1) x264 doesn't support frame interpolation. You have to do it for yourself.<br><br>4) Using Avisynth, there's ChangeFPS or ConvertFPS which come built-in, <a href="http://compression.ru/video/frame_rate_conversion/index_en_msu.html">MSU Frame Rate Conversion</a>, or just try one of the many frame interpolation scripts for Avisynth in the Internet.<br>

<br>
I have some questions regarding the H.264 encoder and it would be great<br>
if some of you could spent a few minutes to answer them. I have to<br>
convert a video stream with 25 fps (PAL) to 29.97 fps (NTSC). Apart from<br>
changing resolution, I have some questions regarding converting the<br>
frame rate.<br>
<br>
1) Does the x264 encoder internally supports this frame rate conversion<br>
without changing the playback time ( so that 60sec of the original video<br>
in 25fps are also 60 sec with the new frame rate)? Or do I have to<br>
convert the framerate on the uncompressed video frames by myself?<br>
<br>
2) In case the x264 encoder supports frame rate conversion from<br>
25fps->29.97fps, which technique is used?<br>
<br>
3) In case the x264 encoder supports frame rate conversion from<br>
25fps->29.97fps, is it recommended to use it, or are there other<br>
techniques that are more recommended togehter with the x264 encoder?<br>
<br>
4) In case the x264 econder does NOT support frame rate conversion,<br>
could some of you recommend a technique or library for frame rate<br>
conversion from 25fps->29.97 which achievs a good quality?<br>
<br>
Thank you very much in advance.<br>
<br>
Best regards<br>
