    Hi Mark, no stupid questions... if they're actually genuine.

    Thanks for the reply, and yes, a genuine question on my part. Didn't realize that PP was prone to this issue (but I don't use it so I am ignorant of a lot of things about PP).

    I also use ffmpeg now to create H.265 files since Resolve's encoders are not very good. I can get SIGNIFICANTLY fewer artifacts if I export to DNxHR, and then use ffmpeg to convert to H.265 than if I export from Resolve as H.265. 

    Thanks for sharing your workflow when delivering. I know quite a few people complain about the h.264 encoding in resolve. Didn't know that h.265 is chock full of artifacts, too.

    Hmmm.... looks like I am going to install ffmpeg soon. Seems so strange that the best way is to send it to an intermediate codec and then a final, but I guess that is the way it has to be.

  2. As most of you are aware by now, i am pretty much the king of stupid questions. I am sure that many on this forum will attest to the fact that the stupidity of my questions knows no bounds.

    So I have to ask as to why you would be transcoding your h.264 files to ProRes in the first place. I am sure you probably have a good reason to do so. Just, it escapes me at this time.

    I'd really like to shoot in SLOG 2 on my Sony cameras (RX100 V, A7III) but have noticed that this picture profile has a negative impact on the autofocus performance. Especially in back-lit scenes the camera tends to focus on the light background rather than the foreground, I can imagine this being due to the lack of contrast in the image (I am using PDAF though). In any other Picture Profile the autofocus seems to work excellent.

    Is this a known issue with regards to shooting in SLOG?

    I don't have an RX100 nor an a7 III, but autofocus works well when shooting in slog 2 on my a6500.

    I often shoot in bad lighting and the only time I have noticed it glitch out is when I am temporarily panning across something like a solid color wall, and it usually just loses focus momentarily.

    Otherwise, it seems to be fine. I have probably shot between about 500 to700 short (under 20 seconds long) clips in Slog 2 and I think I have only noticed it twice struggling in the conditions I mentioned above.

    f4 is the same no matter the sensor size

    Well... yes, if you are interested only in exposure.

    it ain't the same if you are comparing depth of field at equivalent focal lengths.

    Also, if it means using the same ISO value among different sensors, then sensor performance is generally going to be better on the larger sensor.

  5. When doing slow motion in Resolve, you are going to want to go in to your project settings (the gear in the lower left) and look for the retming settings. make sure it is set to optical flow and I would select the better quality.

    Then when exporting, make sure that you are exporting at a high enough bitrate that you won't get artifacting.

    I often shoot 4K footage at 30p and slow it down to a 24p timeline for just a minor slow motion effect." It looked fine on the timeline, but when I was rendering  it to youtube, I had the bitrate too low and it made it look quite weird.

    Goat's eye has some tutorials that are very thorough and easy to understand, although they are a little dated since they were created for resolve 12 and 12.5. However, still very relevant.

    I would suggest looking at Avery Peck's tutorial on using LOG footage with Resolve color Management if you regularly work with LOG footage (or RAW footage for that matter). The new Resolve Color Management in Resolve 15 has some fairly sophisticated tools in it so you aren't just just dropping random lLUTs on to your footage and hoping for the best.

    I sold my Sony a7s and all my Sony lenses, battery grip this week. So I am in the market LoL.

    I thought you were going to pull a Charlton Heston with your a7s:

    "Pry it from my cold, dead hands!"

    Maybe @Andrew Reid can start working on a NEW camera profile called a7SHD where we can give new Fuji, Nikon and Canon cameras those lovely green skin tones from the original a7S???

    webrunner, it would be fantastic if you stopped linking to wolfcrow.

    OK, I'll bite...

    What are the reasons people are dismissive of wolfcrow?

    He seems to me to know what he is talking about and has had (apparently) enough time with several different camera models to present opinions backed up by experience.

    Maybe I am missing something that is obvious to everyone else? (Wouldn't be the firs time...)

    I also have this problem and am searching for a solution. I just made a project that used super slow pans, and I am getting this jittery effect despite the pans being very slow. I'm shooting, wide open at 25fps, and 1/50. 

