用手机拍短视频,很多人抱怨“画质不行”“不够清晰”。但大多数情况下,问题不在手机,在设置。默认的拍摄设置是为“随手拍”优化的,不是为“短视频”优化的。改几个参数,画质能提升一个档次。
Many people complain about "poor picture quality" and "insufficient clarity" when shooting short videos with their mobile phones. But in most cases, the problem is not with the phone, it's with the settings. The default shooting settings are optimized for "casual shooting", not for "short videos". Changing a few parameters can improve the image quality by one level.
分辨率选1080P,帧率选30fps或60fps。 4K分辨率看起来更清晰,但文件体积大、剪辑卡顿、上传后抖音也会压缩。1080P是短视频的“甜点分辨率”。帧率方面,30fps适合大部分内容,60fps适合运动镜头或需要慢动作处理的画面。

Choose 1080P resolution and 30fps or 60fps frame rate. The 4K resolution looks clearer, but the file size is large, the clips are stuck, and the Tiktok will also be compressed after uploading. 1080P is the "sweet spot resolution" for short videos. In terms of frame rate, 30fps is suitable for most content, while 60fps is suitable for motion shots or images that require slow motion processing.
锁定曝光和对焦,避免画面“呼吸”。 手机默认的自动曝光和对焦,会在拍摄过程中不断调整,导致画面忽明忽暗、焦点漂移。拍摄前长按屏幕锁定曝光和对焦,画面稳定性会明显提升。
Lock exposure and focus to avoid "breathing" in the image. The default auto exposure and focus on mobile phones will constantly adjust during the shooting process, causing the image to flicker and the focus to drift. Long press the screen to lock exposure and focus before shooting, which will significantly improve image stability.
收音比画质更重要。 观众能忍受稍微模糊的画面,但忍受不了听不清的声音。手机内置麦克风在户外或嘈杂环境下收音质量很差,一个几十块的领夹麦克风就能显著提升声音清晰度。如果实在没有外接麦克风,拍摄时尽量靠近声源,后期用剪映的“降噪”功能处理。
Sound is more important than picture quality. The audience can tolerate slightly blurry images, but cannot tolerate inaudible sounds. The built-in microphone of a mobile phone has poor sound quality in outdoor or noisy environments. A lavalier microphone that costs only a few tens of yuan can significantly improve sound clarity. If there is really no external microphone, try to be as close to the sound source as possible during shooting, and use the "noise reduction" function of Jianying for post-processing.
光线是画质的“隐形参数”。 同样的手机,在窗边自然光下拍摄和在室内顶灯下拍摄,画质差距明显。自然光是非常便宜、非常好的光源。如果建议在室内拍,让光源在拍摄者前方(而不是后方),避免逆光。逆光拍摄时,手机自动曝光会让画面主体变成剪影。
Light is the 'invisible parameter' of image quality. The same phone shows a significant difference in image quality between shooting under natural light by the window and shooting under indoor ceiling lights. Natural light is the cheapest and best light source. If it is necessary to shoot indoors, place the light source in front of the photographer (not behind) to avoid backlighting. When shooting in backlight, the automatic exposure of the phone will make the subject of the picture become a silhouette.
