9. Finishing the Courier Short

Making nine shots look like one film

Nine accepted shots with a good mix still look unfinished for one plain reason. Each shot was generated on its own, so each came back a little brighter or darker, a little warmer or cooler, than the one beside it. Finishing fixes that in two passes, then wraps the result. First you correct each shot so they all match. Then you lay one look, called the grade, over the whole scene. Then you add titles and captions, export the versions you need and watch them where they will actually play. That is the work this chapter carries out on the courier scene, in the same Shotcut project the show's example has used all along. The walkthrough is illustrative. It describes what you would do, not something you have already done.

Start with titles, because they are quick and they set the frame. Shotcut makes text with filters. The simplest route is a color clip. Open the Open Other menu, choose Color, pick black and add it to the start of the timeline. Select it, open the Filters panel, click the plus button and add Text: Simple. Type the short's title, choose a plain font and set the size so it reads on a phone. If you want more than one line styled differently, or a name and a subtitle laid out on purpose, use Text: Rich instead, which works like a small word processor inside the frame. Either filter can also sit on top of a picture shot if you would rather title over the wide walk than over black.

Two habits keep titles readable. Keep text well inside the edges of the frame. Some screens and players crop the borders, and a phone's interface draws buttons over them, so leave a margin of roughly a tenth of the frame width on every side. Then give the words time. A rule that works is to read the title aloud slowly twice and hold it at least that long, which for a short title is around three seconds. Add a fade in and fade out of about half a second using the fade handles at the top corners of the clip, so the text does not snap on and off.

The closing credits carry something easy to forget. The sound pass logged every effect's source and licence, and any file under a Creative Commons Attribution licence, the kind called CC BY, needs written credit in the work. Open that record now and copy each CC BY sound into the credits: the sound's title, the creator's name, the licence and where it came from. Sounds from the YouTube Audio Library need no credit, and generated sounds from a paid ElevenLabs plan need none either, but list them in your own records. Put the credits on a second black color clip at the end, with Text: Rich so the lines line up. Hold them long enough to read every name, which for four or five lines is about six to eight seconds.

Captions come next, even though nobody speaks in this scene. Plenty of people watch with the sound off, and the knocks are part of the story. A muted viewer who sees a raised hand but no answer misses why the courier gives up on the door. A caption such as "two knocks" or "rain falls" carries that sound to them.

A caption file is a plain text file, and the common format is SRT, short for SubRip Subtitle. Each caption in it has three parts. The first is a number, counting from one. The second is a start time and an end time, written as hours, minutes, seconds and milliseconds, with an arrow between them. The third is the text. A blank line separates one caption from the next. So caption one might say: number one, from about two seconds to four seconds, "two knocks." Caption two might cover the rain under the wide walk.

In recent versions of Shotcut you can build this inside the editor. Look in the View menu for Subtitles, which opens a panel where you add a subtitle track and type each caption at the playhead. Then export that track as an SRT file. If your version has no Subtitles panel, writing the file by hand in any text editor works just as well. Find the start and end of each sound on the timeline, note the times from the timecode display, and type the lines.

Keep the captions as a separate file instead of burning the words into the picture. YouTube Studio lets you upload an SRT under Subtitles for your video. That way viewers can switch captions on or off, the text stays sharp at any screen size, YouTube can display it in a readable style, and you can fix a typo later without exporting the whole film again. Burned-in text is permanent and covers the frame for everyone.

Now the main job, the color. Two words get mixed up here, so separate them first. Color correction makes shots match each other and look true: neutral greys look grey, brightness sits in a sensible range, every shot feels like the same moment. A grade is a creative look applied on top of that, like a slightly cooler, moodier rainy night. Correct first, then grade. If you grade shots that do not match, the grade magnifies the differences.

You judge color with video scopes, not just your eyes, because eyes adjust to whatever they look at. In Shotcut, open the View menu, then Scopes, and turn on the Video Waveform and the Video RGB Parade. The waveform draws the frame's brightness from left to right. The left of the scope is the left of the picture, the bottom is black and the top is white. A bright window on the right of the frame shows as a tall streak on the right of the waveform. The RGB parade shows the same kind of picture three times, side by side, once each for the red, green and blue channels. When something in the frame should be neutral grey, like the courier's grey rain jacket, its trace should sit at about the same height in all three. If the red column sits higher, that area has a warm cast.

