Video files are just files, so any general-purpose bulk renamer can change their names. The difference between a good result and a broken folder comes down to two things: whether the tool preserves the correct extension, and whether it can read the information that makes a video filename useful, resolution, codec, duration, and frame rate, or a season and episode number for a TV library.
Five tools cover almost every video renaming job. Windows File Explorer handles simple sequential numbering with no install. PowerToys PowerRename adds find-and-replace and regular expressions. Advanced Renamer is the standout for video because it reads embedded video metadata and writes it into the filename. FileBot specializes in matching TV episodes and movies against online databases. On macOS, Finder has a built-in Rename Items dialog, and a short bash mv loop covers scripted jobs. Each is described below with a real before and after.
Windows File Explorer: F2 for Simple Numbering
The fastest option on Windows needs no download. Open the folder, select every video file with Ctrl+A or a click-and-drag, then press F2. Type a single base name such as ClientMeeting and press Enter. Explorer applies that name to the whole selection and appends a number in parentheses, so the files become ClientMeeting.mp4, ClientMeeting (1).mp4, ClientMeeting (2).mp4, and so on. The original extension is kept automatically, which is what you want.
This method is ideal when the files belong together and just need a clean, countable name. It is the wrong tool when you need to keep part of each original name, insert a date, or read anything from inside the file, because F2 can only apply one base name across the selection. For a raw folder of camera clips that all came from the same session, though, it is the quickest path from chaos to order. A before and after: Clip001.mov becomes 2024-11-15_ClientMeeting_01.mov once you combine the F2 base name with a manual date prefix, or simply ClientMeeting.mov and ClientMeeting (1).mov for pure numbering.
PowerToys PowerRename: Find, Replace, and Enumerate
When the built-in F2 is too blunt, Microsoft PowerToys adds PowerRename, a free utility that puts a proper bulk-rename dialog into the right-click menu. Install PowerToys, enable the PowerRename module, then select your video files, right-click, and choose PowerRename. A panel opens with a search box and a replace box, and a live preview list shows the new names before you commit anything.
PowerRename does plain find-and-replace, so you can strip a camera prefix like GX01 from every clip, or swap spaces for underscores across the whole selection. Turn on the regular expressions option and it becomes far more powerful: a pattern can capture the meaningful part of a messy name and rebuild it in a consistent shape. The Enumerate Items option appends a sequential counter, so a batch of raw exports lands as Reef_Dive_01.MP4, Reef_Dive_02.MP4, and upward. Because the preview updates as you type and you can scope changes to filename only, PowerRename is the safe everyday choice for renaming video on Windows without touching the extension.
Advanced Renamer is where video renaming gets genuinely video-aware. Unlike the tools above, it reads the technical metadata embedded in each video file and lets you write those values straight into the filename. That means the resolution, codec, duration, frame rate, and creation date can all become part of the name, information no find-and-replace tool can produce because it lives inside the file rather than in the old name.
The workflow uses method tags. Add the files, then build a naming method from tags such as the video-width and video-height for resolution, the codec, the frame rate, and a counter for sequence. A method might read out as a base name plus the resolution plus an incrementing index, which turns an anonymous GX010042.MP4 into Reef_Dive_1080p_01.MP4. Advanced Renamer shows a full preview column so every proposed name is visible before you apply the batch, and it keeps the extension intact by default. For anyone organizing footage by quality or format, being able to stamp 1080p, 4K, h264, or 60fps directly into the filename is the feature that sets this tool apart from every general renamer. It runs on Windows, with community workarounds for running it on macOS.
FileBot: TV Episodes and Movie Libraries
For a media library rather than raw footage, FileBot solves a different problem. It matches video files against online databases and renames them into the clean season and episode format that media players expect. Drop a folder of vaguely named episodes onto FileBot, choose a matching source, and it identifies each file and rebuilds the name with the show title, the SxxExx code, and often the episode title, so Episode1.mkv becomes ShowName_S01E01.mkv, or a movie file gains its correct title and year.
FileBot works across Windows, macOS, and Linux, and its strength is exactly the thing the other tools cannot do: it knows which episode is which. It is overkill for a folder of personal clips, and it is the right and often the only sensible choice for anyone tidying a series or film collection where the correct S01E01 pattern matters for library software to recognize each file.
macOS Finder and a bash mv Loop
On a Mac, Finder has a capable renamer built in. Select the video files, right-click, and choose Rename, and macOS opens a Rename Finder Items dialog. The Format option adds a name plus an index or a counter, the Replace Text option does find-and-replace, and Add Text prepends or appends a fixed string. Selecting several clips and applying a Format of a base name with a numbering suffix produces Interview_01.mov, Interview_02.mov, and so on, with the extension preserved.
For scripted or repeatable jobs, a short shell command is faster than any dialog. A loop such as one that iterates over the .mov files in a folder and moves each to a numbered name gives full control, and because it runs in Terminal it can be saved and reused across shoots. The one rule with a manual mv loop is to keep the extension in the target name, since the shell will happily rename a file to something with no extension if you let it. Used carefully, it is the most flexible option on macOS for people comfortable at the command line.
Video renaming tools compared

| PowerToys PowerRename | Find-and-replace, patterns, enumerate | Yes | No | Windows |
| Advanced Renamer | Names from resolution, codec, frame rate | Yes | Yes | Windows |
| FileBot | TV episodes and movie libraries (S01E01) | Yes | Partial, via database match | Windows, macOS, Linux |
Video-Specific Concerns to Get Right
Three things separate a good video rename from a broken folder. The first is the extension. Video containers such as .mp4, .mov, .mkv, and .m4v tell the operating system and media players how to open the file, so the rename must never drop or alter the part after the final dot. Every tool above keeps the extension by default, but a hand-written mv command or a careless find-and-replace on the whole name can strip it, so always confirm the extension survives in the preview.
The second is metadata-based naming. A filename that carries the resolution and codec, like Reef_Dive_1080p_01.MP4, is searchable and self-documenting in a way that a plain counter never is. Advanced Renamer is the tool that reads those embedded values, which is why it is worth reaching for whenever the technical shape of the footage matters.
The third is season and episode patterns. Media libraries depend on the SxxExx convention, so Episode1.mkv renamed to ShowName_S01E01.mkv is not cosmetic, it is what lets player software group and label a series correctly. FileBot exists to produce exactly that pattern reliably. Match the tool to the concern: numbering for raw clips, metadata tags for footage organized by quality, and database matching for episodic content.
A Note on the Paperwork Around a Shoot
One honest clarification, because it comes up often: renamer.ai renames documents and images by reading their content, and it does not process video or audio files, so the clips themselves need the native tools described above. Where a content-aware document renamer can help is the paperwork that surrounds a shoot, the release forms, location contracts, and vendor invoices, which are the documents renamer.ai is built to organize while the footage is handled elsewhere.
Renaming multiple video files at once is straightforward once the right tool is in hand. Reach for File Explorer F2 or Finder for fast sequential numbering, PowerToys PowerRename for find-and-replace and patterns, Advanced Renamer when the resolution or codec should live in the filename, and FileBot for any TV or movie library that needs the S01E01 format. In every case, preview the result and confirm the extension is intact before applying the batch. For readers who also deal with scanned paperwork alongside their footage, the same principles of previewing and consistent naming carry over to a workflow for how to rename scanned PDF files.
