MP4 source material

Post by Arthur »

Just got a Sony Cyber-shot M2 which records video in MP4 (mpegmovie 4TV) format.
Is it possible to use *.MP4 files directly in VideoStudio 9?
If not, to what format should I convert the MP4 files first and what program do you recommend do the conversion?

Regards,

Arthur

MPEG4 is a similar format to DivX or Xvid. it is a form of AVI that is very highly compressed producing a small file size yet maintains very high quality. It is especially good for videos you may wish to send to friends etc over the internet due to its small file size.

I have downloaded a few TV episodes off the internet which have the AVI extension which were in fact DivX or Xvid. I have found that if I play them back with Windows media Player or PowerDVD then the playback is a bit like the effect you get when watching something with a strobe light turned on - the picture appears to pause/jump every few frames.

After de-compressing these files to MPEG2, they play as smoothly as if they were live TV broadcasts. I put this down to the computer having to decompress them on the fly.

I would suspect that if you were to try and edit these MPEG4 files you would run into problems due to this high rate of compression.
It has been stated in many posts in these forums that it is always best to edit AVI files rather than MPEG files.
I would suggest you place "divxtoAVI" also "mpeg4 conversion" into a search engine such as google or Ask Jeeves and you will get lots of results.
