Review: proDAD ReSpeedr

In Figure 2 (below), I’ve taken my shot and slowed it down to 34.8%. I did this via the Duration option since I have a spot on my timeline that is 10 seconds long. I generated a 34.8% slow motion calculation. I also clicked on the Optical-Flow option to create those extra frames. On the timeline, you can see the small Orange dots indicating Optical-Flow is being used. The Target Media tab shows the new duration information of my clip.

Exporting a Slowed-Down Clip

Now that we have our slow motion set up it is time to export. Along the top of the ReSpeedr UI you’ll find an Export Optimized Media tab for rendering your output, as shown in Figure 3 (below).

The Red arrow points to 2 small icons, a filmstrip and a QuickTime logo. If you click on the filmstrip, your export will be an MP4 file. If you click on the QuickTime, icon your export will be a QuickTime file. Depending on your edit system, you may want to select one over the other. The bitrate of your rendered file is determined by the compression settings option just to the left of the Filmstrip and QuickTime icons.

The Yellow arrow that you can see in Figure 3 represents the Render Quality. If you select the Render Quality option, a dialog appears, as shown in Figure 4 (below). By default, the Optical-Flow option is not turned up all the way. I checked all five of the stars since I want my slow motion to be the best possible. This will make your final renders take longer since processing is increased. You can also turn on hardware acceleration if you have the proper graphics card.
