直通输出与采集画质常有取舍：部分卡直通支持4K120但采集录制只能4K60/1080p120，需分清'直通规格'与'采集规格'两套参数，商家宣传的最高数字往往是直通值

Unverified采集卡规格越高（4K60直通+采集）延迟处理越复杂且价格陡增，1080P60足够绝大多数直播平台（B站/斗鱼推流上限也常低于源画质），4K采集仅适合本地精剪存档79% similarUnverified标称'4K'的低价采集卡多为'4K输入+1080p采集'（4K仅直通不录制），真正录制4K需明确标注'4K60 capture/record'，购买前务必区分输入分辨率与采集分辨率参数77% similarUnverified采集卡标注的"4K60 pass-through"（直通/穿透）与"4K60 capture"（采集）是两个不同规格，很多百元卡只支持4K直通但采集仅1080P30，购买前必须分开确认两个参数75% similarUnverified80GB容量对4K/8K高码率视频录制偏小，长时间拍摄或多机位工作建议选更大容量或备多张卡75% similar
