I first tried running it through WinFF but ffmpeg was giving me errors (header and sync messages).
#INTERVIDEO AC3 CODEC MOVIE#
The second movie had an AC3 audio stream (48000 Hz, 192 kb/s). Everything (video, audio, sync) was perfect. I ran the converted output through SMC and watched portions of the movie on my Sansa. I ran the corrected source in WinFF and this time, the ffmpeg log was clean. I accepted and saved a corrected copy of the source avi. I loaded the source in a freeware called AviDemux which warned me right away that the index had to be rebuilt and offered to do it for me. The ffmpeg window was giving messages about “sync errors”. It looked like a very straightforward job, but it wasn’t. The first movie had a standard 128bit mp3 audio stream. Watch the DOS window (ffmpeg) carefully for error messages (see below). Add the source avi in the list of files to convert, select Convert To… the preset name (Sansa) and label (e200v2 AVI), set the output folder and press Convert. Click Edit/Presets, enter a name (Sansa), a label (e200v2 AVI), copy the string into the command line and enter “avi” in the extension.
The first challenge was setting up WinFF with the preset you provided. It looked serious enough, so I tried it with a couple of avi movies. Just when I was ready to quit on videos because of the dreaded sync issues, I stumbled on your post. Message Edited by themichael on 01-13-2009 11:52 PM I encoded two files with the same settings in a different encoder, the header was different in each file. Every file has the exact same header structure when using SMC. SMC has its own “private” codecs ( 3G to Divx to Ulead) which explains its inability to convert files I have codecs for.ĭigging deep into video encoding I have discovered that the player is maybe looking for a very specific RIFF structure in the avi file. If it played in VLC it would run thru WinFF and convert in SMC. Feed the files thru WinFF with this as a preset -r 20 -vcodec mpeg4 -vtag DX50 -s 224x176 -aspect 1.273 -b 700k -qmin 3 -qmax 5 -mbd 2 -bf 2 -flags +4mv+trell -aic 2 -cmp 2 -subcmp 2 -bf 0 -acodec libmp3lame -ar 44100 -ab 128k -ac 2 and avi extension. Side note: found fix for audio sync and format acceptance problems. Only the ISTF field is filled, InterVideoĮncoding to this format gets a warning from the player to use SMC. After some SERIOUS digging I have the format for the e200v2 player:īitrate 700k (way to high for this resolution, up to 25 percent file size increase)
