Software to add text to video (bonus question of audio lowpass)

I've shot with my 6d and 85mm. Took the footage into Resolve to do editing/coloring. But I wan't to put up a running tally in the lower corner. Something I could use to mark at this point in the video I want this text/number then at this point change to this text etc.

Also I want to take the high hiss out with an audio lowpass filter what software would you use for that. Right now I'm considering finishing edits, exporting just the audio, pulling it into Reaper, modifying, exporting, then muting the audio on the video and adding the modified audio track. But that seems a bit cumbersome for simple hiss reduction.

Traditionally, this was called a timecode window burn. Blackmagic calls it a data burn, because there are a few other options besides timecode.Click the "flame" icon, right side of the toolbar on the color page. There are options.

You can access a parametric EQ from the Mixer, or, adjust clip EQ. Details in the audio chapter of the manual. Probably a good resource.

If you’ve not updated to the latest version of Resolve you should - that’s where some of the audio goodness was added

Excellent. No I haven't updated in over a year I'd guess. This is awesome, I was thinking I'd have to use 4 different programs to get this done. Thank you.
