Hi there

Does anyone know of a way to export subtitles out of a project? I have a project with a tonne of subtitles in an FX track but when I export an aaf or xml to grade in Davinci, none of them seem to be showing up. Is there a way to export them as an srt file?

Thanks a lot

Hi,

You can't export subtitles from Lightworks text effects as srt file (nor any other standardized subtitle format).

I might be corrected on this, but I'm not aware of any kind of EDL that can be used to carry text effects from Lightworks to Resolve and back.

Assuming that you do not change timing in Resolve you can render after grading to an intermediate format (e.g. Cineform, YUYV), import it into Lightworks, create a sequence and copy and paste the FX tracks containing the subtitles from your original edit, and export for delivery.

Another way could possibly be to make a copy of the sequence in Lightworks, replace video tracks with black, export an image sequence which then contains the subtitles over black background and create a composite with a masked blend in Resolve. If you find a way to export an alpha channel with transparency out of Lightworks you can use a blend without masking.

Obviously all the text and associated metadata exists in the edit file - but don't believe there is any routine to extract that - though I can't be completely sure it has not been included in XML exports. A direct question to LW might help you on that.

If you are wanting the text itself to rebuild in your finishing process that may be tough - if you want a version to lay over based on the LW generated output I'd export a video in the highest frame-size-resolution possible - make it the text only over black or key-able colour of your choice - centre screen the text and enlarge it to the maximum possible width - that will give you the best quality material to reduce back to subtitle positioning.

It may also be good to include a BITC panel reference showing the edit time.

Just to confirm, in FCP5 XML export there isn't any information about text effects.

Thanks for all the advice folks. I think I'm just going to guts it out and redo them all.

If you have the patience to copy and paste them out into a text file you can rebuild your subtitle track in AegisSub which has a good audio waveform display. Bit of a fiddle to begin with but I can't do without it now.

Only downside is you have to convert from .ass to .srt at the end but there are plenty of ways (even websites) to do that.

As far as I know Resolve supports only FCPXML (of FCPX) files for import of subtitles. How to create those?

Having checked, I found that Aegisub can indeed export SRT files so you can simply pop them through the converter on this page to make FCP XML files.

Blurb from the website says:
A free program that converts SRT subtitle files to FCPXML 1.5,
perfect for creating subtitles compatible in Final Cut Pro X and DaVinci Resolve.

abcowan you have subtitles in an FX track in Lightworks. Are you required to bake in subtitles to the completed video for some reason ? I am mostly required to provide SRT files to accompany the final rendered video, or to incorporate these in a DVD.

Yes and that is very unfortunate, as well as the missing import option for .srt, .sub files and the like.

A long time ago I requested the above, still it didn't make it into the product.
Too often I have a sequence in a foreign language where subtitles are required.
Using external titling tools, defining via timecode where a certain title should appear, and importing/exporting the titles in a standardized way into/from the NLE is the actually professional approach.
E.g. you only need to define once:

  • whether the titles should be burnt in or kept as separate metadata,
  • the font type, size, color, shading etc.
  • the relative positions (x/y) on the screen

Sure one can discuss whether that should be part of the NLE or rather an authoring tool. But how often do we export the final product (e.g. for web publishing) out of Lightworks nowadays and that's all?

Anyway, I am really missing this.

Me too!

I've now done these subtitles three times. And it's in two languages - sooooo boring, and not exactly a useful allocation of my tim. I look forward to Lightworks 15 - maybe that will have this useful functionality........

It's for a film I'm rendering out to DCP in two days and I'm pretty sure I need them burned in there. Oh for an SRT import/export option!

Maybe this should go into the request section. I would also like a hard copy of the effects that I use.

abcowan with benefit of hindsight - perhaps a more useful workflow might have been to use subtitling software to produce a keyable output for the LW stages of the work - then you would have all the text on a dedicated special-purpose platform.

Here an example how PowerDirector deals with it - since quite a couple of years:
This image is hidden for guests. Please log in or register to see it.

You can import subtitles from either an .srt or a .txt file.

There is a separate track for the subtitles and a subtitle "room" where you can arrange your subtitles.
Each line with a subtitle is represented by start and end time.
In addition to the import file option one can also arrange individual titles manually (as it was done in the screenshot). So also when an .srt sequence was imported one can still add more titles if required.
Font type, size and color can be chosen and are then valid for the entire edit (sequence).
You can also choose between burning in the subtitles or keep them as separate metadata (so you can export them alongside the video as well).

If the metadata option is chosen, for standardization reasons (DVD, BluRay etc.) the options regarding font type, size and color are limited.
