Welcome to Replay Media Catcher for Mac

Replay Media Catcher for Mac is the easiest, most advanced streaming media recording technology ever created.  Once monitoring, Replay Media Catcher will save video and audio files from thousands of web sites as they play on your Mac.  These files can be transferred to other devices like your iPod, iPhone, iPad, Apple TV or burned to a CD or DVD disc, or used in other applications like iMovie.

Using Replay Media Catcher for Mac is as easy as clicking the monitoring switch from monitor switch in off positionto monitor switch in on position. Replay Media Catcher for Mac will then monitor your incoming network connections for media. As you surf the internet with your favorite browser, when media is identified, it will be saved. Here's how it works. Replay Media Catcher locates the web address of the media file, reconnects to the host server, and makes an exact copy of the file on your Mac.  Typically, this download process is much faster than actually playing the file.  Replay Media Catcher also can make multiple simultaneous connections to further speed up the capture process.  For example, download music from Pandora and videos from YouTube at the same time. Once the download process starts, you can close the video or audio player, and the file will continue to be captured.

Note: Some web sites use encryption when streaming video. Replay Media Catcher cannot download these encrypted streams.

Overview and Use

How to Start Recording:

When you open Replay Media Catcher you will be asked if you would like to start monitoring the network activity on your Mac for recording:

Replay Media Catcher also features a URL downloader bar, where you manually enter the URL address of the video file you want to download and press the GET button or hit enter/return.

Converting Video and Audio

Replay Media Catcherr can automatically convert captured media files to other formats. The default setting is Default Conversion.  This is best if you would like everything that you download to be easily playable on your Mac. For example, it converts downloaded FLV’s to .mov files that play perfectly in Quicktime. Or simply pick a conversion type that is specific to the device that you will be playing the media on.

You can also convert a file after it has been captured. Here’s how:

  • Change the output format in the Conversion drop-down list at the bottom of the main window.
  • Right-click the file to make the options menu appear.
  • Select Convert from the pop-up menu.
  • Notice you can also choose to convert your selection to an audio file right from the same right-click menu.

Add Recordings to iTunes

The Add to iTunes option becomes available if you have selected an iTunes compatible device format in the conversion drop-down.  For example, if you have selected iPad and add to iTunes, captured files will be converted to the best format for your iPad, and sent directly to your iTunes library. 

Now just sync your iPad! This also works great for Apple TV. Send those converted files to iTunes, and enjoy the show on your TV.

How to Play Captured Files

Once a file has been saved and converted, it is easy to play:

  • Right-click the file for the options menu to appear.
  • Select Play. Replay Media Catcher will open the file in the default player for that file type.

Hint: Use Preferences, Downloads to see or change folder where your saved recordings reside.

This dialog shows the HTTP content types that Replay Media Catcher recognizes, and what extension it adds to the saved file. You will only need to change this if you are technically savvy, and a new media type is discovered.

  • Ignore Shockwave Flash: Leave this checked if you want Replay Media Catcher to ignore SWF files like flash banner ads
  • Max number of segments: When Replay Media Catcher begins a download, it asks for different parts of the media simultaneously. This effectively speeds up the downloading process. If you find that too much network bandwidth is being used, reduce this number. Increasing this to more than 5 segments won’t speed up downloads though.
  • Minimum Segment size: Lets you determine how big the smallest segments to download should be. For example, if this is set to 300 Kb, and the size of the video to be downloaded is 300 Kb, then a single request will be used. For smaller media files, downloading with a single request is faster than using multiple segments.
