Re: [FFmpeg-user] Text quality (credits etc) in h264
Hi, > Normally I encode to a size of width 352 keeping aspect ratio, encoding to > 704 is better, but obviously far bigger files How many characters to fit in the frame? Those numbers are like something on my old gameboy... If increasing the width from 352 to 704 pixels is too expensive file-size wise, that means every 100kB matters, right? Is using the text itself not an option?

It seems to be an issue when the video is resized. Normally I encode to a size of width 352 keeping aspect ratio, encoding to 704 is better, but obviously far bigger files ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

Hi, > Are there any tips to maintain the quality of text in output files. > For example credits or slides in zoom videos. If mostly static text, or maybe for the credits, low constant motion, is most of the video content, I think multi-pass encoding would be beneficial. Or if you do not care about bitrate or filesize that much, you could keep lowering crf or set higher constant or target bitrate. Hard to recommend starting points without knowing pixel format for crf, and also dimensions for bitrate.
