Neither are encoders imo but see below. > Stream #0:0: Video: flv1 (flv) ([2][0][0][0] / 0x0002), yuv420p > Stream #0:0: Video: mpeg4 ( [0][0][0] / 0x0020), yuv420p I am surprised now: You wrote originally "I want to do screen recording [...] but the output file size is quite high". I was assuming that you meant lossless encoding in the rgb colourspace. For lossy encoding (flv1 and mpeg4 only support lossy encoding), you can get a smaller filesize by either specifying a lower bitrate or requesting a higher constant quantizer. As you already mentioned, the best lossy encoder (with acceptable encoding speed) is x264. If you want lossless encoding that keeps the original colourspace (rgb), please test png, ffv1, (ff)huffyuv and flashsv2. Then also test x264rgb with the lossless option. (The filesizes may be very significantly higher in all these cases than what you saw with the lossy encodings you tested, this is not unexpected. The files may be smaller depending on what you record.)
