Add Title Clip

Right-click on empty space in the project bin, or click the kdenlive-add-clipgo-downAdd Clip icon on the project bin toolbar, and select Add Title Clip.

This opens the built-in Title Editor.

See Title Clips for more details.

Here is a script courtesy of Grog (see his post for more details and how to use it in Windows) that turns subtitles into titles that can be further edited in the Title Editor:

     1#!/bin/bash
     2
     3read -p "frame rate:"$'\n' frate
     4[ "$frate" = "" ] && frate=60
     5echo "..."
     6
     7[ -d ./Kden_Titles/ ] && rm -r ./Kden_Titles
     8mkdir -p Kden_Titles
     9
    10readarray -t frm < <( (sed -n '2~4p' ./*.srt) )
    11readarray -t sub < <( (sed -n '3~4p' ./*.srt) )

    14w=$(bc<<<"length(${#sub[@]}*2)")
    15
    16for i in "${!frm[@]}"; do
    17
    18        b=$(date -d "${frm[i]:0:12}" "+%S.%3N")
    19        e=$(date -d "${frm[i]:17:12}" "+%S.%3N")
    20        ee=$(date -d "${frm[i-1]:17:12}" "+%S.%3N")
    21
    22        if [ "$i" -eq 0 ]; then ee=0; fi
    23        if [ "$(bc<<<"$b<$ee && $i!=0")" -eq 1 ]; then b="$(bc<<<"$b+60")"; fi
    24        if [ "$(bc<<<"$e<$b")" -eq 1 ]; then e="$(bc<<<"$e+60")"; fi
    25
    26        blank="$(bc <<< "($b*$frate+0.5)/1-($ee*$frate+0.5)/1")"
    27        duration="$(bc <<< "($e*$frate+0.5)/1-($b*$frate+0.5)/1")"
    28
    29        if [ "$blank" -gt 0 ]; then
    30        sed -e "s/30/$blank/" -e "s/%s//" ./*.kdenlivetitle* > ./Kden_Titles/"$(printf "%0*d" "$w" "$n")"_.kdenlivetitle
    31        ((n++))
    32        fi
    33
    34        sed -e "s/30/$duration/" -e "s/%s/${sub[i]}/" ./*.kdenlivetitle* > ./Kden_Titles/"$(printf "%0*d" "$w" "$n")".kdenlivetitle
    35        ((n++))
    36
    37done
    38
    39sleep 1
    40echo "Titles in $PWD/Kden_Titles"$'\n'
    41touch ./Kden_Titles/*_*
    42
    43$SHELL
    

The highlighted lines point out the %s variable (the same used as the standard placeholder for template titles). You can change that to anything you prefer, like placeholder, for example.

Here is the same script but for Powershell in Windows (save it as .ps1):

    # Prompt for frame rate
    $frate = Read-Host "frame rate"
    if (-not $frate) { $frate = 60 }
    Write-Host "..."
    
    # Remove existing Kden_Titles directory if it exists
    if (Test-Path -Path "./Kden_Titles/") { Remove-Item -Path "./Kden_Titles/" -Recurse -Force }
    New-Item -ItemType Directory -Path "Kden_Titles"

    # output File name width / counter
    $w = [math]::Ceiling($sub.Count * 2)

    $n = 1

       # Add 60s if necessary
       if ($i -eq 0) { $ee = 0 }
       if ($b -lt $ee -and $i -ne 0) { $b = [math]::Round([double]$b + 60, 3) }
       if ($e -lt $b) { $e = [math]::Round([double]$e + 60, 3) }
