GoToWebinar and GoToMeeting online meeting and screen capture/sharing software uses a proprietary codec in order to reduce file sizes. Due to this, we are unable to directly support files containing the GoToMeeting Codec. This article will detail either how to re-encode the file, or change the type of file GoToMeeting/GoToWebinar produces before you begin.
- I haven’t had my meeting/webinar yet
- I’ve completed my meeting/webinar already
- Using Expression Encoder 4 on Windows
In order to produce a standard Windows Media file (.wmv) – The host of the webinar/meeting needs to select the “Convert to Windows Media Player file” option in the Recording references dialog box before the webinar is recorded. To access this option, right-click the GoToMeeting/GoToWebinar system tray icon, select Preferences and then Recording. Or, if you have a Webinar open, click File on the top of the control panel, select Preferences and then Recording. Then select “Convert to Windows Media Player file.” GoToMeeting/GoToWebinar will convert the recorded meeting into a standard Windows Media file (.wmv) after the meeting is over to avoid slowing down the computer during the meeting.
We have good news and bad news for you. Good news: You can re-encode the file! Bad news: The only method we’ve found so far is Windows-only.
To re-encode, use the free Expression Encoder 4 from Microsoft (During the install, it will ask for a key--The encoder will be limited in functionality, but will still perform as we need it to, so there is no need to enter one in this case). If you don’t have GoToMeeting set up on your machine, you might also need the GoToMeeting Codec.
- Open Expression Encoder 4, and choose “Transcoding Project”
- Import your video file into Expression Encoder 4 either by dragging and dropping the file into the program window or by clicking the “Import” button
- Adjust the encoding settings
- Output format should be “Windows Media”
- Video should be set to “VC-1 Main”
- Audio should be set to “WMA”
- You’ll want to set your bitrate based on your resolution, but it should be safe to use 2000 kbps (or higher)
- For size, you will obtain best results by selecting 1280 for width and 720 for height, which will provide you with a 720p file.
- The aspect ratio should be set to either “16:9” or “Source if the file already is already in a widescreen format. For resize mode, choose letterbox. This will set the encode to not stretch the webinar/meeting footage if it is not widescreen (It will result in black bars on the side, if necessary)
- For Audio, “CBR-1” Pass is fine, but setting the bitrate to 128kbps is recommended. The rest of the settings should be left as defaults.
- Click on the Encode Button. The Resulting File can be found in the "My Documents" directory. From there, the software places the file a few folders deep: \Expression\Expression Encoder\Output\ - The actual .wmv file is located in a folder named with your Computer's name and the date and time of the job. You can then Upload to Viddler.