Pick one shot to be the reference and match everything to it. Use the wide walk. It shows the street, the rain, the jacket and the window glow from screen right, which the production bible fixes as the scene's light direction. That glow is supposed to be warm, and the rest of the street cool. Keep that relationship in every shot. If a shot's glow has turned cool, or the street has turned warm, it does not match.

Go shot by shot. Put the playhead on the wide walk, look at the scopes and remember roughly where the jacket sits and how high the brightest part reaches. Then move to the next shot. If the jacket's three parade traces are uneven, add the White Balance filter and either adjust its color temperature or use its picker on the jacket to make that grey neutral. If the whole shot is too bright or too dark, add the Color Grading filter. It has three wheels, for shadows, midtones and highlights. Lowering the midtone level darkens the body of the picture while leaving the deepest blacks and brightest highlights roughly in place. Nudging the highlight wheel toward orange warms the window glow. Make small moves and compare back to the wide walk often, both on the scopes and by cutting between them.

Then judge it in the cut, not one frame at a time. Say that when you play the scene through, the reaction close-up jumps out. On the waveform its trace sits noticeably higher than the sign insert before it and the wide walk after it, so her face looks lit by a different evening. Fix only that shot. Select the reaction close-up, add Color Grading, bring the midtones down until the face sits where the phone close-up's face sat, and check the glow still reads warm on screen right. Play across both cuts again. If it now settles in, leave every other shot alone. This is the same rule the show used for continuity repairs: find the one shot that breaks the match and change only it.

Once all nine sit together, add the grade. Keep it gentle. One way is a Color Grading filter with a slight cool push in the shadows and a touch of contrast, the same settings on every shot. Another is the LUT (3D) filter, which loads a lookup table file, usually a cube file, that remaps colors to a prepared look. If you use a LUT, read its licence like any other asset and turn its strength down if it is heavy. After applying the grade, check three things in every shot. Skin should still look like skin, not grey or orange. The grey jacket should still read as grey, not teal. The rain should still be visible against the street, not crushed into black. If any of those fails, the grade is too strong.

Finally, export and inspect. Use the same YouTube export settings the sound pass used, give the file a clear version name, and export the master. If you plan to post a vertical cut-down for Shorts or similar feeds, treat that as a separate version with its own project at a nine by sixteen frame, reframed shot by shot. It is an option to plan, not something this short needs. Then watch the export where it will play. Upload it as unlisted, add the SRT, and watch on a phone and on a computer, with sound and with captions on. Check that titles sit inside the margins, captions appear on the knocks, the reaction close-up no longer jumps and the loudness still sounds right.

Keep everything together in the project folder: the Shotcut project, the master export, the SRT file, and the rights records for every sound, LUT and font. Then total the cost. The cost log puts the seven new shots at about five hundred and sixty-six credits, about eighty per accepted shot. Add whatever you paid for sound, such as a month of a paid ElevenLabs plan if you used one. The earlier shots, the first accepted clip and the crouch and rise clips, had their own costs. List them as separate lines rather than guessing a figure, so the total says plainly which parts are logged and which are not. A finished piece with an honest cost record is what lets you estimate the next one.

Copying one grade onto every clip

Applying the same grade nine times by hand invites mistakes, so here is the shortcut. Shotcut can copy a clip's filters and paste them onto others. Select the clip that carries the finished grade, then open the Edit menu and choose Copy Filters, or right-click the clip on the timeline and choose it there. Select the other clips, holding Control, or Command on a Mac, to pick several at once. Then choose Paste Filters. Every selected clip gets the same filters with the same settings.

Two cautions. Paste copies every filter on the source clip, so if that clip also carries its own correction, like the reaction close-up's darker midtones, you will spread that correction everywhere. Copy from a clip whose only filter is the grade, or remove the extras after pasting. And the pasted copies are independent. If you later decide the grade is too cool, you must change it on one clip and paste it again to all the others.

If your Shotcut version lets you put filters on the whole output, you can avoid that. Select the Output entry at the top of the timeline and add the grade there once. It then applies to everything below, and one change updates the whole film. Check the result on a title card, since the grade will tint your black and white text as well. To inspect it, play across two or three cuts and confirm every shot shifted the same way.
