DivX is one of the popular video compression codecs. You can configure its parameters through the interface of the program used to compress the movie. To save time when post-processing files, a set of presets can be saved as a preset.
Necessary
- - DivX codec;
- - video;
- - Canopus ProCoder program.
Instructions
Step 1
You can use Canopus ProCoder to compress video using the DivX codec. Load the file for processing by clicking on the Add button in the Source tab.
Step 2
Switch to the Target tab to set the desired compression parameters. If you do not yet have a file to be processed, you can go to the compression settings after opening the program.
Step 3
Use the Add button to bring up a list of available formats and presets. With the System group highlighted, select the DivX Target option there. To access the expanded codec settings, click on the Advanced button.
Step 4
You can select one of the profiles from the Profiles drop-down list to get a file suitable for playback on a home theater or handheld device. If required, you can change the parameters included in the profile to your liking.
Step 5
Specify the frame size and aspect ratio in the Width, Height and Aspect Ratio fields. For correct playback of DivX-processed video, the height and width of the frame must be multiples of sixteen. If you are not going to change the original frame size, set these fields to values taken from similar fields in the Source tab.
Step 6
Select the number of passes when encoding video from the Variable Bitrate list. The 1-pass mode should be used if you need to reduce the processing time of a file. The 1-pass quality based mode will allow you to control the compression rate of frames with the same one-pass coding. To do this, you will need to adjust the Quantizer parameter, telling the program how much it can ignore image details when compressed.
Step 7
By choosing the multi-pass mode, you will increase the video processing time, but give the program the ability to pre-analyze the file in the first pass, which will allow you to get a smaller movie while maintaining quality.
Step 8
The Video Quality setting allows you to control the image quality and processing speed. The Minimum quality option will allow you to quickly compress the file, which will suffer the quality, the High quality option will require more processing time, but the image will suffer less during compression.
Step 9
Adjust the Max keyframe interval value, which specifies the number of intermediate frames between two key frames. If the file being processed consists of a large number of still scenes, you can increase the value of this parameter. To properly compress dynamic video, you need to decrease this value.
Step 10
If the file you are processing contains scenes with a small amount of light, you can use the Use Psychvisual Enhancements option by checking the corresponding checkbox. When compressing the image, this will allow the program to ignore the details in the shaded areas of the image, as a result of which the weight of the final file will be reduced.
Step 11
To save the settings as a preset, click on the Save Preset button. If the program has already loaded a file for processing, start the video compression by going to the Convert tab.
