视频网站YouTube可以让人自由地上传视频，如果看到那种画质极烂的视频，网友通常会吐槽：你是拿土豆拍的吗？因而这种视频也被形容为potato quality（土豆质量）。

Potato quality is used to describe low quality videos.

“土豆质量”被用于描述那种质量很差的视频。

“Recorded with a potato” is a phrase commonly found in YouTube comments criticizing the resolution of a video that appears heavily pixelated, blurry or otherwise corrupt. The phrase can be also used as a snowclone in which potato is replaced with another object that is ill-equipped for video recording, such as a toaster, calculator or microwave.

“用土豆拍的视频”常见于YouTube的评论中，此语是批评那种画面上出现多个色块、画面模糊，或干脆出现整帧图像丢失的情况。这一用语也可以被“雪克隆”，就是把土豆一词换成其他没法拍摄视频的东西，比如烤箱、计算器或微波炉。（例：那个视频你是拿烤箱拍的吗？）

Example:

A: Dude did you shot this video with a potato?

B: Yeah I agree this video has the worse kind of potato quality.

甲：老兄你是用土豆录的这个视频吗？

乙：嗯，我也认为这个视频很蹩脚。
