Key features
Play FLV videos in QuickTime
The program converts FLV to MOV so the files play on QuickTime player.
Convert many files at once, faster
It supports multithreading and batch processing, so several conversions can run at the same time. It can also process each conversion across multiple CPU cores.
Turn photos into a MOV video
You can make pictures in JPG, PNG, BMP and GIF formats into a MOV video.
Shape the output file
You can split a large file by time or size, and extract a segment by setting a start time and duration. A built-in Bitrate Calculator works out the video bit rate for a target size. You can also adjust video codec, video size, bit rate, frame rate, audio codec and channels.
Run it in the background and let it shut down the PC
The converter can run in the background while you use other applications. Afterwards it can quit, shut down, hibernate or put the computer on standby. You can also preview a source file and take a snapshot during the preview.
Who it's for
It suits you if you have a pile of downloaded FLV videos and want them in QuickTime-friendly MOV. It is a single-purpose tool, so it isn't aimed at people who need many output formats.
