I have a bunch of video files that are in the .RMVB format, which is suppose dto be Realplayer Movie or something anyhow, the Dingoo plays it but only the video no sound, I know it's just the movies cuz it works perfect for everything else. I took a guess that it's the audio bitrate or something thats the issue or maybe just the format anyhow I'm changing errr trying to change it to AVI as the output container, MPEG-4 as the Output Video Codec and Mp3 as the Output Audo Codec, I said the Video scale size to 320:240, the aspect to 4:3, FPS to 30, Bitrate to 192Kbps, I'm trying to get them as small as possible but still enjoy the movies, Just did one and it came out great but the RMVB format was like 33MB and the one I made was 44.5MB so I'm gunna try a possibly lower bitrate video, have to admit though it came out BADASS. thanks guy any other suggestions to save space, perhaps some formats use less space than others? Any ideas?
