B-roll from YouTube: Rights, Clips, Codecs and Credits

What is b-roll and why source it from YouTube?#

B-roll is supplementary footage cut over the main story (the A-roll) to illustrate a point, cover an edit or set a mood. YouTube is a tempting source because it holds real places, events, products and people that stock libraries may not have, and some creators publish their footage under Creative Commons Attribution (CC BY) precisely so others can reuse it.

Using YouTube videos as b-roll works in four steps: rights, clip, codec, credit. Rights decide whether you may use a shot at all. Clip, codec and credit decide whether the shot behaves on your timeline and whether you can show, months later, where it came from.

B-ROLL, the app, is named after this kind of footage. Ema Zamboni, a video editor who cuts YouTube videos in DaVinci Resolve Studio on Windows 11, built it with Claude to collect b-roll for those edits. The sourcing checklist pairs each step with the question to answer and the B-ROLL feature that helps with it.

Which YouTube footage can you use as b-roll?#

You can use YouTube footage as b-roll only when you hold a right to it. That means your own uploads, videos under CC BY, public domain material, footage the owner has licensed or permitted, or a use you judge to be fair use or fair dealing. Everything else under the Standard YouTube License needs the owner’s permission.

As of September 2026, YouTube Help lists two license types: the Standard YouTube License, which is the default for every upload, and CC BY, which lets other creators reuse the work on the condition that they credit it. Public domain footage is a separate route with its own checks, covered in where to find public domain footage and how to credit it.

Fair use is the weakest route for plain b-roll. YouTube’s fair use page says courts decide each case on its own facts and weigh four factors, among them how much you borrow and whether your use harms the market for the original. The same page says adding new expression or meaning weighs toward fair use, and names commentary, criticism, research, teaching and news reporting as typical purposes. A cutaway that only fills the screen does none of those things.

Downloading is a separate question from copyright. The YouTube Terms of Service do not allow downloading content unless the service expressly permits it or you have written permission from YouTube and the rights holders. The routes, the risks and the rules outside the US are laid out in can you use YouTube clips in your video.

How do you find Creative Commons b-roll on YouTube?#

YouTube’s own search finds Creative Commons b-roll: search for the subject, open the search filters and choose Creative Commons, as YouTube Help describes it as of September 2026. Then open each result and confirm the license in the video’s description before you download anything.

Treat the filter as a shortlist, not as proof. YouTube Help says a creator may mark a video CC BY only when it is their original content, content already under CC BY, or public domain material, and that a video with a Content ID claim cannot carry the license. A CC BY label on a reupload of news, film or TV footage deserves suspicion, because the uploader may not own what they licensed.

B-ROLL has its own search for the technical half of the job. Type words instead of a link and the Paste & Download button becomes Search, with 20 results that show title, channel, duration, views, bitrate and resolution. The results do not show the license, so compare quality in B-ROLL and check rights on YouTube: right-click a result and choose Open on YouTube to read the license on the video page.

Keep a record of what you checked. A screenshot of the video page with the license visible, saved next to the clip, shows what the page said on the day you downloaded. The full CC BY picture, from the license terms to the credit format, is in Creative Commons on YouTube: find, reuse, credit.

How do you download only the shots you need?#

B-ROLL downloads only the range between an in point and an out point, so a shot from a long video never costs you the full download. Turn it on in Advanced options (the ⋯ button next to Subtitles) by choosing Only a part: ask me which each time.

Clip files are named after the video and the range, for example Interview [02-10 to 02-38].mov, so the bin tells you where each shot came from. The name carries minutes and seconds only: a part starting at 1:05:30 is named [05-30 to ...], and two parts with the same minute and second in different hours collide.

The default fast cut snaps to keyframes, so a clip can start a little before your in point. Tick Exact frame cut (slower, re-encodes) in Advanced options when the first frame matters. Either way, mark a second or two of handle on each side.

The preview plays at up to 720p and sets in and out points to the whole second; the download itself uses your Quality setting. Without VLC, B-ROLL asks for Start and End times in a small “Download which part?” prompt instead.

B-ROLL prefers YouTube’s HLS streams for clips, because seeking deep inside one large stream could stall a clip download for minutes. Clips cut from deep inside long videos used to stall that way; the HLS preference fixed it. The full feature is described in YouTube clip downloader with preview and in and out points.

