hi,
i want to transcode a 1920x1080 mts file with ffdshow h.264 codec.
but every time i start the encoding process the output video only starts to show the preview after 45-60 frames. the source file has already gone 45-60 frames after the output file is being written. i can see that in the avi file afterwards: about 2 seconds of that source file are missing at the beginning!
same thing at the end of the encoded video: 1-2 sec are missing aswell.
i tried it with different codecs (xvid, mpeg4, ...) - there is no delay at all and no frames were dropped at the end.
is there a problem with that codec? any special option i have missed?
is there another place/forum where people could help?
thanks in advance

- Possibly.
Download another version/newer build at a later time and compare. Defective builds happen from time to time, I've seen one with H264 totally broken.
Another way -- download "MMX version" instead of "SSE", or unoptimized instead of MMX -- the lesser optimizations the more reliable FFDShow is.
Find out which "***-optimized version" is reliable enough on your computer (by trial-an-error) and stay with it in future.
---
Do not delete older version of FFDShow before you are sure the new/updated works OK.
Any update is experimental.
...But when they work - they are fine... |

I personally use the x264 vfw version codec. I never had luck with ffdshow's version of that codec. Either with compression or the lossless ffdshow version of H264 I had always gotten either garbled, psychedelic-like, video or spotty and artifacted video.
I have tried so many different builds up to recent ones and had never been happy with their H264 codec. I have noticed that my situation doesn't happen with everyone so I'm not sure why these things have happened in my, or others, condition.
I just redid windows on a newer hard drive not long ago and only install codecs I only need and my system checks out fine so I don't know why this problem with ffdshow's H264 exists even currently for me.
x264 vfw codec:
http://sourceforge.net/projects/x264vfw/
That is the codec I use for h264. If anyone has trouble using ffdshow's version, that is the one to get.
