile is completely free, with no accounts, subscriptions, or hidden fees.
