You've probably been there. You have three different clips from your phone or a screen recording session, and you just want them to be one single file. Naturally, you go to HandBrake. It’s the gold standard for transcoding, right? It’s free, open-source, and runs on everything from a dusty Windows 7 box to the latest M3 Mac. But here’s the kicker that trips up almost everyone: you actually can't combine videos with HandBrake in the way you think you can.
It sounds crazy. HandBrake is incredibly powerful. It can shrink a 4K MKV into a tiny MP4 without breaking a sweat, but the developers have been very clear for years that HandBrake is a transcoder, not a video editor.
The big HandBrake misconception
If you open HandBrake looking for a "Merge" button, you’re going to be looking for a long time. It isn't there. HandBrake processes files one by one or in a queue. You can drop a folder of ten videos into the window, and HandBrake will happily convert all ten of them into a new format, but it will spit out ten separate files. It won't stitch them together.
I've seen people spend hours trying to find a "Join" feature in the "Dimensions" or "Video" tabs. Save your breath. It's not a secret setting you haven't found yet. The software simply isn't built with a "stitch" engine. This is mostly because merging videos requires "re-wrapping" or "concatenating" streams, which is a different technical process than the frame-by-frame re-encoding that HandBrake does.
Wait.
There is a sort of "hacky" way to do it if you’re desperate, but it involves some serious caveats. If you have a DVD or a Blu-ray structure where the movie is split into several physical files (like VOB files), HandBrake can sometimes see those as a single "Title." If you point HandBrake at the folder rather than the individual file, it might combine them automatically. But for your MP4s or MOVs from your GoPro? No dice.
Why you might want to avoid HandBrake for joining anyway
Even if HandBrake could do it, it might not be the best tool for the job. See, HandBrake always re-encodes.
Every time you run a video through HandBrake, the software deconstructs the video and rebuilds it. This takes time. A lot of time, depending on your CPU. More importantly, every time you re-encode, you lose a little bit of quality. It’s like making a photocopy of a photocopy.

If you just want to combine videos with HandBrake to save space while joining them, that’s one thing. But if you want to keep the original quality of your footage, you want a tool that does "Stream Copying" or "Passthrough." This essentially just staples the two video files together without touching the actual pixels. HandBrake cannot do passthrough for video; it must re-encode the video stream.
Better alternatives that actually work
Since HandBrake is a dead end for simple merging, what should you use? If you’re on a Mac, honestly, QuickTime Player is the easiest "hidden" gem. You open the first video, drag the second video onto the window, and hit save. Done.
For Windows users or anyone who wants more power, Shutter Encoder is the real MVP here. It’s also free, and it’s built on the same underlying engine as HandBrake (FFmpeg), but it actually has a "Merge" function. You just throw your files in, select "Merge," and it finishes in seconds because it isn't re-encoding the whole thing.
Another heavyweight is MKVToolNix. It looks like something out of 1995, but it’s the most robust way to append files. It doesn't care about your resolution or frame rate—it just mashes the containers together.
When HandBrake is actually the right second step
Okay, so you’ve accepted that you need another tool to join the files. But maybe you still want to use HandBrake. Why? Because after you join those three massive, unoptimized 4K files from your camera, you now have a 15GB monster that won't play smoothly on your TV.
This is where the workflow actually makes sense.
- Use a tool like FFmpeg or LosslessCut to join the videos instantly.
- Take that one big "joined" file and drop it into HandBrake.
- Use a preset like "Web Optimized" or "H.265 MKV" to shrink it down to a manageable size.
This two-step process is what professionals actually do. They don't look for an all-in-one "magic button" because those buttons usually sacrifice quality or take ten times longer than necessary.

Mastering the "Queue" (The closest you'll get)
If your goal for trying to combine videos with HandBrake was actually just to get a bunch of files processed at once, you should learn the Queue system.
It’s easy to miss. You click "Open Source," pick your folder, and then instead of hitting "Start Encode," you click the little arrow next to "Add to Queue" and select "Add All." This doesn't join them, but it lets you walk away from your computer while it handles the heavy lifting of converting fifty clips into the same format.
Common Pitfalls when merging elsewhere
If you decide to go the FFmpeg route or use a different joiner, remember one thing: the files have to match.
If you try to join a 1080p video with a 720p video, most "joining" software will glitch out or the aspect ratio will look like garbage. They also need to have the same frame rate. Joining a 24fps cinematic clip to a 60fps iPhone video usually results in audio desync that will drive you absolutely insane.
If your clips are different sizes or frame rates, you actually should use a proper video editor like DaVinci Resolve or even CapCut. These programs will normalize the footage on a timeline so everything looks uniform when you export it.
The technical "Why"
The reason HandBrake doesn't support merging is rooted in its philosophy. It was designed as a "one input, one output" system. The code is optimized to look at a source and determine the best way to compress it. Adding a second source complicates the "rate control" (how the software decides which frames get more data).
If you look at the official HandBrake documentation or their community forums, the developers are pretty blunt about it. They have no plans to add a joiner. They believe in doing one thing—transcoding—really well, rather than doing five things poorly.

Actionable steps for your video project
Stop digging through the HandBrake menus. It's a waste of time. Instead, follow this path based on what you actually need:
Scenario A: You want to join files without losing any quality (and do it fast).
Download LosslessCut. It’s open-source and specifically designed to "concatenate" files. You just import the clips, make sure they are in the right order, and hit export. It will be finished before you can finish a sip of coffee because it isn't re-encoding.
Scenario B: You have clips with different resolutions or formats.
You need a real editor. Download the free version of DaVinci Resolve. Throw your clips on the timeline. This lets you add transitions, fix the audio, and make sure the "joined" video actually looks professional. Then, you can export it directly.
Scenario C: You absolutely must use HandBrake for the final file size.
Join the files first using the "Command Prompt" (if you're techy) or Shutter Encoder. Once you have that one single large file, then bring it into HandBrake. Choose the H.265 (x265) encoder for the best balance of size and quality. Set the Constant Quality (RF) slider between 20 and 23. This is the "sweet spot" for most people.
Final reality check
The internet is full of "guides" that claim you can combine videos with HandBrake by using weird plugins or older versions. Most of that is outdated or just flat-out wrong. Stick to the tools that are built for the job. HandBrake is the king of compression, but it’s not a tailor. Use it to shrink your masterpiece, not to stitch it together.
If you’re doing this for a YouTube upload, remember that YouTube's own editor used to allow simple joining, but they stripped that feature out too. The world is moving toward dedicated, specialized tools. Learning the difference between "transcoding" and "joining" will save you more time than any software "hack" ever could.
The best way to move forward is to get Shutter Encoder. It’s the closest thing to a "HandBrake that can also merge" that exists today. It uses the same engine, it's just as safe, and it actually has the button you're looking for.
