    Chris, I'm trying really hard but I've never been able to sort out speed issues. EG, @1:05, you say, "It's worth noting that speed changes like this always occur from the head of the clip in the timeline. This means by speeding this clip up, I'm actually using more footage of the original media, but over the same duration of the clip in the timeline."
    1- Unless you're using Keyframes, don't all Inspector adjustments occur from the head of a clip? And continue throughout the clip?
    2- More footage from the original media? If you have a 2 sec airplane clip on the timeline and you adjust speed from 100% to 200% then, at 24FPS, you have 48 frames and you need an additional 48 frames, total 96? Else the clip shortens and you have a timeline gap. Are you saying Resolve goes looking in the media pool to find the original footage of the airplane clip to grab an additional 48 frames? If so, my mind is blown. And maybe this is where the "head of the clip" tip becomes important somehow? And if the original in the media pool was only a 2 sec clip anyway, there are no additional frames to add?
    To me this is a similar issue that I also don't understand: Adding a transition at the junction of 2 clips and Resolve refuses to do so. Maybe because the clips are too short to accommodate the transition so the solution is to try and drag the clip, or both clips, longer to accept the transition. [My suggestion to Resolve: Just shorten the transition!] And what happens exactly inside a clip when you successfully drag it longer, is it duplicating frames, but often refusing to be dragged? I understand other editors don't balk, they just make a transition work by some method I don't understand either. Is this the same case as above if Resolve is trying to go back up to the media pool for more frames but I had already put the entire clip on the timeline?
    I'm baring my soul here as I've found your videos to be clear and precise, so I think my brain is lacking a key basic fact or two in how Resolve acts. If you understand what I'm struggling with and can respond I would be grateful. Thank you.

      @jer3006 Ok, sounds like a video on working with clip handles may be on the cards here, but I'll try and help...
      Let's say you have a 10 second clip in the Media Pool but only use the first 5 seconds of it in the timeline.... This means you have another 5 seconds of unused footage of this same clip. This "unused" footage is what we refer to as a clip's "handles". If I change the speed of this clip to 200%, the clip on the timeline is still 5 seconds long, but Resolve will pull the extra unused frames into the clip in the timeline so all 10 seconds of the original clip is used but it'll play in the 5 second duration of the timeline clip. When I refer to making changes "from the head of the clip", I mean the first frame of the clip in the timeline says the same, but subsequent frames of the clip are adjusted based on the change to the clip speed - this is more relevant when the timeline clip isn't using the first frame of the original Media Pool clip.
      Same result if I change the frame rate.... take our 5 second clip @24fps.... By changing the framerate to 48fps, I'm doubling the number of frames playing per second (the same change as at 200%) and the same thing happens - the additional frames are brought in from the unused clip handles.
      At no point can Resolve magically create new frames that don't exist beyond the original clip, so if you change the framerate of our clip to 96fps (400% of it's original 24fps) then the clip has to be shortened to 2.5 seconds.
      Same for transitions... When adding a transition between two clips you need "overlapping" footage either side of the two clips where the transition will be applied. If you don't have these handles on either clip, the transition you're specifying can't be applied.
      Try this: instead of dragging a transition from the Effects library to the timeline, click on the edit point to select both sides. If one of those sides is red, there're no handles of the original clip, so the overlap needed for the transition is not available, and the transition can't be applied. Press CMD-T or CTRL-T to add a transition and a warning box appears informing you the clips have insufficient handles.
      Phew! HTH!

      @@Chris.Roberts You are amazing to respond with such help- sincerely, thank you.
      ► Handles are the "unused" footage in the media pool?! Say what? I thought they were the little graphic nodes you use to stretch shapes and clips, and fade clips/music. No wonder I didn't understand certain basics.
      ► "Resolve will pull the extra unused frames into the clip in the timeline so all 10 seconds of the original clip is used." Again, I thought when you a dragged a clip or a portion of a media pool clip on the timeline it was a severed copy and no longer had a connection to the media clip original. Wow, lots of intelligence in Resolve.
      Okay, so trying to rewire my brain here, anytime I stretch a clip on the timeline, Resolve is going to the "Mother" clip in the media pool to find a handle it can use to make the clip longer. If I shorten a clip on the timeline, it is just tossing frames out. And, per your last tip above, if my CTL-T on the edit point shows red on an edge, it means Resolve has actually checked the media pool clip and determined there is no additional footage available (the handle) that Resolve can kind-of-automatically add to the timeline clip to accommodate the transition. So, regardless that I thought there is enough footage in the 2 clips for the transition, there probably is not. But Resolve is going try to retrieve extra footage from the Mother clip that I purposefully did not want on the timeline to satisfy the need for handles? No wonder my success rate with transitions is < 1%.
      The timing (re-timing) speed and frames needed for the change is starting to sink in, thank you very much for your time to reply to my comment. As for the transition conundrum, I'll keep working until I get a "handle" on it- sorry, puns are just another fault in my wiring. You've given me a lot to rethink and work with, and I appreciate it. Oh, maybe I can add a transition to an Adjustment clip, look in Settings > User tab > Editing section > General Settings section to determine its duration, then compare that to my 2 clips to see if they are, simply, just too short for the transition.

    A really helpful video Mr. Roberts. But could you please let me know where to source the footage from?

    • @Chris.Roberts
      @Chris.Roberts  11 месяцев назад +2

      Thanks! All the footage I've been using so far has been from the official Blackmagic Design training guides. The airplane (aeroplane?) footage is from the Beginner's Guide and the Organ Mountain Outfitters footage is from the Editor's Guide. If you want to try the techniques out for yourself using this footage, you can download it from www.blackmagicdesign.com/products/davinciresolve/training#books

    I just encountered this speed up and ripple the last few days. Is there a method to only speed up the clip with its current In- and Outpoint without rippeling the timeline? I usually trim a clip by the content it contains and not the length, so when I speed it up I want it to start and end where I have already cut, but without rippling the timeline because that is also already timed correctly. I hope I could make my problem understandable :)

      🤣 In that case you'll want to watch Part 2... Yes, you can do what you're asking, but you need to use the Retime Controls for a clip... Stay tuned as they say!
