AI Video Editing for Online Courses and Tutorials
Valmera helps course creators turn recorded lessons into edited video through chat. Upload your footage, ask for specific cuts and captions, review the teaching sequence, then create the final MP4 in Studio. The aim is a lesson a learner can follow, with time saved on repetitive editing.
Use it for narrated screen recordings, talking-head explanations and filmed demonstrations. Bring the recording and lesson plan; organize the course and publish it in your course platform. Account creation and uploads are free. Editing starts with a paid plan at $15/month.
Choose a recording with the kinds of retakes, terminology and screen detail found across your course. Use it to settle the editing brief, check the final file and estimate the remaining review work.

1. Choose the lesson outcome and delivery format
Write what the learner should be able to do after this lesson. List the steps and result they must see. Choose the course player's format before cropping; a landscape software walkthrough and a vertical promotional clip need separate framing decisions.
2. Upload one lesson and check the source
Create a project for the lesson and upload the recording. Main videos support MP4, MOV, M4V, WebM and MKV, subject to both the 14 GB and three-hour limits. Wait for upload and analysis, then inspect the transcript and preview. Small source text needs to be readable before you edit it.
3. Mark the teaching steps to preserve
Identify the prerequisite, each action, the visible result and the exercise. Include source timestamps or exact spoken phrases. Keep useful thinking time and demonstrations that happen without speech. A pause detector cannot decide whether a learner needs that moment.
4. Make a focused first cut
Ask for the verified setup chatter, failed take or repeated explanation to be removed. Preserve the order of the complete demonstration. Review that cut before adding presentation effects, so a shortened lesson still teaches the whole procedure.
5. Correct captions and emphasize the right detail
Check technical terms, names, numbers and negations in the transcript. Request readable captions and only the zooms that help explain a step. Keep controls, formulas and results visible. Fixing transcript text changes the caption wording; it does not rerecord a spoken error.
6. Watch the preview as a learner
Follow the full procedure from the preview, including transitions between cuts. Check that narration describes the action currently shown and that a learner can see the result before the next step. Request a precise correction and review the new version.
7. Create the final MP4 and publish in your course platform
Select the reviewed version, create the final export in Valmera Studio, and download the finished MP4. Watch the actual file before uploading it to the course platform. Prepare any separate caption track and course materials against that final edit, then check playback in the destination player.
Illustrative edit plan: an eight-minute spreadsheet lesson
Suppose the lesson teaches a learner to export a spreadsheet and verify the saved file. The plan below removes setup and duplication while preserving the inputs, export action and result check. This is a planning example; it has not been rendered in Valmera. Replace these ranges with observations from your own recording.
| Source range | Planned edit | Teaching reason |
|---|---|---|
| 00:00–00:20 | Remove | Microphone setup before the lesson starts. |
| 00:20–01:05 | Keep | The goal and prerequisite explain why the procedure matters. |
| 01:05–01:40 | Remove | A failed take is replaced by the complete demonstration that follows. |
| 01:40–04:30 | Keep | All inputs, menu choices and the export action are visible. |
| 04:30–04:45 | Shorten to 5 seconds | Reduce waiting while retaining the visible save confirmation. |
| 04:45–06:10 | Keep | Opening and inspecting the exported file verifies the result. |
| 06:10–06:25 | Remove | A repeated recap line adds no new instruction. |
| 06:25–08:00 | Keep | The recap and practice task let the learner apply the procedure. |
This plan retains 6 minutes 40 seconds of program content: 8 minutes minus 80 seconds. Treat that as an editing target, then check the actual preview and exported file. Removing the result check merely to hit six minutes would weaken this particular lesson.
If the cut skips the confirmation dialog, identify the missing source range and ask to restore it. Refer to both the current preview time and original source time so the instruction is clear. The timeline and edit history help you review the intended version. For a published rendered example of Valmera edits, see the original-footage trim and reframe example.
Prompts to adapt for your lessons
Keep your style preferences in a reusable brief. Replace the objective, timestamps, protected steps and terminology for every lesson. These are suggested instructions to adapt and review.
First cut of a narrated screen recording
This lesson teaches [one outcome]. Keep the complete steps [list], the result check and the practice task. Source times are measured in the original upload. Remove [verified ranges] and retain [protected ranges], including the quiet demonstration. Preserve landscape framing. Make this first cut without adding music or zooms; I will review the procedure before styling it.
Caption and screen-detail pass
Use the current reviewed cut. Check caption spelling for [technical terms]. Add readable white captions with a dark background, positioned away from [controls/formula/result]. At [current preview time], gently zoom toward [visible detail] while keeping [context] in frame, then return to the wider view. Keep the narration clear. Render a preview for review.
Repair a cut that removed a teaching step
In the current preview at [time], the lesson jumps from [before state] to [after state]. Restore the explanation and visible action from source [start–end] between those moments. Keep the rest of the reviewed edit. Recheck caption timing around the restored step and render a new preview.
A second reviewer can use the same brief to check the output. Reusing a prompt helps define the desired style, but each recording still needs its own edit, review and final export. Keep a simple lesson list with the project name, reviewed version, filename and publication status.
Prepare captions and delivery for the course player
Choose the caption deliverable before styling. Valmera can burn captions into the exported picture. Studio does not import or export SRT/VTT files. If learners need a selectable caption track, plan the platform's caption workflow or a separate captioning tool around the final edited MP4. Timing from the uncut recording will drift after sections are removed.
Thinkific documents external SRT uploads and an automatic-caption option with plan restrictions. Check which is available for your account, and review the captions after the video is processed. Its closed-caption guide describes both paths. This is a separate step in Thinkific.
For Udemy delivery, its published video standards specify at least 720p and horizontal 16:9 video. Check the actual final file against its current video standards. Keep a separate edit for vertical promotional clips so the lesson's screen detail remains intact.
Review caption meaning as well as spelling: a missing “not,” an incorrect decimal or an omitted sound cue can change an instruction. W3C's caption guidance covers speech, relevant non-speech sound, timing and correction of automatic output. Complete any additional accessibility work your teaching content requires.
Final video rendering uses the original upload, but the MP4 is a rendered export rather than an unchanged copy of the source. Check small text, audio, caption position, actual duration, branding and any end card. Upload the finished file yourself and test the lesson in the destination player. Platform guidance above was checked September 7, 2026.
A review pass that protects the lesson
- Follow every required action from the edited video, with prerequisites and results visible.
- Check each cut between narration and a screen change. Restore context when the two disagree.
- Read formulas, code and menu labels at the size learners will actually use.
- Check captions against the audio, including names, units, numbers and important sound cues.
- Listen for abrupt edits and music covering speech; retain useful pauses and practice time.
- Watch the downloaded final MP4 and verify any separate caption track in the course player.
For future updates, identify the obsolete step and record its replacement with compatible framing and audio. Ask to replace that specific section, then review the surrounding explanation and caption timing. Keep the rest of the approved lesson where it is still accurate.
