Canon XH-A1 - Time Remapping - Slow Motion
5 months ago
Added: 05 February 2008
Hey everyone. This video just tests how I can take footage with the Canon XH-A1, import and time-remap it in After Effects, and edit it in Premiere Pro. Hope you like!
Process: The video footage was shot in 50i, then imported into After Effects so that the upper and lower fields of the interlaced footage could be seperated to become individual, whole frames. The footage was then time-remapped with a motion detector called 'Pixel Motion' in After Effects. The footage was exported and edited in Premiere Pro, with the audio edited in Audition. The footage has remained in HD every step of the editing process, until it was exported for YouTube and Vimeo.
A flaw that time-remapping has is the occasional 'ghosting' that can appear, as seen around my arms. This is caused by fast movement which the 'Pixel Motion' detector cannot compensate 'intermediate frames' for, and tends to 'frame blend' sections of the image for those instances.

My question is what process did you go through to deinterlace the frames to make them whole. I'm just having trouble getting mine as clean as yours. Thanks - Matt
I used Adobe's "After Effects" programme to create whole-frames. If you're familiar with After Effects - right-click your video file in your project >> go "Interpret Footage" >> "Main" >> and make sure "Upper Field First" is selected under "Fields and Pulldown".
From there you can make your video speed 50% of realtime, making one whole frame appear every 1/30th of a second. Your resulting video is 1/2-speed, and deinterlaced. I'm not exactly sure how things go with the NTSC format when it comes to time-remapping or deinterlacing, but that would be the way I'd deinterlace NTSC footage.
Hope it helps!

Could you anybody help me?
awesome slowmotion.
And nice ending! :)