Which format keeps b-roll edit-ready?#

ProRes or DNxHR keeps b-roll edit-ready. Both are intra-frame codecs, so an editing app decodes each frame on its own, while the MP4, MKV and WEBM options keep YouTube’s own codecs, often AV1 or VP9 video with Opus audio, which some editing apps play slowly or reject.

The problem is real on a working timeline. On Ema Zamboni’s DaVinci Resolve Studio projects on Windows 11, 4K60 AV1 footage downloaded from YouTube was heavy to play back, and AV1 or VP9 downloads crashed Resolve at times. B-ROLL’s automatic ProRes and DNxHR conversion was built to solve that.

Pick ProRes or DNx in the Format menu (both marked “slow”). B-ROLL downloads the best streams into an MKV master, then ffmpeg converts it into a .mov with the same name. The master is deleted after a successful conversion and kept if the conversion fails. Resolution and frame rate stay as published, and the audio becomes uncompressed 16-bit PCM.

B-ROLL picks the tier per video: the lightest ProRes or DNxHR tier whose data rate is at least 10 times the source bitrate, which the app’s code treats as visually transparent for an intra-frame codec. A 1080p source at 30 fps and 8 Mbps becomes DNxHR SQ, which the app estimates at 124 Mbps, or 0.93 GB per minute (124 Mbps x 60 s / 8 bits per byte / 1000). A 10-bit source converted to DNxHR always gets HQX.

The conversion is a second step after the download: it runs one file at a time, uses every CPU core and makes large files. Set Quality to your delivery resolution unless you plan to punch in. The codec side, editor by editor, is in best format to download YouTube videos for editing.

How do you keep credits for every shot?#

B-ROLL writes a .credits.txt next to every finished download and adds the same block to a running credits.txt in its folder. The option is Save credits (attribution) for each download in Advanced options, on by default; for ProRes and DNxHR, the file is written after the conversion.

Each block holds title, creator, channel URL, source URL, upload date, license and a copy-paste credit line. The example uses placeholder values; the app writes a long dash where a hyphen appears here.

Title:     Harbor at Dawn, Drone Footage
Creator:   Example Channel
Channel:   https://www.youtube.com/@examplechannel
Source:    https://www.youtube.com/watch?v=XXXXXXXXXXX
Uploaded:  2025-05-17
License:   Standard YouTube License

The License line is whatever yt-dlp reports, and it reads “Standard YouTube License” when nothing is reported, even if YouTube shows another license on the page. When yt-dlp reports a Creative Commons license, the file adds a Creative Commons block with a ready attribution line. Check the license on the video page every time: the credits file is a convenience, not proof of rights.

A CC BY credit needs four things, both in YouTube Help and in the Creative Commons attribution guide: title, author, source and license. The credits file carries all four. Creative Commons adds that there is no single correct format, only a reasonable one suited to the medium, so a line in the video description is a common home.

A clip gets its own file named after the clip, such as Interview [02-10 to 02-38].credits.txt, and its Source line is the full video URL without a timestamp. The lookup is best effort: if it fails, for example behind a sign-in wall, no credits file is written and no error appears, so check the folder before delivery.

MP4, MKV, WEBM and audio files also get title, uploader, date and URL embedded; ProRes and DNxHR files do not. Every field and option is listed in automatic credit files for every YouTube download.

How do you organize a b-roll library?#

Organize b-roll by project folder, because B-ROLL keeps one running credits.txt per folder. Point the SAVE TO row at the project’s b-roll folder before you download, and the clips and their credits collect in the same place, ready to hand to a client with the delivery.

The ▾ menu on the SAVE TO row keeps up to 6 recent folders, so switching between projects is one click. Turn on Save audio to a different folder when you also pull music beds or ambience, so audio downloads land in their own folder and video stays in the main one. Channel and playlist downloads made from the channel dialog go into a subfolder named after the channel.

File names already sort well: the video title first, then the time range for clips. The modified date on each file is the download date, not the upload date, so rely on the Uploaded line in the credits file when a date matters. Import the folder as a bin in DaVinci Resolve or Premiere Pro; the credits text files stay beside the media on disk.

B-ROLL remembers the last 200 finished downloads in its Completed view, and right-clicking one offers Open on YouTube and Open folder when you need to recheck a source. Folder structure, naming and bin mirroring are covered step by step in how to organize downloaded YouTube clips, and more workflows sit in the guides for YouTube footage from download to timeline.
