| p.1 #1 · p.1 #1 · Video recording cross-country races with a bicycle and Sony a7S3 or a1 with Zeiss 55 f1.8 | |
I have been recording high school track and field events for the last two years using two Sony a7S3, a6500 and RX10IV. This year, I wanted to cover the cross-country races (3 miles) at least the front runner.
I tested with a GoPro mounted on a bicycle recording 4k60 but the image quality sucks especially when you crop in from the 15mm wide angle fisheye lens.
For better image quality I used the Sony a7S3 in 4k60 with the Zeiss 55 f1.8.
The requirement is that the footage must be smooth and higher quality than the GoPro videos.
What I learned:
1. You need a strong gimbal, like the DJI Ronin-m. The other consumer gimbals will break (I broke two).
2. You need vibration isolators (the wire type) as well as rubber dampers where the vibration isolator is mounted to the bike.
3. You can use the app "Monitor" to view what the a7S3 or the a1 is recording.
4. And you must use either the Sony Catalyst Browse (free) or GyroFlow (free).
Sony Catalyst is very smooth but they do not output anything higher than 4K and the codec is standard MP4 (10X compression). Sony Catalyst takes 10 times actual footage time to render (i.e., 10 minutes equal 100 minutes of rendering on an M1Max 16 inch). Gyroflow takes 2X actual footage time to render and in ProRes HQ at 6K or 8K. But Gyroflow isn't as smooth as Sony Catalyst. My fix for Gyroflow is to use Final Cut Pro X stabilization as "inertia cam" to smooth it out.
Comparison between Sony Catalyst vs just gimbal alone here with Sony a7S3 + 55mm cropped in 2X:
Comparison between Sony Catalyst vs Gyroflow on sony A1 and 55m recording in 8K30.
