This of course comes at expense of detailed backgrounds. To defeat rolling shutter artifacts, shallow depths-of-field for such follows also help to bury skewed uprights like treetrunks and utility poles. The background then blurs and the judder artifact is not as noticeable. It can be dealt with by ND-ing down to enable a wider iris for a shallow depth-of-field when pan following or tracking a subject like a moving car, a horserider or somebody running, travelling alongside and being kept steady in the frame. I've now watched the video i uploaded in a different monitor, and it looks slightly better.Īs others have commented, the judder artifact is a product of too last a pan or tilt for the 24P or 25P frame rate. that it is a physical cinematography issue rather than a "problem", but he also said that this issue will not happen if i will "shoot in SDI".ĭoes it makes any sense to you guys? what did he mean by that? is it possible to shoot that way with the blackmagic pocket cinema 6k? I've consulted with a cinematographer that was saying pretty much the same as you guys. I also compared the current test videos to clips from other projects i made in last 6 months, and it seems to me that it getting worse. it's not the original camera footage, but i assure you that the raw file looks just the same(its size is 9 GB so.) I tried to apply it in the next test video, which shows a very slow pan movement. I've read it and i'm your it will be useful in the future. I cannot access your second clip, something with the permissions went wrong. There are rules for tilt / pan speed for a reason. That's the way it has been since the analog film days. Lower frame rates like 24fps will always judder if you are tilting / panning too fast. The next thing is you cannot expect a clip shot in 24fps or 25fps playing back smoothly on a computer monitor which normally uses 60 Hz. That can be one source of stuttering - if there is a mismatch between shot fps and Resolve project fps. I asked specifically for an original clip.ĭespite you said it was shot in 24p the meta data of the rendered out clip says 25p.
Your first clip is NOT directly out of the camera. Or am I wrong and my specific camera has an issue? I guess that the stuttering is simply the image the BMPCC can provide? the stuttering disappears to some extent if I shoot with more FPS, but if I get to 30 and higher FPS, the image comes out too crispy. I've tested almost every FPS/Shutter combination.
It has extreme movement, since it's a test video concerning the issue in topic. This one was shot in 25 fps/50 shutter speed. its noticeable mainly if you concentrate on the dude's hand. You can see that even though the movement is quiet slow, the image is still stuttering.
This video was shot in 24 fps/180 shutter angle. the image is flat out stuttering whenever you do a fast movement. Mc_meim1988 wrote:I don't think its a rolling shutter issue.
