品質を損なうことなくyoutube用のビデオを圧縮できますか?
yes. if your video is longer than 12 hours, or larger than 128gb, you need to reduce video size manually. or youtube will encode it with h.264 codec. but a large youtube video takes more time to load and upload. so you can use fvc free video compressor or imovie to reduce the mb size of a mov video.
