free video converter software

I have looking on the internet to find free video conveter but most of them have said they are free but after downloading we need to buy.It looks like a bullshit websites any way i have came up with some sites that they give a free trial to use software

mp4 converter is another software where they give you a trial you can download from their website

another is Aneesoft free mpeg converter which is available at softpedia you can search at and download it

their are more sites that offer for money such as xilisoft video converter.danjusoft video converter.

They can Convert video to MPEG/WMV/AVI and other popular formats as MP4, FLV, 3GP, ASF, MOV, M4V, MPG, VOB, XviD, MKV, M2TS, TS, TRP, AVCHD with fast speed and amazing quality.

I suggest to you use a free trial and see if it suits for your needs since you cant get money after buying anything so try the free ones
