Download YouTube Videos for Premiere Pro and After Effects

Why do some YouTube files fail in Premiere Pro?#

YouTube files fail in Premiere Pro because of the codec inside them, not the file extension. As of September 2026, a download of YouTube’s best streams usually holds VP9 or AV1 video with Opus audio, and none of those three appear in Adobe’s list of formats Premiere imports natively.

Premiere Pro has no built-in way to download a YouTube video. You download a file first, then import it, and what Premiere can do with that file depends on its decoders. Adobe says so directly: MOV, MP4 and MXF are containers, and Premiere “can import these container files,” but reading the data inside depends on the codecs installed.

The failure shows up in three ways. A VP9 file triggers an unsupported compression message that names VP09. A WEBM or MKV file is refused at import, because neither container is on Adobe’s list. An MP4 whose picture decodes but whose audio is Opus can arrive silent, since Adobe lists AAC, MP3, WAV and AIFF audio, not Opus. The container side of the problem is covered in MOV vs MP4 vs MKV vs WEBM for video editing.

Ema Zamboni, who made B-ROLL, cuts YouTube videos in DaVinci Resolve Studio on Windows 11 and hit the same wall there: 4K60 AV1 downloads were heavy to play back, and AV1 or VP9 files crashed Resolve at times. B-ROLL’s automatic ProRes and DNxHR conversion was built to solve that problem, and it produces the kind of file Adobe lists for both Premiere Pro and After Effects.

Which format should you download for Premiere Pro?#

Download ProRes or DNx from B-ROLL’s Format menu for Premiere Pro. Both options convert the download into a .mov with an intraframe codec that Adobe lists as native for Premiere Pro on Windows and macOS, while MP4, MKV and WEBM keep YouTube’s own streams.

Each B-ROLL format option is compared by what the file contains and whether Adobe’s format lists name it for Premiere Pro and After Effects.

B-ROLL has no codec preference setting, so its MP4 row is the one that surprises editors. B-ROLL’s MP4 keeps YouTube’s own codec, usually VP9 or AV1, so for Premiere Pro the dependable download is a ProRes or DNxHR .mov. The wider choice for every editor is laid out in the best format to download YouTube videos for editing.

An intraframe codec stores every frame as a complete picture. ProRes and DNxHR work that way, so scrubbing, reverse playback and trimming in the timeline never wait for the decoder to rebuild frames from a long group of pictures, which is how VP9, AV1 and H.264 store video.

How do you download for Premiere Pro with B-ROLL?#

B-ROLL downloads the best streams for the Quality you pick into an MKV master, then converts that master with ffmpeg into a ProRes or DNxHR .mov with the same name. The numbered steps at the end of the page cover the clicks; the settings that matter for Premiere are these.

Format. Choose ProRes or DNx. The menu marks both “slow” because the conversion is a second, CPU-heavy step that uses all cores, one file at a time. The next download starts while the previous file converts, so a queue keeps moving.

Quality. Best, 4K, 1080p, 720p and 480p are height caps. Pick the height of your Premiere sequence: a 4K master for a 1080p timeline doubles the frame size in each direction and makes the .mov four times the pixels to decode.

Tier. B-ROLL picks the tier for you. It measures the source bitrate on the MKV master and takes the lightest ProRes or DNxHR tier whose reference rate, scaled to the video’s frame size and frame rate, is at least 10 times that bitrate. A 1080p 30 fps source at 8 Mbps gets DNxHR SQ, estimated by the app at 124 Mbps, or ProRes 422 LT at 102 Mbps. How B-ROLL chooses and what each .mov contains is on download YouTube videos in ProRes or DNxHR.

Only a part. For a short cutaway from a long talk, choose Only a part: ask me which each time in Advanced options. Clips are named Title [mm-ss to mm-ss].mov, so the Project panel shows the time range at a glance. The name carries minutes and seconds only, so a part that starts at 1:05:30 reads [05-30 to ...]. The preview player needs VLC installed; without it you type Start and End times.

Files. The .mov lands in %USERPROFILE%\Downloads unless you changed the SAVE TO folder, next to a .credits.txt with the creator and source link. The resolution and frame rate of the source are kept, so New Sequence From Clip in Premiere gives a sequence that matches the footage. More workflows by editing app are collected in YouTube footage from download to timeline.

ProRes or DNxHR: which works better in Premiere Pro on Windows?#

Both work in Premiere Pro on Windows: Adobe lists Apple ProRes as supported “on macOS and Windows” and names DNxHR LB, SQ, HQ and HQX. For a Windows edit that stays in Premiere, DNxHR is the natural pick; for a project that goes to a Mac, a colorist or Final Cut Pro, pick ProRes.

The files B-ROLL writes differ in bit depth. B-ROLL’s ProRes is always 10-bit 4:2:2, while its DNxHR is 8-bit 4:2:2 (LB, SQ or HQ) unless the source is 10-bit, which gets HQX at 10-bit. For an 8-bit source, DNxHR matches the bit depth without storing bits the source never had.

