How to get better quality converting MP4 to WMV with FFmpeg?

Up vote6down votefavorite5

I am converting MP4 files to WMV with these II rescaling commands: ffmpeg -i test.mp4 -y -vf scale=-1:360 test1.wmvffmpeg -i test.mp4 -y -vf scale=-1:720 test2.wmv I ' ve also tried: ffmpeg -g 1 -b 16000k -i test1.mp4 test1.wmv however, the. wmv files that is produced is "blocky and grainy" as can see here in a small section of a video screenshot: These is the sizes: test.mp4 - 106 MBtest1.wmv - 6 MBtest2.wmv - 16 MB How can I increase the quality/size of the resulting WMV files (the size of the. wmv files are of no concern)?

can simply use the  -sameq  parameter ("Use same quantizer as source ") which produces a much larger sized video file (227 MB) but with excellent quality. ffmpeg-sameq-i test.mp4-y-vf scale=-1:360 test1.wmv shareimprove this answer answered  June "at 9:23 Edward tanguay224 572 875

7 A better solution is to use -qscale (or -qscale:v or -q:v depending on your syntax preference); generally with a value of 2-5. A lower value is higher quality, and 2 can be considered "visually lossless". -sameqis isn't designed to being used between formats that does not share the same quantizer scale, and this could be the case for You. –lordneckbeard June ' at 16:03 also you ' re applying  ; -sameq  as an input option (anything before  -i ). Probably works as expected, but keep on mind not all options applied to the input would be applied to the OUTPUT. –&NB Sp Lordneckbeard jun "at 16:07 -sameq has been removed. When you try to use it FFmpeg offers "Use-qscale 0 or a equivalent quality factor option", and it errors out with an inv Alid argument. –robert Koernke Jan 6 at 17:04 Add a Comment

One thing I discovered after many frustrating attempts of enhancing the final quality is if you don ' t specify a B Itrate, it ' ll use a quite low average. Try-b 1000k for a starting point, and experiment increasing or decreasing it until you reach the desired result. Your file would be quite bigger or smaller, accordingly.
