Vidditを使用してReddit動画を音声付きHDでダウンロードする方法

Reddit動画が常に音声なしでダウンロードされる理由

Here's the most frustrating thing about saving a Reddit video. You finally figure out how to grab the file, you open it on your phone, and it plays. Except there's no audio. Just silence over the picture.

This isn't your fault. It's how Reddit's video player works. The site streams the video and audio as two separate files and stitches them together at the last second when you press play. Most downloaders only grab the video half and miss the audio entirely.

The fix is a tool that pulls both halves and merges them for you. Our favorite is Viddit, and we'll walk through using it in a minute.

技術的な理由(簡易版)

If you've ever wondered why this happens, here's the short version. Reddit stores videos on a CDN called v.redd.it. Each post that has a video actually has two separate URLs behind the scenes: an MP4 for the picture and a separate file (usually AAC) for the sound. The Reddit web player downloads both at the same time and plays them in sync.

When you right-click a Reddit video and pick Save video as, your browser only grabs the MP4. The audio file gets left behind. Same thing with most general-purpose downloaders. They see the video URL, grab it, and call it a day.

A proper Reddit downloader has to fetch both files and merge them into a single playable MP4. That's an extra step most generic tools skip.

Vidditが対応するもの

This is broader than you might expect:

  • Native Reddit videos from v.redd.it (with the audio merged automatically)
  • Reddit GIFs (which are usually MP4s too, similar to Twitter)
  • Cross-posted Imgur videos
  • Redgifs links (a huge chunk of Reddit's video traffic)
  • Streamable embeds
  • Old Gfycat links (yes, those still kind of work)
  • Images from i.redd.it

It doesn't handle private subreddits, deleted posts, or anything behind a login wall. That's a Reddit limitation, not a Viddit one.

Reddit動画をステップバイステップでダウンロードする方法

ステップ1: Reddit投稿リンクをコピーする

On new Reddit or sh.reddit.com, click the share icon on the post and pick Copy link.

On the Reddit mobile app (iOS or Android), tap the share arrow at the bottom of the post and select Copy link.

On old.reddit.com, right-click the post title and pick Copy link address. Yes, old Reddit is still alive, and a surprising number of people still prefer it.

ステップ2: Vidditに貼り付ける

Open viddit.io and paste the URL into the input box. Viddit checks the link, figures out where the video actually lives (Reddit, Imgur, Redgifs, wherever), and pulls the available qualities.

ステップ3: 画質を選んでダウンロードする

You'll see options like 1080p, 720p, and sometimes lower. Click whichever you want. The file that downloads is a single MP4 with audio already merged. No extra steps, no separate audio file to deal with later.

Vidditを推奨する理由

The audio merging is the headline feature, but a few other things make it our pick over other Reddit-focused tools.

The audio merge is automatic. Most free Reddit tools either don't do it at all or charge for it. Viddit handles it on their server and hands you a finished file.

Cross-host support is solid. Reddit comments and posts cross-link to Imgur, Redgifs, Streamable, and a handful of other hosts. A lot of "Reddit downloaders" only handle native v.redd.it videos and choke on cross-posts. Viddit just figures out what host the URL points to and handles it.

The Android app integrates with Reddit's share sheet. If you read Reddit on your phone, this is a quality-of-life upgrade. You hit share on a post, pick Viddit from the menu, and the download happens. No copying URLs.

No signup, no daily limit, no watermark, no full-screen ads. Standard stuff but worth mentioning because so many free tools fail on at least one of these.

If you save Reddit clips even occasionally, Viddit is the one we point people to.

他の選択肢とそのトレードオフ

Right-click and save: fast, but no sound. You've already learned why.

Generic multi-platform downloaders: same problem. They grab the video stream and skip the audio. Even some of the popular ones miss this.

Reddit bot accounts (the ones that reply to comments with download links): unreliable. They break every few months when Reddit changes its API or rate limits. Sometimes they work, sometimes the bot is dead and nobody's noticed yet.

Browser extensions: same long-term problem as on other platforms. Reddit's site changes break them, and updates lag.

Viddit's edge is that it stays maintained specifically for Reddit and updates when something breaks.

よくある問題と迅速な修正

Downloaded video has no sound. You used a non-Reddit-aware downloader. Re-paste the same link into Viddit and it'll merge the audio in.

"Post not found." The post was either deleted, the subreddit went private, or the user wiped their account. Try a cached version on the Wayback Machine if you really need it. Sometimes Google's cache still has it for a few days too.

Cross-posted video failed to download. The original host (Streamable, Imgur, whatever) might have deleted the file. Reddit keeps the comment thread alive even when the video itself is gone.

The download finished but the video is choppy. Try a lower quality. Some videos that were uploaded at one resolution and re-encoded for streaming get a bit broken on the highest quality option.

Reddit動画についてもう一つ

If you've used Tweeload, the audio issue probably sounds familiar. Twitter has a similar quirk where the video and audio streams need to be combined properly, and naive downloaders miss it. That's part of why we built Tweeload in the first place. Same kind of problem on a different platform.

Our Twitter GIF download guide covers the analogous case for X. The same principle applies: any platform that uses adaptive streaming or separate audio tracks needs a dedicated tool, not a generic one.

まとめ

Reddit videos lose their sound because the audio is a separate file. Viddit fixes that by merging both halves on the server before handing you the download. Three steps: copy the post link, paste it, pick a quality.

Next time you find a Reddit clip worth keeping, Vidditでダウンロードする and you'll actually hear the audio.
