Creating a Higher Frame Rate Composer Video

Jesse Haworth

This article walks through the steps needed to generate a higher frame rate video of a Composer animation.

Currently, videos that are created by using the Video Workshop within Composer are limited to 30 frames per second. If a higher frame rate is required, images that are generated by using the Composer High Resolution Image Workshop can be stitched together via third party software. 

High Resolution Image Workshop

As shown in the image below, in order to output enough images to create a video, the "Multiple" tab of the High Resolution Image Workshop will need to be accessed.

 

 

In this tab, selecting "Animation" will allow the number of outputted images per second to be specified.

For this example, 60 images per second will be created for 10 seconds of animation, which will eventually be stitched together to form a 10 second video with 60 frames per second.

Resolution and anti-aliasing settings can also be specified within the High Resolution Image Workshop. Once all desired options have been set, clicking on "Save As..." within this Workshop and selecting a destination folder will begin the process of creating the indicated number of images.

It is recommended that these images be saved in their own dedicated folder, as a high number of images could potentially be created, based on images per second and animation length.

Stitching Together Composer Images

Once the full number of images has been generated, they can be compiled together by third party software in order to form a video. For the steps shown below, the free software VirtualDubMod will be used. However, any software with the capability to stitch together images can be used. Some examples include QuickTime Pro, Adobe Premiere, and Sony Vegas.

VirtualDubMod can be downloaded by clicking on this link. Please note that Hawk Ridge Systems does not provide support for any third party program.

After downloading and opening VirtualDubMod, follow these steps to stitch together the previously created images.

1. Open the "Video" menu, and select "Frame Rate".

 

 

2. Within the "Video frame rate control" menu, select the "Change to" option, indicate the desired frame rate, and select "OK".

 

 

As a note, the number of frames per second that is typed into the "Change to" field will need to match the number of images per second that was previously creating using the Composer High Resolution Image Workshop. 

3. Select File > Open video file.

4. Navigate to the folder where the images were saved, and open the first image of the sequence. For this particular example, this would be "jig saw_anim0.jpg", as shown below.

 

 

5. Once this image has been opened, select File > Save As. By opening only the first image, VirtualDubMod can automatically stitch together the remaining images in the correct sequence. 

6. In the "Save As" window, it is possible to change the compression codec that is used before creating the video. By default, VirtualDubMod does not compress video files, which can result in extremely large file sizes. However, as is the case in Composer, VirtualDubMod can use the Xvid MPEG-4 Codec to compress videos into a manageable file size. The Xvid codec can be downloaded by navigating here.

 

 

The image above shows an example of changing the compression codec to Xvid MPEG-4.

7. After changing the compression options and naming the file, select "Save", which will begin the image compilation process.

By following these steps, a video with a frame rate higher than 30 can be created.
