DaVinci Resolve (DR) Directions/Comments:


A) Disclaimer: We have used DR for a total of about 1 hour, so if anything below is wrong, incomplete, or not the best way of doing something, please forgive.

B) When installing, you need to find the installer window that shows installation is finished, containing a button to close the installer, etc. We mention this, because the progress window — a different window — keeps looking like the application is installing, even after it has finished and that other window is present, waiting for user input...

C) We first installed DR 17 on a Windows 10 laptop with only modest CPU, RAM, and motherboard GPU. In that environment, it just kept crashing. So we installed it on a much more powerful quad core Window 10 desktop, with lots of RAM, powerful nVidia graphics card, etc. There, it has so far worked fine.

D) When DR starts up, it may show the message "Looking for control surface" for a long time...
In that regard:
- Up to say 10-60 seconds, this is likely "normal", where Black Magic Design (BMD) says it is just that they don't update the message. In other words, the search for control surface (a hardware device providing editing controls) happens almost instantaneously, but then lots of other initialization happens, but they don't update the onscreen message.
- HOWEVER, there is also another thread with users describing it taking 10-15 minutes to get past that message, which is a bug of some kind...

E) DR project files, unlike other suites we have used like Adobe CC, are stored in a database and so a simple Save-As does not work to place project in desired folder. The location for the database can be seen/modified via the File | Project Manager | Show Databases icon click | "i" Info to show detail, and then hover over database path.
(There is also an "Export Project" option that we believe may write the database entry of relevance to wherever you wish, in some format we have not explored.)


1) Download DR free version from and install it.

2) Start it up and on the top menu select File | New Project | Create.

3) Assuming the bottom menu item selected is Media, then top menu File | Import selection will include Media as an option. (If Media is not selected in the bottom menu, then the top menu may have Import | Media grayed out.)

4) When you import the media, you will likely get a query re changing Project Framerate to match Media. We did so match and think in general that is the correct thing to do.

5) Once you import the media, it may take a while (tens of seconds for even a relatively short clip) for media to actually appear in media clip icon view, be scroll-able, etc. We believe what is happening is that DR is taking temporally-compressed footage (we opened an H264 .mp4 file) and creating a format better suited for backward/forward scrolling (e.g., by making each frame temporally stand-alone.)

6) Right-click on the clip and select Create New Timeline Using Selected Clips, and just accept the defaults.

7) Left-click on the newly created timeline icon (not sure this is necessary, but won't hurt), and then click the Gear icon on the lower right of the environment windows.
Ignore the Timeline Resolution dropdown (unless it has what you need), and just type in the desired pixel res directly below it. (While the drop-down selection above won't immediately change when you do this, the next time you click the gear icon to open the dialog, it will show "Custom".)
And we changed the 10 bit video to 8 bit — see no reason not to and likely will speed things up during editing. (Think this is just for display — nothing to do with export, which needs to be, and is, 8 bits/channel.)

8) On the bottom menu, click the Deliver item. When you do this, on the left (at least that is where it was on our default workspace layout) there will appear Render Settings. Select Format: QuickTime, Codec: Photo JPEG (Yay!!!).

9) There are then Video, Audio, and File buttons in the render panel.

a) Video: For the compression, choose the lower of the two options (not the "Best", which is likely much larger/slower-at-run-time than you need, and will be visually no better) and, in general, choose 70-80%. And choose square pixels.

b) Audio: Uncheck the Export Audio checkbox.

c) File: Enter a desired filename.

10) Right above the timeline, where you see the movie, you can select Render: "Entire Timeline" or "In/Out Range". Generally you will probably want Entire Timeline. (The In/Out range is, we believe, set by the thin gray bar just above the movie timeline, should you ever need it.)

11) Select the Add to Render Queue bottom at the bottom of the left-hand Render panel. When you do that, it will ask you for a file path for the to-be-rendered movie.

12) The movie in question will then be added to the Render Queue, shown on the right-hand panel. Once you confirm it is there, you may select the Render All button further down.

The above should hopefully do it. If there are issues, feel free to contact us.