Disk space is similar at the top tiers. Apple lists ProRes 422 HQ at 220 Mbps for 1920 x 1080 at 29.97 fps, which is 1.65 GB per minute (220 Mbps x 60 s / 8 bits per byte / 1,000). Avid lists DNxHR HQ at 25.99 MB/s for the same frame size and rate, which is 207.9 Mbps (25.99 MB/s x 8), or 1.56 GB per minute.

B-ROLL moves up to those HQ tiers only for richer sources. At 1080p 30 fps it picks DNxHR HQ for a source above 12.4 Mbps and ProRes 422 HQ above 14.7 Mbps: the next tier down’s reference rate divided by 10 (124 / 10 for DNxHR SQ, 147 / 10 for ProRes 422).

The full side-by-side, including Resolve and Avid, is in ProRes vs DNxHR for editing. For long 4K timelines on a slower PC, Premiere proxies are the other lever; proxies vs transcoding for YouTube footage explains when a proxy workflow is worth it on top of a converted .mov.

What changes for After Effects?#

After Effects reads the same B-ROLL .mov files: Adobe’s After Effects import help says that in MOV, After Effects has native import support for Apple ProRes, Avid DNxHR, Avid DNxHD and H.264. Nothing about the download changes; only the length of what you download does.

Adobe’s After Effects file format list names QuickTime (.mov), MPEG-4 (.mp4, .m4v) and MXF as containers it imports, with the same caveat as Premiere: the codec inside decides. WebM and Matroska are not on the list, and neither are VP9 or AV1. For audio, After Effects lists AAC and M4A, AIFF, MP3 and WAV, so a B-ROLL WAV drops straight into a comp and a FLAC or OPUS file does not.

Compositions usually need seconds, not minutes, and every frame of a long file costs render time and disk cache. B-ROLL’s Only a part mode downloads just the range you mark, and Exact frame cut (slower, re-encodes) in Advanced options makes the clip start on the requested time instead of the nearest keyframe. For a screen replacement or a reference layer, a 5-second 1080p ProRes 422 LT clip at B-ROLL’s 102 Mbps estimate is 64 MB (102 x 5 / 8).

In After Effects, check Interpret Footage after import. B-ROLL keeps the source frame rate, so a 29.97 fps YouTube video stays 29.97 fps, and the composition should match it unless you plan to conform the footage.

How do you import YouTube subtitles along with the clip in Premiere?#

Choose SRT in B-ROLL’s Subtitles menu, then import the .srt file into Premiere Pro, which lists SubRip (SRT) among its supported caption formats. B-ROLL saves the file next to the video as Title.lang.srt, one file per language you tick; with more than one file, the SRTs move into a Title - subtitles folder.

Before the first download of a batch, B-ROLL’s Subtitles dialog lists the languages the video really has, split into official subtitles uploaded by the creator and auto-generated ones. Tick Only official subtitles when you want the creator’s own text rather than YouTube’s automatic transcript.

Two details matter in Premiere. Subtitles for a clip cover the whole video, carry the video’s timecodes and are named after the video, so the Interview.en.srt that comes with Interview [02-10 to 02-38].mov starts at the beginning of the full video, not at 2:10; shift the caption track in the timeline to line it up. The Embedded option does not embed subtitles into clip files, so for a clip pick SRT.

The import dialog, caption styling and lining up captions with a trimmed clip are covered step by step in import YouTube subtitles into Premiere Pro.

What goes wrong most often with YouTube footage in Premiere Pro?#

The most common mistake is importing a file B-ROLL did not mean for the edit: an MP4 with VP9 video, a leftover MKV master, or a WEBM. Each one has a quick check and a fix.

• VP09 or unsupported compression at import. The file holds VP9 or AV1. Download it again with ProRes or DNx selected. The error, its cause and every fix are in Premiere Pro VP09 not compatible: fix for YouTube files.
• An MKV where the .mov should be. B-ROLL deletes the MKV master after a successful conversion. If the log says “DNx transcode failed; keeping the MKV.”, the conversion did not finish: download the video again rather than importing the MKV.
• The card says “converting” for a long time. The conversion uses the whole CPU and scales with length and resolution. Download only the part you need, or pick a lower Quality cap that matches your sequence.
• Colors look wrong on an HDR video. yt-dlp prefers HDR streams and B-ROLL applies no tone mapping, so an HDR source arrives as HDR in a 10-bit file. Set up the Premiere sequence for HDR or choose a different source.
• “Sign in to confirm you’re not a bot.” As of September 2026 YouTube asks some downloads for a signed-in session. Export a fresh cookies.txt from a browser signed in to your own YouTube account and load it in B-ROLL’s Settings; cookies expire, so export again when the message returns.
• The timeline stutters with a 4K .mov. An intraframe 4K file asks the disk for hundreds of megabits per second: B-ROLL estimates DNxHR SQ at 496 Mbps for a 2160p 30 fps source at 20 Mbps. Drop the Quality cap to your delivery size, or attach proxies in Premiere.
