Frame by frame render

PostThu Dec 02, 2021 10:21 am

Hi

Is it possible to render a short clip frame by frame? I know I can use the jpeg2000 format but that produces a format which I cannot load into any photop editor. Ideally I would like to be able to render the clip - frame by fram - as jpg files.

Any suggestions anyone?

You can do it by using a saver node in fusion page.

1. If the clip contains any effects/color corrections, select it and create a new compound clip.
2. Go to the fusion page and add a Saver node
3. Go to the inspector and click the Browse button
4. Change the format from "OpenEXR files" to "All Files"
5. Name the file and add a .jpg extension at the end, click save
6. Go to the inspector and switch to the Format tab, set the jpg compression quality
7. Go to the fusion menu and select Render All Savers.

In Resolve you can render to a few image sequence formats:
- JPEG 2000
- EXR
- DPX
- TIFF
- Maybe some others I forgot?

But definitely not JPG or PNG.

For use in a standard photo manipulation app, TIFF is probably your best bet; though some will open EXR also. Not sure about DPX.

If you absolutely must have JPG, you could go through Fusion:
  1. Drag an adjustment clip from the Effects Library, to the timeline
  2. Drag the AC from the timeline, to the Media Pool
  3. Delete the one on the timeline
  4. Drag the one from the Media Pool back to the timeline, putting it on the highest video layer (above all other clips) and drag its right edge to make it the full length of the timeline.
    (Note that steps 2, 3 and 4 are required due to a bug with Adjustment Clips - you can't just drag one from the Effects Library to the Timeline, else the frame numbers will start at 80,000+, which would affect your later Saver render)
  5. Right-click on the Adjustment Clip -> Open In Fusion page
  6. Add a Saver node, and connect the MediaIn node to it.
  7. In the saver, configure it to save to "Filename.jpg", in whatever location ('filename' can be whatever name you want of course.)
  8. Fusion menu -> Render all Savers
  9. This will produce an image sequence called Filename0000.jpg, FileName0001.jpg, etc, for the full timelline.

There are Dolby Vision situations where you need to provide a TIFF sequence, and that can work very well.

Exporting TIFF frames is not that hard, but it is a bit time-consuming and takes up a lot of space, since it's uncompressed. I have to ask the o.p.: what situation do you have that specifically requires a JPG sequence? That's pretty unusual in my experience.
