If you have a low shutter speed and shaky movement for example going up and down, then you will have some vertical motion blur, you see? Since it follows the movement, it's fine. So you are saying Catalyst adds artifacts to the motion blur from a lower shutter speed regardless of IBIS being on or off? The person more knowlegable than you has spoken, and posted a video! Maybe you needed to crop so much for stability your video became very soft - 80% (20%crop) is very high. It is also relevant what crop you use, since the higher the crop the softer the video. No software update can deal with this.Īgain, you can claim you don't see any artifacts, but I can tell you I have seen them. No, the reason for the higher shutter speed is that motion blur leads to bad artifacts when using gyro stabilization in post, so you need to avoid motion blur. If no one beats me to it I'll post up a video when I have time to make a comparison. Hopefully someone more knowledgeable will be able to confirm as well. I will need to do more testing as I just discovered this today by accident. When using steady shot I can shoot at 1/60 and not get those vibrations, and I can still use catalyst browse to stabilize. It seemed to work just fine and I do not see any artifacts. I was surprised when I opened a video I had taken with IBIS on and it gave me the option to stabilize. What I understood when I purchased the a7C was that catalyst browse could NOT stabilize the video when steady shot (IBIS) had been enabled, and the reason for the higher shutter speed was because with steady shot off you will get shock/vibrations while walking if using 1/60 second. The camera does not matter the stabilization stabilization technology is the same across the newest Sony cameras. To prove I am not an armchair critic, here is my demo of gyro stabilization using Catalyst Browse and following all the rules: Content (subjects, or color or exposure) does not matter for this. I understand it is work to create and post videos, but if you really want to understand what is what, it can best be be done by showing what you get. So, let's see if you missed them or if Sony does not know what it is talking about. So if you are walking while shooting, using low shutter speeds and also have stabilization enabled in camera, you supposedly should be seeing some quite visible artifacts. Why don't you post your videos testing gyro stabilization? It does not help very much to just claim "It looked almost like a gimbal." The gyro stabilization works best, for example, at high shutter speeds allegedly. Would be very interesting to hear more input on this. Will probably require a more scientific A/B testing to see how well it is actually working with steady shot activated, but for me it seems to work very well. Much improved from the video with just steady shot alone. I did some walking panning shots of my car with steady shot on and stabilized in catalyst browse at 80% and it looked almost like a gimbal. ![]() I do like that you don't get as much of the vibration effect when walking with a slower shutter speed with steady shot on. ![]() Hard to tell if it works better with IBIS turned off, since the video is shakier to begin with. ![]() I tried catalyst browse stabilization with and without steady shot activated. My videos were all shot using an a7C in 4k 30p 100mbps. Yes I noticed this as well! Stabilization works in catalyst browse even with steady shot (IBIS) activated. ![]() the only thing I'd love to see is some sort of batch processing option since right now having to do each clip will slow down my work flow a good bit. Out of the 30+ clips I shot only one did not allow post stabilization processing and I can't figure out why either same lens same shooting condition.Īnyone figured out the exact requirement to make sure that gyro stabilization is enabled?Īlso when it does work the level of stabilization is great, approaching the level of stabilization I am accustom to see on the latest gopro camera minus the horizon leveling option. I tried using Catalyst Browse to do post stabilization and from what I have read you must disable IBIS in order for this to work however I noticed that at least for me Catalyst stabilization works even on clips with Steady shot enabled. I recently upgraded to the A7C from EOSM and I had been experimenting with various function on the A7C.
