Convert TXT to MP4

A phone, television, social platform, or presentation system may accept an MP4 video but not a plain-text document. Creating the video requires rendering the text into timed visual frames, optionally adding narration or music.

What the TXT format is

.txt is a plain-text format that stores characters without document layout. Notepad, TextEdit, code editors, terminals, word processors, and logging systems commonly create TXT files. The file may use UTF-8, UTF-16, or a legacy character encoding, but it contains no fonts, images, page structure, display timing, audio, or video frames. Those properties must be added during video production.

What the MP4 format is

MP4 is a multimedia container based on the ISO Base Media File Format. It can hold video, audio, subtitles, and metadata; H.264 video with AAC audio is the common combination for broad compatibility, but MP4 itself does not mandate those codecs.

Rendering text as MP4 is useful for slide-like pages, scrolling announcements, timed captions, narrated documents, and social-media posts. Unlike TXT, the result is not inherently searchable or easily editable, and it is usually much larger than the source text.

Choose the type of video

• Visual text video: display each passage on a slide, card, or scrolling background for a chosen duration.
• Narrated video: generate speech from the TXT file with a text-to-speech application, then combine the audio with text frames or captions. Balabolka is a practical Windows option; other TTS applications can export WAV or MP3.
• Captioned video: create a timed SRT or WebVTT file and burn the captions into the video, or keep them as a separate subtitle track when the target player supports it.

Using PowerPoint

1. Create a blank presentation and select the required aspect ratio, such as 16:9 for landscape or 9:16 for vertical video.
2. Divide the TXT content into readable sections and place each section on a separate slide. Use a large sans-serif font, high contrast, short lines, and enough empty space for the intended display size.
3. Set each slide's duration through Transitions → Advance Slide → After. Add generated narration, recorded speech, or music through Insert → Audio.
4. Export through File → Export → Create a Video or the equivalent video-export command in the installed desktop edition. Select recorded timings or the configured seconds per slide, choose Full HD when appropriate, and save as .mp4.

PowerPoint is suitable when the text should look like designed pages. The exact menu and video-export availability depend on the desktop edition and operating system.

Using Shotcut with text cards

1. Split the TXT content into sections and create one PNG or JPG card per section in PowerPoint, an image editor, or another layout tool.
2. Open Shotcut, import the cards, and place them on the timeline in order.
3. Set each card's duration, add transitions and an audio track if required, then choose Export → Presets → H.264 High Profile.
4. Export with an MP4 filename and check the result on the intended device.

Shotcut is free and keeps private text on the local computer, but it does not automatically convert raw paragraphs into scenes; the cards and their timings must be prepared first.

Using FFmpeg for timed text

For scripted production, create a UTF-8 subtitle file with one timed entry per section. An SRT file such as captions.srt can contain:

1
00:00:00,000 --> 00:00:05,000
First section of the document.

2
00:00:05,000 --> 00:00:10,000
Second section of the document.

With an audio file whose duration covers the captions, render a 1920×1080 black video and burn in the subtitles:

ffmpeg -f lavfi -i color=c=black:s=1920x1080:r=30 -i audio.mp3 -vf "subtitles=captions.srt:force_style='FontName=Arial,FontSize=40,PrimaryColour=&HFFFFFF&,Alignment=5'" -c:v libx264 -pix_fmt yuv420p -c:a aac -shortest output.mp4

The installed FFmpeg build must include the subtitles filter, commonly provided through libass. Replace Arial with a font installed on the system that contains every required character. Without audio, remove -i audio.mp3, -c:a aac, and -shortest, and add a fixed duration such as -t 10; otherwise the generated color source has no natural end. Subtitle timing, line wrapping, font selection, and duration remain manual.

Using online video editors

Browser editors such as Kapwing, VEED, and Canva can create text scenes, captions, and narration before exporting MP4. Typically, paste the TXT content into text layers or import a subtitle file rather than expecting a dedicated one-click TXT conversion. Check current export limits, resolution, watermarks, and privacy terms; do not upload confidential documents unless the service is approved for that data.

Quality and compatibility limits

• TXT has no pixels or formatting to preserve. Readability depends on font size, contrast, line length, animation, and how long each passage remains visible.
• For narrated text, estimate timing from speech speed: about 150–180 words per minute suits ordinary narration, while technical material generally needs slower delivery or shorter scenes.
• Use UTF-8 when saving the TXT and subtitle files, and choose a font containing the required accented characters, scripts, and symbols. Emoji support varies by font and video renderer.
• Use 1920×1080 for standard landscape video or 1080×1920 for vertical video. H.264, AAC, and yuv420p provide broad hardware and software compatibility.
• Keep the original TXT as the searchable, editable source. An MP4 render can contain burned-in text that cannot be selected or corrected without re-exporting.