    I am beginning to think it is the IBIS that is the cause. It makes no sense to not see blurry pans, but instead see a succession frames with no blur, which is what it looks like. Is the IBIS  fighting the panning motion?

    I used the a6500 with IBIS on and with a crane initially and the result was awful. The corners of the footage was vibrating vert slightly, and noticeable when the gimbal was held still for still handheld shots.

    When not using the crane, with IBIS on, it also has this jittery pan effect, but not the vibrating corners (which I gather is the IBIS fighting the crane stabilisation). 

    The question is, does it happen with IBIS off? In which case, what is the point of IBIS for video? This is why I bought this camera. 

    I am the original poster of this thread and still using the same a6500, same Sony 10-18 lens, and same original Crane gimbal as when I started this thread.

    I haven't really compared turning IBIS off and leaving it on to see if it makes a difference. Maybe over the next few weeks as business slows down I will have more time to do so.

    I have found that panning a lot slower, and also shooting at 30fps but putting it on a 24fps timeline, helps out quite a bit with overall smoothness. Of course, I do videos of architecture, so it is not like I have to worry about audio problems or anything like that when conforming 30fps down to 24fps.

    There were suggestions to use a slightly slower shutter speed than half the FPS rate. So use 1/50th instead of 1/60th shooting at 30fps. I have done that - mostly to deal with low light scenarios - and it does seem to work a bit. But then, what's the point in shooting in 4K if everything is kind of blurry???

    If you think the colors from the GH5 are pretty good, rent the GH5S for a few days, and you'll see just how great the GH5S is over the GH5.

    Of course the GH5S has great colors... it uses a sensor made by Sony :)

    Seriously, though, did not know that the GH5S has even better colors.

    From my experience of having used the GH5 extensively and now a new X-T3 user, the X-T3 files blow the GH5 away in H265.

    I am wondering / hoping this might be a bit of hyperbole. Maybe you can elaborate on this a bit :)

    yes, I have been impressed with what I have seen of the colors coming from the X-T3 (in particular using the eterna profile).

    But it seems to me that the colors coming from the Panasonic are pretty good as well.

    Is it really that much of a time-saver to get pleasing results from the X-T3 compared to the GH5? For instance, in 4K 60p is the 10-bit 4:2:0 of the X-T3 better than the 8-bit 4:2:2 out of the GH5???

    Thanks in advance for any elaboration you can provide.

    Just finished a book of photos of my son’s first 5 years....

    Good on ya. Wish I had done that.

    That both of these cameras self destructed on the grounds of taste?

    :)

    If that were possible, I would have NO working cameras left (instead of the six I have lying around, if you include my drones and my Olympus 3030 zoom that I have been too lazy to take down to the electronics recycling center).

    Could be worse, it is not on fire like California is!!

    What's going on with the climate... It's bonkers.

    Yeah, I had a photo shoot of a condo for sale in Tiburon, which overlooks the north part of the San Francisco Bay. It would normally be a two-million-dollar view (literally), but there was so much smoke in the air, the view of the Bay was ruined.

    Around here it literally looks like a scene from Blade Runner 2049. About three months back we had another large set of fires, and we just had the one-year anniversary of the Sonoma County fires that destroyed large parts of the city of Santa Rosa.

    This is why I didn't keep my a6300 or bought the a6500. I got three lemon a6300 from separate batches.. the trust is gone.

    Wow! I am surprised to hear that. I use my a6500 HARD and have never had a problem with it. On the other hand, I know Sony lenses have a bad reputation for quality control from batch to batch (or from lens to lens), so I guess I shouldn't be surprised about that.

    If trying to do a slider imitation with a gimbal you could always shoot in 60p and slow the footage down. You can get some pretty slow movements with practice. Having a lens with OIS helps and having a two handled attachment for your gimbal also helps.

    True! I would also suggest that shooting at 30fps and putting the footage on a 24fps timeline also helps with gimbal / fake slider / fake jib shots in general (my a6500 has pretty nasty 1080p so I am often reluctant to shoot it at 60fps).
