To add a video file for encoding, navigate to your Bookmarks, select a file and drag it onto the Job Batch. The file I’m encoding is called Fish02.mov and is a 720 x 480 DV QuickTime Source.
Step 2
COPY A PRESET IN EPISODE
Now, you can copy your preset for 3GPP encoding. Inside the By Workflow Templates navigate to Mobile/UMTS (3G)/. Open the Streaming folder inside UMTS 3GPP. Control-click the 3gp_MPEG4_AAC_128kbit_qcif_stream preset and choose duplicate from the contextual menu. Click once where the text is displayed on the copied preset. Once you select your preset, click again where the text is displayed to edit the name. Label your new preset 3gp_240_220k and click Enter.
Step 3
Now, let’s adjust your 3GPP preset. Double-click the 3gp_240_220k preset. At the first tab under 3GP Version, choose 3GPP v 5 from the Pop-up menu. Under Hint, select Prepare for Streaming. This is mandatory for real-time streaming on QuickTime Streaming Server. Next, move to the Video tab. Adjust the Average datarate setting to 185 kb/s, and deselect Simple Profile Level 0. Place the Frame skip probability slider to 0.25. This will reduce dropped frames. Move the VBV buffer size to 1.0 second to produce more of a CBR encode. Make sure 2-pass encoding is selected along with Natural and Forced Keyframes under Keyframe control. Adjust your Keyframe distance to 60 frames and close the MPEG-4 filter settings. Open the Frame Rate filter. Select Fixed Framerate and adjust your Framerate preset to Automatic, selecting 15 fps for the frame rate. Close the filter and open the Deinterlace filter. Make sure Complete Deinterlace is selected under Deinterlace Type and close the Deinterlace filter. Under the Resize Filter choose 240 x 180 from the Pixel Pop-up menu. No cropping is needed as there’s no black banding.
You can add a contrast boost of 15 in the Contrast filter and add a setting of 15 for Saturation in the HSV Levels filter. This might be beneficial, depending on your source.
Next, move to the Audio tab. Choose 32 kb/s AAC Low Complexity, Mono and a Sample Rate of 16 kHz. With all of your adjustments made, click the Save button. Now that your settings are saved, drag the 3gp_240_220k preset you created onto your video source in the Batch. Click the Start Encoding button.
