problem in sony vegas with FFmpeg x264 conversion

[gil900]

Hello.
i tried to convert an uncompressed video to compressed x264 avi video with this FFmpeg command:

ffmpeg.exe -i test.avi -c:v libx264 -preset medium -crf 15 -c:a copy output_test.avi

this was converted the video to what i want but there is a problem with dropped frames in sony vegas.
it is happen only in vegas and i noticed that it is happen when there is a dropped frame..

this is what happen:


i know that it is happen on dropped frames because i tried to convert this also with the normal x264vfw encoder in VirtualDub.
and i sow that this problem not happen but i see that there is a dropped frame/s..

i don't know why it is happening...


Please help me!
Thanks for helpers!

Please do not tell me how to work.

I want to convert it ..

Can i get help please?

wtf? if you are going to work in vegas why convert it first. it makes no sense as you are going to have to render it out of vegas anyway.

There's a very good reason ..

I can not explain it with my English.
But it allows me to work much faster ..

It is very important for me. And quality Almost the same thing.

Please help me with this problem. I do not need to be told how to work.

try it my way. see if the same problem shows up. it is not dropped frames. if you need to use an intermediate file for a slow computer use a lossless codec like lagarigth or while the original is in vegas render it out as sony yuv. h264 is a delivery format not an editing format.

I do not have no problems with playing x264 compressed video in sony vegas.
yes, It is true that I had a problem in the past

And you did not help me .. You told me about the same thing - that i Need a powerful computer to play compressed x264 videos in sony vegas.

But any way, I solved the problem.
by uninstall Adobe Premiere and all my codec packs and install only the codec x264vfw.. after that sony vegas playes it perfectly Without the need for a strong computer.

and this is a drooped frame.
I checked it in VirtualDub by frame by frame view..
and i see the drooped frame even in the uncompressed video in sony vegas..
so it is not because my computer is slow. it is because the reason that this is the video..

and this problem I showed the picture in not because my computer is slow. it is because of the conversion.
in is not happan with the x264vfw conversion(not by ffmpeg). when i use the x264vfw conversion, so the video play in sony vegas Exactly the same like the uncompressed video - Without stopping and with the drooped frame in the same time..

i hope that now all is clear

Do not think I'm nervous ..
I am very happy that I knew the forum.

I solved the problem myself ..

I had to add the FPS rate to my video in my Command:
ffmpeg.exe -r 25 -i test.avi -vcodec libx264 -preset medium -crf 15 -threads 0 -c:a copy -r 25 output_test.avi

i took an example from here:
http://ffmpeg.org/ffmpeg.html#image2-2
in "2. Description" section of the guide

Programs often have trouble with out of order decoding in AVI files. Maybe if you disable b frames in the x264 encoder.

I solved the problem .. Thanks anyway ..
I still can not believe I solved that problem alone .. But it seems that it solved the problem! I tested it a few times now.

Glad it worked out.

For future reference, a simple mediainfo output on the original file would have saved you a lot of grief. The vfr would have jumped out.

It seems that i have a problem with the Audio according to VLC Media Player!

i don't know why it is happen...
the audio is out of sync
in the original video is fine.


why it is happan?
this is the Command i am using:

-r 25 -i <Input> -vcodec libx264 -preset medium -crf 15 -c:a copy <Output>.avi
