In the format box you can select Quicktime Movie or MPEG-4. MPEG-4 is a good proxy format and is adequate for most uses particularly when generating proxies for the web client.

Select MPEG-4 and press settings, this brings up the MPEG-4 Export Setting box


You can then configure the video, audio options. If these proxies are to be used with the webclient , click enable streaming in the streaming settings.

Click OK.

If you need to generate a proxy file in a specific format, for example if you are using the proxy files to edit with, then you will need to use the Quicktime Movie Drop Drown box.


Select the Customise. This reveals the default Quicktime Movie Settings, here you can select the specific codec required by pressing the settings button.


The available codecs list is restricted to the codecs installed on the machine. You may need to load additional codecs such as Pro res on the CatDV client machine in order for quicktime to make it available for selection. Make sure Prepare for Internet Streaming is selected if you plan to use proxies with the web browser.


H264 is selected as the proxy format. Click OK on the compression settings, then click OK on the Movie settings to return back to the Quicktime Proxy Settings Menu.


The options on the Quicktime Proxy Settings Menu can be selected for both MPEG-4 Format and Quicktime Format options.

You can set the scale of the proxy not to exceed the size selected in the drop down box. For web proxies we recommend to keep the size small (320 x 240) if being used as NLE proxies then a higher size is such as (1280 x 720). You could also add custom sizes by selecting custom and entering the scale manually.

Click the Add timecode track option if you wish create a timecode track that is encoded into the file, this is useful if you use the proxy files with your NLE system. Any proxy file timecode will match the timecode from the original media.

There are 3 burn in options, you can burn in the timecode and tape or file name  information of the original media. You can also burn in a watermark file such as a company logo or copyright watermark from a transparent png or jpg file. Use the choose box to navigate to the .png or .jpg.

Once you are happy with your options press OK. This will now be the settings used when selecting Media/Build Proxies Movies.
